Release kinetics of salbutamol sulphate from wax coated microcapsules and tableted microcapsules.

Abstract

Microcapsules of salbutamol sulphate were prepared using beeswax and carnauba wax as coating materials. In vitro release kinetics were studied following the zero order, first order and Higuchi equations. Beeswax alone was not effective but beeswax and carnauba wax combinations were suitable in controlling the in vitro release of the drug. Microcapsules were… (More)
