1. What is a sympathomimetic agent?

one that mimics the effects and stimulates the sympathetic nervous system

2. What is the drug of choice for a status asthmaticus and anaphylaxis rxn?

epinephrine

3. What are the mechanisms of epinephrine?

nonselective adrenergic stimulant that induces bronchodilation, decreased bronchial secretions and the release of inflammatory mediators

4. How is epinephrine delivered and what is the half life like?

delivered IM, IV, or inhaled (not PO) and it is relatively short acting

5. What is the general effect of the B2 selective agonists?

work to be relatively selective for the B2 receptors (but may affect B1 in high doses), with local administration to decrease systemic effects

6. What are the two types of B2 agonists? what are they used for?

short acting (accute attacks) and long acting (prevent attacks)

7. What is albuterol?

a fast acting, non catelcholamine B2 selective agonists t

8. What are the indications for albuterol?

asthma and COPD -- used for acute attacks due to fast action

9. What are the routes of administration of albuterl?

aerosol, tablets and syrup (pediatric)

10. What is a drug-drug interaction of albuterol?

concurrent with MAOI inhibitors can cause enhanced effects and toxicities
