Relative Bioavailability Study Of Two Lincomycin Hydrochloride Hard Gelatinous Capsule
Relative Bioavailability Study Of Two Lincomycin Hydrochloride Hard Gelatinous Capsule 500 Mg Formulations, In Healthy Volunteers Using Formulations (Frademicina®) Manufactured By Pfizer Laboratories Ltd
To assess the relative bioavailability of two different batches of Frademicina® drug product, containing 500 mg lincomycin hydrocloride, manufactured by Pfizer Laboratories Ltd. The formulations' comparative bioavailability after oral administration will be assessed based on the statistical comparisons of the relevant pharmacokinetic parameters, obtained from the drug concentrations in the blood. The lincomycin hydrocloride concentration will be measured by a proper and validated analytical method.
