Pharmacokinetics The drug was absorbed quickly and completely by intramuscular injection. The bioavailability was 91.9% in pigs and 82% in cows. It is widely distributed in animals and can enter tissues and body fluids well. Except cerebrospinal fluid, the concentration of drugs in almost all tissues is higher than that in plasma. The main hepatic metabolism is the removal of the ethyl of the 7-piperazine ring to produce ciprofloxacin, followed by oxidation and glucuronic acid binding. Mainly through the kidney (renal tubular secretion and glomerular filtration) discharge, 15% ~ 50% in the original form from the urine. The elimination half-life of intramuscular injection was 5.9 hours in dairy cows, 1.5 ~ 4.5 hours in sheep, and 4.6 hours in pigs.
