Some clinical pharmacological studies with indoramin, with observations on its therapeutic usefulness.

In the treatment of fifteen patients with essential hypertension, in open trial indoramin caused a mean blood pressure fall from 180/115 mmHg to 159/98 mmHg. No reversal of antihypertensive effect was seen in four patients after additions of the tricyclic antidepressant drug desipramine. Blood pressure did not begin to rise in these four patients for at least 5 weeks after stopping indoramin. The implications of these findings are discussed.
