ABSTRACT:
The aim of present work is to prepare the orally dissolving tablets of poorly soluble Ondransetron Hydrochloride as its soluble form by adopting complexation method using different superdisintegrants alone and in combination. The growing importance of orally dissolving tablet was underlined recently when European Pharmacopoeia adopted the term “Oro dispersible tablet” as a tablet that to be placed in the mouth where it disperses rapidly before swallowing. Their characteristic advantages such as administration without water anywhere, anytime lead to their suitability to geriatric and paediatric patients. The complex prepared was showed better solubility in simulated salivary PH of 6.8. The pre compression characteristics of drug, drug with Beta cyclodextrin and final blend were evaluated with respect to standards. Results of the study showed that the optimized tablet with combination of superdisintegrants (2.5% crosspovidone, 3.5% sodium starch glycolate) showed hardness of 3.5Kg/Cm2, thickness 2.10mm, wetting time 18 sec, drug content 99.15%, disintegration time 20sec, in-vitro dispersion time 25sec, in-vitro drug release of 89.59% (in 3min) and percentage of drug permeation as 89.45% (in 5 min) and it is comparable with higher percentage of superdisintegrants used for tablet preparation. So this method was a promising approach for developing cost effective dosage form with high efficacy in treatment.
