Spinal antinociceptive synergism between morphine and clonidine persists in mice made acutely or chronically tolerant to morphine. (1/3414)

Morphine (Mor) tolerance has been attributed to a reduction of opioid-adrenergic antinociceptive synergy at the spinal level. The present experiments tested the interaction of intrathecally (i.t.) administered Mor-clonidine (Clon) combinations in mice made acutely or chronically tolerant to Mor. ICR mice were pretreated with Mor either acutely (40 nmol i.t., 8 h; 100 mg/kg s.c., 4 h) or chronically (3 mg/kg s.c. every 6 h days 1 and 2; 5 mg/kg s.c. every 6 h days 3 and 4). Antinociception was detected via the hot water (52.5 degrees C) tail-flick test. After the tail-flick latencies returned to baseline levels, dose-response curves were generated to Mor, Clon, and Mor-Clon combinations in tolerant and control mice. Development of tolerance was confirmed by significant rightward shifts of the Mor dose-response curves in tolerant mice compared with controls. Isobolographic analysis was conducted; the experimental combined ED50 values were compared statistically against their respective theoretical additive ED50 values. In all Mor-pretreated groups, the combination of Mor and Clon resulted in significant leftward shifts in the dose-response curves compared with those of each agonist administered separately. In all tolerant and control groups, the combination of Mor and Clon produced an ED50 value significantly less than the corresponding theoretical additive ED50 value. Mor and Clon synergized in Mor-tolerant as well as in control mice. Spinally administered adrenergic/opioid synergistic combinations may be effective therapeutic strategies to manage pain in patients apparently tolerant to the analgesic effects of Mor.  (+info)

Characterization of the analgesic and anti-inflammatory activities of ketorolac and its enantiomers in the rat. (2/3414)

The marked analgesic efficacy of ketorolac in humans, relative to other nonsteroidal anti-inflammatory drugs (NSAIDs), has lead to speculation as to whether additional non-NSAID mechanism(s) contribute to its analgesic actions. To evaluate this possibility, we characterized (R,S)-ketorolac's pharmacological properties in vivo and in vitro using the nonselective cyclooxygenase (COX) inhibitors [indomethacin (INDO) and diclofenac sodium (DS)] as well as the selective COX-2 inhibitor, celecoxib, as references. The potency of racemic (R,S)-ketorolac was similar in tests of acetic acid-induced writhing, carrageenan-induced paw hyperalgesia, and carrageenan-induced edema formation in rats; ID50 values = 0.24, 0. 29, and 0.08 mg/kg, respectively. (R,S)-ketorolac's actions were stereospecific, with (S)-ketorolac possessing the biological activity of the racemate in the above tests. The analgesic potencies for (R,S)-, (S)-, and (R)-ketorolac, INDO, and DS were highly correlated with their anti-inflammatory potencies, suggesting a common mechanism. (R,S)-ketorolac was significantly more potent than INDO or DS in vivo. Neither difference in relative potency of COX inhibition for (R,S)-ketorolac over INDO and DS nor activity of (S)-ketorolac at a number of other enzymes, channels, or receptors could account for the differences in observed potency. The distribution coefficient for (R,S)-ketorolac was approximately 30-fold less than for DS or INDO, indicating that (R,S)-ketorolac is much less lipophilic than these NSAIDs. Therefore, the physicochemical and pharmacokinetics properties of (R,S)-ketorolac may optimize the concentrations of (S)-ketorolac at its biological target(s), resulting in greater efficacy and potency in vivo.  (+info)

Cannabinoid suppression of noxious heat-evoked activity in wide dynamic range neurons in the lumbar dorsal horn of the rat. (3/3414)

