Ch. 5: Cardiovascular and Renal Systems Drugs

Question 1

Beta-Blockers-
Beta 1 Antagonist (Beta-Blocker)

Answer 1

A class of drugs that block beta-adrenergic receptors, reducing heart rate and blood pressure.

Selective Beta 1 Antagonist: Metoprolol, Atenolol, Esmolol
Non-Selective Beta 1 Antagonist:

Propranolol, Nadolol, Timolol
Mixed Alpha 1 and Non-Selective: Carvedilol, Labetalol

Question 3

Beta-2 Receptors, location and function?

Answer 3

Location: Found in places like the lungs, blood vessels, and muscles.

Function: When Beta-2 receptors are activated, they relax smooth muscles (such as in the lungs) and help with dilation (opening up airways). This is why Beta-2 agonists (like certain asthma medications) help open up the airways, making it easier to breathe.

Easy Explanation: Think of Beta-2 as a “muscle relaxer.” It helps open up airways in the lungs or widen blood vessels.

Question 4

Key differences between b1 vs b2- blocker?

Answer 4

Beta-1 is mainly involved in heart function (increasing heart rate and strength).

Beta-2 is mainly involved in lungs and blood vessels (helping open airways and relax muscles)

Question 5

Beta-1 Blocker meds

Answer 5

(like metoprolol) are used to slow down the heart rate or lower blood pressure by blocking these receptors.

Question 6

Beta-2 agonists meds?

Answer 6

(like albuterol) are used in inhalers for asthma to open up the airways and help you breathe easier.

Question 7

beta 1 vs beta 2 in short?

Answer 7

Beta-1 = heart (increases heart rate and force).

Beta-2 = lungs and muscles (relaxes muscles, opens airways).
