Influence of 15-keto-metabolites and 13,14-dihydro-15-keto-metabolites of PGE2 and PGF2 alpha as well as of 6-keto-PGF1 alpha as a metabolite of PGI2 on aconitine induced cardiac arrhythmia in rats.

Abstract
The 15-keto-metabolites of PGE2 and PGF2 alpha produced an antiarrhythmic effect on aconitine induced arrhythmias in rats. The ED50 values of these metabolites were approximately 2.0 micrograms/kg. The 13,14-dihydro-15-keto-metabolites of PGE2 and PGF2 alpha had no statistically significant antiarrhythmic effect. PGI2 (0.25-1.00 micrograms/kg) produced an antiarrhythmic effect between 15-54% (ED50 0.75 micrograms/kg), whereas 6-keto-PGF1 alpha, a metabolite of PGI2, showed no significant antiarrhythmic effect. The results suggest a participation of 15-keto-metabolites in the antiarrhythmic effects of PGE2 and PGF2 alpha.
