I apologize for Googling up this answer and not knowing what I’m talking about, but I thought this was interesting.
Apparently, Distonocalm is a brand name for a mixture of drugs that isn’t commonly sold in English-speaking countries, so there’s no English equivalent.
According to this page, Distonocalm consists of atropine, propanolol, amobarbital and ergotamine.
Atropine is a parasympathetic antagonist, propanolol is a sympathetic antagonist (usually used as a blood-pressure medicine), amobarbital is a barbiturate and ergotamine is a vasoconstrictor used for treating migraines.
What does that combination do? My Romanian is a little rusty (I studied Spanish in high school), but I think it’s for calming down your digestive tract. It’s not a benzodiazepine, but amobarbital works on the same GABA-gated chloride channels that benzodiazepines do, so Distonocalm would probably have some kind of tranquilizing effect.
