title: Value of flumazenil in benzodiazepine self-poisoning.
abstract: The efficacy of the benzodiazepine-antagonist flumazenil (Ro 15-1788) was evaluated in 26 patients with coma due to benzodiazepine self poisoning, alone or in combination with alcohol or other psychoactive drugs. 77% of the patients responded to the administration of a mean dose of 1.73 mg (range 0.2 to 8 mg) with immediate awakening or an improvement of at least 2 coma grades. In the patients without response (n = 3) or with minor improvement (n = 3) other psychoactive drugs turned out to be predominantly responsible for their comatose state. Adverse effects of flumazenil treatment such as altered blood pressure or increased heart rate were observed, but were generally mild. An acute benzodiazepine withdrawal syndrome was seen in 2 cases. In conclusion, flumazenil proved to be effective in the treatment of severe benzodiazepine intoxication. Beyond that, in cases of mixed overdosage or initially unknown diagnosis the antidote assisted in the clarification of the clinical condition.
