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.
