What drug causes orthostatic hypotension?
What drug causes orthostatic hypotension?
Common drugs that cause orthostatic hypo tension are diuretics, alpha-adrenoceptor blockers for prostatic hypertrophy, antihypertensive drugs, and calcium channel blockers. Insulin, levodopa, and tricyclic antidepressants can also cause vasodilation and orthostatic hypotension in predisposed patients.
Do ACE inhibitors cause orthostatic hypotension?
Several medications, including antidepressants, and drugs used to treat Parkinson’s disease, high blood pressure, and erectile dysfunction may lead to orthostatic hypotension. Examples of these medications include beta blockers, calcium channel blockers, angiotensin-converting enzyme (ACE) inhibitors, and diuretics.
What qualifies as orthostatic hypotension?
Orthostatic hypotension is a physical finding defined by the American Autonomic Society and the American Academy of Neurology as a systolic blood pressure decrease of at least 20 mm Hg or a diastolic blood pressure decrease of at least 10 mm Hg within three minutes of standing.
How do you stop orthostatic hypotension?
Orthostatic hypotension treatments include: Lifestyle changes. Your doctor may suggest several lifestyle changes, including drinking enough water; drinking little to no alcohol; avoiding overheating; elevating the head of your bed; avoiding crossing your legs when sitting; and standing up slowly.
How do Diuretics cause orthostatic hypotension?
Diuretics or water pills used to control high blood pressure are also another cause of a decreased amount of fluid in the body. Blood loss and other causes of anemia decrease the number of red blood cells that carry oxygen in the bloodstream, and this may lead to the symptoms of orthostatic hypotension.
Why does BP drop when you stand up?
When you stand up, gravity causes blood to pool in your legs and abdomen. This decreases blood pressure because there’s less blood circulating back to your heart. Normally, special cells (baroreceptors) near your heart and neck arteries sense this lower blood pressure.
What heart conditions cause orthostatic hypotension?
Patients with heart valve disorders, heart failure, and heart attack may all experience orthostatic hypotension. Disorders of the nervous system may also cause orthostatic hypotension. Examples include Parkinsonism, amyloidosis, and Shy-Drager Syndrome (or multiple system atrophy).
