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. Hemangeol (propranolol oral liquid 4.28 milligrams) is given to infants who are at least 5 weeks old to treat a genetic condition called infantile hemangiomas. Hemangiomas are caused by blood vessels grouping together in an abnormal way. These blood vessels form benign (non-cancerous) growths that can develop into ulcers or red marks on the skin. Hemangiomas can also cause more serious complications inside the body (in the liver, brain, or digestive system). The Repurposing Drugs in Oncology (Re DO) project, an international collaboration between the Anticancer Fund, Belgium, and US based Global Cures, says that existing and widely-used non-cancer drugs may represent a relatively untapped source of novel therapies for cancer. Historically, pharmaceutical companies devote little time to "repurposing" existing drugs. The Re DO project hopes to change that, raising awareness by publishing a series of articles in ecancer to share evidence for using these therapies in cancer medicine. Propranolol is the latest in a series of drugs that could offer cheap, safe and effective solutions to cancer. It's available globally in generic form and is on the WHO List of Essential Medicines -- particularly in angiosarcoma, a rare form of heart cancer. "The evidence to date in angiosarcoma is especially compelling," says study author Pan Pantziarka, Ph D, of the Anticancer Fund, Belgium. "Here is a rare disease with high unmet needs that is unlikely to attract investment from the commercial drug development sector.
The actor Laurence Olivier described it as shattering. The pianist Vladimir Horowitz found it so disabling that he didn't perform for 12 years. dread speaking in front of an audience, a 2001Gallup poll found. Stage fright—also known as performance anxiety—strikes all kinds of people, including surgeons, athletes, students, pilots, and even public speakers. While many people feel apprehensive in such situations, those with performance anxiety suffer from an intense fear of humiliation, embarrassment, or scrutiny by others. A stressful event such as a music recital or speech sets off their body's "fight or flight" response, triggering symptoms such as heavy sweating, heart palpitations, trembling, blushing, dry mouth, gastrointestinal distress, and hyperventilation. The anxiety drives some to abandon successful careers or self-medicate with alcohol or drugs. But other people sometimes use beta-blockers, most commonly propranolol (Inderal and generic), as well as pindolol (Visken and generic); acebutolol (Sectral and generic); and atenolol (Tenormin and generic). The Food and Drug Administration approved beta-blockers for the treatment of high blood pressure, heart conditions, and certain types of tremors, and for the prevention of migraines and repeat heart attacks. This lesson defines a cardiovascular medication known as propranolol. You'll learn how it works and, as a result, what it's used for. You'll also learn why propranolol might be effective in treating, of all things, anxiety. As you just learned, if epinephrine stimulates the beta receptors, then we can expect a faster heart rate and increased blood pressure. Have you ever been really stressed out at the doctor's office? It's because a hormone called epinephrine (adrenaline) stimulates receptors, called beta receptors. Thus, by blocking beta receptors, propranolol helps to reverse these changes or prevent them in the first place. If you have, do you recall what your blood pressure or heart rate was, roughly? Their stimulation increases the rate at which your heart beats and it increases your blood pressure as well. More specifically, it's stimulation of the beta-1 receptors that leads to a faster heart rate. Keep this in mind as we go over propranolol, namely its uses (especially for anxiety). So, the blockage of these guys with propranolol decreases heart rate. Stimulation of beta-1 receptors also causes the release of a compound called renin, whose actions cause a cascade of events to occur, ones that end up increasing a person's blood pressure.
WHO among us hasn’t wanted to let go of anxiety or forget about fear? Phobias, panic attacks and disorders like post-traumatic stress are extremely common: 29 percent of American adults will suffer from anxiety at some point in their lives. Sitting at the heart of much anxiety and fear is emotional memory — all the associations that you have between various stimuli and experiences and your emotional response to them. Whether it’s the fear of being embarrassed while talking to strangers (typical of social phobia) or the dread of being attacked while walking down a dark street after you’ve been assaulted (a symptom of PTSD), you have learned that a previously harmless situation predicts something dangerous. It has been an article of faith in neuroscience and psychiatry that, once formed, emotional memories are permanent. The best we could do was to get you to tolerate them, but we could never really rid you of your initial fear. The current standard of treatment for such phobias revolves around exposure therapy. This involves repeatedly presenting the feared object or frightening memory in a safe setting, so that the patient acquires a new safe memory that resides in his brain alongside the bad memory. As long as the new memory has the upper hand, his fear is suppressed.
