Common Questions and Answers about Metoprolol beta 1 beta 2

Beta-1 and Beta-2. Those in the heart are mostly Beta-1; those in the lungs, mostly Beta-2. Beta-blockers come in 2 forms: selective and non-selective. Selective beta-blockers, such as metoprolol, act primarily on the Beta-1 receptors in the heart. Non-selective beta-blockers, such as propranolol act on both types of receptors, in both heart and lungs. Propranolol and other medicines in its class are capable of evoking bronchospasm in people with asthma.
Still have the Afibs, mostly at night, still take Flecainide twice a day and Warfarin. Cut my Metoprolol to 1/2 pill daily as I hated not b eing able to get my HR up when I am jogging, But the last few days my BP has been sky-high. 193/100 was the highest, 141/.70 the lowest. Nobody knows why. I recently changed from Diovan to another BP med, but that was 6 weeks ago. Waiting on bloodwork to see if the high BP has another cause.
Hi tom_h, Metoprolol is a cardio-selective beta-blocker, or in the the "selective" class of beta blockers. It only blocks on cardiac receptors (beta-1), so the side effects are limited.
Propranolol and Sotalol are non-selective beta blockers so they block all adrenaline receptors, (beta-1 and beta-2), so a lot more side effects on things that depend on adrenaline.
I neglected to say that I DO have cold hands and feet and I DID feel like I was getting depressed. I lost my husband to cancer 2 1/2 years ago and had been dealing with it fairly well. Since being on the Metoprolol I also have been having trouble getting out of bed.
I am in the process of weaning off, am down to 25 mg / day. Maybe I should call my doctor and see what he thinks I should do.
But more important, with AFib you need to guard against the formation of blood clots. A simple aspirin a day (or 1/2 or a low dose) with a meal (I take my 1/2 aspirin with breakfast every morning). If you have other clot risk factors (you didn't give me any, you age is on the margin of being a risk factor) you may need a prescription for an anticoagulant.
I have been in and out of AFib for years, and was a runner until April of 2007 when I could not be converted back to NSR.
I've been taking 25 mg of metoprolo a day (1/2 pill twice daily) just for some minor issues with PVCs. After several months I got hives and some food sensitivity that is evidently a side effect, so I decided to stop.
My cardiologist seemed to think this is a low enough dose that I could just stop cold if I wanted to, but I thought I'd see what folks thought, if I should taper off.
Hyperkalemia secondary to beta-adrenergic receptor blockade can occur in 1% to 5% of patients and is more likely to occur in non-cardio-selective beta-blockers versus cardio-selective beta-blockers. Underlying cause can be excessive potassium intake, disturbed cellular uptake of potassium, or impaired renal excretion of potassium.
My system is periodically tested to monitor renal excretion of potassium as well as liver functionality.
what is best beta blocker for running and racing with psvt? my doctor put me on metoprolol......I know very little about this but am hearing a lot of athletes are on atenolol anybody know anything about this or is this just individual thing?
can I drink the juice of 1 grapefruit a day, if I am taking metoprolol and fosinopril for blood pressure? My blood pressure is completely controled.
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).
I have been on metoprolol 25mg for two 1/2 years. Then my doctor put me on metoprolol er 50mg. I have been having shortness of breath and minor chest discomfort; i'm only 45 years old and i want off of this medication totally. Has anyone ever wean themselves off of this medication with no problems? If so, how did you do it? Any advise is helpful to me. Thank you.

It seems to me if you have high blood pressure the medication should be taken regularily and not as needed. I don't know the effect it has on chest pain.
Your question leads me to wonder if you got your prescription from a medical doctor. It seems that person would tell you how to transition.
I hope you are not getting meds off the "web" and self-testing.
I haven't looked up, but isn't sotalol and atenolol anti-arrhythmia drugs,or are they indeed just another beta blocker - like metoprolol (maybe the ending "lol" is the key to the answer - I'm still learning the extensive drug names).
Metoprolol caused me hair loss....Bystolic has slowed it down somewhat....
In a word "Yes". The bigger question is: can you remember to take it twice a day...at the proper time? If so, then you can ask your doctor for the chance to try it.
Hello....I hope all of you can help. I feel like I'm in beta blocker hell. I've been bed ridden from a car accident for the last 20 yrs. After a recent endoscopy procedure I started getting horrible pounding tachycardia that day. I:m already in a weakened state from being inactive and bedridden. Right after the procedure a week ago...I started getting constant tachycardia almost 24hrs a day. It gets worse when i eat. They hospitalized me for 1 day...did an ECHO....it was normal.
After my heart attack and surgery I was put on lopressor and amiodarone for heart irregularities. Because of the bad side effects of amiodarone I was taken off of that and also my beta blocker got changed. My beta blocker was changed to metoprolol tartate ..25mg twice a day. It didn't take long before I noticed that I was having pvc's again (hadn't had while on lopressor and amiodarone) and it has progressed to where it is noticeable every day ......all day long.
My cardio gave me some samples of 10 mg coreg to take once a day and a prescription to fill if the side effects from the metoprolol do not get any better. The side effects from the metoprolol have gotten a little better - I don't feel as exhausted, though as I type this my heart rate is 52 bpm. Plus when I go walking I can't get my heart rate above 95 bpm. Does any one have any comments on the pros and cons of carvedilol versus metoprolol?
As far as I understand Metoprolol is a Beta Blocker, its main effect is to reduce your heart rate and therefore reduce the volume of blood per minute to be pumped but I do not think that it affects the EF.
If you has a history of HBP, chances are that you have some hypertrophy of the left ventricle, this can be the reason for the reduction.
Anyway your value is in the normal limit. Do you have a previous value?
ve been dealing with tachycardia for some time now. It comes and goes. I found that 50mg of Metoprolol twice a day would mostly control it, but as a 33 year old man, I began to notice major erection issues since being on it. Talked to my doctor, they want me to start 120mg a day of Diltiazem. I'm a little nervous about it, but they assured me it's no more potent a medication. And they said it's much better in terms of no side effects on sexual side.
