Salmefamol and salbutamol. An experimental comparative study of their action on tracheal and bronchial smooth muscles

An experimental comparative study has been undertaken to evaluate the action of salmefamol and salbutamol, two sympathomimetic drugs specific for the beta-receptors, on tracheal and bronchial smooth muscles. Salmefamol showed a more intense, longer-lasting beta-adrenergic activity than salbutamol did.
