OBJECTIVE:To optimize the matrix formulation of cataplasm used to cure infantile diarrhea.
METHODS:The optimum proportion of matrix for the preparation technology process of cataplasm was selected by uniform design and SPSS regression analysis. A check-up for adhibition , peeling strength, nonflowing, content of cream was founded.
RESULTS:The best matrix's prescription gelatin: CMC-Na: PANA: kaolin: aluminum trichloride: citric acid: PVP K-30: PEG400: trimethylene glycol: tween-80 was 0.25 : 0.1 : 0.2 : 1.5 : 0.4 : 0.6 : 0.8 : 2 : 1 : 0.5.
CONCLUSION:The preparation technique of cataplasm is feasible, and its quality is steerable, it is a safe and effective transdermal-drug delivery system.
