A Research Article on Concept of Comparative Study of Different Marketed Preparation

The purpose of this study is to use the drug assay, weight variation test, friability test, anddisintegration and dissolving test to conduct in-vitro quality control testing on Paracetamol tablets. Twobrands of Paracetamol pills, Brand A and Brand B, were utilized in the experiment. Both Brand A andBrand B of Paracetamol tablets satisfy USP criteria, per the results of quality control (QC) tests. In termsof weight variation, Brands A and B deviate from the mean weight restriction by 2.79% and 2.05%,respectively The lower mean weight limit variations are 1.21% and 1.27%, respectively. within the 10%USP standard limits. Friability tests revealed that Brands A and B were within the USP's 1% mass losslimits, with average friability of 0.062% and 0.01% mass loss, respectively. Both Brands A and B arewithin the 85%–115% USP range in terms of drug assay. Based on the disintegration test, Brands A andB had disintegration times of 6.69 and 7.02 minutes, respectively, and fall within a 15-minute time intervalsegment. The medicine dissolution percentage for Brand B of Paracetamol was 90.7% throughout thecourse of a 45-minute test.Brands A and B meet the pharmacopoeia limits set by the USP standards. Both Brands A and B's massloss, as determined by the friability test, was within the permissible limit of 1%. In comparison, the weightvariance of both brands is within the usual range of 10% above or below the mean weight. The drug assayindicated that both brands' medicine availability was within the specified 85%–115% standard range. Inless than forty-five and fifteen minutes, respectively, they finished the dissolution and disintegration tests.
