Benzathine Penicillin Sodium is a long-acting form of penicillin G, which exerts its bactericidal action by inhibiting the biosynthesis of bacterial cell wall peptidoglycan during the active multiplication stage of susceptible microorganisms. This inhibition leads to an osmotically unstable cell wall, resulting in cell lysis and bacterial death. However, it is not effective against penicillinase-producing bacteria or organisms with altered penicillin-binding proteins.
Benzathine Penicillin Sodium for Injection is indicated for the treatment and prophylaxis of various infections caused by penicillin-sensitive microorganisms, including:
Benzathine Penicillin Sodium for Injection is administered via intramuscular injection only. The dosage and frequency depend on the specific condition being treated:
Benzathine Penicillin Sodium for Injection should be stored in a refrigerator at a temperature between 2°C to 8°C (36°F to 46°F) to maintain its stability and efficacy. It should not be frozen.
