Fluorometholone and Sodium Cromoglycate are used in the treatment of allergic conjunctivitis. A validated HPLC method was developed for the assay of them. The method was performed on BDS HYPERSIL C18 column (250x4.6 mm, 5μ) and the mobile phase consisted of potassium dihydrogen phosphate (pH 4.5, 0.025M) - Acetonitrile (40:60, V/V) which pumped at a flow rate 1.0 ml/min at ambient temperature. 20 μl of drugs sample solutions were monitored at two fixed wavelengths (lambda = 240.0 nm for Sodium Cromoglycate and 330.0 nm for Fluorometholone). The proposed method was validated in terms of linearity, accuracy, precision and limits of detection and quantitation according to ICH
