Formulation, Evaluation and Comparison of the Poly Herbal Anti-Diabetic Tablet with the Commercial Tablets

Objective: To formulate a poly herbal anti-diabetic tablet and to evaluate and compare its physicochemical properties with the marketed herbal tablets. Materials and Methods: The poly herbal anti-diabetic tablet was formulated by adding the powder of extract of Enicostemma littorale in powder of roots of Aconitum heterophyllum rhizomes of Picrorhiza kurroa and fruits of Piper longum in different proportions to an aqueous 5 % Starch solution and Several tests such as visual inspection, ash values, moisture content, Water soluble extractive value and Alcohol soluble extractive value, disintegration time, Uniformity of weight of tablets, Determination of hardness of tablets, Determination of friability of tablets etc and Preliminary phytochemical screening and qualitative chemical examination were performed and compare Laboratory formulated tablets with commercial tablets. Results: The study showed that Laboratory formulated poly herbal anti-diabetic tablet has good flow property and compressibility. The moisture content of laboratory formulations was found to be 4.8%. Water extractive value was found to be 28.14% W/V result shows that laboratory formulation consisted of higher amount of water soluble substances like carbohydrates. Alcohol extractive value was found to be 20.08% W/V denotes the amount of alcohol soluble constituents present in the formulation. Disintegration of tablet was found to be 3 mins results shows laboratory formulation was within the limit as it was prepared with starch paste (5%w/v) as a binding and disintegrating agent. Disintegration of tablet is not more than 30 minutes. The laboratory formulation was found to have 3 (Kg/Cm2) hardness, 0.38 % Friability and weight variation within pharmaceutical limits. However, further research and development is required to improve its quality and safety. Conclusion: The aim of this study was to formulate a completely poly herbal antidiabetic tablet. Our Laboratory formulated tablets showed comparable good results as compare to that of marketed tablets but further research and development is required to improve its overall quality.
