Formulation and Evaluation of Mouth Dissolving Tablet of Almotriptan Malate

Abstract

Mouth dissolving tablet disintegrates and dissolves rapidly in the saliva, within a few seconds without the need of drinking water or chewing. A mouth dissolving tablet usually dissolves in the oral cavity within 15 seconds to 3 minutes. Almotriptan malate is an anti migraine drug with bitter taste and shows hepatic metabolism. In the present work, Mouth dissolving tablets of almotriptan malate were prepared by direct compression method using sodium starch glycolate and croscarmellose sodium as superdisintegrant with a view to enhance patient compliance and to avoid gastric dysmotility which is common with migraine drugs and for fast action of drug. 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 disintegration time.
