Pharmacokinetics The intramuscular absorption of this product is rapid and complete, with a bioavailability of 91.9% in pigs and 82% in dairy cows. It is widely distributed in animals and can enter tissues well. Except cerebrospinal fluid, the concentration of drugs in almost all tissues is higher than that in plasma. The liver metabolism is mainly to produce ciprofloxacin by removing the ethyl of 7-piperazine ring, followed by oxidation and glucuronic acid binding. It is mainly excreted by the kidneys (by renal tubule secretion and glomerular filtration), and 15% to 50% is excreted from the urine in its original form. The elimination half-life varies greatly in different species and different routes of administration. The elimination half-life after intramuscular injection is 5.9 hours in cows, 1.5 to 4.5 hours in sheep, and 4.6 hours in pigs.
