    Propranolol heart failure


    While once a first-line treatment for hypertension, the role for beta blockers was downgraded in June 2006 in the United Kingdom to fourth-line, as they do not perform as well as other drugs, particularly in the elderly, and evidence is increasing that the most frequently used beta blockers at usual doses carry an unacceptable risk of provoking type 2 diabetes. Propranolol is not recommended for the treatment of hypertension by the Eighth Joint National Committee (JNC 8) because a higher rate of the primary composite outcome of cardiovascular death, myocardial infarction, or stroke compared to an angiotensin receptor blocker was noted in one study. Propranolol works to inhibit the actions of norepinephrine, a neurotransmitter that enhances memory consolidation. In one small study individuals given propranolol immediately after trauma experienced fewer stress-related symptoms and lower rates of PTSD than respective control groups who did not receive the drug. Due to the fact that memories and their emotional content are reconsolidated in the hours after they are recalled/re-experienced, propranolol can also diminish the emotional impact of already formed memories; for this reason, it is also being studied in the treatment of specific phobias, such as arachnophobia, dental fear, and social phobia. Ethical and legal questions have been raised surrounding the use of propranolol-based medications for use as a "memory damper", including: altering memory-recalled evidence during an investigation, modifying behavioral response to past (albeit traumatic) experiences, the regulation of these drugs, and others. However, Hall and Carter have argued that many such objections are "based on wildly exaggerated and unrealistic scenarios that ignore the limited action of propranolol in affecting memory, underplay the debilitating impact that PTSD has on those who suffer from it, and fail to acknowledge the extent to which drugs like alcohol are already used for this purpose." Propranolol may be used to treat severe infantile hemangiomas (IHs). However, it had several methodologic problems: it was a composite of 4 smaller studies that used exercise tolerance as the primary endpoint; median duration of data collection on subjects was only 6 months; it included many minimally symptomatic patients; the actual number of deaths was small (producing a wide confidence interval); and subjects who did not survive the run-in phase were excluded from analysis. The effect of carvedilol on morbidity and mortality in patients with chronic heart failure. The US Carvedilol trial demonstrated a larger reduction in mortality than that seen in other beta-blocker trials. We found no meta-analysis that pooled data on individual drugs for comparison purposes. This suggests there may be differences in effectiveness among beta-blockers in reducing mortality in heart failure, and that it would be unwise to assume that protection is a class effect. The Carvedilol Prospective Randomized Cumulative Survival (BEST) demonstrated no effect with bucindolol. Effect of carvedilol on survival in severe chronic heart failure. Effect of metoprolol CR/XL in chronic heart failure: Metotprolol CR/XL Randomized Intervention Trial in Congestive Heart Failure (MERIT-HF). The Cardiac Insufficiency Bisoprolol Study II (CIBIS-II): a randomised trial. A trial of the beta-blocker bucindolol in patients with advanced chronic heart failure. Differential effects of beta-blockers in patients with heart failure: A prospective, randomized, double-blind comparison of the long-term effects of metoprolol versus carvedilol. In all trials, the majority of subjects were taking diuretics and either an ACE inhibitor or angiotensin receptor blocker. Influence of beta-blockers on mortality in chronic heart failure. Metra M, Giubbini Raffaele, Nodari E, Boldi E, Modena MG, Dei Cas L. Rationale and design of the carvedilol or metoprolol European trail in patients with chronic heart failure: COMET. The Table shows the 5 largest trials of beta-blockers in systolic dysfunction, including patients with both ischemic and nonischemic heart disease.

    Indian Heart J. 2010 Mar-Apr;622101-10. Beta-blockers and heart failure. Lipophilic BB like propranolol and metoprolol appear in high concentrations in. Beta-blockers were traditionally thought to be contraindicated in heart failure due to their. 'First-generation' compounds, such as propranolol, are non-selective. Do not stop taking propranolol without talking to your doctor first. If propranolol is stopped suddenly, it may cause chest pain or heart attack in.

    Propranolol is used to treat high blood pressure, irregular heart rhythms, pheochromocytoma (tumor on a small gland near the kidneys), certain types of tremor, and hypertrophic subaortic stenosis (a heart muscle disease). It is also used to prevent angina (chest pain), migraine headaches, and to improve survival after a heart attack. Propranolol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure. High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. You should not use this medication if you are allergic to propranolol, if you have asthma, a slow heart rate, or a serious heart condition such as "sick sinus syndrome" or "AV block" (unless you have a pacemaker). Propranolol is only part of a complete program of treatment for hypertension that may also include diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely if you are being treated for hypertension. If you are being treated for high blood pressure, keep using this medication even if you feel well. You may need to use blood pressure medication for the rest of your life. Beta-blockers affect the heart and circulation (blood flow through arteries and veins). Propranolol is used to treat tremors, angina (chest pain), hypertension (high blood pressure), heart rhythm disorders, and other heart or circulatory conditions. It is also used to treat or prevent heart attack, and to reduce the severity and frequency of migraine headaches. Propranolol may also be used for purposes not listed in this medication guide.

    Azithromycin (Zithromax), a widely prescribed antibiotic, is used to treat a myriad of infections. Most often, it is prescribed for upper respiratory infection, community acquired pneumonia, otitis media, pertusis and bacterial sinusitis. In general terms, azithromycin will combat most respiratory tract or soft tissue infections. Azithromycin solution is loved by many parents because it is well received by children, has a small dosing quantity and short length of therapy Azithromycin belongs to a group of antibiotics called macrolides. Other macrolides include erythromycin (Ery-Tab), clindamycin (Cleocin), clarithromycin (Klaricid) and telithromycin (Ketek). Macrolides work by preventing bacteria from multiplying and producing proteins that are essential for their growth. The bacteria eventually die or are killed by the immune system. Just a note here about antibiotics and the difference between bacteriostatic versus bactericidal antibiotics. HIGHLIGHTS OF PRESCRIBING INFORMATION Days 2 through 5.
