Abstract:
:An isocratic high-performance liquid chromatography method with amperometric detection for the assay of plasma salbutamol is described. The plasma extract is injected into the chromatographic system via a loop column. This insures the purification of the injected extracts and allows a simple and rapid liquid-solid extraction procedure. The good reliability, as shown by the low limit of detection (0.5 ng/ml) and a precision ranging between 5 and 10%, has permitted the investigation of a new mode of administration of salbutamol using a portable subcutaneous infusion pump. Our results show that subcutaneous administration yields plasma levels comparable with those obtained after usual intravenous doses.
