🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Clarithromycin inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, specifically to the 23S rRNA component. This binding blocks the translocation step of peptide chain elongation, preventing the addition of new amino acids to the growing peptide chain. As a result, bacterial growth is halted and the bacteria are eventually killed or their multiplication is suppressed.
