Pharmacological particulars
Pharmacotherapeutic group: Antibacterial
ATC Vet Code: QJ01AA06
Pharmacodynamic properties
Oxytetracycline is a bacteriostatic antibiotic that inhibits protein synthesis in susceptible bacteria. Inside the cell it binds irreversibly to receptors on the 30S subunit of the bacterial ribosome where it interferes with the binding of the aminoactyl-transfer RNA to the acceptor site on the messenger RNA ribosome complex. This effectively prevents the addition of the amino acids to the elongating peptide chain, inhibiting protein synthesis.
The product is specifically formulated to provide a prolonged action, resulting in sustained antibacterial activity. Following intramuscular administration, effective blood levels persist for 3-4 days at a dose rate of 20mg/kg and for 5-6 days at a dose rate of 30mg/kg. Maximum blood levels are achieved between 4-6 hours following administration.
