Pharmacological basis for duration of effect: formoterol and salmeterol versus short-acting beta 2-adrenoceptor agonists
(1996) In Lung 174(1). p.1-22- Abstract
- The mechanisms behind the long duration of bronchodilating action of the beta 2-adrenoceptor agonists formoterol and salmeterol are only partially understood. This review compares pharmacological characteristics of long-acting versus short-acting beta 2-adrenoceptor agonists in human and animal airways. Based upon the reviewed evidence, it is concluded that for beta 2-adrenoceptor agonists, long duration of action may depend upon several factors. Both formoterol and salmeterol display a higher lipophilicity and have a higher affinity, selectivity, and potency than most short-acting agonists at the beta 2-adrenoceptor. Of these factors, lipophilicity may prove to be one of the most important ones by determining the amount of drug entering... (More)

Of these factors, lipophilicity may prove to be one of the most important ones by determining the amount of drug entering into the cell membrane in the vicinity of the beta 2-adrenoceptor. However, the receptor affinity, maximal relaxant effect (efficacy or intrinsic activity), potency, and receptor selectivity may also be of importance in determining how much beta 2-adrenoceptor agonist must remain at the receptor for sustained action.
