Brethaire Asthma Beta Receptor Stimulator
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
Do any beta blockers act on Central Nervous System? Labetalol, Propranalol? What about Alpha-1 blockers?
Yes, most of them: Beta blockers are either water soluble or lipid soluble. The latter cross the blood-brain barrier and act on the CNS (central nervous system). Atenelol and Naldolol are 2 water soluble ones that do not readily cross into the brain. Alpha blockers generally do act on the CNS, and the 2 most common side effects are hypotension and dizziness. ...Read more

Is Cardura (doxazosin) a reasonable second BP drug with Lisinopril when CCBs, diuretics, beta blockers are not well tolerated? Also on B-agonists for asthma.
Yes, it is an option: Cardura (doxazosin) or another alpha blocker type drug is an option when the other classes of drugs mentioned are not well tolerated. Alpha blockers can cause dizziness so they are best taken at night to minimize this effect. The dose needs to be increased slowly. Make sure you are exercising and minimizing salt, alcohol and caffeine as well. ...Read more
The combination help: Pulmicort is an inhaled steroid that reduces inflammation in the lung. Serevent (salmeterol) is a long acting bronchodilator that when used with an inhaled steroid, can help the effectivess of the inhaled steroid. Serevent (salmeterol) used without the inhaled steroid can over 1-2 weeks or more can make asthma worse. Serevent (salmeterol) with asthma should only be used with an inhaled steroid. ...Read more
DoesPrazosin/other alpha blocks act on non-vascular smooth muscle e.g. the throat?If sudafed is alpha stim and contricts nasal,wouldnt it make sense?
Good question: Alphablockers used to treat hypertension seem to be specific for their action on arteriolar musculature as far as I can tell clinically. Sudafed constricts smooth muscle in vessel walls, but can stimulate smooth muscle in the lower urinary tract and cause urinary retention at times. A pharmacologist would be best qualified to answer your question however. ...Read more
Inderal (propranolol) vs tenormin? Inderal (propranolol) fills receptors on heart and lungs. I want to know if filling lungs receptors helps reduce stage fright symptoms. Thanks.
83 yrs f; stable diastolic hf; rate controlled a-fib. Meds: cardizem, coumadin, (warfarin) lasix, inderal, spiriva (mild copd). Would a cardioselective betablocker be better than inderal ?
Theoretically yes: In patients with COPD or asthma , cardioselective beta blockers like atenolol are felt to be superior to Inderal (propranolol) which also has possible harmful effects on the bronchial tree and could produce wheezing(bronchospasm). This may be a concern in someone like you who has copd. Your physician is best to advise you, however especially if you're doing well on inderal (propranolol). ...Read moreSee 1 more doctor answer
Hx: asthma, pts = sm airway, asmanex x1 qhs. New prescription mn txs unit dose albuterol q4 prn. Used 13 of 25 doses in 40 days. Is this reasonable frequency?
No: You should not be using a rescue inhaler as frequently as you are describing. It would appear that you are constantly being exposed to your "trigger(s)" and your controller is not working effectively. Have your physician reevaluate your controller treatment. ...Read moreSee 2 more doctor answers

Only noradrenergic antidepressant works for me, does inderal (propranolol) acts negative on noradrenergic effects of antidepressant ?At vasomotor centers.Regards.
Venlafaxine: It's not the vasomotor centers that are important in antidepressant response; it's the neuron synapses in the brain. Effexor (venlafaxine) inhibits reuptake of both serotonin and ne. Inderal can suppress some of the physical symptoms of anxiety (rapid heart rate, sweaty palms, tremulousness, etc). Some on chronic (not intermittent or "prn") Inderal have had more depression. Not everyone. You should be okay. ...Read more
Yes, to some extent.: Non-selective beta blockers can worsen or help cause an attack. Selective b-blockers are less likely. Those with so caslled, isa effect are less likely. ...Read more

Molecular targeting: These agents are designed to selectively knock out key pathways your tumor may use to grow. Presumably you already had your tumor tested for these different mutations. Ask the doctor offering these options to explain their rationale. These are investigational studies and many of the treatment costs may be covered-ask. ...Read more
