Carvedilol mechanism of action
Common Questions and Answers about Carvedilol mechanism of action

Dear p1954
Carvedilol belongs to a class of drugs called beta blockers. It is responsible for inhibition of beta receptors present ubiquitously on the heart muscle. By blocking these receptors, it helps prevent the effects of adrenaline/noradrenaline on the heart thereby maintaining a low heart rate and reducing the energy expended by the heart per beat.
Lisinopril is an ACE inhibitor and the mechanism of the agent is to dilate vessels to reduce hypertension. Metoprolol is in a group of drugs called beta-blockers. Beta-blockers affect the heart and circulation (blood flow through arteries and veins).
Metoprolol is used to treat angina and hypertension for high blood pressure. It is also used to treat or prevent heart attack.
My regimen is Lisinopril and coreg (beta blocker).
The mechanism of action of Campral® (acamprosate calcium) Delayed-Release Tablets in maintenance of alcohol abstinence is not completely understood. Originally, several neurotransmitter systems, including GABA, were investigated for a possible role in Campral's mechanism of action. However, recent evidence suggests Campral's main interaction is with the glutamate system. Chronic alcohol exposure is hypothesized to alter the normal balance between neuronal excitation and inhibition.

The main effect of Carvedilol it is not to low the BP but to reduce the heart rate. Does he take other medication?
It normally takes 3-4 weeks to get used to the medication, anyway, if his body behaves like mine, days of low BP can appear at any moment .... I am on the same dose of it for more than 4 years and right now I am having days in 80/40 range, but I am in a lot of other medications.

Plavix has a unique mechanism of action by blocking the amplification of platelet activation by released ADP, and often used with aspirin to prevent the risk of clots for the first year after DES implant. Plavix and aspirin have different mechanism of action to prevent clots. After a year, plavix is usually discontinue as the risk for clots is decreased, and aspirin is continued long term. The risk of a clot is about 3%.
It recently dropped to 80 over 51 and the doctor took me off of my carvedilol for 2 weeks and said to monitor my blood pressure and call in two weeks. It has been 2 weeks now. I do not know what my heart rate should be at normal and at exertion. I live in a quad level and go up and down a lot of steps to do laundry. I get winded very easily. I want to feel better.
Everyone reacts different on medication, so despite the low dose it could be the medication causing your problems. The Carvedilol is of course especially suspect if you did not have the symptoms before you started taking it.
I suggest that you talk to your doctor about temporarily stop taking it to see if the symptoms subside. A bp of 140/100 for a few weeks is probably not such a problem.
Or you could ask your doctor to switch to another betablocker.
You might ask your Cardiologist to put you on 3.175mg carvedilol twice a day instead of 6.25 twice a day if this is your first experience with it. It is a powerful drug. I started with the 3.175 dose X 2, and it gave me a lot of symptoms such as exhaustion and I do recall a lazy peristalsis (swallowing) issue, but my body got used to it, and he doubled it, then doubled it again.
To help with anxiety, my cardiologist took me off an ACE inhibitor and put me on 12.5 mg of carvedilol twice a day, in addition to 12.5 mg HCTZ. I overcame my anxiety issues with exercise and have been running 3 miles a day for the last six months. I recently had palpitations after running. I went to see the cardiologist just to be on the safe side. He heard a slight murmur, which was new, so he ordered another echo. He decided to put me back on the treadmill. The stress test was normal.

I have recently been prescribed Amlodipine-Benaz 5/10 MG capsules for treatment of hypertension. However, my resting pulse rate has consistently been in the 90's and increasing into the 100's at time, so I have been prescribed Carvedilol to help control the heart rate. My question is, doesn't Carvedilol control hypertension as well...Why should I be taking carvedilol in addition to amliodipine?
I was put on carvedilol, after covid, when I developed heart palpitations. After all the tests were done, they didn't find anything wrong. My doctor told me to stop carvedilol. So I did what he told me. And it has been an awful
3 weeks. I asked if I was having withdrawals from this medicine, He didn't think so or if I was it wouldn't last long. I know that the medicine is out of my system but has my body had time to readjust from it? I was taking 12.5 2X a day for 5 weeks.
Potassium is a chemical element and it is part of the electrolyte that should be in balance with other lytes to adequately conduct an electrical impulse that originates with the sinus node in the right atrium. The mechanism of action is not completely understood, but what is when a voltage (unit of potential for conduction) and electrolyte there will conduction and passage of electrical impluses.
Week 2 was 10mg and week three was the final ramped up dose of 20mg. I was fine on the 5 and 10 mg tablets but felt like crap in the morning after taking the 20mg tablet. The doc allowed me to cut the 20mg tablet in half until our next apt at which time he prescribed Carvedilol 25 mg twice a day. Anyone have any insight as to why he might have done that? Particularly since the 10mg Bystolic tablets seemed to be the “sweet spot” in terms of tolerability.

Ribavirin improves early responses to peginterferon through improved interferon signaling.
Gastroenterology. 2010 Jul;139
The therapeutic mechanisms of ribavirin for hepatitis C are unclear. Microarray analyses have shown that ribavirin increases induction of interferon-stimulated genes. We evaluated viral kinetics, serum cytokine expression, and viral mutagenesis during early stages of peginterferon therapy with and without ribavirin.
Cardiologist understandably wants me on the highest dose of carvedilol for maximum benefit but I just cannot take the doses he wants due to extremely low blood pressure 80s/50s, dizziness, weakness. I've been on 6.25 in am and 12.5 in pm and doing just ok physically on these doses.
Well last night I couldn't get my BP up so I only took 6.25 in the pm. I feel so much better today-bp is up and I've got more energy and am much less foggy.
