TY - JOUR. T1 - Repeated amphetamine administration alters the expression of mRNA for AMPA receptor subunits in rat nucleus accumbens and prefrontal cortex. AU - Lu, Wenxiao. AU - Chen, Huiyuan. AU - Xue, Chang Jiang. AU - Wolf, Marina E.. PY - 1997/7. Y1 - 1997/7. N2 - Recent evidence suggests that behavioral sensitization to amphetamine is associated with alterations in excitatory amino acid (EAA) transmission in perikarya (ventral tegmental area) and terminal regions (nucleus accumbens [NAc]) of the mesoaccumbens dopamine system. The present study determined whether repeated amphetamine administration alters expression of mRNAs for AMPA receptor subunits. We studied the NAc, because it is the site of expression of amphetamine sensitization, and the prefrontal cortex (PFC), because it is the origin of EAA projections that regulate the mesoaccumbens dopamine system. Rats were treated for 5 days with 5 mg/kg/day amphetamine sulfate or vehicle (controls) and perfused 3 or 14 days after the last ...

TY - JOUR. T1 - Individual differences in amphetamine sensitization, behavior and central monoamines. AU - Scholl, Jamie L.. AU - Feng, Na. AU - Watt, Michael J.. AU - Renner, Kenneth J.. AU - Forster, Gina L.. PY - 2009/3/2. Y1 - 2009/3/2. N2 - Repeated amphetamine treatment results in behavioral sensitization in a high percentage of rats. Alterations to plasma corticosterone, neural monoamines and stress behavior can accompany amphetamine sensitization. Whether these changes occur following repeated amphetamine treatment in the absence of behavioral sensitization is not known. Male Sprague-Dawley rats were treated with amphetamine (2.5 mg/kg, i.p.) or saline once daily for 6 days. Amphetamine-induced locomotion and stereotypy, open-field anxiety behavior, plasma corticosterone and limbic monoamines were measured during withdrawal. Sixty-two percent of amphetamine-treated rats showed behavioral sensitization over the test periods. Only amphetamine-sensitized rats showed increased latency to ...

TY - JOUR. T1 - Differential development of autoreceptor subsensitivity and enhanced dopamine release during amphetamine sensitization. AU - Wolf, Marina. AU - White, F. J.. AU - Nassar, R.. AU - Brooderson, R. J.. AU - Khansa, M. R.. PY - 1993/1/1. Y1 - 1993/1/1. N2 - Various changes in the function of dopamine neurons have been proposed to underly the development of behavioral sensitization to the locomotor stimulant effects of d-amphetamine. The present study examined the relative importance of two such mechanisms after both short (3-4 days off) and longer (10-14 days off) withdrawals from repeated amphetamine or saline injection (1 mg/kg/day, days 1-5 and 8-12). First, single-unit recording was used to examine the sensitivity of impulse-regulating somatodendritic autoreceptors located on mesoaccumbens dopamine neurons in the rat ventral tegmental area. Second, in vivo microdialysis was used to examine the ability of amphetamine challenge to increase extracellular dopamine levels in the rat ...

A substantial increase in substance treatment episodes for methamphetamine problems suggests characteristics of the treatment population could have changed and that targeted treatment programs are required. To determine who methamphetamine treatment should be designed for this study has two aims. First, to empirically describe changes in amphetamine treatment presentations to a rural NSW drug and alcohol treatment agency over time. Second, to examine how these characteristics may affect the likelihood of being treated for amphetamines compared to other drugs. The Australian Alcohol and Other Drug Treatment Services National Minimum Data Set (AODTS-NMDS) containing closed treatment episodes from a single agency from three time periods was used. Characteristics of people receiving amphetamine treatments in these three periods were compared and the effects of these characteristics on the odds of being treated for amphetamine were estimated using a logistic regression model. The characteristics utilised in

Please read the label you buy from the label so you know the dosage and what kinds of Amphetamine you need. Drugs made by mixing Amphetamine with other types of illegal medicines, such as tobacco or tobacco products. It is important for us to understand drug-related disorders so we can be on the safe side or being careful that you dont become ill because amphetamine gives you painkillers. Amphetamine are also known as anorexic drugs. They may cause an overdose of many substances, which increases the risk for serious problems. Amphetamine is sometimes found in certain medicines (e.g. alcohol, tea, heroin and alcohol). Amphetamine may be found in chewing gum, chewing alcohols, gum for chewing, e.g. Nicotine in e.g. prescription prescription nicotine, is not as effective, sometimes, as in amphetamine, which can cause a high blood nicotine level such as about 0.5 mg/100 ml. Amphetamine can also be taken as an anti-depressant drug. An occasional withdrawal from any of the four types of Amphetamine will

Amphetamine detox is only the first step in addiction treatment.Amphetamine detox is only the first step in addiction treatment. Without regular, long-term treatment in conjunction with amphetamine detox, many users will return to abusing the drug. Treatment may be provided on an inpatient or outpatient basis. Each person is different, and having a treatment plan tailored to each persons specific situation increases the chances of a good outcome. Support groups such as Narcotics Anonymous can be helpful to some people going through an addiction. Supportive family and friends increase the chances of a successful recovery. Addiction is a chronic disease that needs long-term treatment.. According to the TEDS report, amphetamine treatment admission rates increased between 1993 and 1999 by 250 percent or more in 14 states and by 100 to 249 percent in another 10 states. There are many treatment options available that can be tailored to your specific situation. Amphetamine addiction treatment is not ...

