🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by binding to the 50S ribosomal subunit of susceptible bacteria, thereby inhibiting bacterial protein synthesis. This action prevents the bacteria from growing and multiplying, which allows the body's immune system to clear the infection. It is generally bacteriostatic but can be bactericidal at higher concentrations against certain organisms.
