Analytical UV derivative spectrophotometric method was developed and validated to quantify Rizatriptan Benzoate in pure drug and tablet dosage form. Based on the spectrophotometric characteristics of Rizatriptan Benzoate, a signal of zero (225nm), first (216nm), second (237nm), third (233nm), fourth (231nm) order derivative spectra were found to be adequate for quantification. The methods obeyed Beer's law in the concentration range of (0.1-360µg/ml) with square correlation coefficient (r2) of 0.999. The mean percentage recovery was found to be 100.01 ± 0.075. As per ICH guidelines the results of the analysis were validated in terms of linearity, precision, accuracy, limit of detection and limit of quantification, and were found to be satisfactory.

<p><strong>Objective: </strong>The combination of thiamine hydrochloride (vitamin B1) with pyridoxine hydrochloride (vitamin B6) has been efficacious to help the metabolism of carbohydrates and amino acids. FTIR (Fourier transform infrared) is a technique widely used in compound identification and determination of functional groups but rarely used for the quantitative purposes. This study aims to obtain a analysis determination method of this vitamin combination simultaneously in tablet dosage form using FTIR.</p><p><strong>Methods: </strong>Amount of vitamin B1 and B6 standard were mixed with KBr crystal in a series of concentration (% w/w) in kalium bromide (kbr) crystal, then measured with FTIR. These spectrums yielded were transformed into an absorbance afterward changed to its derivative. The finest spectrum, which showed the best specificity and linearity, was selected and its area under the curve was calculated. The other validation parameters: accuracy, precision, detection limit, quantitation limit, and ranges, next were tested and determined. The validated method than was used to analyze the levels of vitamin B1 and B6 simultaneously in the tablets.</p><p><strong>Results: </strong>Vitamin B1 and B6 have the linear concentration range from 0.5 to 3.00% w/w. The regression equation for vitamin B1 is y = 0.0608 x-0.0176 with r = 0.9997 and Vx0 = 1.5047%, for vitamin B6: y = 0.0977 x+0.0079 r = 0.9995 and Vx0 = 1.7832%. Recovery results of vitamin B1: 98.98 to 100.93%, while B6: 99.06 to 100.43%. Intra-day and inter-day precision for vitamin B1: 1.73; 1.62; 1.48, and 0.58%, meanwhile for vitamin B6: 1.29; 1.60; 1.78, and 1.39%. The limits of detection and quantitation for vitamin B12 was 0.079 and 0.263% w/w respectively, and for vitamin B6, was: 0.093 and 0.311% w/w. The tablets from the market were tested showed the results that meet with compendia requirements.</p><p><strong>Conclusion: </strong>FTIR can be used for the determination of levels of vitamin B1 and B6 simultaneously in tablet dosage form and have met the validation requirements.</p>

Two new simple, sensitive, rapid and economical Spectrophotometric Methods (A and B) have been developed for the determination of Nelfinavir Mesylate in pharmaceutical bulk and tablet dosage form. The method A is based on the reaction of Nelfinavir with ferric chloride, potassium ferricyanide and hydrochloric acid to form a bluish green colored chromogen. The Method B is based on the formation of blood red colored chromogen with Ferric chloride and 1,10-phenanthroline. The absorbances of the chromogen were measured at their respective wavelength of maximum absorbance against the corresponding reagent blank. The proposed methods have been successfully applied to the analysis of the bulk drug and its tablet dosage form. The methods have been statistically evaluated and were found to be precise and accurate.

The Mean

Simple, fast and reliable spectrophotometric methods were developed for determination of Levocetirizine in bulk and pharmaceutical dosage forms. The solutions of standard and the sample were prepared in methanol. The quantitative determination of the drug was carried out using the zero order derivative values measured at 230 nm and the area under the curve method values measured at 227-234 nm (n=2). Calibration graphs constructed at their wavelengths of determination were linear in the concentration range of Levocetirizine using 5-25?g/ml (r=0.998 and r=0.999) for zero order and area under the curve spectrophotometric method. All the proposed methods have been extensively validated as per ICH guidelines. There was no significant difference between the performance of the proposed methods regarding the mean values and standard deviations. Developed spectrophotometric methods in this study are simple, accurate, precise and sensitive to assay of Levocetirizine in tablets.