Amphetamine has complex behavioral actions in the rat that depend upon the release of dopamine in striatal and mesolimbic brain regions. To explore a possible role of the dopamine-sensitive cAMP second-messenger system in mediating these effects, we examined the effects of in vivo amphetamine treatments on the D1 receptor-coupled adenylate cyclase system in membranes from striatal and mesolimbic rat brain regions. The results show that amphetamine produces a regional, dose- and time- dependent down-regulation of adenylate cyclase activity. Intermediate and high doses of amphetamine (2.5 and 7.5 mg/kg, respectively), but not a low dose (1.0 mg/kg), resulted in a decrease in the apparent Vmax and/or an increase in the apparent Ka for the selective D1 partial agonist, SKF38393, in striatal membranes 30 min after amphetamine treatment. Treatment of rats with 7.5 mg/kg amphetamine for 30 and 60 min, but not 10 min, similarly resulted in a down-regulation of D1- mediated adenylate cyclase activity in ...

Amphetamines are stimulants that speed up the bodys system. Many are legally prescribed and used to treat attention-deficit hyperactivity disorder (ADHD). Street names include Bennies, Black Beauties, Crank, Ice, Speed and Uppers. Amphetamines can look like pills or powder. Common prescription amphetamines include methylphenidate (Ritalin® or Ritalin SR®), amphetamine and dextroamphetamine (Adderall®) and dextroamphetamine (Dexedrine®).. Amphetamines are generally taken orally or injected. However, the addition of ice, the slang name of crystallized methamphetamine hydrochloride, has promoted smoking as another mode of administration. Just as crack is smokable cocaine, ice is smokable methamphetamine. The effects of amphetamines and methamphetamine are similar to cocaine, but their onset is slower and their duration is longer. In contrast to cocaine, which is quickly removed from the brain and is almost completely metabolized, methamphetamine remains in the central nervous system ...

AU - Fernández-Teruel, Alberto. AU - Driscoll, Peter. AU - Giorgi, Osvaldo. PY - 2005/2/10. Y1 - 2005/2/10. N2 - The mesolimbic dopamine system is considered to play a pivotal role in the locomotor activation produced by psychostimulants and in the augmentation of this effect observed upon repeated drug administration, a process denominated behavioral sensitization. The selective breeding of Roman high- (RHA) and low-avoidance (RLA) rats, respectively, for rapid versus poor active avoidance acquisition has resulted in two phenotypes that differ in the functional properties of the mesolimbic dopamine system and in their behavioral and neurochemical responses to addictive drugs, including psychostimulants and opiates. Hence, the present study was designed to compare the ability of these lines to develop ...

BACKGROUND: Acute depletion of tyrosine using a tyrosine-free amino acid mixture offers a novel dietary approach to inhibit activated dopamine pathways in the brain. This study investigated the potential of in vivo functional magnetic resonance imaging (fMRI) methods as a noninvasive means to detect effects of tyrosine depletion on dopamine function. METHODS: Changes in blood-oxgenation level dependent (BOLD) contrast induced by administration of the dopamine-releasing agent, amphetamine (3 mg/kg i.v.), were measured in halothane-anaesthetised rats. RESULTS: Amphetamine evoked changes in BOLD signal intensity with the greatest effects observed in the nucleus accumbens (-7.7%), prefrontal cortex (-13.6%), and motor cortex (+12.5%). Pretreatment with a tyrosine-free amino acid mixture attenuated the response to amphetamine in some regions (nucleus accumbens and prefrontal cortex), but not others (motor cortex). Amphetamine itself had no effect in thalamus and hippocampus but, surprisingly, increased the

PY - 1991/2/22. Y1 - 1991/2/22. N2 - The purpose of this study was to determine the cerebral regional microvascular and vascular responses to amphetamine sulfate at a dose (5 mg/kg) known to affect neuronal function. Cerebral blood flow (14C-iodoantipyrine method) and percent of perfused capillaries (fluorescein isothiocyanate-dextran and alkaline phosphatase staining method) were determined during control and after intravenous administration of amphetamine in conscious Long-Evans rats. Amphetamine caused an increase in blood pressure (34%) and heart rate (31%). There was a significant increase in averaged cerebral blood flow from 98 ±8to 166±9 ml/min/100 g after amphetamine. This flow increase was significant in the cortex, basal ganglia, pons and medulla, however the increase was not significant in the ...

A sample of 985 self-admitted amphetamine users was compared with a sample of airmen who had no known record of drug abuse. Results of this study indicate that there is a very strong likelihood for amphetamine users to abuse other drugs. There are relationships between amphetamine use and geographic area of enlistment, religious preference, aptitude scores, educational level, and age at enlistment. Amphetamine use is also related to the likelihood of getting an undesirable discharge and to lower APR ratings. (Author)*Amphetamines

Background: Psychotic states related to psychostimulant misuse in patients with hepatitis C virus infection may complicate acceptance and reaction to antiviral treatment. This observation equally applies to widely used ribavirin therapy. Objective: We examined psychomotor and body weight gain response to low ribavirin doses after cessation of intermittent amphetamine treatment in adult rats to assess its role in neurobehavioral outcome during psychostimulant withdrawal. Method: The model of amphetamine-induced (1.5 mg/kg/day, i.p., 7 consecutive days) motor sensitization and affected body weight gain was established in adult male Wistar rats. Then, additional cohort of amphetamine-sensitized rats was subjected to saline (0.9% NaCl; 1 mL/kg/day; i.p.) or ribavirin (10, 20 and 30 mg/kg/day, i.p.) treatment for 7 consecutive days. Animals motor activity in a novel environment was monitored after the 1st and the 7th saline/ribavirin injection. Body weight gain was calculated as appropriate. ...

