Abstract: The Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) of Isoniazid manufactured by different Drug Companies were determined and investigated Six INH tablets were randomly chosen from the 4 selected Drug companies and were subjected to anti-microbial effectiveness testing in vitro using Broth Dilution Method. Results were analyzed using ANOVA and their cost-effectiveness were ascertained by comparing their unit price in relation to their bacteriostatic and bactericidal activity. It was found out that there was a significant difference in the antimicrobial effectiveness of the INH tablets from the selected Drug Companies. It was apparent that INH from Drug Company A, a multi-national drug companyy, exhibited the lowest concentration to inhibit tubercle bacilli growth as well as the lowest concentration to effectiively kill the tubercle colonies in the subcultures from non-turbid tubes. These INH tablets cost much more compared to the locally produced Isoniazid. However, the fact that its anti-microbial effectiveness is superior in comparison to the other INH tablets from the other Drug Companies it can be implied that it has the greatest advantage.
