Proventil

Proventil contains the active ingredient Salbutamol, which is a type of medicine known as a short-acting beta 2 agonist. It works by acting on receptors in the lungs called beta 2 receptors. Stimulation of these receptors causes the muscles in the airways to relax, allowing the airways to open.

Proventil is used to treat people with asthma and other chest illnesses. It is particularly prescribed to relieve asthma symptoms, and to prevent asthma symptoms brought on by exercise or other triggers.
