4.3 Drug Indication

Oxytetracycline is indicated for treatment of infections caused by a variety of Gram positive and Gram negative microorganisms including Mycoplasma pneumoniae, Pasteurella pestis, Escherichia coli, Haemophilus influenzae (respiratory infections), and Diplococcus pneumoniae.


5 Pharmacology and Biochemistry
5.1 Pharmacology

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.

Osol, A. and J.E. Hoover, et al. (eds.). Remington's Pharmaceutical Sciences. 15th ed. Easton, Pennsylvania: Mack Publishing Co., 1975., p. 1142


The serum half-life of oxytetracycline is 6 to 10 hours in adults with normal renal function and is reported to be 47 to 66 hours in patients with severe renal impairment. In patients with normal renal function, approximately 60 to 70 percent of a single oral dose of oxytetracycline is excreted in urine within 72 hours as active drug.

McEvoy, G.K. (ed.). American Hospital Formulary Service - Drug Information 92. Bethesda, MD: American Society of Hospital Pharmacists, Inc., 1992 (Plus Supplements 1992)., p. 319


A two-way crossover study was conducted in crossbred male calves (6-8 months old) to determine the bioavailability, pharmacokinetics and dosage regimens for a long-acting formulation of oxytetracycline (OTC-LA). The half-lives of oxytetracycline after intravenous and intramuscular administration were 7.8 hr and 24 hr, respectively. ....

PMID:10066127 Kumar R, Malik JK; Vet Res Commun 22 (8): 533-44 (1998)


The pharmacokinetic properties of oxytetracycline were studied following a single injection of a long-acting formulation (20 mg/kg body weight) into the semimembranosus muscle of healthy dogs and of dogs that had been experimentally infected with Ehrlichia canis. ... The mean apparent elimination half-life (t(1/2) beta) was significantly increased following infection. ... The absorption half-life (t(1/2) ab) was significantly decreased after infection.

5.7 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.


Tetracyclines inhibit bacterial protein synthesis by binding to the 30 S bacterial ribosome and preventing access of aminoacyl tRNA to the acceptor (A) site on the mRNA-ribosome complex. They enter gram-negative bacteria by passive diffusion through the hydrophilic channels formed by the porin proteins of the outer cell membrane, and active transport by an energy-dependent system that pumps all tetracyclines across cytoplasmic membrane. Although permeation of these drugs into gram-positive bacteria is less well understood, it also is energy requiring. At high concn, these cmpd impair protein synthesis in mammalian cells. However, because mammalian cells lack the active transport system found in bacteria, and the ribosomal target is less sensitive, tetracyclines are selectively active against bacteria. /Tetracyclines/
