Midodrine, also known as 3,6-dimethoxy-β-hydroxy-N-aminoethanonyl-2-phenylethylamine, is a substituted phenethylamine derivative. [4] Midodrine is an odorless, white, crystalline powder, soluble in water and sparingly soluble in methanol. [19] Midodrine's experimental log P is -0.5 and its predicted log P ranges from -0.49 to -0.95.
Severe drops in blood pressure can lead to fainting, with a possibility of injury. Moderate drops in blood pressure can cause confusion/inattention, delirium, and episodes of ataxia. Chronic orthostatic hypotension is associated with cerebral hypoperfusion that may accelerate the pathophysiology of dementia. [5]
Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
Dementia, however, can present early in its disease course with depressive symptoms, meaning that this association could actually be reflecting that dementia causes late life depression. [23] Studies that have directly tried to determine whether depression is an independent risk factor for dementia have led to inconclusive results.
Postural orthostatic tachycardia syndrome (POTS) is a condition characterized by an abnormally large increase in heart rate upon sitting up or standing. [1] POTS is a disorder of the autonomic nervous system that can lead to a variety of symptoms, [10] including lightheadedness, brain fog, blurred vision, weakness, fatigue, headaches, heart palpitations, exercise intolerance, nausea ...
A systematic review and meta-analysis conducted on clinical trials comparing the clinical use of droxidopa and midodrine have found that midodrine was more likely to cause supine hypertension than droxidopa in patients with NOH. Midodrine was also found to be slightly more effective at raising blood pressure but not statistically significantly ...
Lactic acidosis is commonly found in people who are unwell, such as those with severe heart and/or lung disease, a severe infection with sepsis, the systemic inflammatory response syndrome due to another cause, severe physical trauma, or severe depletion of body fluids. [3]
Such dose can be repeated after 20 minutes. After the bolus, a continuous intravenous infusion can be given at 5 to 10 mg per hour. For those with underlying renal impairment or severe heart failure, up to 160 to 200 mg bolus dose can be given. [13]
