    Propranolol essential tremor


    When Essential Tremor significantly interferes with daily activities, long-term drug treatment is needed. Drugs most commonly used to treat the condition include beta-blockers (propranolol) and an epilepsy drug called primidone (Mysoline). Topiramate (Topamax), another drug used to treat epilepsy and migraine, helps some people. With the use of medication, people with essential tremor may see improvement in their ability to control their tremor and improvement in activities such as drinking from a cup or using food utensils. More specialized motor functions, such as being able to thread a needle, may still be too difficult. However, for most people, essential tremor is not disabling. Your health care provider will determine which treatment is best for you based on your medical history. Your doctor might order a magnetic resonance imaging (MRI) scan or a computerized axial tomography (CAT) scan if there is a suspicion of some other cause of tremor. Here are some questions you may be asked: A brain scan is not required to diagnose ET. During your physical exam, your doctor will be gathering as much information as possible about your tremor. Doctors who are trained to evaluate tremor can accurately diagnose ET on the basis of the symptoms and a neurological examination. Before making a diagnosis of ET, your doctor may want to investigate other possible causes of tremor such as thyroid disease, excessive caffeine ingestion or medication side effects. Not everyone who inherits a gene develops symptoms, and some people have ET and do not have a family history of tremor, possibly suggesting other causes. The course of ET is variable and may be progressive over many decades. Can a diagnosis of ET be made from looking at a brain scan? Researchers have already located two genes that predispose to ET and are currently trying to locate others. No one group of people is more likely to develop ET. No one can predict how much your tremor will worsen with time. This means that each child of a parent with ET has approximately a 50% chance of inheriting a gene that causes ET. Though ET may first appear at any age between childhood and old age, onset is rare before the age of ten. ET is found in all races and in all parts of the world.

    Age at onset of essential tremor has two peaks, early in life and in older age. Treatment of essential tremor usually begins with primidone or propranolol. We conclude that propranolol and primidone are effective long-term treatment for some patients with essential tremor. Acute adverse reactions with primidone. Propranolol taken once daily at doses of 160, 240 and 320mg, was shown to be as effective as. in essential tremor which have implications for future studies.

    Beta-adrenergic blockers (principally propranolol) and primidone are the first-line treatment for essential tremor. Each provides good benefit in 50-70% of cases and neither has been demonstrated to be unequivocally superior to the other. Adverse effects are more prominent early in treatment with primidone but are more prominent later in treatment with propranolol. Starting with propranolol is preferable in younger individuals, and primidone is started first in older patients. Patients are usually started on one of these medications. The drug is introduced at a low dose that is increased slowly until complete response, tolerance, or usual maximum dose is attained. If some benefit is achieved but is incomplete, the other medication may be introduced and increased in an effort to achieve maximum benefit. When essential tremor (ET) is early and mild, symptoms generally don’t interfere with daily tasks. If symptoms worsen, medication may be prescribed to reduce the speed (frequency) and amplitude (size) of motion. One type of drug used to control ET is called a beta blocker. As the name suggests, the action of the drug blocks the effect of adrenaline on specific receptors. One type is used after a heart attack to reduce risk of another attack. Others are used to regulate abnormal heart rhythm (arrhythmia) or lower blood pressure. A type that opens up blood vessels may help lessen migraine headaches. One particular beta blocker, propranolol, is used to control ET and is usually the first choice for younger patients.

    Traveler’s diarrhea (dysentery, Montezuma’s revenge) is usually a self-limiting episode of diarrhea that results from eating food or water that is contaminated with bacteria or viruses. Traveler’s diarrhea is most common in developing countries that lack resources to ensure proper waste disposal and water treatment. Onset is often sudden and usually lasts 3-5 days or longer. The severity of diarrhea can vary and can be accompanied by cramps, bloating, nausea, vomiting and /or fever. In severe cases, life-threatening dehydration can occur, especially in babies, young children and the elderly. It is estimated that up to 40% of travelers experience some form of traveler’s diarrhea. The best practice is to avoid eating and drinking food and water that are contaminated with human waste (stool, feces). This can be accomplished by: How do I treat traveler’s diarrhea?
