Overview
Brief Summary
This pilot study will assess the efficacy of several sequential pharmacological treatments for patients with Refractory Depression.
Detailed Description
This pilot study will recruit 40 patients with Major Depression and a history of at least two failed prior adequate somatic treatments. In addition to usual physical work-up, all patients will have extensive thyroid testing, and then will receive standard dose Tranylcypromine (i.e., max. 60 mg/d). Non-remitters will have dose increased to max. 120 mg/d if tolerated. Non-remitters to high dose Tranylcypromine will then have Dextroamphetamine added with frequent blood pressure monitoring to max. 40 mg/d. Non-remitters will have Triiodothyronine added to the Tranylcypromine.
