Allergic immunotherapy has been shown to be effective for _________ than asthma.
allergic rhinitis and conjunctivitis
Systemic glucocorticoids are used only for __________.
management of severe asthma and asthma exacerbations
ß-agonists stimulate ________ in the lungs that leads to ________.
ß2 adrenergic receptors; bronchodilation and decreased mucus secretion
How do anticholinergic agents (like tiotropium) work?

induce bronchodilation and inhibit inflammation
