title: PHARMACOKINETICS OF DICLOFENAC SODIUM AND PAPAVERINE HYDROCHLORIDE AFTER ORAL ADMINISTRATION OF TABLETS TO RABBITS.
abstract: Non-compartmental pharmacokinetic analysis of diclofenac sodium (DIC) and papaverine hydrochloride (PAP) after oral administration of composed tablets to rabbits was developed. HPLC method for determination of DIC and PAP in rabbit plasma was developed and validated. Chromatographic separation of DIC, PAP and the IS was achieved on a Zorbax SB C18 5-µm column (150 mm x 4.6 mm) using methanol-water (55:45, v/v) as mobile phase at a flow rate of 0.8 mL/min. Pharmacokinetic analysis showed that oral administration of a tablet composed of DIC and PAP do not change the pharmacokinetic parameters such as MRT, MAT, Cl and bioavailability of the active substances compared with single administration of DIC and PAP after single dose.
