An isocratic RP-HPLC method has been developed and validated for rapid simultaneous separation and determination of the mixture of omeprazole, tinidazole and doxycycline in the presence of degradation products of omeprazole and tinidazole and in their pharmaceutical dosage forms. The separation was carried out on a Hypersil® RPC18
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(More)
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(More)
Losartan potassium, Valsartan , Telmisartan and Irbesartan are angiotensin-II-receptor antagonists (ARA II) group which used in treatment of hypertension alone or in combination with other drugs mainly Hydrochlorothiazide. RP- HPLC method was developed for the assay of three angiotensin-II-receptor antagonists (ARA-IIs) in presence of Hydrochlorothiazide.(More)
