Formulation Design and Optimization of Orodispersible Tablets of XXXX by Sublimation Method.

@entity1 @entity3358 @entity1089 @entity9679
The objective of present study was to formulate directly compressible orodispersible tablets of @entity1089 by sublimation method with a view to enhance @entity1 compliance. A full 3(2) factorial design was used to investigate the effect of two variables viz., concentration of Indion 414 and @entity9679 . Indion 414 (3-5 % w/w) was used as superdisintegrant and @entity9679 (5-15 % w/w) as subliming agent. The tablets were evaluated for thickness, weight variation, @entity3358 , friability, content uniformity, wetting time, porosity, in vitro disintegration time and in vitro drug release. The formulation containing 5% w/w of Indion 414 and 5% w/w @entity9679 was emerged as promising based on evaluation parameters. The disintegration time for optimized formulation was 18.66 s. The tablet surface was evaluated for presence of pores by scanning electron microscopy before and after sublimation. Differential scanning colorimetric study did not indicate any drug excipient incompatibility, either during mixing or after compression. The effect of independent variables on disintegration time, % drug release and friability is presented graphically by surface response plots. Short-term stability studies on the optimized formulation indicated no significant changes in drug content and in vitro disintegration time. The directly compressible orodispersible tablets of @entity1089 fumarate with lower friability, greater drug release and shorter disintegration times were obtained using Indion 414 and @entity9679 at optimum concentrations.