This report describes a series of experiments, all of which demonstrate a strong contribution of the behavioral pattern manifested at the time of initial amphetamine injection to the topography and development of the stereotypy that develops with chronic amphetamine intoxication. These initial behavioral patterns reflect (i) learned behaviors, (ii) species-specific behaviors, (iii) behaviors associated with amphetamine arousal, and (iv) novel behaviors reflecting unique environmental circumstances prevailing at the time of administration. In an experiment using eight dogs administered amphetamine in a situation which allowed interaction between the animals, the behavioral stereotypies that developed were comprised of the social interaction patterns ongoing at the time of initial drug effects. Experiments with rats have demonstrated that the configuration of the enclosure in which they are injected influences the initial behavioral reactions to amphetamine and thus modifies the stereotypy.

Background: Multiple sclerosis (MS) is an autoimmune disorder that results in debilitating cognitive impairment in 40-65% of patients. There are no current treatments for this symptom of MS. This is a systematic review of literature on the impact amphetamines have on cognitive function of MS patients. Methods: An exhaustive search of available medical literature was conducted using MEDLINE-Ovid, MEDLINE-PubMed, Web of Science, and CINAHL. Keywords used included: amphetamines and multiple sclerosis. Relevant articles were assessed for quality using GRADE. Results: Three studies have statistically significant improvements in some aspects of cognitive function in patients on amphetamines when compared to placebo. However, a high rate of adverse events were noted with L-isomer or D-isomer amphetamines alone. Conclusion: Amphetamines positively impact cognitive function in MS patients. Mixed amphetamine salts extended release (MAS-XR) seemingly have the lowest rate of adverse effects with the greatest

Rats were trained in a two-lever food-reinforced operant task to discriminate (+)-amphetamine (1 mg/kg) from saline. After discrimination training stabilized, test doses of (+)-amphetamine (0.0625-2.0 mg/kg), (-)-nicotine (0.1-1.0 mg/kg), or (-)-nornicotine (1-10 mg/kg) were assessed for their ability to substitute for the (+)-amphetamine training dose during brief test sessions in which food reinforcement was withheld. As expected, as the test dose of (+)-amphetamine increased, there was a dose-related increase in drug-appropriate responding, with both 1 and 2 mg/kg test doses substituting fully for the (+)-amphetamine training dose. Both (-)-nicotine and (-)-nornicotine showed partial substitution (approximately 50% drug-appropriate responding) for the (+)-amphetamine training dose, with (-)-nicotine being more potent than (-)-nornicotine. Rate suppressant effects prevented the assessment of higher doses of (-)-nicotine or (-)-nornicotine. Thus, while (-)-nicotine and (-)-nornicotine share ...

People who use amphetamines could be at an increased risk of developing Parkinsons disease. Apart from their illegal use amphetamines such as Benzedrine and Dexedrine are often prescribed for people with attention-deficit hyperactivity disorder (ADHD) and narcolepsy, as weight-loss pills and are also used to treat traumatic brain injury. Researchers from the U.S. health organisation Kaiser Permanente studied 66,348 people who were initially studied between 1964 and 1973 and re-evaluated in 1995. 1,154 people had been diagnosed with Parkinsons by the end of the study. The participants were asked about their use of amphetamines - either as weight-loss pills or in the form of Benzedrine or Dexedrine. There was no increase in risk for the people who used amphetamines for weight loss but those who took Benzadrine or Dexedrine were nearly 60% more likely to develop Parkinsons. Amphetamines are known to affect the release and uptake of dopamine, the most important neurotransmitter involved in ...

Heightened distractibility is a core symptom of Attention Deficit Hyperactivity Disorder (ADHD). Effective treatment is normally with chronic orally administered psychostimulants including amphetamine. Treatment prevents worsening of symptoms but the site of therapeutic processes, and their nature, is unknown. Mounting evidence suggests that the superior colliculus (SC) is a key substrate in distractibility and a therapeutic target, so we assessed whether therapeutically-relevant changes are induced in this structure by chronic oral amphetamine. We hypothesized that amphetamine would alter visual responses and morphological measures. Six-week old healthy male rats were treated with oral amphetamine (2, 5 or 10 mg/kg) or a vehicle for one month after which local field potential and multiunit recordings were made from the superficial layers of the SC in response to whole-field light flashes in withdrawal. Rapid Golgi staining was also used to assess dendritic spines, and synaptophysin staining was ...

While you might imagine amphetamine addiction to be one of the issues you would see on television instead of affecting someone you are about in real life, it is an all too common problem among people of all ages. Amphetamines can be legitimately prescribed to people for certain issues like ADHD (Attention Deficit Hyperactivity Disorder), but it can be also be abused. What Are Some Commonly Abused Amphetamines? There are several common amphetamine drugs that are quote commonly illicitly used. Adderall is a prescription amphetamine often used to treat patients with attention deficit or hyperactivity disorders. It can be prescribed in several different strengths, which makes the higher strength of 30mg pills much more valuable to people who abuse it often. Methamphetamine is a drug that is often prescribed under the name Desoxyn, but it is also one that is commonly created by folks who might gather up a lot of chemicals necessary to make it themselves, which can lead to dangerous and addictive ...

Amphetamines Powder are synthetic stimulants. Their current medical use is limited, with only Dexedrine (dexamphetamine sulphate) currently available for use in the treatment of narcolepsy - where the patient cannot help suddenly falling asleep. The only other amphetamine-related drug available for medical use is methylphenidate (Ritalin) for the treatment of attention deficit syndrome in ...

