Development and Validation of RP-HPLC Method for Determation of Acyclovir in Ointment

Abstract

The analytical method was developed and validated for determination of acyclovir in ointment by High performance liquid chromatography. The separation was carried out on Luna C18 column (250 × 4.6mm × 5µ). The mobile phase consists of water: acetonitrile in the ratio 88:12 at flow rate 0.8ml/min with diode array detector wavelength at 254nm.The column temperature was adjusted at 30ºC±40ºC with injection volume 20µl.The retention time of acyclovir was 4.747min. The linearity of the calibration curve was linear over the concentration range 80-120µg/ml (r2=0.9996). The validation was carried out as per ICH guidelines. The development method was easy, rapid, linear, precise, accurate and consistent.
