Abstract
A simple, precise, accurate and robust RP-HPLC-PDA method was developed and validated for the determination of rilpivirine hydrochloride in tablet dosage forms. Reverse-phase chromatography was performed on a BDS hypersil (250 mm × 4.6 mm, 6 μm) column of Waters HPLC with Empower software and with a photodiode array detector. Methanol: acetonitrile: water 80:13.5:6.5 (v/v) was used as the mobile phase at a flow rate of 1 mL min-1 with PDA detection at 306 nm. Rilpivirine hydrochloride nanosuspension was prepared by using an ultrasonic homogenization method. Linearity was observed in the concentration range of 0.1–10 μg mL-1 with regression equation y = 508856X+46908 (R2 = 0.9998). The method was validated as per ICH guidelines. The RSD for intra-day (1.31- 0.67) and inter-day (1.69-1.59) precision was found to be less than 2%. The developed method is simple, precise and robust for the determination of rilpivirine hydrochloride and is successfully applied for the nanosuspension.
