Capecitabine is a 'pro-drug' to the cytotoxic agent 5-fluorouracil (5-FU) intended to administered orally. Capecitabine is generally used as first line monotherapy for advanced colon cancer. Simple, rapid, accurate UV spectrophotometric methods were developed in the present study and validated for the estimation of Capecitabine in bulk and its formulations as per ICH guidelines. Three solvent systems viz., 0.1N NaOH, 0.1N HCl and Methanol: Water (1:3) was tried. The results suggest that the developed method shows linearity over the range of concentration 2-24μg/ml and a correlation coefficient of 0.9999. Accuracy, precision, linearity, robustness, and ruggedness were statistically validated as per ICH guidelines for all the developed methods. The % RSD values for validated methods were found to be less than 1.5 and methods will find application in routine analysis of drug formulations containing Capecitabine.

The article highlights the use of a highly sensitive method based on immunomicrochip technology in the current practice of veterinary and sanitary expertise of aquaculture (fish and fish products) for the presence of residual amounts of antibiotics. To do this, we used a test of Antimicrobial Array I Ultra and Antimicrobial Array II Plus from Randox (UK) in accordance with the instructions. Duration of analysis 2 ... 3 hours. Based on our studies, the optimal parameters for detecting residual quantities of various groups of antibiotics in fish using the immunomicrochip method were determined, and the sensitivity and specificity of these test systems were established. Using the Antimicrobial Array I Ultra panel, the residual amounts of 20 antibiotic drugs and sulfonamides simultaneously were determined in one sample. The detection limit in this fish panel is 1.6 to 6.5 μg / l. With the help of the Antimicrobial Array II Plus panel, the residual amounts of 35 antibacterial drugs were simultaneously determined, including 10 types of tetracycline and 17 quinolone compounds. The detection limit in fish is from 0.9 to 14.0 μg / l. In this case, the results are obtained in a quantitative equivalent, and not as a "yes-no" answer.
