NCIt definition : A direct-acting prodrug and sympathomimetic agent with antihypotensive properties.
Midodrine is converted to its active metabolite, desglymidodrine by deglycination
reaction. Desglymidodrine selectively binds to and activates alpha-1-adrenergic receptors
of the arteriolar and venous vasculature. This causes smooth muscle contraction and
leads to an elevation of blood pressure. Desglymidodrine diffuses poorly across the
blood-brain barrier, and is therefore not associated with effects on the central nervous
system (CNS).;
