Determination of fenoverine in tissue samples by high-performance liquid chromatography.
Fenoverine is a spasmolytic, non-anticholinergic phenothiazine derivative that inhibits calcium channel currents. We describe a high-performance liquid chromatographic method for the determination of fenoverine in striated muscle, smooth muscle, myocardium, and liver tissue. Reversed-phase liquid chromatography was performed on a 5 microns Nucleosil C18 column with acetonitrile-0.015 M phosphate buffer (28:72, v/v) as a mobile phase and detection with ultraviolet at 214 nm. The limit of quantitation of fenoverine in tissue samples was 25 ng injected. This method is well suited for the determination of fenoverine in various organs in animal experiments.
