title: A case of primary pulmonary hypertension treated with prazosin and isosorbide dinitrate.
abstract: Successful vasodilator therapy of a 27-year-old woman with primary pulmonary hypertension is described. Prazosin 2 mg, orally in combination with isosorbide dinitrate 10 mg, sublingually caused a marked fall in pulmonary vascular resistance. Pulmonary hemodynamics reevaluated after 3 months of combination therapy with prazosin 1 mg qid and isosorbide dinitrate 5 mg qid showed sustained improvement. Therefore, in selected patients with primary pulmonary hypertension, this combination therapy can be used.
