  Two simple, rapid and sensitive spectrophotometric methods have been proposed for the determination of milrinone in pharmaceutical formulations. The first method is based on the charge transfer complexation reaction of milrinone with 2, 3-Dichloro-5, 6-Dicyanobenzoquinone, DDQ while the second method is based on charge transfer reaction of milrinone with p-Chloranilic Acid (pCA). Under the optimized experimental conditions Beer's law is obeyed in the concentration range of 2-40 μg mL-1 for method A and 5-100, 2-40 μg mL-1 for method B. The recovery ranged from 100.06 -100.11 for method A and from 99.34 -99.97 for method B. The coefficient of correlation was found to be 0.9998 for A and 0.9999 for B and the detection limit for method A and method B was found to be 0.765 and 3.35, respectively. Both the methods have been applied to determination of milrinone in the pharmaceutical formulation. Results of the analysis are validated statistically.

  A simple and sensitive assay method was developed for simultaneous determination of cefepime and sulbactam sodium in Supime (a fixed dose combined formulation of cefepime and sulbactam manufactured by Venus Remedies limited, India) with UV detection at 230 nm. Chromatographic separation of two drugs was achieved on a Hypersil ODS C-18 column using a binary mixture of acetonitrile and tetrabutyl ammonium hydroxide as a mobile phase adjusted to pH 5.0 with orthophosphoric acid in ratio 20:80 v/v ratio. The developed liquid chromatographic method offers good linearity, accuracy and precision over the concentration range of 125-750 ppm for cefepime and 62.5-375 ppm for sulbactam sodium. This method was successfully applied for the quality control of formulated products and plasma samples containing Cefepime and sulbactam. Since, Supime, a fixed dose combination of cefepime and sulbactam is a research product of Venus Remedies limited the literature lacks any method of analysis for such combination, the main motive behind this experiment was to develop and validate a method which could be used for the quality control of cefepime and sulbactam in combined dosage form.
