- In order to apply the proposed method for the assay of INH in pharmaceutical preparations, six replicated determinations of 5.0 mg of INH in the presence of two fold amount of vitamin B6, three fold amount of RIF were carried out. The results of interference analysis showed that error did not exceed 1-2% and the method can be applied for the INH assay in pharmaceutical preparations.
- Since the proposed method was validated by using the analytical tests as described above, this method was successfully applied for the assay of INH in the presence of RIF also as an active ingredient in pharmaceutical preparations. Six replicate determinations were carried out on two types of tablets containing 450 mg, 600 mg of RIF respectively and 300 mg of INH. The results obtained are given in Table 3.
- Six replicate determinations were performed by the proposed method as well as the BP method on two types of tablets and two types of syrups which contained INH along with vitamin B6.
- Five standard solutions of INH of different concentrations were prepared. Sixreplicate analyses were carried out on each of these in order to assess the precision and accuracy of the proposed method. The results obtained are presented in Table 1.
- INH was treated with a known excess of copper (II) and the unreacted copper (II) was potentiometrically determined by titration against ascorbic acid making use of CBMFEas an indicator electrode.The experimental data were analyzed statistically to validate the proposed method. The lack-offit test which involves the application of analysis of variance in regression analysis was adopted for assessing the data obtained in replicate analysis of pure INH.

- A regression analysis of the amount taken for analysis Vs the amount found by six replications at each concentration level was performed for the data given in the Table 1 and a significant test namely lack-of-fit test was performed to check whether the data fit a linear model indicating the agreement between the amount taken and found in the analysis. In the test, a hypothesis stating the data to fit a linear model is considered and an F-value is calculated.
- The amount taken for analysis (µ) at each concentration level was compared with the amount found (#) by Student’s t-test.
