It is marketed for the treatment of bronchoconstriction in patients with asthma, chronic bronchitis or emphysema. The manufacturer claims that it is a ‘logical combination’ offering ‘first line treatment’, but the British National Formulary1 states that compound bronchodilators (including Duovent) ‘have no place in the management of patients with airways obstruction’.
