This work deals with the simultaneous estimation of famotidine and diclofenac potassium in a tablet dosage form. The method employed is simultaneous equation. The absorption maxima at 266 nm and 286 nm were used for the estimation of famotidine and diclofenac, respectively. Both the drugs and their mixture obey Beer-Lamberts law at selected wavelength in given concentration range. The result of analysis has been validated statistically and recovery studies confirmed the accuracy of the proposed method. The proposed method is simple, rapid, precise and accurate. It is used for the routine analysis of both drugs.

Developing a single analytical method for estimation of individual drug from a multidrug composition is a very challenging task. A complexation, derivatization, extraction, evaporation, and sensitive-free direct UV spectrophotometric method is developed and validated for the simultaneous estimation of some antiviral drugs such as emtricitabine (EMT), tenofovir disoproxil fumarate (TDF), and rilpivirine HCl (RPV) in tablet dosage form by Vierordt’s method. The solutions of standard and sample were prepared in methanol. The λmax⁡ for emtricitabine, tenofovir disoproxil fumarate, and rilpivirine hydrochloride were 240.8 nm, 257.6 nm, and 305.6 nm, respectively. Calibration curves are linear in the concentration ranges 4–12 μg/ml for EMT, 6–18 μg/ml for TDF, and 0.5–1.5 μg/ml for RPV, respectively. Results of analysis of simultaneous equation method were analyzed and validated for various parameters according to ICH guidelines.

Simple, accurate, precise, reproducible, requiring no prior separation, and economical procedures for simultaneous estimation of benazepril hydrochloride (BEN) and Hydrochlorothiazide (HCT) in tablet dosage form have been developed. Simultaneous equation method employs for estimation of both drugs in methanol at 240 nm and 270 nm as two analytical wavelengths. BEN and HCT at their respective λmax (240 nm and 270 nm) show linearity in a concentration range of 2–12 μg/mL and 4–14 μg/mL. Recovery studies for BEN are 100.0–100.6% and 99.8–100.0% for HCT in the case of simultaneous equation method confirming the accuracy of the proposed method. The proposed method is recommended for routine analysis since it is rapid, simple, accurate and also sensitive and specific.

A simple, rapid, sensitive and economical UV spectrophotometric method was developed and validated for the simultaneous estimation of aspirin, caffeine, and orphenadrine citrate by Vierodt’s method in combined tablet dosage form and using mixture of 0.1 N HCl: ethanol (1:1) as solvent. The method employs designing and solving of simultaneous equations using 3 wavelengths, namely 226 nm, 272 nm, and 210 nm. Beer’s law was obeyed in the concentration range of 3-18 μg/mL for aspirin and 0.5-12 μg/mL for both caffeine and orphenadrine citrate with r2 value of 0.993, 0.991, and 0.991 respectively. Accuracy was determined by recovery studies and showed percent recovery ranging from 99.78-100% for aspirin, 96.10-100.92% for caffeine and 100.53-102.5% for orphenadrine citrate. The developed method can be used in QC laboratory for routine analysis to ensure the identity, purity, and performance of the drug product.

Ambroxol Hydrochloride and Cetirizine Hydrochloride are used for the treatment of bronchitis, cough, and allergy. A simple, economical, accurate, and precise method for simultaneous estimation of Ambroxol Hydrochloride and Cetirizine Hydrochloride in tablet dosage form has been developed. Simultaneous equation method based on measurement of absorbance at two wavelengths, that is, 244 nm and 230 nm, λmax of Ambroxol Hydrochloride and Cetirizine Hydrochloride in pH 6.8 phosphate buffer. Both of these drugs obeyed Beer-Lambert’s law in the concentration range of 2–18 µg/mL for Ambroxol Hydrochloride and 2–20 µg/mL for Cetirizine Hydrochloride. The high values of correlation coefficient (R) indicated good linearity of calibration curve for both the drugs. The accuracy and precision of method were determined and the method was validated statistically. Result of percentage recovery study confirms the accuracy of proposed method. As per the ICH guidelines, the method validation parameters checked were linearity, accuracy, precision, and assay of drug formulation. Based on the results obtained, it can be concluded that the proposed simultaneous equation spectrophotometric method for simultaneous estimation of Ambroxol Hydrochloride and Cetirizine Hydrochloride is rapid, economical, accurate, precise, and reproducible. Hence, the proposed method can be employed for quantitative estimation of Ambroxol Hydrochloride and Cetirizine Hydrochloride from their tablet 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.
