Serious complications after carbamazepine poisoning, such as coma, seizures, respiratory failure, cardiac conduction abnormalities, and death are more likely with serum levels greater than 170 micromol L(-1). We report a case of a single massive carbamazepine overdose in a 19-year-old male,

A rodent model of neurovisceral toxic syndrome induced by the neuroexcitant amino acid, domoic acid, is described, along with the activity of a putative antidote, the nonselective excitotoxin antagonist, kynurenic acid. Both an extract of contaminated mussels and pure domoic acid induced a

Experiments on male rats examined the effect of a basic antidotal therapy consisting of various types of anticholinergic substances and reactivators of acetylcholinesterase on the lethal effects of the highly toxic organophosphorous compound soman by means of determination of the medium lethal dose

Some organophosphorus compounds (OPs) are nerve agents that continue to concern military personnel and civilians as potential battlefield and terrorist threats. Additionally, OPs are used in agriculture where they are associated with numerous cases of intentional and accidental misuse. These

Of 53 patients with drug-induced seizures seen in the last decade, 45% had single seizures, 40% had multiple convulsions, and 15% had status epilepticus. Generalized seizures with focal features were common, but simple partial (motor) seizures occurred in only two patients. Isoniazid, insulin,

The antidotal, anticonvulsant and neuroprotective effects of physostigmine (PhS) and procyclidine (PC), the combinational prophylactics for organophosphate poisoning, were evaluated. For the investigation of dose-response relationship in rats and guinea pigs, various doses (0-6 mg/kg) of PC in

Chemical methods remain a credible threat in 1999. The doctrine for their use not only includes the battlefield but also domestic terrorism as was disclosed during the Tokyo metro attempt in 1995. International Treaties have not yet proven their efficacy. The arsenal of chemical weapons has changed

BACKGROUND The currently used antidotal treatment of intoxication with nerve agents, consisting of an anticholinergic drug and an acetylcholinesterase reactivator, is often completed with the anticonvulsive drug diazepam to prevent poisoned organisms from centrally mediated seizures and subsequent

Drug- and toxin-associated seizures (DTS) may result from exposure to a wide variety of agents. Most DTS can be managed with supportive care. First-line anticonvulsant therapy should include benzodiazepines, unless agents require a specific antidote. Phenytoin is generally not expected to be useful

In recent years, intravenous lipid emulsion (ILE) therapy has emerged as a new rescue antidote for treatment of certain toxicities, including cyclic antidepressants, and as the primary treatment of toxic manifestations after local anesthetic exposure. We present a case of a 13-year-old girl who

Local anaesthetics are routinely used for several indications, but despite local administration their use may lead to systemic toxicity. The symptoms include numbness of the tongue, dizziness, tinnitus, visual disturbances, muscle spasms, convulsions, coma, and respiratory and cardiac arrest.

Flumazenil is a benzodiazepine antagonist. It is widely used as an antidote in comatose patients suspected of having ingested a benzodiazepine overdose. Flumazenil is known to induce cardiac arythmias and seizures, in part because of drug interactions. We present a 75-year-old woman, who was brought

Cocaine, like catecholamines or angiotensin II, may induce lethal cardiac or cerebral damage. Restrained rats were fitted with a caudal arterial catheter for on-line cardiovascular monitoring and antidote administration. They were given 60 mg/kg of cocaine i.p., a dose which produces behavioral and

The clinical signs of ivermectin toxicity were determined in 6 groups of 10 epileptic and 8 non-epileptic chickens for 72 h after dosing with sc injections of 5.0, 7.5, 10.0, 12.5 or 15.0 mg ivermectin/kg bw. At the 5.0 mg/kg dose, mild diarrhea developed 4 h post-dosing and lasted until the end of

BACKGROUND Over the past 10 years the reported incidence of acute isoniazid (INH)-related poisonings has increased, with 507 cases reported in 1996. Parenteral pyridoxine is the antidote for INH-induced seizures, but 5-g aliquot recommended to treat an ingestion of unknown quantity of INH is not
