THE INFLUENCE OF MAGNESIUM STEARATE, PURIFIED TALC AND COMBINATION OF BOTH ON TERNARY/QUATERNARY INTERACTIVE MIXTURE OF FREELY AND POORLY WATER-SOLUBLE DRUG
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2015, Vol 7, Issue 1
Abstract
Objective: This research purposed to describe and evaluate the influence of magnesium stearate (MgSt), purified talc (talc) and combination of both (MgSt-PT) on ternary/quaternary mixture of freely and poorly water-soluble drug.Methods: Chlorpheniramine maleate (CPM) and prednisone (PDN) were used as the drug model of freely and poorly water-soluble drug, respectively. Compatibility studies between drugs and lubricants were carried out using Fourier transform infrared spectroscopy (FTIR). Ternary/quaternary interactive mixture of drugs, lubricants and carriers were conducted using granules of lactose-starch (1:1) as carriers with particle size 250 – 425 µm. Characterizations were conducted by homogeneity of mixture, physical properties of granules and tablets and drug releases. The results were analyzed statistically using one-way analysis of variance (ANOVA) with 95% of confidence interval level and dependent method for drug release.Results: Homogeneity of binary mixture within drug and carrier was achieved in 60 minutes with 20 revolutions per minute. MgSt, talc and combination of both provided stable ternary/quaternary interactive mixture. MgSt affected the reduction of compactibility, prolong the disintegration time, retardation the drug release and talc improved flowability.Conclusion: Talc provided more preferable effects than MgSt, and combination of both lubricants showed desirable physical properties of tablet. MgSt, talc and combination of both provided no significant effect on physical properties and drug release of CPM as freely water-soluble drug and the significant effect was observed on PDN as poorly water-soluble drug.
