Dissolution of the mixed fruit tablets was carried out by observing kinetics
of erosion of tablets in three different solvents as described in Adiba
et al. [4]. Distilled water, 0.1 N hydrochloric acid solution and citrate buffer
of pH 4 were used as solvents. Three mixed fruit tablet formulations,
first having no disintegrant agent (NSD), second with 1% effervescent
agent (EFA) (equal ratio of sodium bicarbonate and citric acid)
and third containing 1% Kollindon CL (KCL; polyvinypolypyrrolidone,
E-1202)were used to observe the erosion kinetics. Erosion testwas carried
out under controlled temperature (37 °C) till dissolution was completed.
The percentage of erosion was calculated using the following
equation:
