What prescription drugs are barbiturates in and why are they banned in some countries?

NO BANNED CONTROLLED: Barbiturates can be found in anti seizure meds like Phenobarbital (not used as much now) and also in the headache meds fiorinal (aspirin butalbital and caffeine) and fioricet. I am unaware of them being actually banned. Th ey are highly controlled due to addvtive/abuse potential. Not a popular in use as in the past for anxiety and sleep. Quualudes are banned but hat is another category. It is just that there are newer safer meds.
