Abstract
A micellar liquid chromatographic method was developed for determination of tinidazole in bulk, dosage forms and human plasma using intersil cyano column and a mobile phase of 0.1 M sodium dodecyl sulphate, 20% 1-propanol, 0.3% triethylamine in 0.02 M orthophosphoric acid:water (60:40, v:v) (pH = 4). The U.V. detection was achieved at 311 nm. Various chromatographic parameters were investigated to select the optimum conditions for the separation, e.g. types of columns, pH of mobile phase, concentration of sodium dodecyl sulphate, 1-propanol, triethylamine, etc. The method was linear over the concentration range 40-200 µg/mL with regression coefficient 0.999. The result obtained by the proposed method was compared with that obtained by the reference HPLC technique. Furthermore, the proposed method was successfully applied as stability-indicating method for determination of tinidazole under different stressed conditions. The method showed good selectivity, repeatability, linearity and sensitivity according to the evaluation of the validation parameters.