Amphetamine is a psychostimulant drug, known to produce increased wakefulness and focus in association with decreased fatigue and appetite. Clinical uses of amphetamine include chronic administration for the treatment of narcolepsy in adults and attention-deficit/hyperactivity disorder in children [1]. It is also used as a drug of abuse [2]. Amphetamines are well absorbed from the gastrointestinal tract and metabolized by deamination, oxidation and hydroxylation. Approximately 90% of the dose is excreted in the urine within 3-4 days [1]. An amphetamine overdose is rarely fatal but can lead to a number of different symptoms, including psychosis, chest pain and hypertension. Cardiovascular effects include increased heart rate and blood pressure, chest pain, myocardial ischemia or infarction, dysrhythmias, cardiovascular collapse and death [2].. A typical postmortem toxicological analysis is identification of the drugs or chemicals presence in postmortem specimens [3]. Blood, urine, bile, liver and ...

Adderall XR is an extended release form of the amphetamine based drug Adderall, which is commonly used in the 21st century to treat Attention Deficit Hyperactivity Disorder and the rare sleeping disorder narcolepsy.. Adderall is a trade name for the drug, which is more commonly known as amphetamine mixed salts and has grown in popularity in recent years following its initial approval for use in the U.S. as an obesity treatment.. Amphetamine mixed salts were first created and approved for use in January 1960 under the brand name Obetrol; the mixture of amphetamine and dextroamphetamine salts is know to have a common side effect of weight loss leading to the drug being used in the first instance as an obesity treatment.. In the 21st century this is not a common use, but some physicians do still prescribe Adderall for those wishing to lose weight. Following the rise of the medical condition known as ADHD a form of amphetamine mixed salts was introduced specifically for treating the condition under ...

Gene-environment interactions play a significant role in drug abuse and addiction. Epigenetics (the study of how environmental stimuli alter gene expression) has gained attention in recent years as a significant contributor to many behavioral phenotypes of drug addiction. The current study sought to determine if differential rearing conditions can alter a specific epigenetic mechanism, histone deacetylase (HDAC), and how HDAC inhibition can affect drug-taking and drug-seeking behaviors differently among enriched, isolated, or standard-housed rats. Ninety male Sprague-Dawley rats were reared for 30 days in enriched (EC), isolated (IC), or standard (SC) conditions prior to amphetamine (0.03, 0.05, 0.1 mg/kg/infusion, i.v.) self-administration, extinction, or reinstatement sessions. Trichostatin A (TsA; 0.3 mg/kg, i.v.), an HDAC inhibitor, was injected 30 min prior to drug-taking or drug-seeking sessions. Results indicated that EC rats self-administered less amphetamine (0.03 mg/kg/infusion) than ...

Overindulging is never a good thing. I am sure your Sim will snort like a responsible adult, but if that is not the case, here are some of the side effects that might occur.. Speed Freak. Sims who keeps on snorting a ton of amphetamine over a prolonged period of time will eventually get an Addicted to Amphetamine buff. This buff lasts for 5 days and is refreshed every time your Sim snorts more amphetamine. If your Sim is not under the influence while the buff is active, he or she might get a lot of negative debuffs until he or she snorts more amphetamine. Your Sim will also loose a lot of weight quite rapidly while addicted.. Overdosing. If your Sim snorts too much amphetamine in the same sitting he or she might experience a non-fatal or fatal OD. Fatal ODs are much less common than non-fatal ones. If your Sim has a non-fatal OD, the energy levels will plummet and he or she will eventually pass out. If your Sim experience a fatal OD, however… Well… Game over.. ...

Drug-dependent neural plasticity related to drug addiction and schizophrenia can be modeled in animals as behavioral sensitization, which is induced by repeated noncontingent or self-administration of many drugs of abuse. Molecular mechanisms that are critical for behavioral sensitization have yet to be specified. Long-term depression (LTD) of alpha-amino-3-hydroxy-5-methyl-isoxazole-4-propionic acid receptor (AMPAR)-mediated synaptic transmission in the brain has been proposed as a cellular substrate for learning and memory. The expression of LTD in the nucleus accumbens (NAc) required clathrin-dependent endocytosis of postsynaptic AMPARs. NAc LTD was blocked by a dynamin-derived peptide that inhibited clathrin-mediated endocytosis or by a GluR2-derived peptide that blocked regulated AMPAR endocytosis. Systemic or intra-NAc infusion of the membrane-permeable GluR2 peptide prevented the expression of amphetamine-induced behavioral sensitization in the rat. ...

Psychostimulant drugs addiction is a chronic public health problem and individuals remain susceptible to relapses increasing public expenses even after withdrawal and treatment. Our research group has focused on finding new therapies to be employed in drug addiction treatment, suggesting the physical exercise as a promising tool. This way, it is necessary to know the mechanisms involved in the beneficial influences of physical exercise observing the pathway that could be explored in drug addiction treatment. Male Wistar rats were conditioned with amphetamine (AMPH) following the conditioned place preference (CPP) protocol and subsequently submitted to swimming for 5 weeks (1 h per day, 5 days per week). Half of the animals were injected with Naloxone (0.3 mg/mL/kg body weight, i.p.) 5 min prior each physical exercise day. After AMPH-CPP re-exposure, our outcomes showed that physical exercise, in addition to minimizing the relapse behavior in the CPP, it increased D1R, D2R and DAT in the Ventral ...

d-Amphetamine is markedly more potent an inhibitor of catecholamine uptake by norepinephrine neurons in the brain than is 1-amphetamine, whereas the two isomers are equally active in inhibiting catecholamine uptake by the dopamine neurons of the corpus striatum. In behavioral studies, d-amphetamine is ten times as potent as 1-amphetamine in enhancing locomotor activity, while it is only twice as potent in eliciting a compulsive gnawing syndrome. This suggests that the locomotor stimulation induced by amphetamine involves central norepinephrine, while dopamine neurons play an important role in the induced compulsive gnawing behavior. Assessment of differential actions of d- and 1-amphetamine may be an efficient method to differentiate behaviors involving norepinephrine or dopamine in the brain. ...

