[A comparative study of the hemodynamic and antioxidant effects of Capoten and prazosin in patients with refractory heart failure].

Overall fifty one patients with chronic cardiac insufficiency (ChCI) were studied for changes in parameters characterizing hemodynamics and lipid peroxidation (LPO) under treatment with kapoten and prazosin. Kapoten was found to be capable of exerting an antioxidant effect and working in ways beneficial for the pulmonary circulation, while prazosin is generally indicated to patients with ChCI presenting with increased end diastolic pressure in the left ventricle. Prazosin activates LPO, for which reason its pro-oxidant action needs to be drug-corrected.
