Benzylpenicillin clemizole salt is a modified salt form of benzylpenicillin (penicillin G) combined with clemizole to prolong its duration of action after intramuscular injection. This formulation allows slower absorption into the bloodstream, maintaining therapeutic antibiotic levels for an extended period compared to standard benzylpenicillin. It is used in the treatment of susceptible bacterial infections, particularly streptococcal infections, and may also be used in the prevention of rheumatic fever. Like other penicillin preparations, it works by inhibiting bacterial cell wall synthesis and may cause allergic reactions in penicillin-sensitive individuals.
