[Search for new drugs with antiarrhythmic properties among derivatives of adamant-2-ylamides of alkylamidocarbonic acids].

The experiments on white outbred awaken male rats have shown that derivatives of adamant-2-ylamides of alkylamidocarbonic acids exhibit prominent antiarrhythmic (antifibrillatory) effect on the model of calcium chloride arrhythmia. The most pronounced effect was demonstrated by N-[2(adamant-2-yl)aminocarbonylmethyl]-N'-[3-(diethylamino)propyl]-4-nitrobenzamide. This compound was also active on the model of aconitine arrhythmia, which is characteristic of class-I antiarrhythmic agents. It is established that N-[2-(adamant-2-yl)aminocarbonylmethyl]-N'-[3-(diethylamino)propyl]-4-nitrobenzamide has prominent antiarrhythmic activity and is more safe than other antiarrhythmic drugs of class I (lidocaine, ethmosine, novocainamide), class IV (verapamil), and class III (cardiocyclide).
