Quinidine phenylethyl barbiturate is a little-known compound classified as a cinchona alkaloid [1]. There is limited information available about this specific substance, though some resources suggest it might be a combination of quinidine and a phenylethyl barbiturate, likely phenobarbital [1, 2, 3].
- Quinidine: This is a medication previously used to treat heart arrhythmias. It has since been largely replaced by other medications due to its potential side effects [4].
- Phenobarbital: This is a medication that can be used to treat seizures and for short-term relief of anxiety [5]. It is a central nervous system depressant, which means it slows down brain activity.
