Abstract

Salbutamol (Ventolin) is a β₂-selective adrenoceptor stimulant which, like other selective agents, is a potent bronchodilator and less likely than isoprenaline to affect the heart.^1–3 To increase selectivity for the airways, salbutamol is often given by inhalation by means of a metered-dose aerosol with fluorocarbon propellant.
