Salbutamol, also known as albuterol and sold under the brand name Ventolin among others, [1] is a medication that opens up the medium and large airways in the lungs. [8] It is a short-acting β 2 adrenergic receptor agonist that causes relaxation of airway smooth muscle. [8]
While the use of inhaled steroids and long-acting beta2‑adrenergic agonists are recommended for the resulting improvement in control of symptoms of asthma, [10] concerns have been raised that salmeterol may increase the risk of death due to asthma, and this additional risk is not reduced by the addition of inhaled steroids.

Taken 15 to 20 minutes ahead of time, these medications can also prevent asthma symptoms triggered by exercise or exposure to cold air. Some short-acting β-agonists, such as salbutamol , are specific to the lungs; they are called β 2 -adrenergic agonists and can relieve bronchospasms without unwanted cardiac side effects of nonspecific β ...

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.
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 ...
COPD causes airflow limitations in the lungs because of inflammation. Smoking is the main risk factor but inhalation of toxic and harmful particles and gases can also cause the disease. The symptoms are abnormal mucus production, inflation in the lungs that causes airflow limitation, abnormal gas exchange and pulmonary hypertension.
