Abstract: The concept of generic prescription is prevalent in various parts of the world but it had failed to gain popularity in India due to non-availability and incredulity on product’s standard. The consumption of generic drugs compared to branded counterparts has the prospective to significantly cut-down the out-of- pocket expenditure of patients. In our study, the objective was to assess the efficacy between different branded and generic drugs against four different microorganisms. Using agar cup-plate method the antibiotic efficacy studies were observed. Dilutions of different drugs were made at concentration of 1mg/ml. After 24 hours of incubation, the zone of inhibition for each of the drug used, were measured and represented in graphical form to compare the results obtained. In the experiments were performed, four groups of drugs were taken and the zone of inhibition were measured with respect to four different organisms, that are Streptococcus sp., Pseudomonas sp., Bacillus megaterium and Salmonella abony. Itwas observed that all the four groups of drugshad shown maximum inhibition against the organism Salmonella abony whereas, minimum inhibition was showed by Streptococcus sp and Pseudomonas and Bacillus megaterium showed lowest inhibition. It was observed that difference between antibiotic efficacy of branded and generic drug was not statistically significant. Therefore, it can be said that brand names are only for mental satisfaction for consumers and doctors who prescribe, trustworthy are those generic drugs which are available at a suitable cost.

Keywords: Generic, branded, antimicrobial potential, zone of inhibition.
