Therapeutic indications:

Midodrine hydrochloride tablets are indicated for the treatment of symptomatic orthostatic hypotension (OH). Because midodrine hydrochloride tablets can cause marked elevation of supine blood pressure (BP > 200 mmHg systolic), it should be used in patients whose lives are considerably impaired despite standard clinical care, including non-pharmacologic treatment (such as support stockings), fluid expansion, and lifestyle alterations. The indication is based on midodrine hydrochloride tablets' effect on increases in 1-minute standing systolic blood pressure, a surrogate marker considered likely to correspond to a clinical benefit. At present, however, clinical benefits of midodrine hydrochloride tablets, principally improved ability to perform life activities, have not been established. Further clinical trials are underway to verify and describe the clinical benefits of midodrine hydrochloride tablets. After initiation of treatment, midodrine hydrochloride tablets should be continued only for patients who repo

BLOOD PRESSURE MEASURED ONE MINUTE AFTER STANDING, A SURROGATE MARKER
CONSIDERED LIKELY
TO CORRESPOND TO A CLINICAL BENEFIT. AT PRESENT, HOWEVER, CLINICAL
BENEFITS OF MIDODRINE,
PRINCIPALLY IMPROVED ABILITY TO CARRY OUT ACTIVITIES OF DAILY LIVING,
HAVE NOT BEEN VERIFIED.

CLINICAL PHARMACOLOGY
MECHANISM OF ACTION
Midodrine forms an active metabolite, desglymidodrine, that is an
alpha -agonist, and exerts its actions
via activation of the alpha-adrenergic receptors of the arteriolar and
venous vasculature, producing an
increase in vascular tone and elevation of blood pressure.
Desglymidodrine does not stimulate cardiac
beta-adrenergic receptors. Desglymidodrine diffuse
