Domperidone is an antiemetic and pantoprazole is an antiulcer drug. Simple, precise, rapid and selective simultaneous equation and Q- analysis UV spectrophotometric methods have been developed for the simultaneous determination of domperidone and pantoprazole from combined tablet dosage forms. The methods involve solving of simultaneous equations and Q-value analysis based on measurement absorptivity at 216, 287 and 290 nm respectively. Linearity lies between 1-15 mcg/mL for domperidone and 0-50 mcg/mL for pantoprazole.

To develop two Chemometric-assisted analytical methods like UV spectrophotometry and RP-HPLC methods for the quantification of Atorvastatin calcium (ASC) and Aspirin (APN) in the capsule dosage form. Chemometric models used in UV spectrophotometry were Principal component regression model (PCRM) and Partial least-square regression (PLSR). Both the models were applied for the drugs in the calibration ranges of 4-20 and 30-150 μg/mL for ASC and APN respectively. Total of nineteen laboratory prepared mixtures were used for calibration and prediction set of the models. In addition, RP-HPLC method by using chemometric approach for was developed using C18 column at room temperature with a mobile phase of acetonitrile: methanol: triethylamine (53.1:11.9:35 v/v/v), pH- 3.0, with detection at 275 nm. PCRM and PLSR models were evaluated by statistical parameters and RP-HPLC method was optimized by using Response surface methodology. The developed methods like UV and RP-HPLC by using chemometrics showed almost similar results and both the methods can be used for their analysis.

Sensitive Spectrophotometric Method

A simple and sensitive spectrophotometric method for the determination of ramipril and telmisartan in pharmaceutical dosage forms has been developed. The absorption maxima were found at 220nm for ramipril and 297nm for telmisartan using 0.1N NaOH as solvent. Beer’s law was obeyed for both the drugs in the concentration range of 2-10μg/ml with correlation coefficients 0.999 for both ramipril and telmisartan. The limits of detection for ramipril and telmisartan were found to be 0.142 and 0.405μg/mL respectively and the limits of quantitation were 0.43 and 1.22μg/mL. Accuracy of the method was verified by performing recovery studies using simultaneous equation method and found to be 98.33 to 99.54%w/w for ramipril and 99.36 to 99.82 %w/w for telmisartan. %RSD of repeatability and intermediate precision studies were found to be <2 for both the drugs. Ruggedness of the method was checked by changing analyst worked and instrument used. In both the cases, the %RSD was found to be less than 2.
