A simple, rapid, accurate and economical Area under Curve method has been developed for estimation of Midodrine hydrochloride from bulk and pharmaceutical formulation. The λ max of Midodrine hydrochloride in water was found to be 289 nm. The drug follows linearity in the concentration range 12-84 μg/ml with correlation coefficient value 0.999. The proposed method was applied to pharmaceutical formulation and % amount of drug estimated 97.00% – 101.00% was found in good agreement with the label claim. The accuracy of the method was checked by recovery experiment performed at three different levels i.e., 80%, 100% and 120%. The % recovery was found to be in the range 97.00% – 101.00%. The low values of % RSD are indicative of the accuracy and reproducibility of the method. The precision of the method was studied as an intra-day, inter-day variations and repeatability. The % R.S.D. value less than 2 indicate that the method was precise. Ruggedness of the proposed method was studied with the help of two analysts. The above method was a rapid and cost-effective quality-control tool for routine analysis of Rizatriptan benzoate in bulk and in pharmaceutical dosage form.
