Simple, accurate, and reproducible two UV-spectrophotometric methods have been developed for simultaneous estimation of Olmesartan Medoxomil (OLME) and Metoprolol Succinate (METO) in tablet dosage form. The first UV- Spectrophotometric method was a determination using the Area Under Curve method and the second UV method was a determination using the Multi-Component mode method at 256.5 nm and 222.0 nm over the concentration range 5-30 μg/mL and 5-30 μg/mL for OLME and METO respectively. Both UV-spectrophotometric methods were statistically validated and can be used for analysis of combined dose tablet formulation containing OLME and METO.
