Benzathine benzylpenicillin has the same antimicrobial action as benzylpenicillin which exerts its bactericidal action on growing and dividing bacteria by inhibiting bacterial cell wall synthesis. IM administration results in a prolonged effect, but because of its relatively low blood concentrations, its use should be restricted to microorganisms that are highly susceptible to it.

• Group-A beta-haemolytic streptococcal infections: 600,000 units as a single IM dose
• Prevention of rheumatic fever: 1.2 million units monthly IM injection
• Acute otitis media: 600,000 units as a single injection
• Early syphilis: 2.4 million units as a single dose
