A class of chemicals derived from barbituric acid or thiobarbituric acid. Many of these are GABA MODULATORS used as HYPNOTICS AND SEDATIVES, as ANESTHETICS, or as ANTICONVULSANTS.
A barbiturate that is used as a sedative. Secobarbital is reported to have no anti-anxiety activity.
A short-acting barbiturate that is effective as a sedative and hypnotic (but not as an anti-anxiety) agent and is usually given orally. It is prescribed more frequently for sleep induction than for sedation but, like similar agents, may lose its effectiveness by the second week of continued administration. (From AMA Drug Evaluations Annual, 1994, p236)
A barbiturate with hypnotic and sedative properties (but not antianxiety). Adverse effects are mainly a consequence of dose-related CNS depression and the risk of dependence with continued use is high. (From Martindale, The Extra Pharmacopoeia, 30th ed, p565)
A barbiturate that is administered intravenously for the induction of general anesthesia or for the production of complete anesthesia of short duration.
A long-acting barbiturate that depresses most metabolic processes at high doses. It is used as a hypnotic and sedative and may induce dependence. Barbital is also used in veterinary practice for central nervous system depression.
An intravenous anesthetic with a short duration of action that may be used for induction of anesthesia.
A barbituric acid derivative that acts as a nonselective central nervous system depressant. It potentiates GAMMA-AMINOBUTYRIC ACID action on GABA-A RECEPTORS, and modulates chloride currents through receptor channels. It also inhibits glutamate induced depolarizations.
A barbiturate that is metabolized to PHENOBARBITAL. It has been used for similar purposes, especially in EPILEPSY, but there is no evidence mephobarbital offers any advantage over PHENOBARBITAL.
Substances that do not act as agonists or antagonists but do affect the GAMMA-AMINOBUTYRIC ACID receptor-ionophore complex. GABA-A receptors (RECEPTORS, GABA-A) appear to have at least three allosteric sites at which modulators act: a site at which BENZODIAZEPINES act by increasing the opening frequency of GAMMA-AMINOBUTYRIC ACID-activated chloride channels; a site at which BARBITURATES act to prolong the duration of channel opening; and a site at which some steroids may act. GENERAL ANESTHETICS probably act at least partly by potentiating GABAergic responses, but they are not included here.
Drugs used to induce drowsiness or sleep or to reduce psychological excitement or anxiety.
A barbiturate that is effective as a hypnotic and sedative.
Cell surface proteins which bind GAMMA-AMINOBUTYRIC ACID and contain an integral membrane chloride channel. Each receptor is assembled as a pentamer from a pool of at least 19 different possible subunits. The receptors belong to a superfamily that share a common CYSTEINE loop.
A barbiturate that is administered intravenously for the production of complete anesthesia of short duration, for the induction of general anesthesia, or for inducing a hypnotic state. (From Martindale, The Extra Pharmacopoeia, 30th ed, p919)
Process of preserving a dead body to protect it from decay.
A quinazoline derivative with hypnotic and sedative properties. It has been withdrawn from the market in many countries because of problems with abuse. (From Martindale, The Extra Pharmacopoeia, 30th ed, p604)
An antiepileptic agent related to the barbiturates; it is partly metabolized to PHENOBARBITAL in the body and owes some of its actions to this metabolite. Adverse effects are reported to be more frequent than with PHENOBARBITAL. (From Martindale, The Extra Pharmacopoeia, 30th ed, p309)
The air-dried exudate from the unripe seed capsule of the opium poppy, Papaver somniferum, or its variant, P. album. It contains a number of alkaloids, but only a few - MORPHINE; CODEINE; and PAPAVERINE - have clinical significance. Opium has been used as an analgesic, antitussive, antidiarrheal, and antispasmodic.
A hypnotic and sedative. Its use has been largely superseded by other drugs.
A group of two-ring heterocyclic compounds consisting of a benzene ring fused to a diazepine ring.
Agents that are capable of inducing a total or partial loss of sensation, especially tactile sensation and pain. They may act to induce general ANESTHESIA, in which an unconscious state is achieved, or may act locally to induce numbness or lack of sensation at a targeted site.
A carbamate with hypnotic, sedative, and some muscle relaxant properties, although in therapeutic doses reduction of anxiety rather than a direct effect may be responsible for muscle relaxation. Meprobamate has been reported to have anticonvulsant actions against petit mal seizures, but not against grand mal seizures (which may be exacerbated). It is used in the treatment of ANXIETY DISORDERS, and also for the short-term management of INSOMNIA but has largely been superseded by the BENZODIAZEPINES. (From Martindale, The Extra Pharmacopoeia, 30th ed, p603)
Formerly a constituent republic of Yugoslavia, comprising the Yugoslav section of the region of Macedonia. It was made a constituent republic in the 1946 constitution. It became independent on 8 February 1994 and was recognized as The Former Yugoslav Republic of Macedonia by the United States Board on Geographic Names 16 February 1994.
A benzodiazepine derivative used mainly as a hypnotic.
A noncompetitive antagonist at GABA-A receptors and thus a convulsant. Picrotoxin blocks the GAMMA-AMINOBUTYRIC ACID-activated chloride ionophore. Although it is most often used as a research tool, it has been used as a CNS stimulant and an antidote in poisoning by CNS depressants, especially the barbiturates.
A benzodiazepine with anticonvulsant, anxiolytic, sedative, muscle relaxant, and amnesic properties and a long duration of action. Its actions are mediated by enhancement of GAMMA-AMINOBUTYRIC ACID activity.
An anticonvulsant that is used to treat a wide variety of seizures. It is also an anti-arrhythmic and a muscle relaxant. The mechanism of therapeutic action is not clear, although several cellular actions have been described including effects on ion channels, active transport, and general membrane stabilization. The mechanism of its muscle relaxant effect appears to involve a reduction in the sensitivity of muscle spindles to stretch. Phenytoin has been proposed for several other therapeutic uses, but its use has been limited by its many adverse effects and interactions with other drugs.
A sedative and anticonvulsant often used in the treatment of alcohol withdrawal. Chlormethiazole has also been proposed as a neuroprotective agent. The mechanism of its therapeutic activity is not entirely clear, but it does potentiate GAMMA-AMINOBUTYRIC ACID receptors response and it may also affect glycine receptors.
Fluoroimmunoassay where detection of the hapten-antibody reaction is based on measurement of the increased polarization of fluorescence-labeled hapten when it is combined with antibody. The assay is very useful for the measurement of small haptenic antigens such as drugs at low concentrations.

