Selective development of tolerance to beta-adrenoceptor agonists in skeletal muscle as compared with airway smooth muscle from the guinea-pig

Clinical and Experimental Pharmacology & Physiology

Abstract

1. Guinea-pig were fed with a diet containing terbutaline or placebo for 4--5 days. The trachea, soleus muscle and the extensor digitorum longus (EDL) from these animals were prepared for recording of isometric contractions in vitro. 2. After treatment with terbutaline in vivo, the response of the pilocarpine-contracted trachea to terbutaline and isoprenaline was slightly suppressed with no change in maximum relaxation. 3. After treatment with terbutaline in vivo the maximum depression of the incomplete tetanic contractions of the soleus muscle brought about by terbutaline or isoprenaline was diminished by about 70%. The response of the EDL was also attenuated after previous treatment with terbutaline in vivo. 4. These data indicate a selective development of tolerance to the effects of beta-adrenoceptor agonists in skeletal muscle as compared with tracheal smooth muscle. 5. The present results provide an experimental analogue to the clinical observation that patients being treated with beta-adrenoceptor agonists become tolerant to the tremorogenic rather than to the bronchodilating effect.

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.
