Inhalers are designed to deliver medication directly to the lungs through a person's own breathing. This may benefit a patient by providing medicines directly to areas of disease, allowing medication to take a greater effect on its intended target, and limit side effects of medications due to localized treatment. Inhalers are used in a variety of different medical conditions with diseases of the lungs and respiratory system being among the most common. These conditions utilize medications designed to decrease airway inflammation and obstruction to allow for easier and less strained breathing. Antibiotic medications have even been developed for inhalers to allow for direct delivery to areas of infection within the lungs. Two of the most common conditions that warrant inhaler therapy are asthma and chronic obstructive pulmonary disease.