Prevalence is defined as the number of cases of a given disease in a specified population at a designated time per 100,000 people. Amphetamine dependence is a substance-related disorder involving a dysfunctional pattern of amphetamine use. Included in the GBD disease modelling were cases meeting the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) or the International Classification of Diseases (ICD-10) diagnostic criteria for amphetamine dependence (DSM: 304.40; ICD: F15.2), excluding those cases due to a general medical condition. According to DSM-IV TR criteria, dependence involves a maladaptive pattern of substance use leading to clinically significant impairment or distress.. ...

Amphetamine was discovered over 100 years ago. Since then, it has transformed from a drug that was freely available without prescription as a panacea for a broad range of disorders into a highly restricted Controlled Drug with therapeutic applications restricted to attention deficit hyperactivity disorder (ADHD) and narcolepsy. This review describes the relationship between chemical structure and pharmacology of amphetamine and its congeners. Amphetamines diverse pharmacological actions translate not only into therapeutic efficacy, but also into the production of adverse events and liability for recreational abuse. Accordingly, the balance of benefit/risk is the key challenge for its clinical use. The review charts advances in pharmaceutical development from the introduction of once-daily formulations of amphetamine through to lisdexamfetamine, which is the first d-amphetamine prodrug approved for the management of ADHD in children, adolescents and adults. The unusual metabolic route for ...

Even if you only use drugs occasionally, other factors such as dosage amount and length of time using can affect how long amphetamine withdrawal lasts.

Two experiments were conducted to determine whether cross-sensitization/tolerance between wheel running and the drugs amphetamine and morphine is possible in male Sprague Dawley rats. Each experiment compared a non-wheel control group and a chronic wheel access group of rats. Following a 24 day period of wheel access all animals were presented with a drug and saline challenge test (counterbalanced) with either 1 mg/kg of amphetamine (Experiment 1) or 10mg/kg or morphine (Experiment 2). Prior to the challenge tests all animals were habituated to the novel testing environment in two 1 hr sessions (Experiment 1) or one 2 hr session (Experiment 2) to attenuate the acute motoric response to a novel environment. Behavioral sensitization/tolerance was measured by locomotion (cm) within long narrow activity boxes with the Ethnovision video tracking system. In the first experiment the wheel access rats were significantly more active during the 1 hr amphetamine challenge test than the non-wheel rats thus showing

TY - JOUR. T1 - Strain-dependent behavioural sensitization to amphetamine. T2 - Role of environmental influences. AU - Cabib, S.. PY - 1993. Y1 - 1993. N2 - Repeated daily pairings of 1 mg/kg of amphetamine and test environment induced a large, significant increase of locomotion in mice of the C57BL/6 strain, while a slight, non-significant increase was observed in mice of the DBA to amphetamine in the test cages when the drug was repeatedly administered in their home cage. Moreover, C57BL/6 but not DBA/2 mice showed conditioned hyperactivity. Subsequently six daily pairings of saline and test cage produced a slight, non-significant reduction of the hyperactive response shown by C57BL/6 mice, accompanied by a further increase in the behavioural effect of amphetamine. Finally, a similar, significant context-independent sensitization (unpaired vs control) was observed in mice of the two strains subjected to pairings of saline with the test cage; while context-dependent sensitization (paired vs ...

The instant invention is directed toward an immunoassay which can determine the presence of amphetamines in a sample suspected of containing amphetamine and/or methamphetamine by employing at least two conjugates, each comprised of a functionally similar label bound to an amphetamine analog and a methamphetamine analog respectively and an antibody to amphetamine and an antibody to methamphetamine wherein at least one of the antibodies is a monoclonal antibody.

The American Academy of Pediatrics doesnt even have guidelines for amphetamine prescription for children below 4 years old. However, it can be expected that at such a young age, children will quickly develop a dependence on these drugs, setting the state for addiction to other amphetamines later in life including methamphetamine.. That is exactly what happens to a lot of people who use amphetamines, methamphetamine. Just imagine how badly a human being would be messed up if they did amphetamines starting at age 2.. A recent survey found that 7.5% of children ages 6-17 are currently on prescription medications for some type of mental illness, ADHD medications make up 80% of them.. This has to stop. It seems in American society today, the gap between the consciousness levels of people is getting wider. In other words, it seems a certain part of our population is getting more and more aware, intelligent, conscious, and deliberate of their actions. At the same time, another part of our population ...

TY - JOUR. T1 - Alterations in subcellular expression of acid-sensing ion channels in the rat forebrain following chronic amphetamine administration. AU - Suman, Ajay. AU - Mehta, Bhavi. AU - Guo, Ming Lei. AU - Chu, Xiang Ping. AU - Fibuch, Eugene E.. AU - Mao, Li Min. AU - Wang, John Q.. PY - 2010/9. Y1 - 2010/9. N2 - Acid-sensing ion channels (ASICs) are densely expressed in broad areas of mammalian brains and actively modulate synaptic transmission and a variety of neuronal activities. To explore whether ASICs are linked to addictive properties of drugs of abuse, we investigated the effect of the psychostimulant amphetamine on subcellular ASIC expression in the rat forebrain in vivo. Repeated administration of amphetamine (once daily for 7 days, 1.25. mg/kg for days 1/7, 4. mg/kg for days 2-6) induced typical behavioral sensitization. At a 14-day withdrawal period, ASIC1 protein levels were increased in the defined surface and intracellular compartments in the striatum (both caudate putamen ...

