Definition
Noun: - A synthetic sympathomimetic amine used as a bronchodilator to relax and open air passages in the lungs, primarily in the treatment of reversible airway obstruction such as asthma, emphysema, and chronic bronchitis.
Usage
Metaproterenol is a medication administered to relieve bronchospasm. It is typically used on an as-needed basis for quick relief of acute symptoms like wheezing and shortness of breath.
Examples
- The doctor prescribed metaproterenol in an inhaler form for use during asthma attacks.
- Before exercise, she used her metaproterenol to prevent exercise-induced bronchoconstriction.
- Metaproterenol can cause side effects like nervousness or a rapid heart rate.
Advanced Usage
- Therapeutic Class: Metaproterenol is classified as a beta-2 adrenergic receptor agonist. It selectively stimulates receptors in the lungs to cause bronchodilation.
- Route of Administration: It is available for administration via oral inhalation (metered-dose inhaler) or as an oral syrup/tablet, though the inhaled form provides more direct action with potentially fewer systemic side effects.