Significance of acute cerebral swelling in patients with sylvian hematoma due to ruptured middle cerebral artery aneurysm, and its management. (1/447)

A retrospective study of 75 patients treated surgically for ruptured middle cerebral artery (MCA) aneurysm within 48 hours evaluated clinical grade at admission, secondary development and management of cerebral swelling associated with space-occupying hematoma, cerebral infarction caused by vasospasm, development of hydrocephalus, and clinical outcome. Clinical grade at admission was significantly better in patients without than in those with hematoma (p < 0.01). Twenty-seven patients with sylvian hematoma caused by ruptured MCA aneurysm often developed ipsilateral cerebral swelling in the early period after subarachnoid hemorrhage. Seventeen of these patients developed serious cerebral swelling and received barbiturate therapy. Nine of these 17 patients had good outcome, but six patients died of cerebral swelling. The incidence of hydrocephalus was significantly higher in patients with than in those without hematoma (p < 0.01). The incidence of infarction was more pronounced in patients with sylvian hematoma. Clinical outcome was significantly better in patients without than in those with sylvian hematoma (p < 0.01). Development of cerebral swelling in patients with sylvian hematoma due to ruptured MCA aneurysm has a significant effect on outcome, and improvements in management are required.  (+info)

Surgical treatment of internal carotid artery anterior wall aneurysm with extravasation during angiography--case report. (2/447)

A 54-year-old female presented subarachnoid hemorrhage from an aneurysm arising from the anterior (dorsal) wall of the internal carotid artery (ICA). During four-vessel angiography, an extravasated saccular pooling of contrast medium emerged in the suprasellar area unrelated to any arterial branch. The saccular pooling was visualized in the arterial phase and cleared in the venophase during every contrast medium injection. We suspected that the extravasated pooling was surrounded by hard clot but communicated with the artery. Direct surgery was performed but major premature bleeding occurred during the microsurgical procedure. After temporary clipping, an opening of the anterior (dorsal) wall of the ICA was found without apparent aneurysm wall. The vessel wall was sutured with nylon thread. The total occlusion time of the ICA was about 50 minutes. Follow-up angiography demonstrated good patency of the ICA. About 2 years after the operation, the patient was able to walk with a stick and to communicate freely through speech, although left hemiparesis and left homonymous hemianopsia persisted. The outcome suggests our treatment strategy was not optimal, but suture of the ICA wall is one of the therapeutic choices when premature rupture occurs in the operation.  (+info)

Antifungal susceptibility testing of Candida species by flow cytometry. (3/447)

The feasibility of flow cytometric antifungal susceptibility testing has been studied using the fluorescent anionic membrane potential probe, bis-(1,3-dibutylbarbituric acid) trimethine oxonol [DiBAC4(3)]. The in vitro antifungal susceptibility testing of amphotericin B was performed on 8 Candida isolates from clinical specimens and 2 ATCC strains by flow cytometry with the results compared to those of the National Committee of Clinical Laboratory Standards (NCCLS) M27-T, broth macrodilution method. The flow cytometric method is based on an increase of fluorescence given out by DiBAC4(3) in fungi when they are killed by antifungal agents. Minimum inhibitory concentration (MIC) of amphotericin B ranged from 0.25 to 1 microg/mL. All results agreed within +/-2 dilution between the flow cytometric method and the M27-T method. MIC with ATCC strains were within recommended ranges of M27-T. The new flow cytometric method revealed a clear and distinct reproducible test end point. A four hr of incubation was sufficient for the test. In conclusion, flow cytometry using DiBAC4(3) is a rapid and accurate in vitro antifungal susceptibility testing method.  (+info)

Long-term potentiation in the dentate gyrus is not linked to increased extracellular glutamate concentration. (4/447)

