A stability indicating RP-HPLC method was developed and validated for the determination of Metformin HCl and Glimepiride in tablet dosage form. The method was carried out using Agilent C18 column (250 mm×4.6 mm, 5 μ) with mobile phase consisting 25 mM Hexane-1-sulphonic acid buffer adjusted to pH 2.5 with ortho-phosphoric acid and acetonitrile (45:55 v/v), at a flow rate of 1.0 mL/min and the e...
