Abstract: Bioavailability studies using urinary excretory data have been carried out. Paracetamol tablets from a Ghanaian Pharmaceutical Manufacturing Company were adequately identified quantified and their pharmaceutical equivalence with respect to a reference established. The fraction of dose excreted unchanged in urine by the test and reference samples, and the Relative Bioavailability of the test sample was determined using a crossover design. 1 000mg each of the test and reference samples were administered to the subjects in a lasting state, with a washout period of one week between drug administrations. Urine samples were collected and analysed at specified time intervals, spanning 24 hours. The analytical method employed was RP-LC with a stationary phase of Spherisord S5ODS I Phase Sep column and a mobile phase combination of Methanol, Water nd Glacial Acetic Acid in the ratio: 2$: 69: 3 respectively. Column eluate was monitored at 236nm a U V detector. The analysis was conducted at an ambient temperature with a flow rate of l.5ml/min. and 0.5AUFS. The mean percentage amounts of paracetamol excreted unchanged in urine was found to be 10.521 % and 10.691% 1br the test and reference samples respectively. The Relative Bioavailability of the test sample was found to be 98.41 % which is within the WI l( range of 80% to 1 25%. The determined means and standard deviations were statistical l compared and found not to differ significantly. The test and reference samples were found to be pharmaceutically equivalent, Bioequivalent and therapeutically equivalent. They are therefore interchangeable for therapeutic purposes.