Long-term potentiation (LTP) of excitatory transmission is a likely candidate for the encoding and storage of information in the mammalian brain. There is a general agreement that LTP involves an increase in synaptic strength, but the mechanisms underlying this persistent change are unclear and controversial. Synaptic efficacy may be enhanced because more transmitter glutamate is released or because postsynaptic responsiveness increases or both. The purpose of this study was to examine whether increased extracellular glutamate concentration was associated with the robust and well-characterized LTP that can be induced in the rat dentate gyrus. To favor the detection of any putative change in extracellular glutamate associated with LTP, our experimental strategy included the following features. 1) Two separate series of experiments were carried out with animals under pentobarbital or urethan anesthesia; 2) changes in extracellular concentration of glutamate were monitored continuously by microdialysis coupled to enzyme amperometry; and 3) dialysate glutamate levels and changes in the slope of excitatory postsynaptic potential evoked by activation of the perforant path were recorded precisely at the same site. Tetanic stimulation of the perforant path increased persistently test-evoked responses in the dentate gyrus (by 19 and 14% in barbiturate and urethan group, respectively), but there was no glutamate change either during or after LTP induction and no indication of increased glutamate efflux when low-frequency stimulation was applied. The results do not rule out a possible contribution of enhanced glutamate exocytosis to LTP induction and/or maintenance because such a presynaptic change may not be detectable extracellularly. However, our findings and other data supporting the notion that neurotransmitter glutamate may hardly leak out of the synaptic cleft conflict with the hypothesis that LTP could also involve a broad synaptic spillover of glutamate.  (+info)

Assessment of the effect of amphotericin B on the vitality of Candida albicans. (5/447)

The processes involved in cell death are complex, and individual techniques measure specific fractions of the total population. The interaction of Candida albicans with amphotericin B was measured with fluorescent probes with different cellular affinities. These were used to provide qualitative and quantitative information of physiological parameters which contribute to fungal cell viability. SYBR Green I and 5,(6)-carboxyfluorescein were used to assess membrane integrity, and bis-(1,3-dibutylbarbituric acid)trimethine oxonol and 3,3-dihexyloxacarbocyanine iodide were used to evaluate alterations in membrane potential. The fluorescent indicators were compared with replication competency, the conventional indicator of viability. By using these tools, the evaluation of the response of C. albicans to amphotericin B time-kill curves delineated four categories which may represent a continuum between alive and dead. The data showed that replication competency (CFU per milliliter) as determined by conventional antifungal susceptibility techniques provided only an estimate of inhibition. Interpretation of fluorescent staining characteristics indicated that C. albicans cells which were replication incompetent after exposure to greater than 0.5 microgram of amphotericin B per ml still maintained degrees of physiological function.  (+info)

Comparison of fungal laccases and redox mediators in oxidation of a nonphenolic lignin model compound. (6/447)

Several fungal laccases have been compared for the oxidation of a nonphenolic lignin dimer, 1-(3, 4-dimethoxyphenyl)-2-(2-methoxyphenoxy)propan-1,3-diol (I), and a phenolic lignin model compound, phenol red, in the presence of the redox mediators 1-hydroxybenzotriazole (1-HBT) or violuric acid. The oxidation rates of dimer I by the laccases were in the following order: Trametes villosa laccase (TvL) > Pycnoporus cinnabarinus laccase (PcL) > Botrytis cinerea laccase (BcL) > Myceliophthora thermophila laccase (MtL) in the presence of either 1-HBT or violuric acid. The order is the same if the laccases are used at the same molar concentration or added to the same activity (with ABTS [2, 2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid)] as a substrate). During the oxidation of dimer I, both 1-HBT and violuric acid were to some extent consumed. Their consumption rates also follow the above order of laccases, i.e., TvL > PcL > BcL > MtL. Violuric acid allowed TvL and PcL to oxidize dimer I much faster than 1-HBT, while BcL and violuric acid oxidized dimer I more slowly than BcL and 1-HBT. The oxidation rate of dimer I is dependent upon both kcat and the stability of the laccase. Both 1-HBT and violuric acid inactivated the laccases, violuric acid to a greater extent than 1-HBT. The presence of dimer I or phenol red in the reaction mixture slowed down this inactivation. The inactivation is mainly due to the reaction of the redox mediator free radical with the laccases. We did not find any relationship between the carbohydrate content of the laccases and their inactivation. When the redox potential of the laccases is in the range of 750 to 800 mV, i.e., above that of the redox mediator, it does not affect kcat and the oxidation rate of dimer I.  (+info)

Pharmacological evidence for a KATP channel in renin-secreting cells from rat kidney. (7/447)

1. Openers of the ATP-sensitive potassium channel (KATP channel) increase and blockers decrease renin secretion. Here we report the effects of levcromakalim (LCRK, a channel opener) and glibenclamide (GBC, a blocker) on membrane potential, whole-cell current and the cytoplasmic Ca2+ concentration of renin-secreting cells (RSC). Studies were performed on afferent arterioles from the kidney of Na+-depleted rats. 2. As monitored with the fluorescent oxonol dye DiBAC4(3), LCRK (0.3 and 1 microM) induced a hyperpolarization of approximately 15 mV which was abolished by GBC (1 microM). 3. Whole-cell current-clamp experiments showed that RSC had a membrane potential of -61 +/- 1 mV (n = 16). LCRK (1 microM) induced a hyperpolarization of 9.9 +/- 0.2 mV (n = 16) which, in the majority of cells, decreased slowly with time. 4. Capacitance measurements showed a strong electrical coupling of the cells in the preparation. 5. At -60 mV, LCRK induced a hyperpolarizing current in a concentration-dependent manner with an EC50 of 152 +/- 31 nM and a maximum current of about 200 pA. 6. Application of GBC (1 microM) produced no effect; however, when applied after LCRK (300 nM), GBC inhibited the opener-induced hyperpolarizing current with an IC50 of 103 +/- 36 nM. 7. LCRK (0.3 and 1 microM) did not significantly affect the cytoplasmic Ca2+ concentration either at rest or after stimulation by angiotensin II. 8. The data show that LCRK induces a GBC-sensitive hyperpolarizing current in rat RSC. This current presumably originates from the activation of KATP channels which pharmacologically resemble those in vascular smooth muscle cells. The stimulatory effect of KATP channel opening on renin secretion is not mediated by a decrease in intracellular Ca2+ concentration.  (+info)

