Abstract
Objective: A natural gum from Vateria indica was investigated as a novel matrix-forming material for sustained drug delivery using diclofenac potassium as a model drug.Methods: In the current investigation, we formulated a matrix tablet using chloroform soluble gum portion of Vateria indica modified gum (VIMG) as a natural matrix-forming agent. It was used with a drug-polymer ratio ranging from 1:0.5 to 1:4.5. The pre-compression study of the powder blends was done by calculating bulk density, tapped density, angle of repose, and carr’s index, compressibility, and hausner’s ratio. The tablets were prepared by direct compression method and prepared tablets were evaluated and were found according to the official guidelines by pharmacopeia. The in vitro drug release was carried out using USP paddle type II apparatus and the release was found to be sustained.Results: The formulation VIMG-5 containing drug: polymer ratio 1:2.5 showed the 96.26%±1.73 drug release in 12 h. The results showed that chloroform soluble fraction of Vateria indica can be used as a drug release modifier to delay the rate of drug release, which depended on the amount of gum composition, as the concentration of gum was increased, there was sustained the drug release with promising accelerated stability.Conclusion: The evaluation studies on sustained release matrix tablets using Vateria indica chloroform soluble portion of gum as natural material demonstrate the multivariate applications such as matrix forming, binder, and release retardant of the gum in tablet formulation.