THURSDAY, Oct. 26, 2017 (HealthDay News) - Adolescents appear to underreport their nonmedical amphetamine use, which may be in part due to lacking awareness that Adderall is an amphetamine, according to a study published online Oct. 23 in Drug and Alcohol Dependence.. Joseph J. Palamar, Ph.D., M.P.H., from New York University Langone Medical Center, and Austin Le, from New York University College of Dentistry, examined self-reported nonmedical Adderall and amphetamine use in a nationally representative sample of 24,740 high school seniors participating in the Monitoring the Future study (2010-2015). They analyzed prevalence and correlates of discordant responses among past-year Adderall users, defined as reporting past-year nonmedical Adderall use but not past-year nonmedical amphetamine use..

Amphetamines are a group of nervous system stimulants that includes amphetamine, dextroamphetamine, and methamphetamine. They are used to induce a state of alert wakefulness and euphoria, and since they inhibit appetite, they also serve as diet pills. After World War II, they were widely prescribed by physicians as diet pills, but they are generally no longer recommended for weight loss programs since there are too many hazards in the prolonged use of amphetamines. Prolonged exposure may result in organ impairment, affecting particularly the kidneys. Amphetamines are addictive and may lead to compulsive behavior, hallucinations, paranoia, and suicidal actions. Their medical use has currently been narrowed to treating only two disorders. One is a condition known as attention-deficit hyperactivity disorder (ADHD) in children. When used to treat overactive children, amphetamines are carefully administered under controlled situations as part of a larger program. The other condition for which ...

Urine drug screens have limitations, including the generation of false-positive and false-negative results. False-negative results can occur if the amphetamine screening assay has low cross-reactivity for the ingested amphetamine. For example, some amphetamine immunoassays will not detect MDMA use. For this reason, specific MDMA immunoassays are now available.. False-positive results are common in amphetamine immunoassays. Many over-the-counter (OTC) cold and cough medications interfere with amphetamine/methamphetamine screening immunoassays in urine and can trigger positive results.. Active ingredients known to interfere include ephedrine, pseudoephedrine, phentermine, and phenylephrine. In addition, the OTC drug ranitidine and the diet pill tyramine interfere with amphetamine/methamphetamine immunoassay and may trigger positive results. Finally, certain prescription drugs interfere with amphetamine/methamphetamine screening assays. These drugs include buflomedil, chloroquine, chlorpromazine, ...

Amphetamine is a CNSCentral Nervous System stimulant, producing mild euphoria and an abundance of energy. Amphetamines include both the specific chemical amphetamine and the general class of chemicals which share structural similaries. Amphetamines generally cause strong physical and mental stimulation, keeping users awake and alert for many hours, and some amphetamines cause mood lift / euphoria. Because they increase wakefulness, various amphetamines have been used by the military, by pilots, truck drivers, and other workers to keep functioning past their normal limits. Amphetamine was discovered in 1887 and exists as two enantiomers: levoamphetamine and dextroamphetamine. Amphetamine properly refers to the racemic free base, or equal parts of the enantiomers levoamphetamine and dextroamphetamine in their pure amine forms. Nonetheless, the term is frequently used informally to refer to any combination of the enantiomers, or to either of them alone. ...

An intracerebral dialysis method was used in the halothane-anaesthetized rat to further clarify the site which mediates the amphetamine-induced decrease of the striatal dopamine (DA) metabolites dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA). Following subcutaneous injection of amphetamine (0.1-5.0 mg/kg), DOPAC and HVA in striatal perfusates decreased over the 2 h time course, with 0.5 mg/kg of the drug having maximal effect. In comparison, amphetamine (0.1-5.0 mg/kg) caused a strictly dose-dependent increase of DA in striatal perfusates. Following low (0.1-5.0 mg/kg) but not high (2.0-5.0 mg/kg) doses of amphetamine there was a negative correlation between the increase of DA and decrease of DOPAC in the striatum. Amphetamine (0.5 mg/kg) caused a reduction in DA metabolism in the ibotenic acid-lesioned striatum. Intranigral injection of 10 micrograms, but not of 1 microgram amphetamine, decreased DOPAC (-27%) in the striatal perfusates. However, injection of 1 microgram amphetamine into

Amphetamine encompasses various drugs, but you will find methamphetamine is more commonly researched, talked about, and prevalent. Amphetamine is the parent drug of a family of psychostimulants, which speed up the messages going to and from the brain. Some street names for amphetamines include uppers, bennies, black beauties, and diet pills. Amphetamines usually come in powder, pills or tablets. Prescription diet pills also fall into this category of drugs. Amphetamines can be snorted, swallowed, injected, dissolved in a drink, or smoked. A common form of the drug is amphetamine sulphate, more often known as speed.. Another member of this family is methamphetamine, a more potent and more abused version of the drug. Common street names for methamphetamine are meth, speed, crank, and go. A form of methamphetamine is crystalline methamphetamine (ice or crystal meth). Because crystal meth is inexpensive to make and highly addictive, it has become a seriously dangerous drug in ...

