Indications & Uses
Tetraderm is indicated for:
Pharmacology
Oxytetracycline slows bacterial growth by blocking protein synthesis. It attaches to the 30S ribosomal subunit, stopping amino-acyl tRNA from reaching the ribosome's A site, and this binding is reversible. Because oxytetracycline is lipophilic, it crosses the cell membrane easily and can also diffuse passively through porin channels in the bacterial membrane. This ointment's broad-spectrum action against both gram-positive and gram-negative organisms is strengthened by polymyxin B, which works particularly well against gram-negative infections, especially those caused by Pseudomonas aeruginosa, where it is considered the antibiotic of choice. Polymyxin B sulfate also shows some antifungal activity.
