Sympathomimetics, such as Ephedra alkaloids, are associated with an increased incidence of intracerebral hemorrhage believed to be secondary to concomitant elevations in blood pressure. We hypothesized that sympathomimetics decrease platelet aggregation. Reductions in epinephrine-mediated platelet aggregation by ephedrine, phenylpropanolamine, and racemic amphetamine were determined by measuring the changes that these sympathomimetics induced in the optical density of platelet-rich plasma from… Expand
