A bronchodilator or broncholytic [1] (although the latter occasionally includes secretory inhibition as well) is a substance that dilates the bronchi and bronchioles, decreasing resistance in the respiratory airway and increasing airflow to the lungs.
With this device, a medical liquid (typically epinephrine chloride, used as a bronchial muscle relaxant to reverse constriction). [28] As an alternative to the expensive electrical nebulizer, many people in the 1930s continued to use the much more simple and cheap hand-driven nebulizer, known as the Parke-Davis Glaseptic. [29]
Pulmonary drug delivery is mainly utilized for topical applications in the lungs, such as the use of inhaled beta-agonists, corticosteroids and anticholinergic agents for the treatment of asthma and COPD, the use of inhaled mucolytics and antibiotics for the treatment of cystic fibrosis (CT) and respiratory viral infections, [1] and the use of inhaled prostacyclin analogs for the treatment of ...
MDI canister and actuator components from H&T Presspart. A metered-dose inhaler consists of three major components: the canister, which is produced in aluminum or stainless steel by means of deep drawing, where the formulation resides; the metering valve, which allows a metered quantity of the formulation to be dispensed with each actuation; and an actuator (or mouthpiece) which enables the ...
The symptoms of acute exacerbations are treated using short-acting bronchodilators. A course of corticosteroids, usually in tablet or intravenous rather than inhaled form, can speed up recovery. [1] The IV and oral forms of steroids have been found to be equivalent. [20]
An inhaler (puffer, asthma pump or allergy spray) is a medical device used for delivering medicines into the lungs through the work of a person's breathing. This allows medicines to be delivered to and absorbed in the lungs, which provides the ability for targeted medical treatment to this specific region of the body, as well as a reduction in the side effects of oral medications.
Bronchodilators are considered an important treatment regime for chronic obstructive pulmonary disease (COPD) and are usually used in combination with short acting medications and long acting medications in a combined inhaler. [1] [2]
Pulmonary function testing (PFT) is a complete evaluation of the respiratory system including patient history, physical examinations, and tests of pulmonary function. The primary purpose of pulmonary function testing is to identify the severity of pulmonary impairment. [1]