Preparation of barbiturate optical isomers and their effects on GABA(A) receptors. (8/447)

BACKGROUND: Barbiturate anesthetics are optically active and usually exist in two mirror-image enantiomeric forms. Their stereoselective effects in mammals are well known, but remarkably few data are available concerning their effects on anesthetic targets in vitro. This is in part because of the lack of availability of pure barbiturate enantiomers. Such in vitro data could be used to test the relevance of putative molecular targets. METHODS: A high-performance liquid chromatography technique using a permethylated beta-cyclodextrin column was used to separate the optical isomers of three barbiturates in preparative quantities. The effects of the isomers on GABA-induced currents in stably transfected mouse fibroblast cells were investigated using the whole-cell patch-clamp technique. RESULTS: Highly purified optical isomers of hexobarbital, pentobarbital, and thiopental were prepared, and their effects were studied on a gamma-aminobutyric acid type A receptor of defined subunit composition. For each of the three barbiturates, both enantiomers potentiated gamma-aminobutyric acid-induced currents at pharmacologically relevant concentrations, with the S-enantiomer being more potent than the R-enantiomer by a factor of between 1.7 and 3.5. The degree of stereoselectivity did not vary greatly with anesthetic concentration. CONCLUSIONS: The rank order and degree of stereoselectivity that we have observed for the enantiomers of hexobarbital, pentobarbital, and thiopental acting on the gamma-aminobutyric acid type A receptor are entirely consistent with this receptor playing a central role in the anesthetic actions of barbiturates.  (+info)

The central nervous system effects of a convulsant barbiturate, sodium 5-ethyl-5-(1,3-dimethylbutyl) barbiturate, were compared with the actions of pentobarbital in cats. Depending upon the dose, the convulsant barbiturate has both stimulant and depressant properties.. Under special conditions the convulsant barbiturate was shown to increase the mean convulsant dose of a timed intravenous infusion of pentylenetetrazole. Comparable amounts of pentobarbital were much more effective in increasing the mean convulsant dose of pentylenetetrazole. The depressant actions of the convulsant barbiturate appear to be real and not secondary to the stimulant effects.. The low to medium-voltage, medium to fast-frequency pattern observed in the EEG with the convulsant barbiturate was still present in three of five mesencephalic preparations verified by autopsy to be complete transections. In the remaining two preparations the convulsant barbiturate reduced the frequency of spindle bursts and prolonged the ...
Barbiturate dependence develops with regular use of barbiturates. This in turn may lead to a need for increasing doses of the drug to get the original desired pharmacological or therapeutic effect.[1] Barbiturate use can lead to both addiction and physical dependence, and as such they have a high potential for abuse[2], however, it does not affect all users. Management of barbiturate dependence involves considering the affected persons age, comorbidity and the pharmacological pathways of barbiturates.[3] Psychological addiction to barbiturates can develop quickly. The patients will then have a strong desire to take any barbiturate-like drug. The chronic abuse of barbiturates leads to moderate degradation of the personality with narrowing of interests, passivity and loss of volition. The somatic signs include hypomimia, problems articulating, weakening of reflexes and ataxia.[4] The GABAA receptor, one of barbiturates main sites of action, is thought to play a pivotal role in the development of ...

Barbiturates (except for the less-soluble phenobarbital) are mainly metabolized by the liver into inactive, water-soluble compounds by oxidation and then are renally excreted or conjugated to glucuronic acid and excreted in bile. The most significant aspect of the metabolism of barbiturates (e.g., phenobarbital, thiopental, methohexital) is their effect on the hepatic microsomal enzyme system (cytochrome P450 (CYP) enzymes). These effects are dependent on the duration of exposure to the barbiturate. Acutely, barbiturates interact with various CYPs and inhibit the biotransformation of other CYP substrates; likewise, other substrates (e.g., other drugs or endogenous substrates) can inhibit the barbiturate metabolism. Chronic use of barbiturates will cause upregulation, or induction, of the microsomal enzymes (CYPs 1A2, 2C9, 2C19, and 3A4), increasing the metabolism of drugs metabolized by these enzymes. This can lead to patients requiring larger dosages of medication to achieve therapeutic effect ...

