    How does propranolol work


    Propranolol is prescribed to treat a number of different conditions. If you are unsure why you are taking it, speak with your doctor. The most common side-effects are feeling tired, cold hands and feet, disturbed sleep, and stomach upset. Propranolol belongs to the group of medicines known as beta-blockers. It is a medicine which is used to treat several different medical conditions. Propranolol slows down the activity of your heart by stopping messages sent by some nerves to your heart. It does this by blocking tiny areas (called beta-adrenergic receptors) where the messages are received by your heart. As a result, your heart beats more slowly and with less force. Beta blockers can be helpful in the treatment of the physical symptoms of anxiety, especially social anxiety. Physicians prescribe them to control rapid heartbeat, shaking, trembling, and blushing in anxious situations for several hours. Often social anxiety symptoms are so strong that beta blockers, while helpful, cannot reduce enough of the symptoms to provide relief. Because they can lower blood pressure and slow heart rate, people diagnosed with low blood pressure or heart conditions may not be able to take them. May reduce some peripheral symptoms of anxiety, such as tachycardia and sweating, and general tension, can help control symptoms of stage fright and public-speaking fears, has few side effects. Taken occasionally, propranolol has almost no side effects. Atenolol is longer acting than propranolol and generally has fewer side effects. If taken daily, abrupt withdrawal can cause very high blood pressure. If there is no response, increase to two 50 mg tablets, taken together or divided. Not recommended for patients with asthma or any other respiratory illness that causes wheezing, or for patients with diabetes. Some people may feel a little light-headed, sleepy, short-term memory loss, unusually slow pulse, lethargy, insomnia, diarrhea, cold hands and feet, numbness and/or tingling of fingers and toes. It has less of a tendency to produce wheezing than other beta blockers. Use alcohol with caution, since alcohol can increase the sedative effect and exaggerate this drug's ability to lower blood pressure. After two weeks of 100 mg the patient should notice a marked decrease in the racing heart, trembling, blushing, and/or sweating in social situations.

    A startup wants to create a platform for people anxious about public speaking to get prescriptions for a cardiac drug that can calm racing hearts. 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. Propranolol is a beta-adrenergic blocking agent.

    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). Propranolol, which treats high blood pressure, irregular heart rhythms, chest pain, and other heart symptoms, is also approved by the U. Food and Drug Administration (FDA) for preventing migraine attacks. Propranolol falls into the beta-blocker class of medications. Beta blockers reduce the frequency of migraine attacks in 60 to 80 percent of people. It is not clear, however, if propranolol affects active migraine, so it should not be taken to stop migraine attacks already in progress. Propranolol is available in multiple formulations, including tablets, liquid, and a long-acting time-release capsule. Propranolol is the active ingredient in Inderal LA, Inderal XL, and Inno Pran XL. Propranolol works by blocking certain receptors, known as beta receptors, in blood vessels.

    There are three doses of Viagra available, the highest of which is 100mg. Because it contains such a large amount of the active ingredient sildenafil, it is only issued in certain cases. If after starting on the middle dose, the patient finds that the medication does not quite produce an erection firm or sustainable enough for sexual intercourse, then a doctor may recommend raising the dose to Viagra 100mg. Users should be aware that taking the pill alongside alcohol or a large meal may reduce its effects. When taking a lower dose, it is advisable to eliminate these function-inhibiting factors before approaching your doctor because the treatment hasn’t worked sufficiently. As with any medication, a doctor will always prescribe the lowest dose possible. The highest dose of Viagra is only given where appropriate to those patients who are healthy and are absolutely not at risk of experiencing side effects.
