• Nineteen patients with Raynaud's phenomenon in conjunction with progressive systemic sclerosis were given either prazosin hydrochloride (1 mg orally three times a day) or a placebo for eight weeks, after which the treatment procedure was reversed for four weeks. Prazosin was shown to be effective in reducing both the frequency and the severity of vasospasm reported by the patients.
