Drug Isomer

Drug isomers are compounds with the same molecular formula but different atomic arrangements or spatial configurations. They are divided into structural isomers and stereoisomers, and have different biological activities, safety and metabolic characteristics. Drug isomers can be used as drug improvement groups or drug efficacy control groups. For example, Carvedilol has higher bioavailability and better safety than (R)-Carvedilol.
