Benzathine Penicillin Injectable, a long-acting β-lactam antibiotic, inhibits bacterial cell wall synthesis to target Gram-positive pathogens like group A streptococci and syphilis-causing Treponema pallidum. Administered via deep IM injection, it releases slowly to maintain therapeutic levels for 2-4 weeks, making it ideal for treating syphilis (2.4 million units weekly for 2-3 weeks) and preventing rheumatic fever (1.2 million units monthly). Key risks include allergic reactions (mandatory skin test) and local pain from its low solubility, while the Jarisch-Herxheimer reaction may occur in syphilis treatment. Stored at ≤20ºC, this prescription drug is a cornerstone in syphilis management and rheumatic fever prophylaxis, requiring strict clinical monitoring and professional administration.
Regular RPR titer checks during syphilis treatment to assess efficacy.
Pregnancy & Lactation:
The only effective drug for treating syphilis in pregnant women, used under medical guidance to prevent congenital syphilis.
