ABSTRACT

Tablet is a pharmaceutical unit dosage form. Various brands of same dosage forms are available in the market with the common claim that they are all complies the standard pharmacopoeia. Total five different brands of Metformin tablets from different manufacturers were selected in the study. Dissolution testing was conducted according to USP from each brand for 25 minutes by using dissolution testing apparatus USP type-I (Basket). The tablets were subjected to various post-production tests such as hardness, physical parameters like weight variation, chemical parameters like assay, disintegration also considered for this study. Assay and Dissolution was checked by using a UV Spectrophotometer where Phosphate Buffer was used as dissolution medium. From the analysis of the results, it was observed that there was a considerable variation in the dissolution rates and also in the pattern of hardness, assay, friability, disintegration and weight of tablets. The disintegration, hardness and weight variation test of Tablets were performed as mentioned in BP or USP in world class equipment. All the results of these tests were matched USP standards. If the disintegration time, hardness, weight variation of Tablets varies a lot from the standard time, the tablets will not be able to show the desired therapeutic effect on time in the patients, which in result will increase the risk of patients. From the analysis of the results, this was observed that there was a considerable variation in the dissolution rates and also in the pattern of hardness, assay, friability, disintegration and weight of tablets.
