A simple, rapid and sensitive high-performance liquid chromatographic (HPLC) method for the determination of risperidone in human plasma was developed. An HPLC system based on a Nucleosil C8 column (150?4 mm) and a UV detector (?= 280 nm) were used. A mixture of sodium dihydrogen phosphate buffer-acetonitrile (55:45, v/v) adjusted to pH 6.0 at a flow rate of 1.5 ml min-1 was used as mobile phas...
