| Abstract: | Prostacyclin (PGI2) produces an antiarrhythmic effect on aconitine induced arrhythmias in rats. The ED50 of PGI2 was 0.7 microgram/kg and the maximum antiarrhythmic effect 54 per cent. The equi-effective doses of PGE2 and PGF2alpha were higher (ED50 of PGF2alpha = 1.2 microgram/kg, ED50 of PGE2 = 2.7 microgram/kg). However, PGF2alpha and PGE2 had a maximum antiarrhythmic effect of 80 per cent in this model. |
