Description
A synthetic tetracycline derivative with similar antimicrobial activity. Animal studies suggest that it may cause less tooth staining than other tetracyclines. It is used in some areas for the treatment of chloroquine-resistant falciparum malaria (malaria, falciparum). PubChem (source: Drug Bank)
Indication
For the treatment of infections caused by susceptible organisms. (source: Drug Bank)
ATC Therapeutic Categories
- A01AB:Antiinfectives and antiseptics for local oral treatment
- J01AA:Tetracyclines
Pharmacology, Interactions, and Contraindications
Mechanism Of Action
Doxycycline, like minocycline, is lipophilic and can pass through the lipid bilayer of bacteria. Doxycycline reversibly binds to the 30 S ribosomal subunits and possibly the 50S ribosomal subunit(s), blocking the binding of aminoacyl tRNA to the mRNA and inhibiting bacterial protein synthesis. (source: Drug Bank)
Pharmacology
Doxycycline, a long-acting tetracycline derived from oxytetracycline, is used to inhibit bacterial protein synthesis and treat non-gonococcal urethritis and cervicitis, exacerbations of bronchitis in patients with COPD, and adult periodontitis. (source: Drug Bank)
