Sensitive Spectrophotometric Method

A simple, rapid, accurate, precise and reproducible UV spectroscopic method has been developed for the simultaneous estimation of pitavastatin calcium and fenofibrate in bulk and pharmaceutical dosage form. The method is based on simultaneous equation method. Pitavastatin calcium and fenofibrate have absorption maxima (λmax) at 245 nm and 286 nm respectively. Beer’s law was obeyed in the concentration range of 2-12 μg/mL and 32-192 μg/mL for pitavastatin calcium and fenofibrate, respectively. The recovery studies are indicative of accuracy of method and are found in between 97.66-107.22% and 103.33-110.55% for pitavastatin calcium and fenofibrate, respectively, at three different levels of standard additions. Precision studies showed satisfactory results.

Objective: A new, simple, precise, accurate, and reproducible method or simultaneous equation method was developed and validated for the simultaneous estimation of terbinafine hydrochloride (TH) and fluconazole (FLZ) in pure form. Methods: Simultaneous estimation of terbinafine hydrochloride and fluconazole was estimated by the ultraviolet (UV) spectrophotometry method. The method was based on the measurement of absorbance at two wavelengths 222 nm and 239 nm, of terbinafine hydrochloride and fluconazole in 0.1N HCl respectively. Results: Calibration curves terbinafine hydrochloride and fluconazole were found to be linear in the concentration ranges of 0.5-3.0 μg/ml and 80-400 μg/ml, respectively, with their correlation coefficient values (R2) 0.999 and 0.998. LOD and LOQ of TH were found to be 0.067, 0.203 at 222 nm and 0.175, 0.531 at 239 nm, similarly for FLZ; 31.089, 94.210 at 222 nm and 94.380, 286.00 at 239 nm respectively. In the precision study, the % RSD value was found within limits (%). The percentage recovery at various concentration levels varied from 98.50 % to 103.96 % for TH and 97.27 % to 103.83 % for FLZ confirming that the expected method is accurate. Conclusion: It could be concluded from the results obtained in the present study that this method for simultaneous estimation of TH and FLZ in pure is simple, precise, and economical. The proposed method can be applied successfully for the simultaneous estimation of TH and FLZ in the pure and pharmaceutical dosage form.

A new, rapid, precise, selective and sensitive Vierodt���s/simultaneous equation method is developed for the simultaneous estimation of pantoprazole (PNT) and cinitapride (CNT) in combined dosage form. In the developed method, absorbance was measured at 289 nm (�� max of Pantoprazole) and 267.2 nm (�� max of Cinitapride). The drugs obeyed the Beer���s law in the concentration range of 13-65��g/ml and 1-5 ��g/ml respectively for pantoprazole and cinitapride. Accuracy of the method was determined by recovery studies and was found to be 101.32 % and 98.9 % for Pantoprazole and Cinitapride respectively. The developed method is simple, precise, rapid and selective. It can be used for routine analysis of both drugs in bulk as well as in pharmaceutical formulations.

Tablet Dosage

Two UV-spectrophotometric methods have been developed and validated for simultaneous estimation of valsartan and hydrochlorothiazide in a tablet dosage form. The first method employed solving of simultaneous equations based on the measurement of absorbance at two wavelengths, 249.4 nm and 272.6 nm, λmax for valsartan and hydrochlorothiazide, respectively. The second method was absorbance ratio method, which involves formation of Q-absorbance equation at 258.4 nm (isoabsorptive point) and also at 272.6 nm (λmax of hydrochlorothiazide). The methods were found to be linear between the range of 5–30 µg/mL for valsartan and 4–24 μg/mL for hydrochlorothiazide using 0.1 N NaOH as solvent. The mean percentage recovery was found to be 100.20% and 100.19% for the simultaneous equation method and 98.56% and 97.96% for the absorbance ratio method, for valsartan and hydrochlorothiazide, respectively, at three different levels of standard additions. The precision (intraday, interday) of methods was found within limits (RSD<2%). It could be concluded from the results obtained in the present investigation that the two methods for simultaneous estimation of valsartan and hydrochlorothiazide in tablet dosage form are simple, rapid, accurate, precise and economical and can be used, successfully, in the quality control of pharmaceutical formulations and other routine laboratory analysis.

A simple, rapid and precise method was developed for the quantitative simultaneous determination of Omeprazole and Domperidone in combined pharmaceutical-dosage forms. The method was based on UV-Spectrophotometric determination of two drugs, using simultaneous equation method. It involves absorbance measurement at 291 nm (λmax of Omeprazole) and 289 nm (λmax of Domperidone) in Methanol: Acetonitrile (30:70 v/v). For UV Spectrophotometric method, linearity was obtained in concentration range of 1-15 µg/ml for Domperidone and 1-50 µg/ml for Omeprazole respectively, with regression 0.999 and 0.999 for Domperidone and Omeprazole respectively. Recovery was in the range of 99 -103%; the value of standard deviation and %R.S.D were found to be < 2 %; shows the high precision of the method., in accordance with ICH guidelines. The method has been successively applied to pharmaceutical formulation and was validated according to ICH guidelines.
