Objective: The objective of the present work was to design a simple, accurate, economical and reproducible UV spectrophotometric method for the simultaneous estimation of a two-component drug mixture of pioglitazone and glimepiride in the combined tablet dosage form. Methodology: Simultaneous estimation method that involves maximum absorbance (λ max) of Pioglitazone and Glimepiride at 279.0 nm and 238.0 nm, respectively was developed. The proposed method was validated as per ICH guidelines for accuracy, precision, linearity, limit of quantification (LOQ) and limit of detection (LOD). The calibration curves were linear in the concentration range for pioglitazone (r value) and for glimepiride (r value) and were found to obey Beers law in the linear concentration ranges. Statistical analysis and drug recovery data showed that simultaneous estimation method was simple, rapid, economical, sensitive,precise and reproducible. Hence, the proposed method was recommended for routine analysis of pioglitazone and glimepiride in combined tablet dosage form.

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.
