Pharmacodynamics Relative beta1 selectivity is demonstrated by the following: This contrasts with the effect of nonselective beta1 plus beta2 beta blockers , which completely reverse the vasodilating effects of epinephrine. Lopressor has no intrinsic sympathomimetic activity, and membrane-stabilizing activity is detectable only at doses much greater than required for beta blockade.
Animal and human experiments indicate that Lopressor slows the sinus rate and decreases AV nodal conduction.
