Mode of action of inotropic agents: Introduction.

Inotropic action of hexamethonium.

The positive inotropic action of hexainethoniuin in hypodynamic and freshly prepared papillary muscles of the cat and the hypodynamic heart-lung preparation of the dog has been demonstrated. Within certain limits, there exists a proportionality between the concentration of hexamethonium and the magnitude of the inotropic response. In both preparations results have been obtained which indicate t...

Classification of positive inotropic agents.

Although there is increasing recognition that all inotropic agents are not alike, they continue to be viewed in the generic sense because of the lack of a classification system. Analogous to the classification system proposed for the antiarrhythmic agents over 20 years ago, a classification system is proposed that categorizes inotropic agents according to their mechanisms of action. Agents are ...

Mode of action of new anti-arrhythmic agents.

Propranolol, diphenylhydantoin and tetrodotoxin showed inhibitory or removal effects on fibrillation induced in isolated rabbit atrial muscle strip. Depending upon methods of induction of fibrillation, effects of these drugs were different. The mode of their action seemed to be due to following electrical natures of each drug in its effective dose. Diphenylhydantoin decreased rate of rise and a...
