Figs. 3(a) and 3(b) represent the dissolution profiles of normal and effervescent mixed fruit powder tablets,
respectively. They were obtained by plotting percent dissolved against time. The normal mixed tablets showed
different dissolution rates versus time when it was dissolved in the two different dissolution mediums. The simulated
saliva resulted in a faster dissolution rate as it required less total dissolution time compared to dissolution in water.
Dissolution in simulated saliva fluid required 100 min whereas dissolution in the distilled water took 120 min. The
dissolution profiles showed that during the first 20 min in both dissolution media more than 40 percent dissolution
had occurred. This rate decreases with time steps, as with increasing time the dissolution media becomes more
saturated which reduces mass transfer from solid tablet to liquid medium.
