For treatment of respiratory disorders inhalation therapy is the preferred administration route for efficacy and safety. Inadequate inhaler instruction and poor inhaler technique can mitigate drug efficacy and can be a major cause of poor disease control.
Being alert to patients’ prescription use will enable you to gauge whether a patient is concordant with treatment – look for regular preventer use, ED attendances and frequent requests for relievers may indicate poor control.