TY - JOUR. T1 - Self-administration of barbiturates and benzodiazepines. T2 - A review. AU - Ator, Nancy A.. AU - Griffiths, Roland R.. PY - 1987/6. Y1 - 1987/6. N2 - Studies of barbiturate and benzodiazepine self-administration are categorized by species and route of administration. Reinforcement, defined as self-administration of drug greater than of a non-drug control, has been demonstrated most often in studies employing the IV route, and there has been greater reliability in this result for a given drug among barbiturates rather than among benzodiazepines. Most studies of PO self-administration in rodents have not demonstrated reinforcement, despite a number of behavioral manipulations to induce drug intake. Studies of PO barbiturate self-administration in monkeys have demonstrated reinforcement but recent studies of PO benzodiazepine self-administration in baboons have not, although physical dependence was demonstrated. Reinforcement via the IG route has not been reliably demonstrated. ...
Barbiturate overdose is poisoning due to excessive doses of barbiturates. Symptoms typically include difficulty thinking, poor coordination, decreased level of consciousness, and a decreased effort to breathe (respiratory depression). Complications of overdose can include noncardiogenic pulmonary edema. If death occurs this is typically due to a lack of breathing. Barbiturate overdose may occur by accident or purposefully in an attempt to cause death. The toxic effects are additive to those of alcohol and benzodiazepines. The lethal dose varies with a persons tolerance and how the drug is taken. The effects of barbiturates occur via the GABA neurotransmitter. Exposure may be verified by testing the urine or blood. Treatment involves supporting a persons breathing and blood pressure. While there is no antidote, activated charcoal may be useful. Multiple doses of charcoal may be required. Hemodialysis may occasionally be considered. Urine alkalinisation has not been found to be useful. While ...
Derivatives of barbituric acid have diminished in popularity as drugs over the years. Are there really no new indications for these compounds?
Three patients who presented with grand real seizures and an associated behavioral disorder were recognized as suffering from a severe butalbital withdrawal syndrome. All were migraineurs who had become dependent on barbiturates. We propose that the occurrence of seizures, psychotic behavior, or a recent personality change should be considered clues to possible barbiturate abuse in patients with migraine. ...
Butalbital can cause dependence and/or addiction. Mixing with alcohol increases the risk of intoxication, increases respiratory depression, and increases liver toxicity when the butalbital is in combination with paracetamol (acetaminophen). Many opioid-dependent persons frequently use barbiturates as a potentiator to their normal dose of opiates in order to increase the effects, or with a less than normal dose as means of conserving their supply.[citation needed] Especially when used with the stronger narcotics, suicide or accidental death occurs much more frequently than first reported with one drug alone. Use of alcohol, benzodiazepines, and other CNS-depressants often also contribute to respiratory depression, coma, and in extreme cases fatality. When benzodiazepines are co-administered with barbiturates, the sum effect of the drugs is far greater than would be expected considering the effect of both drugs separately. This is due to complementary mechanisms at the GABAA receptor, where ...
55. Tolerance to some of the effects of barbiturates can be demonstrated, although the degree and rate of tolerance acquisition varies considerably with the dose, frequency of administration and the individual. The potential for tolerance is much lower with barbiturates than with the opiate narcotics, and appears to level off at a maximum of 1.0 - 2.5gm. per day. (A normal sleep-inducing dose might be around 0.1 - 0.3gm.) While this loss of drug sensitivity is quite general and applies to both sedative and mood effects, no tolerance appears to develop to the lethal toxicity level since chronic users are as susceptible to fatal over-doses as are initiates. In other words, the safety margin decreases with increased tolerance. Several mechanisms operate in producing tolerance. Barbiturates stimulate the bodys production of the metabolic enzymes which inactivate the drug. Also, some insensitivity to the depressant effects appears which might reflect a general neurological adaptation. Certain ...
The answer is C. The mechanisms by which barbiturates produce unconsciousness have been extensively researched. Barbiturates exert their effect at the GABAA receptor, but appear to have a concentration-dependent effect. At low concentrations, barbiturates bind to the receptor, preventing the dissociation of GABA from the receptor and thereby prolonging its effect; at higher concentrations, there appears to be a direct activation of the chloride channels, mimicking GABA without requiring its binding to the receptor. Either mechanism increases the flow of chloride through the central pore of the receptor. This hyperpolarizes the postsynaptic cell membrane and results in inhibition of postsynaptic neuron. ...
Barbiturates are central nervous system depressants and they act in a similar manner to alcohol and slow down many areas of the brain. This application note presents a method of extracting barbiturates from urine and plasma samples by using Tox-Elut solid phase extraction columns and identification through UV/Vis absorbance spectrum comparisons with a reference library.
Barbiturates are a class of antidepressants whose abuse and addiction by recreational users has become a widespread problem (www.nlm.nih.gov). In our work we strived to streamline the barbiturate screening process to provide a fast, cost-effective, and reproducible method from start to finish for forensic labs who are involved in high-throughput processing.
Barbiturates are a group of drugs in the class of drugs known as sedative-hypnotics, which generally describes their sleep-inducing and anxiety-decreasing effects. Read about symptoms, treatment, effects, and statistics.

The butalbital and the codeine in this medicine will add to the effects of alcohol and other central nervous system (CNS) depressants (medicines that slow down the nervous system, possibly causing drowsiness). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; other prescription pain medicine or narcotics; other barbiturates; medicine for seizures; muscle relaxants; or anesthetics, including some dental anesthetics. Also, stomach problems may be more likely to occur if you drink alcoholic beverages while you are taking aspirin. Therefore, do not drink alcoholic beverages, and check with your doctor before taking any of the medicines listed above, while you are using this medicine.. This medicine may cause some people to become drowsy, dizzy, or lightheaded, or to feel a false sense of well-being. Make sure you know how you react to this medicine before you drive, use machines, or do anything ...
Briefly, we should also mention that barbiturates are effective in reducing ICP refractory to other measures, although they should not be used in the presence of hypotension or hypovolemia. Furthermore, barbiturates often cause hypotension, so they are not indicated in the acute resuscitative phase. The hypotension can lead to the use of vasopressors. In turn, the increase in systemic vascular resistance caused by the use of vasopressors may lead to end organ hypoperfusion and significant metabolic acidosis which can in turn worsen the hypotension. This leads to a vicious cycle. The long half-life of most barbiturates prolongs the time for determining brain death, which is a consideration in patients with devastating and likely nonsurvivable injury. Barbiturates are not recommended to induce burst suppression measured by EEG to prevent the development of intracranial hypertension. Sometimes, a rapid bolus of IV pentobarbital is administered but drips are generally not recommended. ATLS states, ...
With disease issues, the decline of the rendering industry, a ban on use of downer cows for food, and rules to halt horse slaughter, environmentally safe and sound practices for disposal of horses and other livestock mortalities are limited. Improper disposal of carcasses containing veterinary drugs has resulted in the death of domestic animals and wildlife. Composting of carcasses has been performed successfully to reduce pathogens, nutrient release, and biosecurity risks. However, there is concern that drugs used in the livestock industry, as feed additives and veterinary therapies do not degrade readily and will persist in compost or leachate, threatening environmental exposure to wildlife, domestic animals and humans. Two classes of drugs commonly used in the livestock and horse industries include barbiturates for euthanasia and non-steroidal anti-inflammatory drugs (NSAID) for relief of pain and inflammation. Sodium pentobarbital (a barbiturate) and phenylbutazone (an NSAID) concentrations ...

