At the initial stage of the dissolution test, the dissolution chamber was filled with 500 ml dissolution medium and
checked for temperature of the dissolution medium. Then 5 tablets were placed into the chamber and the machine
paddle and stopwatch were switched on. A 25 ml sample was collected from the chamber after 1 minute and 20
minutes intervals for the effervescent fruit mixed tablet and the normal fruit mixed tablet, respectively. The samples
were kept in 50 ml centrifugal tubes for further analysis, while the chamber was filled with fresh dissolution
medium. A Ultra Violet spectrophotometer (HACH DR 2800, United State) was used to analyse the amount of
solutes in the samples collected from the dissolution chamber. Absorbance of light by the sample solutions was
measured at 560 nm wave length. The percent dissolution/solute release was calculated using the following
equation:
