Formulation and Evaluation of Sublingual Tablets of Meclizine Hydrochloride

Abstract

The aim of the present research is to formulate sublingual tablet of Meclizine Hydrochloride using direct compression method. Moreover the purpose of developing this dosage form is to provide rapid onset of action beneficial in managing conditions of nausea, vomiting and vertigo, and also overcome the problems of solubility of drug by inclusion complexes. The disease like nausea and vomiting required fast onset of action which is necessary for the fast pharmacological action. So, the sublingual route of administration were better way of medication and overcome the problems like dysphagia. The Meclizine hydrochloride is histamine H1 receptor antagonist with antiemetic and antivertigo properties. The oral bioavailability is low (25%), with low solubility (BCS class 2 drug), and metabolized by Hepatic CYP2D6 enzyme by the process of hepatic hydroxylation. Sublingual tablet of antiemetic drug meclizine hydrochloride will be prepared by direct compression method. The Solubility of sublingual tablets will be enhanced by Inclusion complexes. These are prepared by weighed amount of drug mixed with β-cyclodextrin in different dose ratios [1:1,1:2] was wetted with small drops of water to form kneaded like paste and triturated in mortar pestle for several hours resulting in evaporation of solvent. The inclusion complexes was collected and dried for 48 hours and pulverized using mortar and pestle and then sieved through mesh #60. Then properly mixed with other excipients in polybag for 1 hour. The powder like complex was used for further evaluation studies and to form sublingual tablets by direct compression method.
