Over The Counter Rescue Inhalers

Serevent is a medical product produced by GlaxoSmithKline. One dose of Serevent contains: Salmeterol (xinafoate, micronized) - 25 mcg. Other components: trichlorofluoromethane, lecithin, dichlorodifluoromethane.

Pharmachologic Effect of Serevent

Regular intake of the drug provides a persistent improvement in lung function, reducing the severity of the airway obstruction syndrome and nighttime attacks of bronchial asthma. Serevent in therapeutic doses does not have an effect on the cardiovascular system. It is proved that Salmeterol causes a prolonged (up to 12 hours) bronchial dilatation in patients with reversible airway obstruction.

Serevent suppresses early and late reactivity of the bronchi. After a single application weakens the hyperactive response of the bronchi, which indicates an anti-inflammatory and bronchodilating activity.

The onset of action is observed after 5-10 minutes from the moment of inhalation. Broncholytic effect lasts 12 hours.
