• epinephrine
  • Beta adrenergic receptors are involved in the epinephrine- and norepinephrine-induced activation of adenylate cyclase through the action of the G proteins of the type Gs. (wikipedia.org)

  • carvedilol
  • And some of the drugs exert additional properties independent of beta-receptors, for example, carvedilol causes vasodilation via inhibition of sympathetic alpha-receptors, nebivolol causes NO-derived vasodilation, sotalol shows antiarrhythmic class III effects, and propranolol inhibits the conversion of thyroxine to triiodothyronine. (escardio.org)
  • Accordingly, the 2007 Guidelines for the management of arterial hypertension of the European Society of Hypertension and the European Society of, Cardiology4,5 emphasise that "this may not apply, however, to vasodilator beta-blockers, such as carvedilol and nebivolol, which have less or no metabolic action, as well as a reduced incidence of new onset diabetes compared with classical beta-blockers.

  • patients
  • Patients with BP in this range who are asymptomatic should be referred for repeat BP measurement within 1 to 2 weeks at the primary care provider's office. (oncologynurseadvisor.com)
  • Many heart failure patients are unable to reach target beta blocker doses. (clinicaltrials.gov)
  • Beta blockers have been proven to have benefit in heart failure (HF) patients with regard to morbidity and mortality. (clinicaltrials.gov)
  • Furthermore, patients with heart rates of 64 bpm or less are rarely begun on beta-blocker therapy. (clinicaltrials.gov)
  • It is not known whether these patients should be given a pacemaker in order to then safely initiate beta-blocker therapy. (clinicaltrials.gov)
  • It is hypothesized that CRT therapy allows for increased Beta -blocker dose (or initiation of beta-blocker in patients previously intolerant) with improved NYHA, ejection fraction, and remodeling effects. (clinicaltrials.gov)
  • LVESVI change in patients with CRT/ increased dose of beta-blockers vs CRT and no change in beta-blocker dose. (clinicaltrials.gov)
  • Patients were randomized into two groups according to whether they did not (group 1, n = 20) or did have (group 2, n = 20) pretreatment with an alpha 1 -adrenergic receptor blocker (oral doxazosin, 2 mg). (onlinejacc.org)
  • 0.001), as compared with baseline values, in group 1 patients. (onlinejacc.org)
  • The occurrence of transient myocardial ischemia in patients with coronary artery disease during stress is a common problem and has been thought to reflect adrenergic stimulation, with resultant increases in cardiac oxygen consumption. (onlinejacc.org)
  • By some estimates, 25 to 50 percent of hospital deaths of patients with unmanaged or unknown pheochromocytoma occur during induction of anesthesia or during operative procedures for other conditions [ 1 ]. (uptodate.com)
  • adrenoceptors
  • The present study shows, for the first time, that urinary bladder distention caused vasoconstriction of coronary conduit and resistance vessels involved mechanisms related to alpha 1 adrenoceptors. (onlinejacc.org)
  • metoprolol
  • other beta-blockers of the 2nd generation, especiallly metoprolol and bisoprolol, still remain indicated particularly in the treatment of coronary artery disease, tachyarrhythmias and heart failure since they never were shown to share these disadvantages with atenolol. (escardio.org)
  • physiological
  • Besides, a pupillary diameter difference less than 1 mm is often a physiological condition occurring in about 20% of the population. (medsci.org)
  • Heart Failure
  • Accordingly, impaired myocardial perfusion secondary to microvascular dysfunction has been postulated to play a major role in the progression of heart failure despite standard therapy for heart failure (1). (clinicaltrials.gov)
  • Therefore
  • Therefore, beta-blockers should be recognised as individual substances with their own qualities and used according to the individual features, needs and demands of every single patient. (escardio.org)
  • PTSD
  • Furthermore, α-blockers can occasionally be used to treat anxiety and panic disorders, such as Post Traumatic Stress Disorder (PTSD) induced nightmares. (wikipedia.org)
  • doses
  • Neurologic: Headache (2%), Dizziness (11%) Gastrointestinal: Nausea (6%), Dyspepsia (3%) Cholinergic: Nasal congestion (3%), Ejaculation failure (2%) Respiratory: Dyspnea (2%) Other: Fatigue (5%), Vertigo (2%), Orthostatic hypotension Low blood pressure with standing is more severe and more common with IV formulation (58% vs 1%) and is often the reason larger doses of the oral formulation cannot be used.
