Simultaneous Determination of Imipramine Hydrochloride and Chlordiazepoxide in Pharmaceutical Preparations by Spectrophotometric, RP-HPLC, and HPTLC Methods
A binary mixture of imipramine HCl and chlordiazepoxide was determined by three different methods. The first involved determination of imipramine HCl and chlordiazepoxide using the first derivative spectrophotometric technique at 219 and 231.5 nm over the concentration ranges of 120 and 224 g/mL with mean accuracies of 99.47 0.78 and 101.43 1.20, respectively. The second method utilized RP-HPLC with methanolacetonitrile0.065 M ammonium acetate buffer (45 + 25 + 30, v/v/v, pH adjusted to 5.6 0.02 with phosphoric acid) as the mobile phase pumped at a flow rate of 1.0 mL/min. Quantification was achieved using UV detection at 240 nm over concentration ranges of 0.254.0 and 0.11.6 g/mL, with mean accuracies of 101.17 0.56 and 100.67 0.40 for imipramine HCl and chlordiazepoxide, respectively. The third method was HPTLC with carbon tetrachlorideacetonetriethylamine (pH 8.3; 6 + 3 + 0.3, v/v/v) as the mobile phase. Quantification was achieved with UV detection at 240 nm over concentration ranges of 50600 and 20240 ng/spot with mean accuracies of 99.51 0.59 and 100.59 0.84 for imipramine HCl and chlordiazepoxide, respectively. The suggested procedures were checked using prepared mixtures, and were successfully applied for the analysis of pharmaceutical preparations. The accuracy and precision of the methods were confirmed when the standard addition technique was applied. The results obtained by applying the proposed methods were statistically analyzed.
