New first derivative ratio spectrophotometric method was developed for simultaneous estimation of telmisartan hydrochloride (TELM) and hydrochlorothiazide (HCTZ) in combined tablet dosage form without prior separation. The amplitude in the first derivative of the corresponding ratio spectra at 263.2 nm and 278.4 nm of TELM and for HCTZ at 287.2 nm and 304.8 nm were selected for the determination. The calibration graphs were established in the range of 1-10μg/mL and 2-15 μg/mL of TELM and HCTZ, respectively. The percentage recoveries of binary mixture of TELM were found to be 97.81±1.05 (263.2nm) and 96.60±1.91 (278.4nm) and for HCTZ were found to be 97.47±1.41 (287.2), 98.16± 1.45 (304.8nm) by proposed method. This method was successfully applied for the analysis of commercial tablet formulation, with no interference from excipients as indicated by the recovery study results. The proposed method was validated, statistically analyzed, compared with reported HPLC method and can be successfully applied for the routine analysis.

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.

A simple, accurate, precise, rapid, economical UV spectrophotometry method, dual wavelength spectrophotometry, has been developed and validated for estimation of Indapamide (IND) and Amlodipine besylate (AML) in combined tablet dosage form and can be used in routine analysis. In this method, the absorbance at 360 nm and 256 nm of AML were same and no interference of IND at 360 nm. was observed. So, absorbance difference at 256-360 is used for estimation of IND and absorbance at 360 nm used for AML. The method was found to be linear in the concentration range of 3-18 μg/mL for IND (r2>0.99962) and 10-60 μg/mL for AML (r2>0.99969). Mean assay was found to be 99.32% and 101.34% for IND and AML respectively. In first order derivative spectrophotometry, the absorbance at 237.4 nm (ZCP of AML) and 241 nm (ZCP of IND) were used for estimation of IND and AML respectively. The method was found to be linear in the concentration range of 1.5-9 μg/mL for IND(r2=0.99983) and 5-30 μg/mL for AML(r2=0.99966). Mean assay was found to be 99.72% and 100.28% for IND and AML respectively.

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 simple high performance thin layer chromatographic method for simultaneous determination of rupatidine fumarate and montelukast sodium in bulk and tablet dosage form was investigated. Chromatographic separation of the drugs was performed on aluminum plates precoated with silica gel 60 F254 as the stationary phase and the solvent system consisted of acetone:methanol:toluene (2:3:5, V/V/V). Densitometric evaluation of the separated zones was performed at 286 nm and the method was validated. The Rf values and drug content of rupatidine fumarate and montelukast sodium were 0.57±0.02, 0.68±0.02 and 98.3%, 97.67% respectively. The calibration curves of peak area versus concentration, were linear from 50-300 ng per band for both rupatidine fumarate and montelukast sodium and the regression coefficient (r2 ) was greater than 0.99. The method was validated for linearity, accuracy, robustness and application for assay as per ICH guidelines. The study showed that the developed method was simple and accurate and would be suitable for the simultaneous determination of rupatidine fumarate and montelukast sodium in bulk and pharmaceutical formulations.

A simple, rapid, precise and highly selective spectrophotometric method was developed for simultaneous estimation of Hesperidin and Diosmin in tablet dosage form. This method, involves the measurement of absorbances of Hesperidin and Diosmin at the wavelengths of 285 nm (λmax of Hesperidin) and 268 nm (λmax, of Diosmin). The UV spectra’s of Hesperidin and Diosmin prepared in different solvents water, methanol, and acetonitrile and 0.2 N sodium hydroxide were recorded. These two drugs showed good absorbances when dissolved in 0.2 N NaOH. Hence 0.2 N NaOH was selected as the solvent for the method. Two wavelengths 285 and 268 nm were selected which are λmax of two drugs Hesperidin and Diosmin, respectively. Different concentrations of Hesperidin (5–50 μg/mL) and Diosmin (2–24 μg/mL) and a mixture of Hesperidin and Diosmin were prepared, scanned and absorbances were noted at the two wavelengths were fixed for the study. The method showed good reproducibility and recovery with % RSD less than 2. The LOD of Hesperidin and Diosmin was found to be 0.139 μg/mL and 0.048 μg/ml and LOQ of Hesperidin and Diosmin was found to be 0.42 μg/mL and 0.147 μg/mL, respectively. Thus the proposed method was found to be rapid, specific, precise, accurate and cost effective quality control tool for the routine analysis of Hesperidin and Diosmin in bulk and combined dosage form.

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.
