Pharmacology
The bioavailability of ofloxacin in the tablet form is approximately 98% following oral administration reaching maximum serum concentrations within one to two hours. Between 65% and 80% of an administered oral dose of ofloxacin is excreted unchanged via the kidneys within 48 hours of dosing. Therefore elimination is mainly by renal excretion. However, four to eight percent of an ofloxacin dose is excreted in the feces. This would indicate a small degree of biliary excretion as well. Plasma elimination half-life is approximately 4 to 5 hours in patients and approximately 6.4 to 7.4 hours in elderly patients.