The effects of cannabinoid agonists on noxious heat-evoked firing of 62 spinal wide dynamic range (WDR) neurons were examined in urethan-anesthetized rats (1 cell/animal). Noxious thermal stimulation was applied with a Peltier device to the receptive fields in the ipsilateral hindpaw of isolated WDR neurons. To assess the site of action, cannabinoids were administered systemically in intact and spinally transected rats and intraventricularly. Both the aminoalkylindole cannabinoid WIN55,212-2 (125 microg/kg iv) and the bicyclic cannabinoid CP55,940 (125 microg/kg iv) suppressed noxious heat-evoked activity. Responses evoked by mild pressure in nonnociceptive neurons were not altered by CP55,940 (125 microg/kg iv), consistent with previous observations with another cannabinoid agonist, WIN55,212-2. The cannabinoid induced-suppression of noxious heat-evoked activity was blocked by pretreatment with SR141716A (1 mg/kg iv), a competitive antagonist for central cannabinoid CB1 receptors. By contrast, intravenous administration of either vehicle or the receptor-inactive enantiomer WIN55,212-3 (125 microg/kg) failed to alter noxious heat-evoked activity. The suppression of noxious heat-evoked activity induced by WIN55,212-2 in the lumbar dorsal horn of intact animals was markedly attenuated in spinal rats. Moreover, intraventricular administration of WIN55,212-2 suppressed noxious heat-evoked activity in spinal WDR neurons. By contrast, both vehicle and enantiomer were inactive. These findings suggest that cannabinoids selectively modulate the activity of nociceptive neurons in the spinal dorsal horn by actions at CB1 receptors. This modulation represents a suppression of pain neurotransmission because the inhibitory effects are selective for pain-sensitive neurons and are observed with different modalities of noxious stimulation. The data also provide converging lines of evidence for a role for descending antinociceptive mechanisms in cannabinoid modulation of spinal nociceptive processing.  (+info)

Pharmacological studies on root bark of mulberry tree (Morus alba L.) (4/3414)

Pharmacological studies were done on the root bark of mulberry tree and pharmacological effects were compared with the clinical effects of "Sohakuhi" in Chinese medicine. n-Butanol- and water-soluble fractions of mulberry root had similar effects except for those on the cadiovascular system. Both fractions showed cathartic, analgesic, diuretic, antitussive, antiedema, sedative, anticonvulsant, and hypotensive actions in mice, rats, guinea pigs and dogs. There appears to be a correlation between the experimental pharmacological results and the clinical applications of mulberry root found in the literature on Chinese medicine.  (+info)

Incidence of analgesic nephropathy in Berlin since 1983. (5/3414)

BACKGROUND: Phenacetin was removed from the German market in 1986 and was replaced mainly in analgesic compounds by acetaminophen. Our objective was to examine the effect of this measure on the incidence of analgesic nephropathy in light of the changes in other end-stage renal diseases. METHODS: We therefore compared the proportion of renal diseases in all patients starting dialysis treatment during three 18-month periods: 4/1982-9/1983 (n=57); 1/1991-6/1992 (n=81); and 10/1995-3/1997 (n=76). RESULTS: On the one hand, the proportion of end-stage analgesic nephropathy decreased significantly from 30% in 1981-1982 to 21% in 1991-1992 and 12% in 1995-1997 (P=0.01). On the other hand, type II diabetes increased significantly from 7% to 22% (P=0.01) and 29%, (P=0.001). Using the chi2 distribution test to analyze the frequencies of seven diseases at three different time intervals, however, showed that the changes in renal-disease proportions between 1982-1983, 1991-1992 and 1995-1997 were not significantly independent. There was a significant median age increase from 52 years (CI0.95 44-58) in 1982-1983 to 63 (CI0.95 55-67) in 1991-1992 and 63 (CI0.95 60-66) in 1995-1997 (P=0.003) for all patients starting dialysis but not for those with analgesic nephropathy [59 (55-71) vs 64 (53-67) and 61 (50-72); n.s.]. CONCLUSION: The decrease of end-stage analgesic nephropathy since 1983 may be partially due to the removal of phenacetin from the German market in 1986. However, considering the general increase in numbers of dialysis patients, their higher age and the increased incidence of type II diabetes, the decrease in analgesic nephropathy is not a statistically significant independent variable. Altered admittance policies for dialysis treatment have yielded a new pattern of renal-disease proportion which interferes with changes in the incidence of analgesic nephropathy.  (+info)

Prevalence and treatment of pain in older adults in nursing homes and other long-term care institutions: a systematic review. (6/3414)

