Oxytetracycline hydrochloride inhibits bacterial protein synthesis by reversibly binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from attaching to the acceptor (A) site.
This bacteriostatic action disrupts peptide chain elongation, effectively controlling Gram-positive and Gram-negative bacteria, rickettsiae, chlamydia, mycoplasma, and protozoa.
Its lipophilic nature allows passive diffusion through bacterial membranes, enhancing efficacy against intracellular pathogens
