A new analytical method development and validation for the estimation of Midodrine HCl by UV and HPLC

http://dx.doi.org/10.21276/IJRDPL.22780238.2018.7(4).3060-3070 ABSTRACT:Two simple, accurate, sensitive and precise reverse phase-high performance liquid chromatographic and U.V. assay method for estimation of Midodrine hydrochloride (MD) was developed in tablet formulation. The chromatographic separation was performed on Thermo C18, (250 mm X 4.6 mm, 5 μm) column. The mobile phase consists of water: acetonitrile (30:70 v/v) pH adjust 3.5 with TEA was delivered at a flow rate of 1.0 ml/min and UV detection at 272 nm. The retention time of the drug was found to be 3.89 min. The developed method was found to be linear in a concentration range of 5-25μg/ml of the drug (r2= 0.999). The low value of % RSD indicates reproducibility of the methods. The low value of LOD and LOQ suggests the sensitivity of the method. Thus, this method can be used for routine analysis of Midodrine hydrochloride formulation and to check the stability of bulk samples.
