desglymidodrine

Desglymidodrine is a metabolite of midodrine, a medication used to treat symptomatic orthostatic hypotension. Midodrine is a prodrug, meaning it is converted in the body into its active form. Desglymidodrine is the primary active metabolite of midodrine. Following oral administration, midodrine is rapidly hydrolyzed by esterases in the blood and tissues to form desglymidodrine. This conversion is nearly complete.

Desglymidodrine is a direct-acting alpha-1 adrenergic agonist. It works by constricting blood vessels, which increases blood pressure. This effect is particularly beneficial for individuals who experience a significant drop in blood pressure upon standing, a condition known as orthostatic hypotension. By increasing peripheral vascular resistance, desglymidodrine helps to maintain blood pressure and alleviate symptoms such as dizziness, lightheadedness, and fainting.

The pharmacokinetic profile of desglymidodrine is characterized by rapid formation after midodrine administration and a relatively short half-life. This necessitates frequent dosing of midodrine to maintain therapeutic levels of desglymidodrine. While desglymidodrine is the active moiety, it is typically referred to as midodrine when discussing the medication as a whole, as midodrine is the administered prodrug. The efficacy and safety of midodrine therapy are attributed to the pharmacological actions of desglymidodrine.
