Background:
Etamicastat (BIA 5-453) is a potent and reversible peripheral dopamine-β-hydroxylase (DβH) inhibitor[1].
Upon intraperitoneal administration to NMRi mice, Etamicastat (100 mg/ kg) leads to a significant reduction of noradrenaline levels (36% control) in heart with concomitant increasing in dopamine levels (850% of control)[2].Etamicastat (50 mg/kg) is rapidly absorbed into the systemic circulation reaching a maximum concentration at 4 h post-administration, representing 29% of total Etamicastat and quantified metabolites, using AUC0-t as a measure of systemic exposure[2].