Metabolism and Excretion Amphetamine is reported to be oxidized at the 4 position of the benzene ring to form 4-hydroxy-amphetamine, or on the side chain α or β carbons to form alpha-hydroxy-amphetamine or norephedrine, respectively. Norephedrine and 4-hydroxy-amphetamine are both active and each is subsequently oxidized to form 4-hydroxy-norephedrine. Alpha-hydroxy-amphetamine undergoes deamination to form phenylacetone, which ultimately forms benzoic acid and its glucuronide and the glycine conjugate hippuric acid. Although the enzymes involved in amphetamine metabolism have not been clearly defined, CYP2D6 is known to be involved with formation of 4-hydroxy-amphetamine. Since CYP2D6 is genetically polymorphic, population variations in amphetamine metabolism are a possibility.. Amphetamine is known to inhibit monoamine oxidase, whereas the ability of amphetamine and its metabolites to inhibit various P450 isozymes and other enzymes has not been adequately elucidated.

Amphetamines are drugs that stimulate the nervous system. They may be used in the treatment of attention deficit hyperactivity disorder (ADHD), narcolepsy (a sleeping disorder), and other conditions. Amphetamines produce increased alertness and a feeling of euphoria. Common amphetamine medicines include dextroamphetamine (Dexedrine) and methamphetamine (Desoxyn). Amphetamines can be misused and are sometimes sold illegally with names such as speed, ice, meth, and lid poppers. ...

There have been previous studies on this which have shown somewhat mixed results and findings. Some participants have said that their amphetamine use led to a more positive sexual experience, including more sexual desire, and spontaneous erections. However, some people reported negative effects of amphetamines, such as reduced libidos and having a harder time reaching orgasms. The researchers said that there could be a correlation between amphetamine use and the possible psychosocial factors that are experienced by the user. People who use illicit drugs often times have psychcosocial problems, and the drug-use related psychosocial issues could be an explanation for the sexual problems that the user experiences. Social and environmental cues, such as drug use settings can also be factors that affect the sexual response of the user.. While women too can experience some symptoms such as having a harder time reaching orgasm if they are using amphetamines, the largest group impacted by the ...

N2 - Amphetamine exposure transiently increases Ca2+/calmodulin-dependent protein kinase II (CaMKII) α expression in the nucleus accumbens (NAcc) shell and this persistently increases local GluA1 S831 phosphorylation and enhances behavioral responding to the drug. Here we assessed whether transiently interfering with CaMKII signaling using a dominant-negative CaMKIIα mutant delivered to the NAcc shell with herpes simplex viral vectors could reverse these long-lasting biochemical and behavioral effects observed following exposure to amphetamine. As expected, transient expression of CaMKIIα K42M in the NAcc shell produced a corresponding transient increase in CaMKIIα and decrease in ...

N2 - The neuronal PAS domain protein 4 (Npas4) is a transcription factor that is almost exclusively expressed in the mammalian brain. As an activity-dependent transcription factor, Npas4 regulates the transcription of discrete genes and transcriptionally controls the experience-dependent learning and memory. In this study, we explored the impact of the psychostimulant amphetamine (AMPH) on Npas4 protein expression in the rat striatum. We found that acute systemic injection of AMPH had a minimal effect on protein levels of Npas4 in the caudate putamen (CPu) and nucleus accumbens (NAc), while AMPH readily increased protein products of the immediate early gene c-Fos in these regions. In contrast, ...

The combination of dextroamphetamine and amphetamine is used as part of a total treatment program for attention deficit hyperactivity disorder (ADHD). It works in the brain to decrease the hyperactivity of patients with this disorder.. Amphetamine-dextroamphetamine is a stimulant and appetite suppressant. It stimulates the central nervous system (nerves and brain) by increasing the amount of certain chemicals in the body. This increases heart rate and blood pressure and decreases appetite, among other effects. The combination of dextroamphetamine and amphetamine comes as a tablet to take by mouth. It is usually taken once or twice daily with or without food.. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.

Marmosets were trained on a task involving simultaneous and successive visual discrimination performance where responses were required on all trials. Performance of this task was not affected by low doses of amphetamine. From this it is concluded that amphetamine does not cause a narrowing of attention and that the disruptive effect of amphetamine on the go-no go successive discrimination task already reported is due to a loss of response inhibition rather than to difficulties in the recognition of stimuli presented without a comparison stimulus.. ...

Using Microgenics unique technology, cloned enzyme donor immunoassay (CEDIA), the multiplex assay (CEDIA Amphetamines/Ecstasy) has been developed for the detection of amphetamine, methamphetamine, and ecstasy drugs at cutoff level either of 500 ng/mL or 1000 ng/mL applicable for either qualitative screening or semiquantitative measurement. The multiplex assay detects the total concentration of amphetamine, methamphetamine, and ecstasy drugs in urine samples. In addition, the assay detects metabolites of parent drugs and structurally related drugs including d,l-amphetamine (67.2%), d,l-methamphetamine (58.4%), MDA (113%), MDMA (199%), MDEA (207%), MBDB (123%), BDB (72%), PMA (24%), and PMMA (100%).

