Abstract
The responses of eccrine sweat glands to intradermally injected phenylephrine were studied in six healthy male volunteers in two experiments carried out in February and June. Phenylephrine (10(-7)-10(-2) M, 50 microliters) had no consistent effect on sweat gland activity during February, but evoked dose-related increases in sweat gland activity during June. Responsiveness to phenylephrine could be antagonized by prazosin (10(-5) and 10(-4) M) added to the injection solution.
