Formulation and Evaluation of Orodispersible Tablet of Atorvastatin Calcium by Using Hibiscus rosa sinesis Mucilage as Natural Superdisintegrant

Abstract

Orodispersible tablets (ODTs), also known as fast melt, quick melts, fast disintegrating have the unique property of disintegrating in the mouth in seconds without chewing and the need of water. Oral bioavailability of Atorvastatin Calcium is low (14%) and shows extensive intestinal clearance and first-pass metabolism, which is the main cause for the low systemic availability. In the present work, orodispersible tablets of Atorvastatin calcium were prepared by direct compression method using Hibiscus rosa sinesis mucilage as natural superdisintegrant with a view to enhance patient compliance and to avoid hepatic first pass metabolism and to improve its bioavailability. The prepared batches of tablets were evaluated for hardness, friability, drug content uniformity, wetting time, water-absorption ratio and in-vitro dispersion time. Short-term stability studies on the promising formulation indicated that there are no significant changes in drug content and in vitro dispersion time.
