Abstract

A rapid and simplified high-performance liquid chromatographic (HPLC) method is presented for the determination of theophylline in sustained release tablets (Controfilina-200). The mobile phase consists of acetonitrile-distilled water pH 4 in the 9 : 91 (v/v) ratio. This paper presents specificity, linearity, accuracy, precision, sample stability and ruggedness data. The calibration curve showed excellent linearity over the range of concentration examined (50-120 %). Correlation coefficient (r) of calibration curve was calculated 0.999. The method was precise because it found coefficients of variation less than 1 %. The assay recovery was more than 90 %. The stability of the sample during 24 h was good. The method is specific for theophylline.
