Abstract

In the present study, spectrophotometric method was developed and validated using multicomponent mode for simultaneous estimation of Salbutamol Sulphate and Theophylline in combined tablet dosage form. Distilled water was used as a solvent. Considering the absorption of both the analytes in the range of 200 nm - 320 nm, four wavelength of equal interval of 40 nm were selected such as 320 nm, 280 nm, 240 nm and 200 nm for analysis of these drugs. The mean percentage assay was found as 100.50% and 100.79% for Salbutamol Sulphate and Theophylline respectively. Results of analysis were validated statistically in accordance with ICH guidelines for accuracy and precision of the method. The results of recovery study were observed in the range of 93.26-99.24%. for Salbutamol Sulphate and 97.39-103.615% for Theophylline, While, the % RSD for precision study was observed less than 1 %. So, it can be concluded that, the developed method is simple, accurate, economical and easy to apply, making it suitable for routine analysis of Salbutamol Sulphate and Theophylline in tablet dosage form.

Abstract

A specific, accurate, precise and sensitive validated reverse phase liquid chromatographic (RP-HPLC) method has been developed for the simultaneous estimation of Ofloxacin, Ornidazole and its isomer in bulk drug as well as tablet dosage form. Drugs were analysed on C18 column using mobile phase acetonitrile: methanol:0.025 M phosphate buffer (pH 3.0) (30:10:60 v/v/v). A flow rate was maintained at 1.0 ml/min and detection was made at 318 nm. The retention time for Ofloxacin, Ornidazole and its isomer was found to be 4.04, 5.82 and 6.77 min respectively. Proposed method was validated for accuracy, precision, linearity and range, ruggedness. Linearity of Ofloxacin and Ornidazole was in the range of 2-40 μg/ml and 5-100 μg/ml respectively. Average percentage recoveries obtained for Ofloxacin and Ornidazole were 100.20% and 100.9%.
