Phentolamine therapy in severe chronic asthmatiform bronchitis.
Continuous phentolamine infusion for 3 days in 6 patients with severe chronic bronchial obstruction produced a marked improvement in subjective well-being and arterial blood gas values. Ventilatory function and pulmonary arterial pressure remained virtually unchanged but a chronic oral corticosteroid therapy could be substantially reduced during 4 weeks of oral treatment with phentolamine 100 mg three times daily.
