🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine is a broad-spectrum tetracycline antibiotic. It enters susceptible bacteria and binds reversibly to the 30S ribosomal subunit, blocking the attachment of aminoacyl-tRNA to the mRNA-ribosome complex. This prevents the addition of amino acids to the growing peptide chain and stops bacterial protein synthesis. Because protein synthesis is essential for bacterial growth and multiplication, this medicine is primarily bacteriostatic at usual doses. It also has anti-inflammatory properties that contribute to its benefit in acne.
