🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by binding to the 50S ribosomal subunit of susceptible bacteria, thereby inhibiting protein synthesis. This action is primarily bacteriostatic, but it can be bactericidal at higher concentrations. By blocking the production of essential proteins, it prevents bacterial growth and multiplication, allowing the body's immune system to eliminate the infection.
