    Propranolol review


    According to the American Academy of Neurology, propranolol (a high blood pressure medication) is considered a "level A" drug, which means it is effective and should be offered by headache specialists to their patients for migraine prevention. While the "how" behind propranolol's role in migraine prevention is largely unclear, experts speculate that as a beta-blocker, propranolol blocks adrenaline (your flight or fight hormone) from binding to blood vessels surrounding the brain. In essence, this relaxes the blood vessels, theoretically thwarting a migraine attack. Keep in mind, though, research suggests that propranolol only works for some people—it's not a magic cure and thus, requires a trial and error process, which can be tedious, but worthwhile for some. Propranolol, known by the brand names Inderal and Inno Pran in the United States, is approved by the Food and Drug Administration for preventing migraines and treating high blood pressure and essential tremor, among other conditions. Propranolol is available as an immediate-release tablet or an extended release capsule. The immediate release tablet should be taken on an empty stomach while the extended release capsule can be taken with or without food (but should be done consistently). sildenafil 20 The pharmacokinetics of propranolol vary according to the route and duration of administration. administration, the decline in drug concentrations is biphasic and the drug is cleared very efficiently by the liver, so that its elimination is dependent largely on liver blood flow. Although the drug is some 90-95% bound to plasma, hepatic removal is so avid that both bound and free forms are extracted. Consequently, hepatic elimination is unaffected by drug binding in blood, In contrast, the distribution of drug into the tissues is reduced by plasma binding, so that drug half-life (T 1/2), which varies from 11/2-3 hours among individuals is more prolonged in people with relatively low plasma binding. administration the beta-blocking effects of propranolol are related to its plasma concentrations according to the receptor theory. In addition individual differences in the response due to a given total concentration are largely due to variations in plasma binding, the drug's effects being a function of free (unbound) drug in plasma water. After the administration of single oral doses, hepatic extraction remains high and much of the dose is eliminated from hepatic portal blood during transfer from the gut, so that little drug reaches the systemic circulation. In addition, significant amounts of an active metabolite, 4-OH propranolol, are produced so that 2 hours after dosing, propranolol appears more potent that its plasma levels would suggest. With continued administration, the avid removal process becomes saturated, extraction ratio falls and propranolol accumulates some 2-fold.

    Infantile haemangiomas (IH) are benign vascular tumours characterised by their very rapid growth. Although usually innocuous, periocular IH can cause serious visual loss through induction of strabismic, deprivational or anisometropic astigmatism. Common treatment modalities for these IH include intralesional and systemic oral steroids; however, both treatments are associated with potentially severe side effects. A report was published recently demonstrating the impressive effect of propranolol in the treatment of IH. This exciting finding has provoked a paradigm shift in the management of this condition. So far little has been reported in the specific ophthalmologic literature, although case reports are emerging. This review gives an overview of the recent findings and includes the authors' experience with 10 patients treated with propranol. 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).
