Indications & Uses

Pharmacology

Oxytetracycline works by blocking bacterial protein synthesis: it binds reversibly to the 30S ribosomal subunit and stops amino-acyl tRNA from attaching to the ribosome's A site, halting cell growth. Being lipophilic, it crosses the bacterial cell membrane easily, and it can also slip through passively via the membrane's porin channels.

Contraindications

Oxytetracycline must not be given to anyone with a known hypersensitivity to tetracyclines. It is also not suitable for children under 12 years of age. The medicine is contraindicated in pregnancy, as it can cause staining of the developing baby's teeth and may affect growth.

Pregnancy & Breastfeeding

Results of animal studies show that tetracyclines cross the placenta, reach fetal tissues, and can be toxic to the developing fetus. Animals treated early in pregnancy have also shown evidence of embryotoxicity. In humans, tetracyclines pass into the breast milk of mothers taking a drug from this class.
