Aninhaler is a device used to inhale medicinal material. It is an emergency medical treatment for asthma. An inhaler takes the drug directly into the lungs. Also, patients using an inhaler no longer need to take a bigger dose of medicine, whether a tablet or liquid taken by the mouth. Inhalers are less likely to cause any side effects because the drugs do not mix with the bloodstream when inhaled by the nose.
Proventil
The bronchodilator Proventil is a common emergency prescription medication used to treat asthma. During an asthma attack, the smooth muscle layer goes into spasm, narrowing the airway. Proventil quells these airway-closing spasms in the bronchial walls, says Drugs.com. It belongs to a specific class of medications called beta-adrenergic receptor agonists, which stimulate the beta-receptors, sense organs that receive and process nerve signals on cell surfaces to widen or dilate air passages in the lungs. Proventil is administered in inhaled form to prevent asthma attacks and improve lung functions.
Ventolin
Ventolin, a brand name of salbutamol, a beta-adrenergic receptor agonist, can be prescribed in an emergency to prevent and relieve bronchospasm in people with reversible obstruction airway diseases, usually asthma. It corrects the constriction of the air passages of the lungs caused by spasmodic contraction of the bronchial muscles. Ventolin, being a short-acting inhalation aerosol, can quickly open constricted air passages within the lungs and ease any breathing disorders within minutes, says eMC Medical Guides. Ventolin is meant to prevent asthma attacks caused by triggers such as dust, pollen, pets and exercise.
Xopenex
Xopenex also is a beta-adrenergic receptor agonist, similar to Proventil and Ventolin. It works by relaxing the contractive muscles in the walls of the lungs, allowing normal breathing and relieving wheezing. It is important that the patients use a nebulizer that reduces the liquid Xopenex into a fine spray so that it can be inhaled directly into the lungs. People shouldn't use Xopenex without consulting a health expert if they have pre-existing medical conditions such as heart disease, hypertension, diabetes and an overactive thyroid or hyperthyroidism, according to Drugs.com.
