The therapeutic as well as adverse effects of midazolam are due to its effects on the GABA A receptors; midazolam does not activate GABA A receptors directly but, as with other benzodiazepines, it enhances the effect of the endogenous neurotransmitter GABA on the GABA A receptors (increasing the frequency of Cl − channel opening) resulting in ...
Midazolam 1 & 5 mg/mL injections (Canada). Benzodiazepines possess psycholeptic, sedative, hypnotic, anxiolytic, anticonvulsant, muscle relaxant, and amnesic actions, [4] [5] which are useful in a variety of indications such as alcohol dependence, seizures, anxiety disorders, panic, agitation, and insomnia.
Variation in potency of certain effects may exist amongst individual benzodiazepines. Some benzodiazepines produce active metabolites . Active metabolites are produced when a person's body metabolizes the drug into compounds that share a similar pharmacological profile to the parent compound and thus are relevant when calculating how long the ...
Due to these contraindications and the possibility of it causing severe adverse effects including seizures, adverse cardiac effects, and death, [50] [51] in the majority of cases there is no indication for the use of flumazenil in the management of benzodiazepine overdose as the risks in general outweigh any potential benefit of administration.
A study into the effects of the benzodiazepine receptor antagonist, flumazenil, on benzodiazepine withdrawal symptoms persisting after withdrawal was carried out by Lader and Morton. Study subjects had been benzodiazepine-free for between one month and five years, but all reported persisting withdrawal effects to varying degrees.
NMDA receptor antagonists induce a state called dissociative anesthesia, marked by catalepsy, amnesia, and analgesia. [1] Ketamine is a favored anesthetic for emergency patients with unknown medical history and in the treatment of burn victims because it depresses breathing and circulation less than other anesthetics.
Amnesia is desirable during surgery, so general anaesthesia procedures are designed to induce it for the duration of the operation. Sedatives such as benzodiazepines, which are commonly used for anxiety disorders, can reduce the encoding of new memories, particularly in high doses (for example, prior to surgery in order for a person not to recall the surgery).

Celexa – an antidepressant of the SSRI class; Centrax – an anti-anxiety agent; Clozaril – atypical antipsychotic used to treat resistant schizophrenia; Concerta (methylphenidate) – an extended release form of methylphenidate
