Itopride Hydrochloride

Three simple, precise and economical UV methods have been developed for the estimation of itopride hydrochloride in pharmaceutical formulations. Itopride hydrochloride in distilled water shows the maximum absorbance at 258.0 nm (Method A) and in first order derivative spectra of the same shows sharp peak at 247.0 nm, when n = 1 (Method B). Method C utilises area under curve (AUC) in the wavelength range from 262.0-254.0 nm for analysis of itopride hydrochloride. The drug was found to obey Beer-Lambert’s law in the concentration range of 5-50 μg/mL for all three proposed methods. Results of the analysis were validated statistically and recovery studies were found to be satisfactory.

Four simple, rapid, accurate, precise, reliable, and economical UV-spectrophotometric methods have been proposed for the determination of tadalafil in bulk and in pharmaceutical formulation. “Method A” is first order derivative UV spectrophotometry using amplitude, “method B” is first order derivative UV spectrophotometry using area under curve technique, “method C” is second order derivative UV spectrophotometry using amplitude, and “method D” is second order derivative UV spectrophotometry using area under curve technique. The developed methods have shown best results in terms of linearity, accuracy, precision, and LOD and LOQ for bulk drug and marketed formulation as well. In N,N-dimethylformamide, tadalafil showed maximum absorbance at 284 nm. For “method A” amplitude was recorded at 297 nm while for “method B” area under curve was integrated in the wavelength range of 290.60–304.40 nm. For “method C” amplitude was measured at 284 nm while for “method D” area under curve was selected in the wavelength range of 280.80–286.20 nm. For methods A and B, tadalafil obeyed Lambert-Beer’s law in the range of 05–50 μg/mL while for “methods C and D”, tadalafil obeyed Lambert-Beer’s law in the range of 20–70 μg/mL, and-for “methods A, B, C, and D” the correlation coefficients were found to be > than 0.999.

Raloxifene Hydrochloride

Raloxifene hydrochloride (RLF) is a non-steroidal, selective estrogen receptor modulator used in the treatment and prevention of osteoporosis in postmenopausal women. Two simple, rapid and economical 'zero order UV-spectrophotometric (method I)' and first order derivative spectrophotometric (method II) using area under curve (AUC) technique have been developed for estimation of RLF in bulk and tablets. In 0.1N NaOH, RLF showed maximum absorbance at 303.5 nm. In method I, AUC between two wavelengths 275.0 nm & 350.0 nm were selected. In method II, UV-spectrum of RLF was derivatized into first order and two wavelengths 303.0 nm and 385.0 nm were selected for determination of AUC. In both these methods, RLF obeyed linearity in the concentration range of 2-10 mcg/mL (r2>0.99). Proposed methods were applied for tablet formulations and amounts of RLF estimated by method I and method II were found to be 100.08±0.68 and 99.78±0.94, respectively. Both these methods were validated statistically and by recovery experiments.

First method includes determination of nabumetone at absorption maxima 330 nm, second method applied was area under curve for analysis of nabumetone in the wavelength range of 326-334 nm and third method was First order derivative spectra with scaling factor 4. Beer law obeyed in the concentration range of 10-30 μg/mL for all three methods. The correlation coefficients were found to be 0.9997, 0.9998 and 0.9998 by absorption maxima, area under curve and first order derivative spectra. Results of analysis were validated statistically and by performing recovery studies. The mean percent recoveries were found satisfactory for all three methods. The developed methods were also compared statistically using one way ANOVA. The proposed methods have been successfully applied for the estimation of nabumetone in bulk and pharmaceutical tablet dosage form.

Abstract: A simple, precise and economical UV-spectrophotometric method has been developed for the estimation of Olmutinib from bulk. Two methods were developed First method (A) applied was area under curve (AUC) in which the area was integrated in wavelength from 262-272nm. Second method (B) was first order derivative spectrometric method. In this method absorbance at λmin=256.57nm, λmax=282.83nm and zero cross=267.68nm was measured. Calibration curves were plotted for the method by using instrumental response at selected wavelength and concentration of analyte in the solution. In both the methods, linearity was observed in the concentration range of 2-12µg/ml at the λmax=267.68nm. Accuracy and precision studies were carried out and results were satisfactorily obtained. The drug at each of the 80 %, 100 % and 120 % levels showed good recoveries that is in the range of 98.00 to 99.00% for both methods, hence it could be said that the method was accurate. Limit of detection (LOD) and limit of quantitation (LOQ) were determined for the method. The method was validated as per International Conference on Harmonization. All validation parameters were within the acceptable limit. The developed method was successfully applied to estimate the amount of Olmutinib in pharmaceutical formulation.
