General supportive measures should be employed, along with intravenous fluids, and an adequate airway maintained. Hypotension may be combated by the use of norepinephrine or metaraminol. Dialysis is of limited value. Flumazenil (Anexate) is a competitive benzodiazepine receptor antagonist that can be used as an antidote for benzodiazepine overdose. In particular, flumazenil is very effective at reversing the CNS depression associated with benzodiazepines but is less effective at reversing respiratory depression. Its use, however, is controversial as it has numerous contraindications. It is contraindicated in patients who are on long-term benzodiazepines, those who have ingested a substance that lowers the seizure threshold, or in patients who have tachycardia or a history of seizures. As a general rule, medical observation and supportive care are the mainstay of treatment of benzodiazepine overdose. Although benzodiazepines are absorbed by activated charcoal, gastric decontamination with activated charcoal is not beneficial in pure benzodiazepine overdose as the risk of adverse effects often outweigh any potential benefit from the procedure. It is recommended only if benzodiazepines have been taken in combination with other drugs that may benefit from decontamination. Gastric lavage (stomach pumping) or whole bowel irrigation are also not recommended.

Camazepam has been shown to bind competitively to benzodiazepine receptors in the brain with a relatively low affinity in animal models. This binding of benzodiazepine receptors by camazepam and its active metabolites is responsible for its anticonvulsant effects. Notably, only three metabolites were shown to exert anticonvulsant activity, temazepam, oxazepam, and hydroxy camazepam. The anxiolytic properties of camazepam are also attributed to their ability to bind benzodiazepine receptors, also known as GABA receptors. When benzodiazepines bind to GABA receptors they increase the efficiency with which the inhibitory neurotransmitter GABA binds.

Metabolized by the liver into more than 10 metabolites, some of which are also active and posses anticonvulsant properties. [3] One active metabolite of note is temazepam which has roughly equal in effectiveness as an anxiolytic, but is less anticonvulsant, sedating, and motor-impairing. Camazepam undergoes enantioselective metabolism by human liver microsomes. [1]
