Mode of Action LEXIN 500mg

Cefalexin, the active component of LEXIN 500 mg, acts by inhibiting bacterial cell wall synthesis. It binds to specific proteins known as penicillin-binding proteins (PBPs) inside the bacterial cell wall. This action disrupts the construction of the cell wall, causing it to weaken and eventually rupture.

• Mechanism: Inhibits the cross-linking of peptidoglycan strands in bacterial cell walls
• Effect: Bactericidal (kills bacteria)
• Spectrum: Effective against Streptococcus, Staphylococcus, E. coli, Proteus mirabilis, Klebsiella

It does not work against viral infections like the common cold or flu.
