Abstract:
An RP-HPLC method for the simultaneous determination of and Amlodipine (AL)Ramipril (RP) in tablets was developed and validated by Chinese Pharmacopoeia 2010. The linearity of the proposed method was investigated in the range of 0.01-0.25 mg/mL (r2 ? 0.9998) for RP and 0.014-0.36 mg/mL (r2 ? 0.9997) for AL. The limits of detection (LOD) were 0.06μg/mL and 0.02μg/mL for RP and AL, and the limits of quantitation (LOQ) were 0.2μg/mL and 0.07μg/mL, respectively. Some major impurities and degradation products did not disturb the detection of RP and AL and the assay can thus be considered stability-indicating.
