In Vitro	The vasodilator action of C80-1324 (Ipramidil) on coronary vessels is more potent than that of GTN and appears to be biphasic. The increase in coronary flow caused by furoxans as well as by glyceryl trinitrate (GTN) is blunted upon coinfusion of the guanylate cyclase inhibitor methylene blue. NO sign of tachyphylaxis of the vasodilator response is seen upon the repeated or continuous (60 min) application of C80-1324 at a concentration of 1μg/mL,which induces an increase in coronary flow of 67±9% (N=5). Moreover, the vasodilatoreffect of C80-1324 is not different from control when C80-1324 is given after a 60 min preinfusion of 10 μg/mL GTN, i.e. under conditions of nitrate tolerance (P=0.493, N=3). However,when GTN is applied after a 30 min infusion of C80-1324, its dilator response is significantly diminished (P=0.006, N=3). Unlike GTN, Ipramidil concentration independently increases the spontaneous beating rate of the hearts by 10-30 beats per minute and appeared to have a weak positive inotropic effect[1].
