The disintegration times of six tablets per brand were determined in distilled water at (37.0 ± 0.5) °C using the British Pharmacopoeia (BP) disintegration tester (Mk IV, Manesty Machines, UK). The apparatus is an assembly of tubes covered at the lower end with a No. 10 mesh of 2 mm diameter and opened at the upper end. The whole assembly of tubes is then immersed inside a 1 L beaker containing 900 mL of distilled water. The beaker was placed inside the water bath and maintained at a constant temperature of (37.0 ± 0.5) °C. The tubes were made to oscillate at a constant rate, that at the upward stroke about 2.5 mL of the tubes were immersed in the medium and at the downward stroke, the tube went deep inside the medium leaving about 2.5 mL portion of the tube. The time taken for all the 6 tablets to break up into granules that were able to pass through the mesh was noted as the disintegration time. The test was repeated to obtain the average disintegration time. The SD were calculated.
