Dopexamine is a chemical compound from the group of catecholamines , which is used in medicine as a medicinal substance in the treatment of heart failure . The substance acts as a beta-1 and beta-2 sympathomimetic .
Clinical information
It is used in acute therapy for severe heart failure at a dose of 1–4 µg / kg / min. The administration is contraindicated in the presence of angina pectoris and pulmonary embolism .
Pharmacological properties
Dopexamine has a strong adrenergic β and DA 1 receptor effect and thus leads to vasodilation and a reduction in afterload, which leads to an increase in the oxygen supply and the cardiac output . It also inhibits the reuptake of norepinephrine at neural nerve endings. This inhibition is about ten times stronger with dopexamine than with the pharmacological analogue dopamine . It does not have a vasoconstrictive effect. Dopexamine has been thought to have a positive effect on splanchnic perfusion, but the data on this are contradicting. Dopexamine has a slightly positive inotropic effect .
