Summary of Clinical Use
Approved to treat neurogenic orthostatic hypotension (NOH), a condition characterised by a chronic and debilitating drop in blood pressure when rising to a standing position. NOH may be associated with other conditions including multiple system atrophy (MSA), familial amyloid polyneuropathy (FAP), and Parkinson's disease (PD).
Mechanism Of Action and Pharmacodynamic Effects
Droxidopa is a synthetic amino acid precursor of the sympathetic neurotransmitter noradrenaline (norepinephrine) [1]. Noradrenaline is a potent vasoconstrictor acting in the sympathetic nervous system to regulate cardiovascular activity. The enzyme aromatic L-amino acid decarboxylase (aka dopa decarboxylase, DDC; P20711) is responsible for decarboxylation of the prodrug. Drug treatment results in increased blood pressure and improved orthostatic tolerance.