BACKGROUND: The high prevalence of pain in older adults and its impact in this age group make it a public health issue, yet few studies of pain relief focus on older adults. Residents of long-term care facilities have more cognitive impairment than their community-living counterparts and may have difficulty reporting the presence and severity of pain. This systematic literature review was conducted to determine the prevalence of pain, and the type and effectiveness of interventions that have been used to treat pain in residents of nursing homes. METHODS: Studies were identified by searching MEDLINE (from January 1966 to May 1997), HEALTH (from January 1975 to May 1997), CINAHL (from January 1982 to April 1997), AGELINE (from January 1978 to April 1997) and the Cochrane Library (1997, issue 1) and by performing a manual search of textbooks and reference lists. Studies of any methodological design were included if they estimated the prevalence of pain in nursing homes or other long-term care institutions or evaluated interventions for the treatment of pain in residents. Of the 14 eligible studies, 12 were noncomparative studies, 1 was a comparison study with nonrandomized contemporaneous controls, and 1 was a randomized controlled trial. Information on several factors was extracted from each study, including study design, number of patients and facilities, main outcomes measured, methods used to identify and detect pain, prevalence and types of pain, and interventions used to treat pain. The strength of the evidence provided by each study was also assessed. RESULTS: In the 6 studies with data from self-reporting or chart reviews, the prevalence of pain ranged from 49% to 83%. In the 5 studies with data on analgesic use only, the prevalence of pain ranged from 27% to 44%. Only 3 studies, with just 30 patients in total, evaluated an intervention for the treatment of pain. INTERPRETATION: Despite the high prevalence of pain in residents of nursing homes, there is a lack of studies evaluating interventions to relieve their pain. The authors make recommendations for future studies in this area.  (+info)

Evaluation of lidocaine as an analgesic when added to hypertonic saline for sclerotherapy. (7/3414)

PURPOSE: The efficacy of sclerosing agents for the treatment of telangiectasias and reticular veins is well established. The injection of these agents is often associated with pain, and it is not uncommon for sclerotherapists to include lidocaine with the sclerosants in an attempt to reduce the pain associated with treatment. However, there are concerns that this may reduce the overall efficacy of the treatment because of dilution of the sclerosant. Patient comfort and overall outcome associated with treatment using HS with lidocaine (LIDO) versus that using HS alone was compared. METHODS: Forty-two patients were prospectively entered into the study and randomized blindly to sclerotherapy with 23.4% HS or 19% LIDO. Study subjects and treating physicians were blinded to the injection solution used. Injection sites were chosen for veins ranging in size from 0.1 to 3 mm. Photographs of the area to be treated were taken, and the patients rated their pain. They were then observed at regular intervals for four months, and clinical data was collected. Thirty-five subjects completed the full follow-up period, and photographs of the injected area were taken again. Three investigators blinded to the treatment assignment then evaluated the photographs and scored the treatment efficacy according to a standardized system. RESULTS: In the HS group, 61.9% (13 of 21) patients rated their pain as none or mild, whereas 90.5% (19 of 21) of patients in the LIDO group had no or mild discomfort. This difference is significant, with a P value of.034. There was no difference in the overall efficacy of treatment between the two groups. The groups had similar rates of vein thrombosis and skin necrosis. CONCLUSION: Although lidocaine is often used with sclerosing agents, there are no previous reports in the literature to evaluate its effectiveness in reducing the pain experienced by the patient. In this study, patients receiving LIDO experienced significantly less discomfort at the time of injection than patients who received HS alone. There were no differences in the effectiveness of treatment or in the incidence of complications between the two groups.  (+info)

Ketamine-induced peripheral analgesia in rats. (8/3414)

AIM: To examine whether ketamine may directly act at peripheral nociceptors to produce analgesia. METHODS: Wistar rats were anesthetized with urethane. As a nociceptive flexion reflex (FR), C responses from the posterior biceps semitendinosus (PBST) muscle was evoked by electrical stimulation (2 ms, 80 V, 2-3 pulses, 0.5 Hz) via a pair of stainless steel needles inserted subcutaneously applied to the two toes of ipsilateral hindpw. RESULTS: Subcutaneous injection of ketamine (36 mmol.L-1, 5 microL) into the ipsilateral hindpaw produced an inhibition of C responses. At 9 min after application of ketamine, injection of naloxone (1%, 5 microL) into the same area annulled ketamine-induced inhibition. CONCLUSION: Ketamine as a dissociate anesthetic acts on peripheral nociceptors to produce analgesia, which is related to activity of peripheral opioid receptors.  (+info)

