What is this medication?
Midodrine is indicated for treatment of hypotension, symptomatic orthostatic.
“ALERT: US Boxed Warning
Because midodrine can cause marked elevation of supine blood pressure, it should be used in patients whose lives are considerably impaired despite standard clinical care. The indication for use of midodrine in the treatment of symptomatic orthostatic hypotension is based primarily on a change in a surrogate marker of effectiveness, an increase in systolic blood pressure measured 1 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.”

Midodrine, Amatine gets converted to an active metabolite, desglymidodrine, which is an alpha1-agonist. This agent increases arteriolar and venous tone resulting in a rise in standing, sitting, and supine systolic and diastolic blood pressure in patients with orthostatic hypotension.
