Barbiturates withdrawal from

Other sedative-hypnotic medications, such as barbiturates, may play a useful role in severe withdrawal from this group of drugs. For example, in a case series of GBL withdrawal, use of intravenous pentobarbital in the range of 1-2 mg/kg/hour lowered the total requirement for intravenous lorazepam (Sivilotti et al. 2001). Antipsychotic medications are often used to reduce psychotic agitation. However, because antipsychotic medications lower the seizure threshold and may contribute to loss of central control of temperature leading to hyperthermia or neuroleptic malignant syndrome (NMS), they are not indicated as first-line medications for GHB withdrawal delirium (Dyer and Roth 2001 McDaniel and Miotto 2001 Sharma et al. 2001). If anti-... 

Substance-Induced Anxiety Disorder. Numerous medicines and drugs of abuse can produce panic attacks. Panic attacks can be triggered by central nervous system stimulants such as cocaine, methamphetamine, caffeine, over-the-counter herbal stimulants such as ephedra, or any of the medications commonly used to treat narcolepsy and ADHD, including psychostimulants and modafinil. Thyroid supplementation with thyroxine (Synthroid) or triiodothyronine (Cytomel) can rarely produce panic attacks. Abrupt withdrawal from central nervous system depressants such as alcohol, barbiturates, and benzodiazepines can cause panic attacks as well. This can be especially problematic with short-acting benzodiazepines such as alprazolam (Xanax), which is an effective treatment for panic disorder but which has been associated with between dose withdrawal symptoms. 

Historically, the treatment of alcohol use disorders with medication has focused on the management of withdrawal from the alcohol. In recent years, medication has also been used in an attempt to prevent relapse in alcohol-dependent patients. The treatment of alcohol withdrawal, known as detoxification, by definition uses replacement medications that, like alcohol, act on the GABA receptor. These medications (i.e., barbiturates and benzodiazepines) are cross-tolerant with alcohol and therefore are useful for detoxification. By contrast, a wide variety of theoretical approaches have been used to reduce the likelihood of relapse. This includes aversion therapy and anticraving therapies using reward substitutes and interference approaches. Finally, medications to treat comorbid psychiatric illness, in particular, depression, have also been used in attempts to reduce the likelihood of relapse. 

The main drugs in this section are the barbiturates which can be considered as dry drink , and the withdrawal effects are very similar to the withdrawal from alcohol. Full-blown delirium tremens and epileptic fits can be observed and will need, usually, in-patient management and close supervision and sedation. 

The abrupt withdrawal from barbiturates may cause tremors, restlessness, anxiety, weakness, nausea and vomiting, seizures, delirium, and cardiac arrest. 

In some cases, withdrawal symptoms can be fatal, so a person cannot just stop taking barbiturates. The physician will establish a plan of gradual withdrawal from barbiturates. 

Barbiturates act so powerfully on the nervous system that a person must gradually withdraw from these drugs. To suddenly stop taking barbiturates could result in serious medical complications or death. This withdrawal process, known as detoxification, is part of the treatment process for people dependent on barbiturates. 

Barbiturates harm more people than those who take them. People who drive while intoxicated by barbiturates risk the lives of others. A pregnant woman who takes barbiturates passes the drugs along to her unborn baby. After the baby is bom, the infant will have to undergo withdrawal from the barbiturate. 

Furthermore, the method of withdrawing from barbiturates is not as simple as stopping completely. Barbiturates slow the brain s activity, so there could be a rebound when a person stops taking the drug. This... 

The nature of the withdrawal symptoms depends upon the neurotransmitter systems which are the target of the drug. Thus cocaine and the amphetamines alleviate fatigue, cause anorexia and elevate mood withdrawal therefore results in feelings of fatigue, hyperphagia and depression. Abrupt withdrawal from the sedatives, such as barbiturates or following... 

Most addicts realize that they will suffer a great amount of pain and discomfort from barbiturate withdrawal if they stop taking the drug. The withdrawal of barbiturates for an addict can be... 

One major reason for the movement away from the medical use of barbiturates involves tolerance and dependence. Tolerance develops fairly rapidly to many effects of the barbiturates. Whereas a given dose may be effective at inducing sleep for a while, if the drug is used regularly the patient soon may require a higher dose in order to sleep. If doses escalate too much and regular use persists, the patient will experience an abstinence syndrome when he or she attempts to withdraw from barbiturates. The symptoms of the barbiturate withdrawal syndrome are similar to those of alcohol— shakes, perspiration, confusion, and in some cases full-blown delirium tremens (DTs) (see Chapter 9)—but convulsions and seizures are more likely to occur in barbiturate... 

Withdrawal from barbiturates is similar to alcohol withdrawal. 

Withdrawal from certain classes of drugs (e.g., benzodiazepines or barbiturates) can be life-threatening, and steps... 

In the past several years, more than ever before, how to withdraw from barbiturates has been of paramount concern to a lot of dopers. Withdrawal from, say a six-month or longer steady habit of more than a few Reds a day (seconals), can be far more dangerous than anything you re ever likely to encounter. This requires constant medical attention and is best done in a hospital pr under doctor s supervision, in case seizures do occur. Best advice would be to explain the problem to a sympathetic doctor, free clinic, or public hospital (be careful of private hospitals). 

FACT Withdrawal from a heavy barbiturate habit can result in grand mal convulsions, and death, unless treated by a doctor or medical clinic, or in a detox facility. 

Acute barbiturate toxicity is characterized by automatism, or a state of drug-induced confusion, in which patients lose track of how much medication they have taken and take more. Death results from respiratory failure. The treatment of poisoning consists of supporting respiration, prevention of hypotension, as well as diuresis, hemodialysis and, in the event of phenobarbital poisoning, the administration of sodium bicarbonate. Tolerance does not develop from lethal doses. The abrupt withdrawal from barbiturates may cause tremors, restlessness, anxiety, weakness, nausea and vomiting, seizures, delirium, and cardiac arrest. 

There are two problems with regard to withdrawal from antiseizure drugs the effects of withdrawal itself and the need to continue suppression of seizures. Dose-tapering is an important principle in antiseizure drug withdrawal. As a rule, withdrawal from drugs used in absence seizures is easier than withdrawal from drugs used for partial and tonic-clonic seizures. Withdrawal is most difficult in patients who have been treated with barbiturates and benzodiazepines. The answer is (C). 

Alcohol, barbiturates, and narcotics—such as diphenhydramine (Benadryl), amobarbital (Amytal), diazepam (Valium), codeine, heroin, methadone, morphine, propoxyphene (Darvon)—that are used during pregnancy can lead to harmful effects on the newborn. Use of these dmgs during pregnancy can create an addiction in the newborn. The baby will go into withdrawal from the drug when they are born. This can result in hyperactivity, crying, irritability, seizures and even sudden death. 

Sensitivity to Convulsant Treatments - PCPA facilitates convulsions el-Icited by hyperbaric oxygen,39 pentylenetetrazolelectroconvulsive shock, Oa,41 audiogenic convulsant stimuli,42 flurothyl43 and withdrawal from barbiturates.44 a substantial older literature, originating with the work of Chen et al45 on reserpine, deals with the role of biogenic amines in experimental seizures. The preponderance of these reports indicate that stimulation of 5-HT receptor activity decreases seizure susceptibility, and that depression of 5-HT receptor activity exerts the opposite effect.
