Nordazepam (INN; marketed under brand names Nordaz, Stilny, Madar, Vegesan, and Calmday; also known as nordiazepam, desoxydemoxepam, and desmethyldiazepam) is a 1,4-benzodiazepine derivative.

[5] Nordazepam is a partial agonist at the GABAA receptor, which makes it less potent than other benzodiazepines, particularly in its amnesic and muscle-relaxing effects.

[6] Its elimination half life is between 36 and 200 hours, with wide variation among individuals; factors such as age and sex are known to impact it.

[7] This can be attributed to extremely variable hepatic and renal metabolic functions among individuals depending upon a number of factors (including age, ethnicity, disease, and current or previous use/abuse of other drugs/medicines).

[9] In case of serious medical reasons, nordazepam can be given in late pregnancy, but the fetus, due to the pharmacological action of the drug, may experience side effects such as hypothermia, hypotonia, and sometimes mild respiratory depression.
