IY-80843, N[2-(2-methoxyphenyl)ethyl]-N'-[4-(lmidazole-4-yl)phenyl] formamidine, is a new potent $H_2-receptor$ anagonist. The potential secondary pharmacologic effects of this agent, on the central nervous and cardiovascular systems were studied. IY-80843 caused ptosis, suppression of locomotion, hypotehrmia, prolongation of sleeping time and hypotensive effects in mice, rats and dogs. These results suggest that IY-80843 affects the funcition of the central nervous and cardiovascular systems in a dose-dependent manner.
