title: Repeated treatment with SA4503, a selective sigma1 receptor agonist, up-regulates alpha-adrenergic system. a behavioral study.
abstract: The obtained results indicate that SA4503, a selective sigma1 receptor agonist, given repeatedly (but not acutely) enhanced the effects of phenylephrine, alpha1-adrenoceptor agonist, and clonidine (stimulating the postsynaptic alpha1-adrenoceptors at high dose) in behavioral models (hyperexploratory activity in rats and aggressiveness in mice, respectively).
