🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by inhibiting bacterial cell wall synthesis. It binds to penicillin-binding proteins (PBPs) on the inner membrane of susceptible bacteria, blocking the cross-linking of peptidoglycan chains. This weakens the cell wall, leading to bacterial cell lysis and death. It is bactericidal against a range of Gram-positive and some Gram-negative bacteria.

Strength: Dry syrup for oral suspension, 250 mg/5 ml after reconstitution.
