Procaine benzylpenicillin
（重定向自Procaine penicillin）
Procaine benzylpenicillin (rINN), also known as procaine penicillin, is an antibiotic useful for the treatment of a number of bacterial infections.
It is a form of penicillin which is a combination of benzylpenicillin and the local anaesthetic agent procaine. Following deep intramuscular injection, it is slowly absorbed into the circulation and hydrolysed to benzylpenicillin — thus it is used where prolonged low concentrations of benzylpenicillin are required.
