diazepam injection, USP - CARPUJECT Clinical Pharmacology

()

CLINICAL PHARMACOLOGY

In animals, diazepam appears to act on parts of the limbic system, the thalamus and hypothalamus, and induces calming effects. Diazepam, unlike chlorpromazine and reserpine, has no demonstrable peripheral autonomic blocking action, nor does it produce extrapyramidal side effects; however, animals treated with diazepam do have a transient ataxia at higher doses. Diazepam was found to have transient cardiovascular depressor effects in dogs. Long-term experiments in rats revealed no disturbances of endocrine function. Injections into animals have produced localized irritation of tissue surrounding injection sites and some thickening of veins after intravenous use.

Population PK analysis in 87 pediatric patients 0.4 – 17.8 years of age with status epilepticus showed that, after initial dosing, the median plasma half-life was 0.5 hours and the median terminal elimination plasma half-life was 18 to 25 hours.
