This paper describes a high-performance liquid chromatographic method for simultaneous estimation of nabumetone and paracetamol in binary mixture. The method was based on RP-HPLC separation and quantitation of the two drugs on hypersil C-18 column (250 mm × 4.6 mm) using a mobile phase consisting of acetonitrile and 0.05% aqueous acetic acid (70:30v/v) at flow rate of 1 mL min-1. Quantitation was achieved with PDA detector at 238 nm based on peak area with linear calibration curves at concentration ranges 5-25 µg mL-1for both the drugs. Naproxen sodium was used as internal standard. The method has been successively applied to pharmaceutical formulation. No chromatographic interference from the tablet excipients was found. The method was validated in terms of precision, robustness, recovery and limits of detection and quantitation. The intra and inter-day precision and accuracy values were in the acceptance range as per ICH guidelines.

Abstract Simple, accurate, economical, and reproducible UV spectrophotometric and column high-performance liquid chromatographic (HPLC) methods were developed for simultaneous estimation of a 2-component drug mixture of metoprolol tartrate and hydrochlorothiazide in combined tablet dosage form. The first method used the simultaneous equation method with 7 mixed standards and the absorption maxima at 223 and 271 nm, respectively, for metoprolol tartrate and hydrochlorothiazide in methanol. Linearity was observed in the concentration ranges of 424 and 216 g/mL for metoprolol tartrate and hydrochlorothiazide, respectively. The developed HPLC method used a reversed-phase C18 column and methanolwater (95 + 5) mobile phase at an ambient temperature of 27 2C and UV detection at 225 nm; the run time was 10 min, and quantification was based on peak area. The injection repeatability and intraday and interday repeatability were calculated. Paracetamol was used as an internal standard for the HPLC method, and linearity was observed in the concentration range of 550 g/mL for metoprolol and 220 g/mL for hydrochlorothiazide. The proposed methods were successfully applied for the determination of metoprolol tartrate and hydrochlorothiazide in bulk powder and dosage form. The results obtained were analyzed statistically, and there was no significant difference between the 2 methods. The validation was performed according to International Conference on Harmonization guidelines.

A simple, accurate, precise high-performance liquid chromatographic (HPLC) method has been developed and validated for the simultaneous determination of abacavir sulphate (ABA) and lamivudine (LAM) in combined dosage form. Separation was performed on a C18 column [Agilent ODS UG 5 column, 250 mm x 4.5 mm], with methanol: water (50:50 V/V) isocratic elution using a flow rate of 1mL/min. Good sensitivity was observed with UV detection at 277 nm. After method development, the interference of other active compounds and excipients, repeatability and linearity, were investigated. Retention times of LAM and ABA were found to be 3.3 and 6.3 min, respectively. The method was validated over the range from 2.5-12.5 μg/mL for LAM and 5-25 μg/mL for ABA with correlation coefficients of 0.9997 and 0.9996, respectively. This method was shown to be accurate, robust, selective, linear, and repeatable and can be successfully employed in routine quality control for the simultaneous analysis of ABA and LAM in tablets.

Abstract This HPLC method for measuring plasma creatinine is based on cation-exchange chromatography and is particularly suitable for use with specimens from babies. A short chromatographic run is performed after simple protein precipitation with zinc sulfate and addition of an internal standard, N-methylnicotinamide. The standard curve for the method is linear up to 200 mumol/L, and analytical recovery of added creatinine is between 101% and 103%. Between-batch precision (CV) is less than 3% for mean creatinine values of 103 and 164 mumol/L. The method is free of interference from other metabolic components and drugs commonly used in neonates in routine clinical practice. Using specimens from neonates, I compared this method with a routinely used automated alkaline picrate method (from Randox Labs., performed on a Cobas MIRA analyzer). Linear-regression analysis yielded a correlation coefficient of 0.90, a slope of 1.00, and an intercept of +0.8 mumol/L. This HPLC method for creatinine should be of use in those circumstances where the alkaline picrate method is known to produce dubious results; however, the latter method is probably more suitable for routine use.
