New therapies for postural hypotension.

Patients with deterioration of the autonomic nervous system can have unexpected or even paradoxical reactions to common cardiovascular drugs. For example, patients with severe neuropathy of the peripheral autonomic system can have a pressor response to phenylephrine eye drops and a paradoxical increase in blood pressure (BP) from the antihypertensive clonidine.1 Currently, the only approved the...

Postural hypotension in elderly family practice patients.

Postural hypotension (PH) was investigated in 100 ambulatory patients aged 65 years or older, who were seen in a university family practice clinic. Thirty-one percent had a decrease in systolic blood pressure of 20 mmHg or more, while 16 percent had a diastolic drop of 10 mmHg or more. Twelve percent had a significant drop in both systolic and diastolic blood pressure upon standing. Patients wi...

Postural hypotension induced by atropine sulfate.

Previous tests on the use of large doses of atropine for the treatment of anticholinesterase poisoning have revealed postural hypotension following the administration of 2 mg. of this drug. In this study on 78 normal adult males, the cardiovascular responses to positional change after 2 mg. atropine have been measured and the mechanisms elucidated. Blood pressure response to tilting was normal ...
