- Atenolol Side Effects and Mechanism of Action | Nursing Pharmacology
In this video, you'll learn the side effects of atenolol and atenolol's mechanism of action. This is a super simple way to learn pharmacology faster and easier in nursing school. It will help you understand the critical thinking and WHY behind the side effects, and how Atenolol actually works inside the body.
Mechanism of Action of Atenolol:
Atenolol decreases the blood pressure, heart rate, and cardiac conductivity. It does this by stimulating or occupying beta-1, or myocardial adrenergic receptor sites. These receptor sites are usually occupied by catecholamines like epinephrine and norepinephrine. When they are blocked by Atenolol it blocks their effect. Epinephrine, norepinephrine, and catecholamines usually cause an increase in cardiac conductivity, and since the effects are being blocked, it decreases the conductivity from the SA and AV node, which decreases heart rate and contractility of the heart.
Blocking these receptor sites also decreases the renin release which will decrease blood pressure as well. Since renin cannot be released from the kidneys, it prevents the renin angiotensin aldosterone system which would normally increase blood pressure, but since it is blocked it decreases blood pressure. There are also beta-2 receptor sites located in the lungs. They are usually not affected by atenolol since it blocks the stimulation of beta-1, not beta-2.
Side Effects of Atenolol:
Bradycardia, hypotension, dizziness, weakness and fatigue are common side effects of atenolol.
Atenolol is blocking the beta-1 adrenergic receptor sites in the heart. An easy way to remember side effects of a medication is to consider it working too well, in this case the heart rate and blood pressure have lowered TOO much, leading to those side effects.

Thank you for what you do 🙏
So happy to hear this video was helpful for you, Ben Tol86! You will do GREAT! Thank you for being here, your support means the world to us. 😊
I was on this after experiencing chest tightness from Lisonopril. Atenolol made me feel even worse and drowsy and just bad so my doc put me back on lisonopril. I don’t like the side effects on lisonopril either it makes me dizzy and have headaches I’ve been trying to control my high bp naturally instead by eating healthy it’s usually 147/77. What do you think? Is that a good approach? I don’t want to be a lab rat for bp drugs.

My BP is 150 / 100, i take 50 mg Metoprolol, but after 6 months is still 150 / 100!
Which of those 3, is mostly potent in lowering BP?? Atenolol, Metoprolol or Propranolol???
@nenadcubric2663, they all are going to work the same way, so whichever works best for the specific patient. Focus on the MOA for the class of meds!
What are the common drug interactions ofvthis drug?
Juicy G, any other medication that can affect blood pressure can interact with betablockers, as well as any medications that will affect heart rate. Focus on learning what the medication is doing inside the body, the MOA, and that will make deciphering and critically thinking about interactions much easier!
great job sweetie
Thanks for letting us know you loved this video, oliver falcao! Your support means the world to us. Thank you for being here😊
@@NursingSOS i love your videos, hugs
My doctor put me on this with no monitoring , the side effects combined perfectly with the dabigatran to create a perfect storm , spent a year and half unable to function , with 3 blackouts with fitting which is a side effect of the Atenolol apparently .

Is it true that Atenolol can CAUSE heart failure?
What do you mean mask by mask hypoglycemia ?
Great question, Lise Lopez. It can mask the symptoms of hypoglycemia such as tachycardia, so it is important to be aware of this. I hope that helped clarify it for you. Your support means the world to us. 😁
