Contraindications & Blackbox WarningsWith our commercial data, access important information on dangerous risks, contraindications, and adverse effects.Our Blackbox Warnings cover Risks, Contraindications, and Adverse Effects- Pharmacodynamics
Oxytetracycline is known as a broad-spectrum antibiotic due to its activity against such a wide range of infections. It was the second of the tetracyclines to be discovered. Oxytetracycline, like other tetracyclines, is used to treat many infections common and rare. Its better absorption profile makes it preferable to tetracycline for moderately severe acne, but alternatives sould be sought if no improvement occurs by 3 months.
- Mechanism of action
Oxytetracycline inhibits cell growth by inhibiting translation. It binds to the 30S ribosomal subunit and prevents the amino-acyl tRNA from binding to the A site of the ribosome. The binding is reversible in nature. Oxytetracycline is lipophilic and can easily pass through the cell membrane or passively diffuses through porin channels in the bacterial membrane.

Drug Interaction Integrate drug-drug
interactions in your softwareAcenocoumarol The risk or severity of bleeding can be increased when Oxytetracycline is combined with Acenocoumarol. Acetylcysteine The therapeutic efficacy of Acetylcysteine can be decreased when used in combination with Oxytetracycline. Acetylsalicylic acid The excretion of Oxytetracycline can be decreased when combined with Acetylsalicylic acid. Acitretin The risk or severity of pseudotumor cerebri and elevated intracranial pressure can be increased when Acitretin is combined with Oxytetracycline. Acyclovir The excretion of Acyclovir can be decreased when combined with Oxytetracycline. Adefovir dipivoxil The excretion of Adefovir dipivoxil can be decreased when combined with Oxytetracycline. Alitretinoin The risk or severity of pseudotumor cerebri and elevated intracranial pressure can be increased when Alitretinoin is combined with Oxytetracycline. Allopurinol The excretion of Allopurinol can be decreased when combined with Oxytetracycline. Almasilate Almasilate can cause a decrease in the absorption of Oxytetracycline resulting in a reduced serum concentration and potentially a decrease in efficacy. Alprostadil The excretion of Alprostadil can be decreased when combined with Oxytetracycline.
