Abstract
Desoximetasone chemically is 9-fluoro-IIβ21-dihydroxy-I6a-methylpregna-I.4-diene-3.The precise mechanism of the anti-inflammatory activity of topical steroids in the treatment of steroid-responsive dermatoses, in general, is uncertain. So, in present investigation chromatographic methods were developing use RP-HPLC for estimation of Desoximetasone in bulk and in cream formulation and method validation according to ICH guidelines. The main objective of this study was to develop a simple and reproducible method for desoximetasone by Reverse Phase High Performance Liquid Chromatography (RP-HPLC). In this work the desoximetasone separation was carried out by using C18 cosmosile column (250mmx4.6mm particle size 5µm). By using 0.1% orthrophosphoric acid pH adjusted up to 3 at uv detection of 240nm.The mobile phase was used at various ratio for gradient elution the ratio of mobile phase was 20:80 v/v. Methanol and water used for mobile phase and flow rate was being set at 1mL/min. The linearity of proposed method was found in range of r =0.9989. Statistically validation parameters such as linearity, accuracy, precision, LOD and LOQ were checked.
 Keywords: Desoximetasone, RP-HPLC, Method validation.
