Beer’s calibration curve for paracetamol was obtained at a concentration range of 0.1 – 0.8 mg/ml in 0.1 N HCl at a predetermined wavelength of 245 nm. The in vitro dissolution profile for each batch of tablets was determined using the paddle method 15, with an Erweka DT 600 Dissolution apparatus. The dissolution medium consisted of 900 ml of freshly prepared 0.1 N HCl. The temperature of the medium was maintained at 37 + 1 oC. A tablet from each batch was placed inside a tightly secured basket and the basket was placed in the bottom of the beaker. The paddle was rotated at 100 rpm. At predetermined intervals, 5 ml sample was withdrawn from the dissolution medium, filtered with a non adsorbent filter paper (Whatman No. 1) and the filtrate was assayed using spectrophotometer (Jenway 6305, UK) at 245 nm. An equal volume of the withdrawn sample was replaced with a fresh medium to maintain sink condition. The amount of drug released at each time interval was determined with reference to the Beer’s plot for the drug.
