 Amiphenazole

Amiphenazole (Daptazile) is a respiratory stimulant traditionally used as an antidote for barbiturate or opiate overdose, usually in combination with bemegride, as well as poisoning from other sedative drugs and treatment of respiratory failure from other causes.It was considered particularly useful as it could counteract the sedation and respiratory depression produced by morphine but with less effect on analgesia.
