Nayan N. Vadsola* and Bijal Prajapati
Abstract
The aim of present work was to formulate and evaluate mouth
dissolving tablet of Bambuterol Hydrochloride to minimize the
disintegration time and improve % drug release. Bambuterol
Hydrochloride is an Antiasthmatic drug. Mouth dissolving tablet was
formulated using Camphor as a subliming agent. Sodium deoxycholate
and Cross povidone were added as permeation enhancer and as a
super-disintegrant respectively. Optimization was done by 32 full
factorial design and developed formulation was evaluated for In-vitro
drug release study and Ex-vivo diffusion study. Concentration of
Camphor and Sodium deoxycholate were selected as independent
variables. All formulations were evaluated for properties such as
weight variation, hardness, friability, drug content, disintegration time, wetting time study,
In-vitro dissolution study, Ex-vivo diffusion study. % In-vitro drug release and % Ex-vivo
permeation at 10 min were selected as dependent variables. Analysis of variance was
performed for dependent variables. In-vitro release data was fitted to various kinetic models
of drug release. Optimized formulation batch (B9) had complies the acceptance criteria and
was found to be stable for 1 month. % In vitro drug release and % ex-vivo permeation of
optimized formulation were found to be 90% and 78.46% at 10 min respectively.
Keywords: Antiasthmatic drug, Super-disintegrating agent, Sublimation method, Mouth dissolving tablet, 32 full factorial designs.
