OBJECTIVE To establish a HPLC-RID method for determination of paracetamol and amantadine hydrochloride in pediatric paracetamol and amantadine hydrochloride granules simultaneously.METHODS Waters SunFire C18 (4.6 mm×150 mm, 5μm) at 30°C was used with methanol and water (10:90, V/V) as the mobile phase, the flow rate was 1.5 mL·min-1.RID was used as the detector and the temperature of detection cell was 30°C.RESULTS The calibration curves for paracetamol and amantadine hydrochloride were linear over the range of 0.6185-4.9480 mg·mL-1 (r=0.9999), 0.2532-2.0256 mg·mL-1 (r=0.9995), resp.The average recovery rates were 99.5% (RSD=1.8%, n=9), 100.3% (RSD=1.5%, n=9), resp.CONCLUSION This method is simple, rapid, accurate and reliable, which is suitable for the quality control of pediatric paracetamol and amantadine hydrochloride granules.
