Quantitative analysis of Codelac Broncho tablets and syrup by high-pressure liquid chromatography


A procedure was proposed for quantitative analysis of Codelac Broncho tablets and syrup, a new original drug, by high-pressure liquid chromatography. The active principles of the tablets were separated in 6 min with an efficient resolution of all component peaks. Preproduction tablet samples were analyzed. The results of the analysis meet the requirements of normative technical documentation and technologic loads. The adequacy of the results was validated by the analysis of model solutions that contained all active principles and adjuvants. For the syrup, two versions of analysis were proposed, in isocratic and gradient elution modes. These versions are virtually equivalent with respect to the analysis time and precision. The isocratic elution version is, however, easier to implement and is proposed for inclusion into the draft pharmacopoeic standards for commercial production.
