Abstract:

A new simple, precise and accurate high performance liquid chromatography (HPLC) method was developed and validated for the simultaneous determination of irinotecan (CPT-11) and two related compounds viz., 7-ethyl-10-hydroxycamptothecin (SN-38) and camptothecin (CPT) in pharmaceutical dosage. forms. Chromatography was accomplished using a reversed-phase C(18) column and ultraviolet (UV) detection and an isocratic mobile phase consisting of 3 % v/v triethylammonium acetate buffer (pH 3) and acetonitrile (70.30 v/v). The linear range of quantitation for all the compounds was 0.1-10 mu g/mL. The. limit of quantitation for all the compounds ranged between 0.01-005 mu g/mL. The method has the requisite accuracy, selectivity, sensitivity and precision to assay of CPT-11 and related compounds in pharmaceutical dosage forms and bulk API.
