Salmeterol

Salmeterol 50mcg

Salmeterol is a long-acting beta-2 adrenergic agonist (LABA) used to manage asthma and chronic obstructive pulmonary disease (COPD) by relaxing the muscles around the airways. It aids in relieving symptoms such as wheezing and shortness of breath, making it easier for patients to breathe. Typically administered via inhalation, Salmeterol is intended for maintenance treatment and should not be used as a rescue medication for acute asthma attacks.

Description

Salmeterol is a long-acting beta-2 adrenergic agonist used in the management of asthma and chronic obstructive pulmonary disease (COPD). It works by relaxing the muscles in the airways, leading to improved airflow and relief of respiratory symptoms.

Uses / Indications

  • Asthma (prevention of bronchospasm)
  • Chronic obstructive pulmonary disease (COPD)
  • Exercise-induced bronchospasm (prophylaxis)
  • Symptomatic treatment of respiratory disorders

Dosage and Administration

Adults and children 4 years and older:
50 mcg via inhalation, twice daily (usually one inhalation in the morning and evening).

Note: Dosage may vary based on individual medical condition and doctor’s recommendation.

How It Works (Mechanism of Action)

Salmeterol selectively stimulates beta-2 adrenergic receptors in the lungs. This action leads to the relaxation of bronchial smooth muscle, helping to open the airways and alleviate symptoms associated with asthma and COPD.