BioAssay record AID 130353 submitted by ChEMBL: In vivo antinociceptive activity was determined using mouse acetylcholine induced abdominal constriction test following subcutaneous administration; range (0.23-0.70).
Choice of a narcotic painkiller should be determined by a number of factors, the main ones are etiology, intensity and type of pain. It is also should be taken into account the patients age and individual characteristics.. Effectiveness of anesthesia depends not only by the analgesic itself, but also by route of its administration. Narcotic painkillers should be administered by the most effective, convenient and least painful way.. Parenteral administration of narcotic painkillers can be an effective way to achieve the required level of analgesia in patients who cannot get the desired effect by oral or transdermal route of analgesic administration.. Subcutaneous and intramuscular are the main parenteral routes of administration of narcotic painkillers. In those cases when it is necessary to quickly stop pain syndrome, intravenous route of analgesic administration is used.. Spinal administration of narcotic painkillers (epidural and intrathecal) is used in some patients in the presence of ...
DMSO produces analgesia in rats on tests that typically only detect the analgesic effects of potent narcotic analgesic drugs (i.e. the hot-plate and tail-flick tests). There seem to be two components of this analgesic effect; one component related to a local effect and the other component related to a systemic effect. If only the feet are exposed to DMSO, the rat becomes analgesic on the hot-plate and tail-flick. If a greater surface body is exposed, the rat becomes analgesic on both the hot plate and tail flick indicating a central action, because the tail did not come into contact with the DMSO. In one study on patients the authors conclude that the analgesic effect of DMSO arises from a central, not local, analgesic effect. The analgesic effects of DMSO are not consistently blocked by naloxone indicating that these analgesic effects of DMSO are not consistently blocked by naloxone indicating that these analgesic effects of DMSO do not have the same mechanism of action as morphine.*Methyl sulfoxide
According to the U.S. Centers for Disease Control and Prevention (CDC), opioid painkillers double the risk of birth defects in pregnant women - an alarming fact considering that more and more women, ages 15 to 44, are being prescribed narcotic painkillers in the United States.. In a recent study, the CDC found that roughly 39 percent of pregnant women enrolled in Medicaid and 28 percent of those enrolled in private insurance were prescribed opioids despite the well-known risks to the developing fetus.. Opioid painkillers, such as codeine, hydrocodone, and oxycodone, are prescribed to treat moderate to acute pain. However, due to their highly addictive properties, the development of a physical dependence on opioids is a common issue, and well known to healthcare providers. Overuse of prescription painkillers has become a serious, life-threatening problem throughout the United States. The number of addictions, deaths, and even motor vehicle and other accidents associated with the use of the ...

Is someone really an addict if they have been prescribed medication for pain and can no longer function without the substance? They are certainly dependent on the painkiller but they are not necessarily an addict. They may well need clinical help coming off the substance due to the physical withdrawals they may experience. If they have maintained using the painkiller as prescribed and have not varied from the prescribed regime I would suggest they are not an addict in the sense of addiction diagnosed as a disease. The addiction as a disease model states that an addict will have lost the ability to control the use of the substance. That once they take the first one they will be compelled to consume more alongside being obsessed to use more. They will continue to use the drug despite negative consequences.. So it appears there are two issues running side by side here. Those that are using prescribed painkillers addictively and those that are using painkillers as prescribed but are struggling to ...
What You Need to Know Before You Take Any Painkillers. Do you use any form of painkillers regularly? If you answered yes, there are a few critical things you should know. Since painkillers are easily accessible, many people have made them their best friend. It is common for many people to take painkillers every time they develop back pain and or muscle pull.

Amid growing concerns about a nationwide epidemic of painkiller addiction and abuse, the U.S. Centers for Disease Control and Prevention has come out with new federal guidelines on the use of powerful drugs like OxyContin and Vicodin. The guidelines are designed for doctors and aim to reduce the overprescribing of opioid drugs.. Prescription painkillers should not be a first-choice for treating common ailments like back pain and arthritis, according to the new guidelines, which are voluntary for doctors to follow. Instead, patients should be encouraged to try physical therapy, exercise and over-the-counter pain medications before turning to opioid painkillers for chronic pain. Opioid drugs include medications like morphine and oxycodone as well as illegal narcotics like heroin ...

Worried that your painkiller could trigger a heart attack or dangerous stomach bleeding? New reports on painkiller risks, based on reviews of dozens of studies including hundreds of thousands of patients, indicate most patients should try naproxen, an older anti-inflammatory drug. Experts say it doesnt raise heart attack or stroke risk - a major worry for older people - and naproxen is inexpensive because generic versions have been around for years. Available over the counter, its taken by millions of Americans. The drawback is that like most painkillers, it can irritate the stomach, so doctors say some people may also need to take one of the newer acid reflux drugs. "I do think we should start with naproxen in the vast majority of cases," said Dr. Steven Nissen, head of cardiology at the Cleveland Clinic and president of the American College of Cardiology. "Its about balancing the cardiovascular and gastrointestinal risk." The new reports were published Tuesday ahead of schedule on the ...

