szalmeterol

Szalmeterol is a long-acting beta-agonist (LABA) medication used to treat asthma and chronic obstructive pulmonary disease (COPD). It works by relaxing the muscles in the airways, which helps to open them up and make breathing easier. Szalmeterol is not a rescue medication and should not be used to treat sudden asthma attacks. It is typically taken in combination with an inhaled corticosteroid for long-term control of respiratory conditions.

The medication is administered via an inhaler and is designed to provide bronchodilation for up to 12 hours. It works by stimulating beta-2 adrenergic receptors in the smooth muscle of the airways, leading to relaxation and widening of the bronchi. This action helps to reduce symptoms such as wheezing, shortness of breath, and chest tightness.

Common side effects of szalmeterol include headache, tremor, palpitations, and muscle cramps. In rare cases, it can cause more serious side effects such as paradoxical bronchospasm, where the airways constrict instead of relax. Due to the risk of serious cardiovascular side effects, szalmeterol should be used with caution in patients with heart disease. It is important to follow the prescribed dosage and not to exceed the recommended frequency of use. Regular medical supervision is advised to monitor its effectiveness and manage potential side effects.
