Description
Description
Benzathine Penicillin, a long-acting antibiotic, exerts its bactericidal effect by inhibiting the synthesis of bacterial cell walls. It specifically targets penicillin-binding proteins (PBPs) in susceptible bacteria, such as Streptococcus and Staphylococcus species. Benzathine Penicillin binds to PBPs, preventing the cross-linking of peptidoglycan chains, which are essential for maintaining the structural integrity of the bacterial cell wall. This interference leads to the weakening and eventual rupture of the cell wall, resulting in bacterial cell lysis and death. The unique characteristic of benzathine penicillin is its slow absorption and sustained release from the injection site, providing prolonged therapeutic levels of the drug in the bloodstream, allowing for less frequent dosing and ensuring effective treatment of certain infections.
