Does salbutamol has similar efficacy to terbutaline in treatment of asthma?

Does salbutamol has similar efficacy to terbutaline in treatment of asthma?

Yes and no: Both are indeed bronchodilators. However, terbutaline works a bit differently than salbutamol. Also, salbutamol is a long acting preparation, whereas terbutaline is not. Salbutamol is used as an inhaled medication, where terbutaline can be given as a shot. ...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

Im using following tablets for my asthma treatment
1)ruptadine&montelukast 
2)ambroxol, terbutaline&etofylline
3)sertalin
r they safe for long term use?

If ok'd by the FDA: Any medication can have bad side effects in a few people. Medications that are approved for long term use by the fda are considered safe, but doctors and patients still keep an eye out for undesired reactions. Also, "long term" may mean 6 weeks, 6 months, 6 years, etc... Doctors on healthtap are U.S. Doctors, so generally do not have information on foreign medications. ...Read more

Asthma attack every night for 1 week. Taking bricanyl (terbutaline) tablet and ventolin nebule for nebulizing. Is this safe?

No: Meds you are taking treat symptoms but not root cause, inflammation in airways. Suspect something where you sleep is trigger (dust mites). Dust mite cover for mattress and pillow important. Wash bed linens in hot water and dry in hot dryer each week helpful. See healthcare provider for eval. Daily peak flow monitoring with plan for when levels low important. Use of inhaled steroid basis tx. ...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

Can someone take beta blocker medications if they also have asthma?

Can someone take beta blocker medications if they also have asthma?

Yes: Beta blockers block the beta 1 receptor on the heart. Some are not specific for that and also block the beta 2 receptor in the lungs which can worsen asthma. Choosing a selective beta 1 blocker (metoprolol and atenolol are probably the most commonly used) at the appropriate dosage eliminates this problem. ...Read more

Why don't we use beta blockers on patient with asthma and coronary disease?

See below: Because most asthma patients are on beta agonists (like albuterol) which open bronchial airways by relaxing smooth muscle in the airways. Beta blockers do the reverse and would cause bronchoconstriction and thus worsen asthma or as least block the effects of the beta agonists. ...Read more

What's to be expected? Might ventolin work at all if you have an asthma attack whilst taking beta blockers?

What's to be expected? Might ventolin work at all if you have an asthma attack whilst taking beta blockers?

Less so: Ventolin may still work but would likely be less effective. It is also important to choose a cardio-selective beta blocker if there is no other alternative. One study showed that taking a cardio-selective beta blocker reduced the fev-1 (the one-second airflow which is reduced in airway obstruction) by about 7% but made the lung more responsive to bronchodilators . Avoid beta blocker if possible. ...Read more

Mild night asthma, Given Dulera (formoterol and mometasone). seem to be better options for asthma maintenance meds, please recommend. Need to avoid interaction with Beta Blockers?

Mild night asthma, Given Dulera (formoterol and mometasone). seem to be better options for asthma maintenance meds, please recommend. Need to avoid interaction with Beta Blockers?

Or avoid b blockers: unless b1 selective, which should be used with caution too, also Delera is a combo medicine , contains Inhaled CorticSteroid, in adiition to a long acting beta agonist (LABA) which are better avoided, if not extremely needed while on B blockers, generally those LABAs better be discontnued once asthma is controlled with other maintenance meds, please talk again to your doctor, take care ...Read more

I've mild asthma, under control. Why shouldn't I take beta blockers to control mvp without regurgitation? I'm taking diltiazem.

I've mild asthma, under control. Why shouldn't I take beta blockers to control mvp without regurgitation? I'm taking diltiazem.

Aggravates asthma: Most asthmatics have a form of albuterol inhaler (e.g. Proair, ventolin, proventil) for rescue use and many have salmeterol or formoterol inhalers. All these medications stimulate what is called the "beta-adrenergic" receptor (beta receptor for adrenalin) which causes the muscles around the broncial tubes to relax. Beta-blockers block the beta-receptors making asthma worse in many individuals. ...Read more

Does anticholinergic or antihistamine alone relieve bronchoconstriction in asthma? Will doctors prescribe one or another or both with beta 2 agonist?

Does anticholinergic or antihistamine alone relieve bronchoconstriction in asthma? Will doctors prescribe one or another or both with beta 2 agonist?

Anticholinergic: Anticholinergic but not the usual doses of antihistamine relieves bronchoconstriction in some people. It may be used as a combination with a beta 2 agonist as in the case of combivent (albuterol and ipratropium). However persistent asthma should be treated with a controller drug such as inhaled steroid and/or a leukotriene blocker. Using just beta agonist alone on a regular basis may actually make your asthma worse. ...Read more
