| pubmed-article:730797 | pubmed:abstractText | A gas-liquid chromatographic method for the evaluation of the new anti-hypertensive drug propildazine (ISF 2123) in rat plasma is described. The procedure involves separation of the drug from plasma by cation-exchange chromatography, subsequent acylation of the dried eluate with heptafluorobutyric anhydride and quantitation with electron-capture detection. Propildazine can be determined in concentrations down to ca. 0.4 microgram/ml. | lld:pubmed |
