Abstract

The ability of beta-adrenoceptor agonists to reduce the fusion of incomplete tetanic contractions of the soleus muscle of the cat has been used previously as a model to assess the potential tremor producing effect of sympathomimetic bronchodilators. The ability of (-)-isoprenaline, (-)-adrenaline, (+/-)-soterenol and (+/-)-quinterenol to depress incomplete tetanic contractions of the soleus has now been assessed using cumulative administration of the amines. The method quickly produced accurate and reproducible dose-response curves. It is particularly useful for evaluating the potency of long-acting compounds.

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.
