Abstract

Aim: The aim of the present investigation is to design of sustained release dosage form of different extracts that will help in releasing only small quantities of drug over a prolonged period of time. Material and Methods: The different ingredients for formulations are given as in Table 1 below. The measured quantities of drug, HPMC, MCC and NaHCO3 were mixed thoroughly using a mortar and pistil. The granules were punched into tablets using direct compression technique. The blank formulation (or) placebo (HPMC+ MCC+NaHCO3) and polyherbal formulation were also tested using FTIR Spectrometer. The release rate kinetics of the formulations was analyzed and the data obtained were fitted into Zero order, First order, Higuchi model and Kozmeyer Peppas model. Results: The pre-formulation study results obtained on various parameters on granules were found satisfactory. The granules obtained for the batches (F1-F12) were satisfactory. No rat holing, capping or sticking was observed during the flow of granules from the hopper. The maximum weight variation of the tablets was±1.8%, which falls within the acceptable range of±5%, hence the tablets passed the weight variation test. Hardness for tablets of all batches was in the range of 4.92 to 5.35 kg/cm², which falls above the limit of not less than 3.0 kg/cm². The floating lag time ranged from 35 s to 50 s. From the Table 5, it was found that the formulation F11 has the minimum floating lag time of 35 s and maximum total floating time of 15 h with 100.12% drug content. Conclusion: The effect of ingredients in the polyherbal tablet was analyzed, where HPMC contributed as the floating matrix, MCC to increase the bulk density of the tablet and sodium bicarbonate to initiate the dissolution process.
