Does dihydroergotamine improve venous distensibility and blood pressure in a patient with severe idiopathic orthostatic hypotension?
Does dihydroergotamine improve venous distensibility and blood pressure in a patient with severe idiopathic orthostatic hypotension?
Dihydroergotamine may be difficult to use in severe idiopathic orthostatic hypotension due to denervation hypersensitivity causing recumbent pressor responses.
No takes yet. Share an insight, caveat, or question.
DHE may provoke recumbent hypertension in severe orthostatic hypotension; single case leaves open utility in milder or alternative settings.
Bellamy et al. (1984) studied this question.
