Relaxation of human coronary artery and arteria mammaria by K(+)-channel openers.

Abstract:

:Three agents with K(+)-channel-opening activity--nicorandil, bimakalim (EMD 52692), and EMD 56431--were tested for vasorelaxation abilities in human coronary artery and human arteria mammaria. The potency orders were bimakalim = EMD 56431 > nicorandil for relaxation in human coronary artery and bimakalim = EMD 56431 > nicorandil in human arteria mammaria. These data demonstrate that K(+)-channel openers are effective vasorelaxant agents in human coronary artery and human arteria mammaria. Bimakalim and EMD 56431 were more potent than nicorandil, a drug that also activates guanylate cyclase.
