Study Notes
Beta Blockers
- Not commonly used for asthma treatment among common conditions managed by beta blockers.
- Primary mechanism of action involves blocking beta-adrenergic receptors, leading to decreased heart rate and reduced myocardial contractility.
- Abrupt discontinuation of beta blockers can lead to rebound hypertension, tachycardia, and increased risk of angina or heart attack due to sudden overactivity of the sympathetic nervous system.
Asthma
- Common triggers include allergens, respiratory infections, exercise, and environmental factors like smoke and cold air.
- Primary characteristic is airway inflammation and hyperreactivity, which leads to difficulty in breathing, wheezing, and coughing.
- Common medications for managing asthma symptoms include bronchodilators (like albuterol), corticosteroids, and leukotriene modifiers.
