extended-release<unk>  A mixture of 20 mg and 10 mg<unk>  tablets<unk> <unk>  is used for treating various conditions, including: Cardiovascular * Hypertension * Angina pectoris (with the exception of variant angina) * Myocardial infarction * Tachycardia (and other sympathetic nervous system symptoms, such as muscle tremor) associated with various conditions, including anxiety, panic, hyperthyroidism, and lithium therapy * Portal hypertension, to lower portal vein<unk> essure *<unk> evention of esophageal variceal bleeding and ascites * Anxiety * Hypertrophic cardiomyopathy While once a first-line treatment for hypertension, the role for<unk>  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<unk>  blockers at usual doses carry an unacceptable risk of<unk> ovoking type 2 diabetes.<unk>  is not recommended for the treatment of high blood<unk> essure by the Eighth Joint National Committee (JNC 8) because a higher rate of the<unk> imary composite outcome of cardiovascular death, myocardial infarction, or stroke compared to an angiotensin receptor blocker was noted in one study. Psychiatric<unk>  is occasionally used to treat performance anxiety, although evidence to support its use in any anxiety disorders is poor. Its benefits appear similar to benzodiazepines in panic disorder with potentially fewer side effects such as addiction. Some experimentation has been conducted in other psychiatric areas: * Post-traumatic stress disorder (PTSD) and specific phobias (see subsection below) * Aggressive behavior of patients with brain injuries * Treating the excessive drinking of fluids in psychogenic polydipsia PTSD and phobias<unk>  is being investigated as a potential treatment for PTSD.<unk>  works to inhibit the actions of norepinephrine, a neurotransmitter that enhances memory consolidation. In one small study individuals given<unk>  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,<unk>  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<unk> -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<unk>  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." Other uses * Essential tremor. Evidence for use for akathisia however is insufficient * Migraine and cluster headache<unk> evention and in<unk> imary exertional headache * Hyperhidrosis (excessive sweating) *<unk> oliferating infantile hemangioma * Glaucoma * Thyrotoxicosis by deiodinase inhibition<unk>  may be used to treat severe infantile hemangiomas (IHs). This treatment shows<unk> omise as being superior to corticosteroids when treating IHs. Extensive clinical case evidence and a small controlled trial support its efficacy.