The tail flick test is a test of the pain response in animals, similar to the hot plate test. It is used in basic pain research and to measure the effectiveness of analgesics, by observing the reaction to heat. It was first described by DAmour and Smith in 1941. Most commonly, an intense light beam is focused on the animals tail and a timer starts. When the animal flicks its tail, the timer stops and the recorded time (latency) is a measure of the pain threshold. Alternate methods can be used to apply heat, such as immersion in hot water. Alternately, a dolorimeter with a resistance wire with a constant heat flow may be used. For the tail flick test, the wire is attached to the tail of the organism, and the wire applies heat to the tail. The researcher then records the latency to tail flick. Researchers testing the effectiveness of drugs on the pain threshold often use the tail flick test to measure the extent to which the drug being tested has reduced the amount of pain felt by the model ...

Analgesics (pain killers) are an important component of medicines ability to reduce suffering.. Multiple analgesics are available and vary from Aspirin (the old favourite) to morphine and its synthetic derivatives.. However all analgesics are not equal. Analgesics and anti-inflammatory drugs are often confused and sometimes not used appropriately. Prednisone is an excellent anti-inflammatory drug but has no direct analgesic effect. It produces results by reducing inflammation and hence "the process causing pain". Other anti-inflammatory drugs have been developed to produce a similar effect.. Side effects that can be present with long term Prednisone use.. Aspirin has an excellent analgesic and an excellent anti-inflammatory action. Paracetamol (Panadol) has an excellent analgesic effect but is not as good an anti-inflammatory drug as Aspirin..

WebMD Health News. Opioid painkillers - also known as narcotic painkillers - are powerful drugs that can effectively treat pain when needed. But they are also potential killers: in 2013, they were linked to 16,000+ deaths, more than any other drug or drug class. And nearly 5 million people could be addicted to the drugs, says a new report from the Johns Hopkins Bloomberg School of Public Health.. The report, called "The Prescription Opioid Epidemic: An Evidence-Based Approach," offers a number of solutions to the problem. One is to expand access to an addiction treatment called buprenorphine.

Abstract: Pain is a distressing feeling caused by damage to different tissues. Consequently the person reacts, and tries to remove the painful stimulus. On the other hand, prostaglandins contribute to the emergence of pain. These compounds are formed and secreted by cyclogenase 2 or COX-2 enzymes. It is through inhibiting these enzymes that most of the analgesic medications act. Thus, this study aims to investigate and review some of the scientific findings on analgesic effects and possible active ingredients and analgesic mechanisms of these herbs. Result: Nowadays one of the methods to control pain is using non-steroid anti-inflammatory medications. Although the analgesic effects of these medications emerge relatively fast, but their side effects are considered to be a limiting factor in their usage. Therefore researchers are constantly in the search of new medications with less side effects. In recent years the tendency to use herbal medications has significantly increased in the treatment ...

Given the structural diversity, and biological and toxicity profiles, these molecules represent a new avenue in the search of molecules with antinociceptive activity.. Keywords : UNIIQUIM; traditional Mexican medicine; analgesics; nociception; toxicity profile. ...
We found that 27% of the women and 18% of the men reported a regular monthly use of at least seven analgesic tablets during the last year (continuous regular analgesics use). Besides poor self-rated health we found in both sexes that increasing age, poor self-rated fitness, and smoking were related to a continuous regular analgesics use. Nulliparity, low level of education, overweight/obesity, binge drinking, and abstinence were associated with a continuous regular analgesics use for women, while underweight and marital/cohabiting status were associated with a continuous regular analgesics use only for men. ...
Results At baseline 84% of the patients used analgesics. Of all patients, 77% used acetaminophen, 36% used NSAIDs and 16% used weak opioids. At baseline, analgesics were used irregularly and at an suboptimal dose. Analgesic use after six weeks is described in Figure 1. The maximal daily dosage was used in 93% of the patients that used acetaminophen, in 66% of the patients that used NSAIDs, and in 44% of the patients that used weak opioids. Combinations of analgesics were common. No serious adverse events occurred. In 39% of the patients NRS-pain was ≤5 after six weeks. Despite NRS-pain,5, a further step in the analgesic protocol was not accepted by the patient (n=14) or not prescribed by the rheumatologist (n=13), the latter mostly due to contra-indications or side effects. Statistically significant and clinically relevant mean improvements from baseline were 19% (p,0.001) for pain and 12% (p=0.002) for activity limitations after six weeks. ...

