title: Analytical problems encountered during high-performance liquid chromatographic separation and coulometric detection of bopindolol metabolites in human plasma.
abstract: Good clinical control of hypertension is achieved with low doses of the potent beta-blocker bopindolol. Pharmacokinetic evaluations therefore require an analytical technique of high sensitivity. Analysis of plasma by high-performance liquid chromatography (HPLC) using electrochemical detection provides this sensitivity. This article describes the development of an analytical procedure and presents a reversed-phase HPLC method with coulometric detection suitable for plasma analyses during pharmacokinetic investigations of bopindolol therapy.