In 1864 von Baeyer synthesized the first barbiturate, barbituric acid. The first hypnotic barbiturate, diethylbarbituric acid, was synthesized by Fischer and Mering in 1903. A number of other hypnotic-sedative barbiturates were developed and tested, but all had too slow onset and too long duration of action. In 1932 Weese and Schapff synthesized the first rapid onset, short duration barbiturate, the methylated oxybarbiturate hexobarbital. Unfortunately, hexobarbital caused undesirable excitatory side effects. Thiopental was first administered by Waters (Wisconsin) and Lundy (Mayo Clinic) in 1934. Thiopental proved to be fast and brief acting and devoid of excitatory side effects. When hexobarbital and thiopental were used to anesthetize the wounded at Pearl Harbor in 1941, there were so many deaths that intravenous anesthesia with these agents was later described as an ideal method of euthanasia. (probably Halford FJ, 1943) A responding anonymous editorial correctly suggested that the cause of ...

Background: An efficient, promoted tri-component catalytic reaction between barbituric acid (or N,N-dimethyl barbituric acid), 4-hydroxy coumarin, and a wide range of aryl aldehydes using zinc oxide nanowires (ZnO NWs) to obtain some new 4-hydroxychromenylarylmethyl-6-hydroxypyrimidine-2,4-diones is described. Method: The reactants were successfully condensed via three C-C bond formation by zinc oxide nanowires (ZnO NWs) as an efficient, environmentally safe and recyclable nano catalyst to produce target molecules. In addition, the biological effects of synthesized products by the use of DPPH and acyclovir as positive controls and also Hep-2, vero cell, HSV-1, and adenovirus as four applied cell lines have been evaluated. Results: The results showed that synthesized products have anti-oxidant, cytotoxic and anti-viral activities and can offer promising prospect as biologically active agents. Conclusion: This achievement in an efficient and eco-friendly synthesis of novel analogous of hybrid molecules
I feel like legitimate, pharmaceutical Barbiturates have some how become the red-haired stepchild of modern medicine. To answer your question, YES...they are still prescribed, more than theyre talked about. My mother has taken LUMINAL (phenobarbital) for 30 years for Epilepsy, and I have taken it for 5 years for Epilepsy control. Keep in mind this is after all other treatments failed and I had two incidents of Status Epilepticus and nearly died both times. After that my Neurologists quit playing around and went to what they knew would work - Barbiturate Therapy. The only downside is that it is lifelong once started. I also take SECONAL SODIUM (secobarbital) as needed when I feel a seizure coming on (this medication is extremely rare and must be special ordered). This works well because it acts quickly and is not long lasting. For some patients traditional Anticonvulsants simply dont work...they need something stronger...they medically need Barbiturates. Obviously taking these makes you very ...

Y1 - 1999/10. N2 - Bullfrogs (Rana catesbeiana) anesthetized with a large dose of thiopental (42.8 mg/kg) retained movement responses to nociceptor stimuli despite an average plasma drug level of 51 mg/l, of which 63% was bound to plasma proteins. This concentration, when corrected to include only unbound and uncharged drug, was 2-fold greater than those reported to abolish nociceptor response (NR) during surgical anesthesia in man. The median anesthetic dose (AD50) for loss of the righting reflex was 11.2 mg/kg by s.c. injection into the abdominal lymph sac; however, at 54.0 mg/kg, all frogs retained NRs, although otherwise deeply anesthetized. The ratio of NR-blocking dose to light AD was thus ,4.8, as compared to AB - Bullfrogs (Rana catesbeiana) anesthetized with a large dose of thiopental (42.8 ...

SECOS : Secobarbital is a short-acting barbiturate with hypnotic properties used as a preanesthetic agent and in the short-term treatment of insomnia.(1,2)   Secobarbital is administered orally. The duration of its hypnotic effect is about 3 to 4 hours. The drug distributes throughout the body, with a volume of distribution (Vd) of 1.6 to 1.9 L/kg, and about 46% to 70% of a dose is bound to plasma proteins. Metabolism takes place in the liver primarily via hepatic microsomal enzymes. Secobarbitals half-life is about 15 to 40 hours (mean: 28 hours).(2,3)