TUESDAY, May 9, 2017 (HealthDay News) -- Commonly used painkillers such as Motrin, Advil and Aleve might increase your risk for heart attack, even in the first week of use, a new study suggests. Overall, these drugs and others known as nonsteroidal anti-inflammatory drugs (NSAIDs) increase the risk of a heart attack by 20 to 50 percent, compared with not using them, researchers found.. For most people, however, this represents only a small increased risk -- about 1 percent a year, the researchers said. Still, "from the viewpoint of public health, even small increases in risk of heart attack are important because use of NSAIDs is so widespread," said lead researcher Michele Bally. Shes an epidemiologist at the University of Montreal Hospital Research Center. The increased risk of heart attack associated with NSAIDs was seen at any dose taken for one week, one month or more than one month. And the risk rose with higher doses, the study found.. NSAIDs are widely used to treat pain and inflammation ...
PARACETAMOL is a commonly used medicine that can help treat pain and reduce a high temperature. However, the common over-the-counter painkiller can interact with some other medications - including drugs to prevent stroke and even type 2 diabetes medication.
Not all pain is equal, and neither are painkillers. Pain is one of the most common symptoms and its presence is almost ubiquitous in all diseases and injuries, hence this is an important area for all healthcare professionals to note.

Inefficient drug delivery to the brain is a major obstacle for pharmacological management of brain diseases. We investigated the ability of bolavesicles - monolayer membrane vesicles self-assembled from synthetic bolaamphiphiles that contain two hydrophilic head groups at each end of a hydrophobic alkyl chain - to permeate the blood-brain barrier and to deliver the encapsulated materials into the brain. Cationic vesicles with encapsulated kyotorphin and leu-enkephalin (analgesic peptides) were prepared from the bolalipids GLH-19 and GLH-20 and studied for their analgesic effects in vivo in experimental mice. The objectives were to determine: (a) whether bolavesicles can efficiently encapsulate analgesic peptides, (b) whether bolavesicles can deliver these peptides to the brain in quantities sufficient for substantial analgesic effect, and to identify the bolavesicle formulation/s that provides the highest analgetic efficiency. The results indicate that the investigated bolavesicles can deliver ...
Many patients (including the general public) believe that marijuana is a legitimate treatment option for people suffering from chronic pain.. But what does the science say?. Fortunately, weeds painkilling properties have been studied the most, out of all its effects.. The discovery of the endocannabinoid system and cannabinoid receptors in the human body in the last two decades of the 20th century made clinicians think - can marijuana be used to treat pain?. So thats when the research started…But it progressed slowly.. A number of studies have shown that cannabinoids have an impact on pain signalling cells in our body, turning off those signals so we dont feel the pain. Cannabinoids have been proven to be very effective at reducing neuropathic pain and inflammation. They triumphed where common pharmaceutical painkillers failed.. As it turns out, cannabinoids have antinociceptive mechanisms that are different from common, artificially made, painkillers. This leaves a lot of space for ...

London, March 18 (IANS) Non-steroidal anti-inflammatory drugs (NSAIDs) are often prescribed to treat a variety of painful conditions but popping these pain-killers may be putting you at the risk of ulcers, increased blood pressure and heart problems, warns a new study. "Its been well known for a number of years that newer types of NSAIDs - what are known as COX-2 inhibitors - increase the risk of heart attacks," said Morten Schmidt from Denmarks Aarhus University, who was in-charge of the study. "For this reason, a number of these newer types of NSAIDs have been taken off the market again. We can now see that some of the older NSAID types, particularly Diclofenac, are also associated with an increased risk of heart attack and apparently to the same extent as several of the types that were taken off the market," Schmidt added.. The study, published in the European Heart Journal, emphasised that arthritis medicine is particularly dangerous for heart patients, and also that older types of ...
by Ola van Zyl DipNT mNTOI. Pain relief medications can cause significant side-effects. The experts slowly realise that this problem may be much greater than previously thought. That is why natural pain killers are bringing more and more attention.. A Canadian study published last month showed that drugs such as ibuprofen more than doubled the risk of miscarriage among pregnant women. The women studied had been given at least one prescription for NSAIDs from the start of their pregnancy.. Meanwhile, a recent U.S. study found an increase in the risk of renal cell cancer among those taking the painkillers regularly for four to ten years.. NSAIDs have been linked to a 22 per cent increased risk of erectile dysfunction if taken three times a day for more than three months.. Non-steroidal anti-inflammatories work by interfering with specific enzymes in the body, the cyclo-oxygenase or cox enzymes. Cox enzymes trigger inflammation - NSAIDs prevent this happening.. For this reason, they are used to ...