The pharmacology of novel psychoactive substances is mostly unknown. We evaluated the transporter and receptor interaction profiles of a series of para-(4)-substituted amphetamines and pyrovalerone cathinones. We tested the potency of these compounds to inhibit the norepinephrine (NE), dopamine (DA), and serotonin (5-HT) transporters (NET, DAT, and SERT, respectively) using human embryonic kidney 293 cells that express the respective human transporters. We also tested the substance-induced efflux of NE, DA, and 5-HT from monoamine-loaded cells, binding affinities to monoamine receptors, and 5-HT2B receptor activation. Para-(4)-substituted amphetamines, including 4-methylmethcathinone (mephedrone), 4-ethylmethcathinone, 4-fluoroamphetamine, 4-fluoromethamphetamine, 4-fluoromethcatinone (flephedrone), and 4-bromomethcathinone, were relatively more serotonergic (lower DAT:SERT ratio) compared with their analogs amphetamine, methamphetamine, and methcathinone.

An international scheme to produce and distribute amphetamine was stopped by a joined intervention of Swedish and Czech police, leading to a shutdown of the largest drug laboratory ever found in this part of the world. The lab was located in the Bohemia region and it allegedly served entire Sweden over the period of the last five years, with the total produced in this timeframe estimated at 3.5 tons and a capacity to churn out multi-kilo quantities in a single cycle. Seven people were arrested in relation to the case - four in the Czech Republic and another 3 in Sweden. 700 liters of chemicals used for amphetamine synthesis was discovered at the site, along with 600 liters of waste, while cash, cars and other assets likely acquired through drug trade were confiscated... A Swedish man well-known to the police for his drug activity in the past was supposedly financing the ring, while others arranged for production and transportation of amphetamine into Sweden, where it was predominantly sold. ...

and a methyl group adjacent to the phenyl. A large number of chemicals fall into this category, including the club drug MDMA (Ecstasy) and methamphetamine. It is because of the close association with methamphetamine that amphetamine is mistakenly thought of as speed. It is important to note that such an amphetamine class does not technically exist. Phamacodynamically, these drugs all fall under the umbrella of central nervous system stimulants; chemically, they are phenylethylamines. Amphetamine, for example, is methylated phenylethylamine, and methamphetamine is double methylated phenylethylamine.. Amphetamine traditionally comes in the salt-form amphetamine sulphate and is comprised of 50% l- and 50% d-amphetamine (where l- and d- refer to levo and dextro, the two optical orientations the amphetamine structure can have). In the United States, pharmaceutical products containing solely amphetamine (for example, Biphetamine) are no longer manufactured. Today, dextroamphetamine (d-amphetamine) ...

Animals and drug treatment protocol. All experimental procedures were performed in accordance with the United States Public Health Service publication Guide for the Care and Use of Laboratory Animals and were approved by the Institutional Animal Care and Use Committee at the University of Pittsburgh. A total of 144 male Sprague Dawley rats, consisting of 72 vehicle-treated control rats and 72 rats treated with amphetamine, were used in this study. The control rats were treated with 0.9% saline and were subjected to treatment withdrawal in parallel with each group of the amphetamine-treated rats. One set of rats (n = 42) weighing 150-175 gm at the start of treatment were given daily injections of amphetamine (1-3 mg/kg, i.p.) in their home cages for 2-4 weeks. This dosing protocol has been reported to elicit sensitization with respect to stimulant-evoked locomotor behavior in rats (Robinson and Becker, 1986; Kalivas and Duffy, 1990; Wolf et al., 1994; 1995). A second set of rats (n = 30) were ...

Amphetamines are a class of central nervous system stimulants with a similar chemical structure, including amphetamine, methamphetamine, dextroamphetamine, ephedrine, and others. Generally, these drugs generate emotional, cognitive, and physical effects, such as increased energy and focus and decreased appetite. They may be prescribed legally for the treatment of ADHD, narcolepsy, or other conditions; they are also used illegally to improve performance, lose weight, or to generate a

Although methamphetamine (MA) and other amphetamines can have similar effects, differences also exist. For example, MA has longer lasting and more toxic effects than amphetamine.[1] This is largely because the N-methyl group that differentiates MA from amphetamine decreases the polarity of the molecule, enabling it to better penetrate the blood brain barrier.[2]. In addition, compared with amphetamine, MA has greater activity as a central nervous system (CNS) stimulant while having less peripheral nervous system and cardiovascular stimulation activity. Another difference between amphetamine and MA is that amphetamine stimulates the CNS indirectly by activating the release of catecholamines and inhibiting their breakdown and storage. In contrast, MA stimulates the postsynaptic catecholamine receptors directly.[2] ...

1. These experiments examined the effects of a high NaCl diet on (Na+, K+)-ATPase in kidney, heart and cerebral cortex, on the level of circulating inhibitor of (Na+, K+)-ATPase in plasma, and on stimulation of (Na+, K+)-ATPase by treatment with dextro (d)-amphetamine.. 2. High salt diet increased indices of (Na+, K+)-ATPase activity (K+-activated p-nitrophenylphosphatase activity and ouabain binding) in kidney medulla, prevented stimulation by amphetamine in cerebral cortex and reduced amphetamine stimulation in heart.. 3. High NaCl feeding increased the plasma level of circulating inhibitor of (Na+, K+)-ATPase.. 4. Amphetamine alone had no effect on inhibitor level but amphetamine administration reduced the increase in inhibitor with high NaCl feeding.. ...

They said their new study adds to evidence about the need to tackle the global stimulant epidemic.. The investigators were led by Stuart Reece, a clinical associate professor at the University of Western Australia. They assessed arterial stiffening in more than 700 Australians in their 30s and 40s. Arteries tend to harden with age.. Those participants who used illegal amphetamines showed greater aging of the arteries than others, including those who smoked tobacco or used the heroin substitute methadone, the study reported.. The link between illegal amphetamine use and greater aging of the arteries was seen in men and women. It was also independent of other risk factors for heart disease and stroke, Reece and his colleagues said.. ...
