Safaa H. Ganduh, Aseel M Aljeboree, Makarim A. Mahdi, Layth S. Jasim.


This research has been based on the development of a fast, simple, sensitive, highly selective and accurate way for spectrophotometric estimation of metoclopramide hydrochloride (MCP HCl) drug in various pharmaceutical preparations. The method spectrophotometric depends on the diazotization of the primary amino group (MCP-HCl) with hydrochloric acid and (NaNO2) solution, also by interaction with a drug considered as a coupling agent is Phenylephrine hydrochloride (PH-HCl) in an alkaline medium. After completing the reaction, the orange color is formed, evidence of forming a stable azo dye for three hours and has a wavelength of 452 nm. Beers' law was applied in the range concentration of 1-10 mg/L, Correlation coefficient (r2=0.9995). Factors affecting absorbance and color stability were studied like Effect of sodium nitrite volume, Study of kind and acid concentration, Effect of Phenylephrine hydrochloride volume reagent: the optimum temperature was 25°C, the reaction time was 5 min., and the volume of Phenylephrine hydrochloride (PH-HCl) reagent was 1ml. The limit of detection (LOD) 1.21 x 10-2, the limit of quantification (LOQ) 4.063x10-2. Recoveries range 96.1%-104.1%. The way has been successfully useful to analyze the compound (MCP-HCl) in its pharmaceutical preparations (tablets, syrup).

Key words: Colorimetric, Spectrophotometric, Determination, Phenylephrine hydrochloride Metoclopramide- HCl.