... is a member of the sodium channel blocking class of antiepileptic drugs.[60] This may suppress the release of glutamate and aspartate, two of the dominant excitatory neurotransmitters in the CNS.[61] It is generally accepted to be a member of the sodium channel blocking class of antiepileptic drugs,[62] but it could have additional actions since it has a broader spectrum of action than other sodium channel antiepileptic drugs such as phenytoin and is effective in the treatment of the depressed phase of bipolar disorder, whereas other sodium channel blocking antiepileptic drugs are not, possibly on account of its sigma receptor activity. In addition, lamotrigine shares few side-effects with other, unrelated anticonvulsants known to inhibit sodium channels, which further emphasises its unique properties.[63] It is a triazine derivate that inhibits voltage-sensitive sodium channels, leading to stabilization of neuronal membranes. It also blocks L-, N-, and P-type calcium channels and ...
The hormone prolactin stimulates lactation (production of breast milk). Dopamine, released by the hypothalamus stops the release of prolactin from the pituitary gland. Domperidone, by acting as an anti-dopaminergic agent, results in increased prolactin secretion, and thus promotes lactation (that is, it is a galactogogue). In some nations, including Australia, domperidone is used off-label, based on uncertain and anecdotal evidence of its usefulness, as a therapy for mothers who are having difficulty breastfeeding.[24][25] In the United States, domperidone is not approved for this or any other use.[26][27] A study called the EMPOWER trial was designed to assess the effectiveness and safety of domperidone in assisting mothers of preterm babies to supply breast milk for their infants.[28] The study randomized 90 mothers of preterm babies to receive either domperidone 10 mg orally three times daily for 28 days (Group A) or placebo 10 mg orally three times daily for 14 days followed by domperidone ...

... (CBZ), sold under the trade name Tegretol among others, is an anticonvulsant medication used primarily in the treatment of epilepsy and neuropathic pain.[1] It is not effective for absence or myoclonic seizures.[1] It is used in schizophrenia along with other medications and as a second-line agent in bipolar disorder.[3][1] Carbamazepine appears to work as well as phenytoin and valproate for focal and generalised seizures.[4] Common side effects include nausea and drowsiness.[1] Serious side effects may include skin rashes, decreased bone marrow function, suicidal thoughts, or confusion.[1] It should not be used in those with a history of bone marrow problems.[1] Use during pregnancy may cause harm to the baby; however, stopping the medication in pregnant women with seizures is not recommended.[1] Its use during breastfeeding is not recommended.[1] Care should be taken in those with either kidney or liver problems.[1] Carbamazepine was discovered in 1953 by Swiss chemist Walter ...
A channel that is "inwardly-rectifying" is one that passes current (positive charge) more easily in the inward direction (into the cell) than in the outward direction (out of the cell). It is thought that this current may play an important role in regulating neuronal activity, by helping to stabilize the resting membrane potential of the cell. By convention, inward current (positive charge moving into the cell) is displayed in voltage clamp as a downward deflection, while an outward current (positive charge moving out of the cell) is shown as an upward deflection. At membrane potentials negative to potassium's reversal potential, inwardly rectifying K+ channels support the flow of positively charged K+ ions into the cell, pushing the membrane potential back to the resting potential. This can be seen in figure 1: when the membrane potential is clamped negative to the channel's resting potential (e.g. -60 mV), inward current flows (i.e. positive charge flows into the cell). However, when the ...
... also binds to and blocks α2δ subunit-containing VDCCs, similarly to gabapentin and pregabalin, and hence is a gabapentinoid.[9][16] Both (R)-phenibut and (S)-phenibut display this action with similar affinity (Ki = 23 and 39 μM, respectively).[9] Moreover, (R)-phenibut possesses 4-fold greater affinity for this site than for the GABAB receptor (Ki = 92 μM), while (S)-phenibut does not bind significantly to the GABAB receptor (Ki , 1 mM).[9] As such, based on the results of this study, phenibut would appear to have much greater potency in its interactions with α2δ subunit-containing VDCCs than with the GABAB receptor (between 5- to 10-fold).[9] For this reason, the actions of phenibut as a α2δ subunit-containing voltage-gated calcium channel blocker or gabapentinoid may be its true primary mechanism of action, and this may explain the differences between phenibut and its close relative baclofen (which, in contrast, has essentially insignificant activity as a gabapentinoid; Ki = 6 ...

