摘要
A rapid and reliable micro procedure for the high pressure liquid chromatographic analysis of Cimetidine, Nʺ-cyano-Af-methyl-Nʹ-[2-[[(5-methyl-lH-imidazol-4-yl)methyl]thio]ethyl]guanidine, in serum or plasma is described. The percentage analytical recovery of Cimetidine and internal standard (β-hydroxypropyl-theophylline) was 65 and 99%, respectively. The between-day precision of the method at Cimetidine serum concentrations of 2,000, 1,000, and 500 µg/liter yielded coefficients of variation of 10.6, 11.5, and 10.6%, respectively. The method has been used in preliminary studies to determine the serum concentrations in patients receiving the drug by both the oral and intravenous route. © 1979 Raven Press, New York.
