RESUMO
Oral dispersible tablets (ODTs) are patient compliant dosage forms which rapidly disintegrate in the mouth following active absorption with rapid onset of action. The current study was designed to resolve compression problems used for ODTs, as high compression force exhibited hardness and drug release problems. Formulations, F1-F9 were compressed at three different forces 44, 54 and 64 kN using cross-carmellose sodium (CCS) and sodium starch glycolate (SSG) and evaluated for pre and post compression. Formulations F1, F4 and F7 which were compressed at 44 kN showed hardness ranges between 5.09-6.15 with lowest DT (less than 15 s) and better LTZ release. While F2, F5 and F8 (compressed at 54 kN) demonstrated hardness in between 6.90-7.02. Similarly, F3, F6 and F9 compressed at 64 kN showed hardness values between 8.70-8.98 with increased DT and slow LTZ release. Friability results for all the formulations were within United States Pharmacopeial (USP) specifications (<1%). All formulations depicted t-test value <0.5, hence it found that all formulations showed significant statistical value within limits, however best compression force 44 kN showed low p value. It was concluded that optimized compression force for ODTs was 44 kN among all employed forces that exhibited desirable drug release.
