Brimonidine tartrate and Timolol Maleate are used in treatment of glaucoma by decreasing intra ocular pressure. A validated HPLC method was developed for the assay of them. The method was performed on BDS HYPERSIL Cyano column (250×4.6 mm, 5 μ) and the mobile phase consisted of Ammonium acetate (pH 5.0, 0.01 M) -Methanol (40:60, V/V) which pumped at a flow rate equals to 1.5 ml/min at ambient temperature. 20 µl of drugs sample solutions were monitored at two fixed wavelengths (lambda=254.0 nm for Brimonidine Tartrate and 300.0 nm for Timolol Maleate). The proposed method was validated in terms of linearity, accuracy, precision and limits of detection and quantitation according to ICH.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
