Design, formulation, and evaluation of dexlansoprazole oral thin films
Abstract
Dexlansoprazole is a proton-pump inhibitor and was used in the treatment of gastric acid disorders. Dexlansoprazole oral thin films are fast dissolving films and are a new, patient-friendly, and more convenient formulation of dexlansoprazole, which can be taken with or without water. It disintegrates rapidly in the mouth and is swallowed easily with the patient’s saliva. This is an improved alternative formulation for all patients and offers the benefit of an alternative choice of administration of dexlansoprazole. This article deals with the formulation and evaluation of dexlansoprazole oral thin films (OTFs). The main objective of this study was to study the effect of combination of synthetic polymer [Hydroxypropyl methyl cellulose (HPMC15CPS)] and natural polymers (carrageenan / pectin / Maltodextrin) on the film forming properties and dissolution rate of the drug. The films were prepared by solvent casting method, using natural and synthetic film forming polymers in different concentrations; PEG 400 is used as plasticizer, aspartame and vanilla flavor as artificial sweetener and artificial flavor respectively. The prepared films were evaluated for weight uniformity, film thickness, folding endurance, dispersion test, drug content, and in vitro dissolution studies to ensure the physical stability of films. The formulation F12 with (HPMC15CPS: carrageenan: pectin in the ratio of 2:1:1 respectively) has physicochemical, mechanical properties. F12 films exhibits lower values…
