Variation concentration effect of propyleneglycol, glycerin, and polyethyleneglycol 400 to physical properties and dissolution rate of loratadine liquisolid tablet.

OBJECTIVES This study aimed to evaluate the variation concentration effect of propyleneglycol, glycerin, and polyethyleneglycol 400 as a nonvolatile solvent on the physical properties and dissolution rate of the loratadine liquisolid tablet. METHODS The tablet was formulated into 10 formulas, where nine were liquisolid and one was conventional (CT). The concentration of propyleneglycol, glycerin, and polyethyleneglycol used in liquisolid tablets were 14, 15, and 16%. Furthermore, the mixture was evaluated based on flow properties and compressibility index. The tablet was evaluated based on hardness, friability, disintegration time, and dissolution, and the data obtained was evaluated with ANOVA or Kruskal-Wallis statistic program. RESULTS The result showed that flow properties, disintegration time, and dissolution have a significant value less than 0.05. The tablet friability for all concentration solvents, hardness at 14 and 15% solvent concentration, and compressibility index at 15 and 16% have significant value more than 0.05. The 16% propyleneglycol type solvent concentration tablet has the physical properties and contains the best solution. CONCLUSIONS From the result, it is reasonable to conclude that F7 is the tablet with all the physical properties and the best dissolution.
