Some observations on the β-adrenoceptor agonist properties of the isomers of salbutamol

摘要: Summary 1 The pharmacological activities of the optical isomers salbutamol have been examined. (–)-Salbutamol was much more potent than (+)-salbutamol on β-adrenoceptors. 2 Both (–)- and showed high selectivity for β-adrenoceptors in bronchial muscle compared to cardiac muscle, this way resembling racemic salbutamol. 3 The use isomeric activity ratio detect differences between receptors examined light results obtained with salbutamol.
