DEVELOPMENT AND EVALUATION OF ANTIDIABETIC POLYHERBAL TABLET USING MEDICINAL PLANTS OF TRADITIONAL USE

Abstract

The aim of the present study is to develop and evaluate polyherbal tablet prepared for the management of diabetes with enhanced disintegration time. The polyherbal extract prepared using methanolic extract of selected traditionally used medicinal plants such as Adenanthera pavonina, Kigelia africana, Parkia biglandulosa and Syzygium jambose (1:1:1:2) was evaluated in      alloxan monohydrate induced diabetic rat model. The polyherbal tablets were prepared by wet granulation method with excipients microcrystalline cellulose; dicalcium phosphate dehydrate and sodium starch glycolate. After preformulation studies, tablets were evaluated by using weight variation, hardness, friability and disintegration time. The diabetic rats treated with polyherbal extract were compared with the diabetic control rats group. Positive results were obtained in the observed parameters, thus favoring the use of the plants. Pre-formulation study revealed that all the evaluated parameters were found to be within acceptable limits. The weight variation of the formulated tablets was 1.43 % RSD. The disintegration time of the formulations was found to be 9.50 min. The tablets also underwent accelerated stability over the period of three months. No marked changes were observed in all the parameters evaluated during three months of accelerated stability study. Laboratory-scale preparation of polyherbal tablet can lead to new powerful and stable oral dosage formulations for diabetes mellitus and lighten the synergistic area of ​​action of herbs.
