Desglymidodrine is the active metabolite of the prodrug midodrine .¹It is formed from midodrine by enzymatic hydrolysis.²Desglymidodrine is an agonist of α₁-adrenergic receptors (α₁-ARs).¹It binds to α₁-ARs (K_is = 9.77, 9.55, and 8.51 µM for α_1A, α_1B, and α_1D-ARs, respectively) and increases intraurethral pressure (IUP) and mean arterial pressure (MAP) by 5 and 20 mm Hg, respectively, in anesthetized dogs at doses of 205 and 250 nmol/kg, respectively.
