Cyprodenate is an old antidote for benzodiazepene overdose:
It is a relatively rare drug that doesn’t have a single aromatic ring – steroids are the broad class of exceptions that come to mind. It looks like this is some sort of cholinergic compound, but that’s just an educated guess. Doesn’t look like anyone uses it anymore, except some of the “smart drugs” crowd. Anyone know anything about it?