... (marketed as Depamide by Sanofi-Aventis) is a carboxamide derivative of valproic acid used in the treatment of epilepsy and some affective disorders. It is rapidly metabolised (80%) to valproic acid (another anticonvulsant) but has anticonvulsant properties itself. It may produce more stable plasma levels than valproic acid or sodium valproate and may be more effective at preventing febrile seizures. However, it is over one hundred times more potent as an inhibitor of liver microsomal epoxide hydrolase. This makes it incompatible with carbamazepine and can affect the ability of the body to remove other toxins. Valpromide is no safer during pregnancy than valproic acid. Valpromide is formed through the reaction of valproic acid and ammonia via an intermediate acid chloride. In pure form, valpromide is a white crystalline powder and has melting point 125-126 °C. It is practically insoluble in water but soluble in hot water. It is available on the market in some European countries. ...

... has a potential for drug interactions; caution should be used in combining other medicines with it, including other antiepileptics and mood stabilizers.[12] Lower levels of carbamazepine are seen when administrated with phenobarbital, phenytoin, or primidone, which can result in breakthrough seizure activity. Carbamazepine, as a CYP450 inducer, may increase clearance of many drugs, decreasing their concentration in the blood to subtherapeutic levels and reducing their desired effects.[19] Drugs that are more rapidly metabolized with carbamazepine include warfarin, lamotrigine, phenytoin, theophylline, and valproic acid.[12] Drugs that decrease the metabolism of carbamazepine or otherwise increase its levels include erythromycin,[20] cimetidine, propoxyphene, and calcium channel blockers.[12] Carbamazepine also increases the metabolism of the hormones in birth control pills and can reduce their effectiveness, potentially leading to unexpected pregnancies.[12] As a drug that induces ...

... occludes the pore of calcium-activated voltage-gated shaker K+ channels by binding to one of four independent, overlapping binding sites.[6][7] It binds both to the open and the closed states. In addition, the block is enhanced as the ionic strength is lowered.[8] This block occurs as the Asn 30 on the CTX interacts with the Asp 381 on the K+ channel.[9] The blockade of K+ channels by the charybdotoxin peptide causes neuronal hyperexcitability. Mutations of the Lys31Gln and the Asn30Gln had the effect of lessening the CTX block of the pore on the shaker channel.[9] ...
... has several uses including the treatment of abnormal heart rhythms or arrhythmias, chronic pain, and myotonia. In general when treating arrhythmias, mexiletine is reserved for use in dangerous heart rhythm disturbances such as ventricular tachycardia.[2] It is of particular use when treating arrhythmias caused by long QT syndrome.[3] The LQT3 form of long QT syndrome is amenable to treatment with mexiletine as this form is caused by defective sodium channels that continue to release a sustained current rather than fully inactivating, however other forms of long QT syndrome can also be treated with this medication.[3] Mexiletine has been used to treat chronic pain and may also be used to treat muscle stiffness resulting from myotonic dystrophy (Steinert's disease) or nondystrophic myotonias such as myotonia congenita (Thomsen syndrome or Becker syndrome).[4][5] ...

(The xxmg in the name refers to the strength-for example "Phenytoin sodium 25 mg Flynn Hard Capsules").[49] The capsules are still made by Pfizer's Goedecke subsidiary's plant in Freiburg, Germany and they still have Epanutin printed on them.[50] After Pfizer's sale of the UK marketing licence to Flynn Pharma, the price of a 28-pack of 25 mg phenytoin sodium capsules marked Epanutin rose from 66p (about $0.88) to £15.74 (about $25.06). Capsules of other strengths also went up in price by the same factor-2384%,[51] costing the UK's National Health Service an extra £43 million (about $68.44 ...
