Introduction: What is Salmeterol?

Salmeterol is a long-acting beta2 adrenergic agonist (LABA) primarily used in the management of respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). It works by relaxing the muscles in the airways, making it easier to breathe. Salmeterol is not a rescue medication; instead, it is used as a maintenance treatment to help control symptoms and prevent asthma attacks.

Uses of Salmeterol

Salmeterol is approved for several medical uses, including:

• Менаџмент астме: It is used as a long-term control medication for asthma in patients aged 4 years and older as an adjunct to ICS, not standalone.
• Хронична опструктивна плућна болест (ХОБП): Salmeterol helps improve lung function and reduce symptoms in individuals with COPD.
• Бронхоспазам изазван вежбањем: It is approved for prevention in patients aged ?4 years, but not for acute treatment.

Како то функционише?

Salmeterol works by stimulating beta2 adrenergic receptors in the smooth muscle of the airways. When these receptors are activated, the muscles relax, leading to dilation of the airways. This process helps to alleviate symptoms such as wheezing, shortness of breath, and chest tightness. Unlike short-acting bronchodilators, Salmeterol provides prolonged relief, lasting up to 12 hours.

Дозирање и администрација

The standard dosage of Salmeterol varies based on the condition being treated:

• За астму: 50 mcg twice daily for adults/adolescents and children ?4 years via DPI (e.g., Serevent Diskus); consult product labeling for MDI.
• За ХОБП: Adults usually take 50 mcg twice daily.

Salmeterol is administered through a metered-dose inhaler (MDI) or a dry powder inhaler (DPI). It is essential to follow the prescribed dosage and not exceed the recommended frequency.
