The treatment for bronchoconstriction should be aimed at the treatment of bronchoedema, bronchospasm, hypersecretion of mucous and ventilation-perfusion imbalance. Stimulation of β-adrenergic receptors and blockade of α-adrenergic receptors and cholinergic receptors can be considered as the therapeutic approach to bronchoconstriction, and the effectiveness of β-stimulants, α-blockers and anticholinergic compound on bronchospasm has been reported. It has been recognized that new β-stimulants have some different actions, and the effects of β-stimulants on bronchospasm are increased when α-blockers and β-stimulants are used together. Corticosteroids have been employed for the treatment of bronchoedema and hypersecretion of mucous. It has also been observed that β-stimulants and cromeglycate protect against exercise induced bronchospasm and allergen induced bronchoconstriction.
