What is the difference between albuterol and alupent (metaproterenol) for asthma?

What is the difference between albuterol and alupent (metaproterenol) for asthma?

Similar: Both are medications that are used as bronchodilators -- that is quick acting medications for asthma symptoms. Albuterol is probably the most commonly used. Haven't not seen Alupent (metaproterenol) used fro years. ...Read more

Receptor (Definition)

An organ, cell or molecule that accepts an outside signal and causes an internal change. Eyes receive light, touch receptors send messages to the brain when stimulated by pressure and estrogen receptors bind Estradiol causing responses of normal breast, ovary and uterus cells to rising and falling levels of the female steroid hormones. Most of the time "receptor" refers to one ...Read more

I'm taking a new asthma medication described as specific to beta 2 receptors. What does this mean?

I'm taking a new asthma medication described as specific to beta 2 receptors. What does this mean?

Beta-2 agonist: You are likely taking albuterol, or some form of it, which specifically targets the beta-2 receptors in the lungs for it's intended effects. These specific receptor medications are intended to treat disease of the lungs, without cross-reacting to beta-1 receptors in the heart. Hope this helps. ...Read more

Selective beta blockers instead of non selective for asthma patients? Or are both bad?

Selective beta blockers instead of non selective for asthma patients? Or are both bad?

Selective may be OK: Selective beta 1 blockers are are tolerated by most asthmatics at lower doses. Non-selective beta blockers are contra-indicated in asthmatics because they block the beta2 receptors in the airways, leasing to broncho-constriction. Even non-selective applied to the eyes (for glaucoma) can cause asthma attacks or poorer control. High doses of beta1 may rarely cause similar worsening of asthma. ...Read more

Is a cardioselective beta blocker safe for someone with mild asthma? It is to treat pots when standing.

Is a cardioselective beta blocker safe for someone with mild asthma? It is to treat pots when standing.

Maybe: It's highly individualized and depends on the severity of your asthma and dose of the drug being used. Some people will tolerate it and some won't. Even those who do may have a worsening of their asthma following a respiratory infection months or years hence. You can always try it, stop it if necessary, and use a bronchodilator till back to baseline. ...Read more

Can I take beta blocker if I have asthma ?

Can I take beta blocker if I have asthma
?

Not advised.: It is not a good choice for asthma. If there is no other option, you may ask your doctor to try a low-dose cardio-selective blocker. One study showed that although the lung function did decrease slightly when people with asthma are treated with a selective beta blocker, their bronchodilator response actually improved. I have not seen this study confirmed however. ...Read more

How long does a beta blocker stay in your system ? I took atenolol for a month , 25 mgs twice a day . I discontinued it 3weeks ago, asthma flared up !

How long does a beta blocker stay in your system ? I took atenolol for a month , 25 mgs twice a day . I discontinued it 3weeks ago, asthma flared up !

Half life: Atenolol half life is about 6-7 hours. A few of days after stopping the medication, almost all of it is cleared. After 3 weeks, there should be no trace of this medication in your system. ...Read more

How to improve hypertension while using beta agonist medications to control asthma?

How to improve hypertension while using  beta agonist  medications to control asthma?

Other BP meds: There are many alternative families of BP meds that can be used in asthmatic patients. Even if one has a medical condition where a beta blocker is the best choice, there are some of that family that affect asthma less than others. Discuss options with fp/allergist/ pulmonologist/internist. ...Read more

Asthma bad since using bystolic (nebivolol). Only beta blocker not allergic to. Should i continue the bystolic (nebivolol)? Bp was 200/120 now its only 131/66. Renal pt.

Asthma bad since using bystolic (nebivolol). Only beta blocker not allergic to. Should i continue the bystolic (nebivolol)? Bp was 200/120 now its only 131/66. Renal pt.

Hypertension: Would talk with your doctor(s) about this. There are other classes of drug such as calcium blockers which might not cause problems with your asthma. Your doctors will understand more of your whole picture and can advise you more specifically to your problems. ...Read more

Is it safe to take beta blockers for pvcs if alsi have asthma?

Maybe not: B-blockers result in bronchconstriction, meaning the airways tend to close whereas b-agonists tend to bronchodilate, or open the airways. So, b-blockers may result in airway closure leading to acute asthma symptoms. (note: even b-blocker eye drops can have this effect!) some b-blockers do this to a lesser extent than others so check with your doctor first. ...Read more
