Comparison of Antifibrillatory Potency of Certain Antimalarial Drugs with Quinidine and Procaine Amide

Abstract
Using the method of electrical threshold of fibrillation in intact cats, it was found that quinacrine, chloroquine and pentaquine are very effective antifibrillatory agents. However, chlorguanide and Daraprim are ineffective. The significance of these findings is briefly discussed.