Sedative-hypnotics are drugs which depress or slow down the bodys functions. Often these drugs are referred to as tranquilizers and sleeping pills or sometimes just as sedatives. Their effects range from reducing anxiety to promoting sleep.. Both tranquilizers and sleeping pills can have either effect, depending on how much is taken. Some are also used to induce anesthesia for short surgical procedures. At high doses or when they are abused, many of these drugs can lead to dependency or cause unconsciousness and death.. Barbiturates and benzodiazepines are two major categories of sedative-hypnotics.. Barbiturates are powerful depressants that slow down the central nervous system. They include Amytal, Nembutal, phenobarbital, Seconal, Tuinal. This drug category has largely been replaced by the newer, safer benzodiazepines. Common benzodiazepines include Xanaz, Valium and Librium.. How can you tell if a friend is using?. At low doses:. ...
GABA (Gamma-aminobutyric acid) was the first new transmitter to be discovered after the three classic transmitters (norepinephrine, acetylcholine, and serotonin). It is one of the most frequently occurring transmitters in the central nervous system. Generally it has an inhibitory function. Sedative-hypnotic drugs like barbiturates act by stimulating release of GABA-like substances.. What is the usual effect of GABA?. Valium and the class of tranquilizers it represents, benzodiazepines, also act on the GABA-related transmitter systems. The benzodiazepines and the barbiturates are quite different in their structure, clinical effects, and mode of action...but they both act to reduce anxiety, and they both do it by boosting levels of GABA..

Today, γ-aminobutyric acid (GABA) is recognized as the most important inhibitory neurotransmitter in the mammalian CNS comprising 40% of inhibitory synaptic processing. As its receptor GABAA is largely responsible for effects of alcohol, it can be argued that it is one of the oldest drug targets known.. In the 1870s, chloral hydrate, whose metabolite modulates the GABA receptor complex, was widely used as a sedative and as a treatment for insomnia. Although effective, abuse and dependence were major issues and by the 1920s its use had been almost entirely supplanted by the barbiturates which work on the GABAA receptor.. Unfortunately, it soon became apparent that barbiturates also carry the risk of abuse, dependence, severe withdrawal symptoms, and lethal overdose. Although still used in some situations, the barbiturates were replaced by benzodiazepines with the advent of Librium in 1960. By the late 1970s, benzodiazepines were the most commonly prescribed drugs in the world.. ...
In this study the depressant effect of fractions from P. glomerata was initially evaluated using the mice barbiturate sleeping time test as reference. The fractions tested were the CHCl3, the EtOAc, the n-BuOH and the aqueous fraction obtained from P. glomerata subterraneous parts. Only the pretreatment with the lipophilic fraction (CHCl3: EtOAc, 1:1, w/w) increased the barbiturate sleeping time (i.p 500 mg/kg; v.o. 1000 mg/kg). Ecdysterone, the main substance isolated from this lipophilic fraction, was identifi ed by spectroscopic methods and its content in the ethanol extract was determined as 1.4% (w/w) by HPLC. In order to investigate the hypothesis of ecdysterone displaying a depressant effect on nervous central system, an evaluation toward the hypnotic-sedative and anxiolytic effects of this drug was carried out. Ecdysterone 100 mg/kg, i.p, increased the barbiturate sleeping time without provoking hypothermia; when administered by oral route its minimal effective dose was 400 mg/kg. On the ...
Further, Consumers Union calls for three immediate steps to be taken in connection with the tragic deaths of many hundreds of heroin users each year from so-called overdose (see Chapter 12).. First, the dangerously wrong heroin overdose myth must be promptly exploded once and for all. Addicts and the public alike must be warned that sudden death can follow the intravenous injection of mixtures containing very little heroin or possibly none at all.. Second, heroin addicts throughout the country should be warned by all means available, including the fullest possible use of the mass media, that deaths falsely attributed to heroin overdose may be due to injecting heroin while drunk on alcohol or barbiturates. Although the evidence linking the many hundreds of so-called heroin overdose deaths to alcohol and the barbiturates is not conclusive, the evidence is conclusive that an addict who injects heroin while drunk on alcohol or barbiturates is running a far greater risk than one who shoots up ...

The most prevalent psychoactive substances in cannabis are cannabinoids, most notably THC. Some varieties, having undergone careful selection and growing techniques, can yield as much as 34% THC.[16] Another psychoactive cannabinoid present in Cannabis sativa is tetrahydrocannabivarin (THCV), but it is only found in small amounts and is a cannabinoid antagonist.[17] There are also similar compounds contained in cannabis that do not exhibit any psychoactive response but are obligatory for functionality: cannabidiol (CBD), an isomer of THC; cannabivarin (CBV), an analog of cannabinol (CBN) with a different side chain, cannabidivarin (CBDV), an analog of CBD with a different side chain, and cannabinolic acid. How these other compounds interact with THC is not fully understood. Some clinical studies have proposed that CBD acts as a balancing force to regulate the strength of the psychoactive agent THC. CBD is also believed to regulate the body's metabolism of THC by inactivating cytochrome P450, an ...
Some religious groups permit the consumption of alcohol. Some permit consumption but prohibit intoxication, while others prohibit alcohol consumption altogether. Many Christian denominations such as Catholic, Orthodox, and Lutheran use wine as a part of the Eucharist and permit the drinking of alcohol but consider it sinful to become intoxicated. In the Bible, the Book of Proverbs contains several chapters dealing with the bad effects of drunkenness and warning to stay away from intoxicating beverages. The book of Leviticus tells of Nadab and Abihu, Aaron the Priest's eldest sons, who were killed for serving in the temple after drinking wine, presumably while intoxicated. The book continues to discuss monasticism where drinking wine is prohibited. The story of Samson in the Book of Judges tells of a monk from the tribe of Dan who is prohibited from cutting his hair and drinking wine.[46] Romans 13:13-14,[47] 1 Corinthians 6:9-11, Galatians 5:19-21,[48] and Ephesians 5:18[49] are among a number ...

