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.
