Doxycycline hydrochloride

Doxycycline hydrochloride

Doxycycline is a tetracycline broad-spectrum antibiotic. Its mechanism of action is to specifically bind to the site A of the 30S subunit of the bacterial ribosome, inhibit the growth of the peptide chain and affect the synthesis of bacterial proteins. It is a broad-spectrum bacteriostatic agent and has a bactericidal effect at a high concentration.

Doxycycline is more effective against Gram-positive bacteria than Gram-negative bacteria, but it is ineffective to Enterococci (with drug resistance). Other strains such as Actinomycetes, Bacillus anthracis, Listeria monocytogenes, Clostridium, Nocardia, Vibrio, Brucella, Campylobacter, and Yersinia are sensitive to this product.