ICD-10 is an international statistical classification produced by the World Health Organization. It is used in health care and related industries in several countries around the world. Some have gone on to develop their own national enhancements, building off the international version of the classification. The fifth chapter of ICD-10 contains the International Classification of Mental and Behavioural Disorders. It is actually the official mental health system for the US as well, but even many professionals do not realize this due to the dominance of the DSM.[1] WHO have made Chapter V available as two separate publications.[2] The Clinical descriptions and diagnostic guidelines (or "Blue Book") is for clinical and general educational use. The Diagnostic criteria for research (or "Green Book") is intended for research purposes, and to be used in conjunction with the guidelines within it. ...
Moderate alcohol consumption 30-60 minutes before bedtime results in disruptions in sleep maintenance and sleep architecture that are mediated by blood alcohol levels.[2] Disruptions in sleep maintenance are most marked once alcohol has been completely metabolized from the body. Under conditions of moderate alcohol consumption where blood alcohol levels average 0.06-0.08% and decrease 0.01-0.02% per hour, an alcohol clearance rate of 4-5 hours would coincide with disruptions in sleep maintenance in the second half of an 8-hour sleep episode.[2] In terms of sleep architecture, moderate doses of alcohol facilitate "rebounds" in rapid eye movement (REM) and stage 1 sleep; following suppression in REM and stage 1 sleep in the first half of an 8-hour sleep episode, REM and stage 1 sleep increase well beyond baseline in the second half. Moderate doses of alcohol also increase slow wave sleep (SWS) in the first half of an 8-hour sleep episode.[2] Enhancements in REM sleep and SWS following moderate ...
In addition to ethanol and water, most alcoholic drinks also contain congeners, either as flavoring or as a by-product of fermentation and the wine aging process. While ethanol is by itself sufficient to produce most hangover effects, congeners may potentially aggravate hangover and other residual effects to some extent. Congeners include substances such as amines, amides, acetones, acetaldehydes, polyphenols, methanol, histamines, fusel oil, esters, furfural, and tannins, many but not all of which are toxic.[8] One study in mice indicates that fusel oil may have a mitigating effect on hangover symptoms,[19] while some whiskey congeners such as butanol protect the stomach against gastric mucosal damage in the rat.[20] Different types of alcoholic beverages contain different amounts of congeners. In general, dark liquors have a higher concentration while clear liquors have a lower concentration. Whereas vodka has virtually no more congeners than pure ethanol, bourbon has a total congener content ...

Drugs in the class of amphetamines, or substituted amphetamines, are known to induce "amphetamine psychosis" typically when chronically abused or used in high doses.[4] In an Australian study of 309 active methamphetamine users, 18% had experienced a clinical level psychosis in the past year.[5] Common amphetamines include cathinone, DOM, ephedrine, MDMA, methamphetamine, and methcathinone though a large number of such compounds have been synthesized. Methylphenidate is sometimes incorrectly included in this class, although is nonetheless still capable of producing stimulant psychosis.. The symptoms of amphetamine psychosis include auditory and visual hallucinations, delusions of persecution, and delusions of reference concurrent with both clear consciousness and prominent extreme agitation.[6][7] A Japanese study of recovery from methamphetamine psychosis reported a 64% recovery rate within 10 days rising to an 82% recovery rate at 30 days after methamphetamine cessation.[8] However it has been ...
The vitamin thiamine also referred to as Vitamin B1, is required by three different enzymes to allow for conversion of ingested nutrients into energy. [13] Thiamine can not be produced in the body and must be obtained through diet and supplementation. [23] The duodenum is responsible for absorbing thiamine. The liver can store thiamine for 18 days.[13] Prolonged and frequent consumption of alcohol causes a decreased ability to absorb thiamine in the duodenum. Thiamine deficiency is also related to malnutrition from poor diet, impaired use of thiamine by the cells and impaired storage in the liver. [23]Without thiamine the Kreb's Cycle enzymes pyruvate dehydrogenase complex (PDH) and alpha-ketoglutarate dehydrogenase (alpha-KGDH) are impaired.[13] The impaired functioning of the Kreb's Cycle results in inadequate production of adenosine triphosphate (ATP) or energy for the cells functioning. [13] Energy is required by the brain for proper functioning and use of its neurotransmitters. Injury to ...

  • Barbiturate use and abuse has declined dramatically since the 1970s, mainly because a safer group of sedative-hypnotics called benzodiazepines is being prescribed. (webmd.com)
  • A class of drugs known as benzodiazepines has largely replaced barbiturates for both medical and recreational use. (medicalnewstoday.com)
  • Benzodiazepines have less severe side effects and are not as likely to result in accidental overdose as barbiturates. (medicalnewstoday.com)
  • Until the benzodiazepines were introduced in the 1960s, barbiturates were widely used clinically for a range of indications, including the treatment of anxiety, insomnia, seizure disorders and as muscle relaxants and anesthetic agents. (acnp.org)
  • Benzodiazepines and the newer non-benzodiazepine hypnotics are now preferred over barbiturates for most of these clinical uses because they have a wider therapeutic index, tolerance develops more slowly, and their liability for abuse is lower than that of the barbiturates. (acnp.org)
  • We will also review the clinical pharmacology of this class of drugs, with particular attention to similarities and differences between barbiturates and benzodiazepines and their effects on sleep. (acnp.org)
