Abstract: Cocaine abuse has produced a major epidemic health problem in North America in the 1980s. The abuse of cocaine is maintained by the drug's effects on brain reward systems, mediated at least in part by its dopaminergic action. The patterns and consequences of use are best understood by considering the pharmacokinetics (rapid absorption and delivery to the brain, relatively short half-life) and the pharmacodynamics (intense central and peripheral neural stimulation). Cocaine is used therapeutically as a topical and local anaesthetic. Toxicity occurs primarily in cocaine abusers, but also occasionally after therapeutic dosing. Medical complications reflect primarily excessive central nervous system stimulation and excessive vasoconstriction, the latter resulting in severe hypertension and/or organ ischaemia with associated organ injury. Most deaths that result from medical complications of cocaine intoxication are sudden and occur before medical intervention is possible. Other complications of cocaine abuse with severe personal and social consequences include traumatic deaths and injuries, and reproductive disturbances, as well as transmission of infectious diseases, especially AIDS. Cocaine addiction is clearly a problem, although the number of addicts is unknown. Pharmacologic treatment of cocaine addiction has as yet been unsuccessful. Psychosocial approaches remain the mainstay of therapy. 相似文献

5-Flourouracil(5-FU) is one of well known anti-cancer drugs, but its toxicity in normal lymphocytes remains a major problem in chemotherapy. The eastern traditional drug, Bupleuri radix(BR), has been used for the treatment of liver diseases and contains series of triterpene saponins. 相似文献

Epilepsy is a neurologic disorder affecting approximately 50 million people worldwide, or about 0.7% of the population [1]. Thus, the use of anticonvulsant drugs in the treatment of epilepsy is common and widespread. There are three generations of anticonvulsant drugs, categorized by the year in which they were developed and released. The aim of this review is to discuss the pharmacokinetics, drug-drug interactions, and adverse events of the third generation of anticonvulsant drugs. Where available, overdose data will be included. The pharmacokinetic properties of third-generation anticonvulsant drugs include relatively fewer drug-drug interactions, as well as several unique and life-threatening adverse events. Overdose data are limited, so thorough review of adverse events and knowledge of drug mechanism will guide expectant management of future overdose cases. Reporting of these cases as they occur will be necessary to further clarify toxicity of these drugs. 相似文献

Amoxapine, a new antidepressant, exhibits both antidepressant and neuroleptic effects in laboratory animals and in humans. Evidence from human studies (extrapyramidal reactions, hyperprolactinemia, and galactorrhea), animal screening tests, and neurochemical experiments support the contention that amoxapine or a metabolite occasionally produces neuroleptic-like effects. Amoxapine's neuroleptic activity may derive from 7-hydroxy-amoxapine, a minor metabolite in humans, which exhibits significant dopamine receptor-blocking activity. Evidence for an early antidepressant effect of amoxapine in the treatment of depressive illness has not been consistently demonstrated. In comparable doses (roughly twice the dose of imipramine or amitriptyline), amoxapine appears to be similar to reference antidepressants in efficacy, unwanted effects, and acute toxicity. 相似文献
