Beta2-agonist
|
|
Beta2-agonist ß2-agonists are used in the treatment of asthma and chronic obstructive lung disease (COPD) and are used to relax the smooth muscles in the bronchi, which contract during an asthma attack. ß2-agonists are available in short-acting and long-acting formulations for inhalation and as tablets.
RELATED TERMS--------------------------------------
Asthma
Asthma is a chronic, inflammatory lung disease characterized by recurrent breathing problems. People with asthma have acute episodes or when the air passages in their lungs get narrower, and breathing becomes more difficult. Sometimes episodes of asthma are triggered by allergens, although infection, exercise, cold air and other factors are also important triggers.
Chronic
Ongoing or recurring. Chronic medical conditions include diabetes, epilepsy, and chronic fatigue syndrome.
Disease
Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.
Bronchi
The two respiratory tubes branching into the two lungs at the lower end of the trachea. They branch into progressively smaller passageways, the bronchioles, and finally reach the alveoli, the location where gas exchange occurs.
Contract
A written, dated, and signed agreement between two or more involved parties that sets out any arrangements on delegation and distribution of tasks and obligations and, if appropriate, on financial matters. The protocol may serve as the basis of a contract.

Beta adrenergic blocking agents
"A class of drugs, also called beta blockers, that block beta-adrenergic substances such as adrenaline (epinephrine), a key agent in the ""sympathetic"" portion of the autonomic (involuntary) nervous system."
Beta agonist
See: Beta-agonist.
Beta blocker
An antihypertensive medication that limits the activity of epinephrine (a hormone that increases blood pressure).
Beta Blocker
A drug that slows heart rate, lowers blood pressure, controls angina and protects patients with prior heart attacks from future heart attacks.
Beta carotene
"A vitamin that acts as an antioxidant, protecting cells against oxidation damage. Beta carotene is converted by the body to vitamin A. Food sources of beta carotene include vegetables such as carrots, sweet potatoes, spinach and other leafy green vegetables; and fruit such as cantaloupes and apricots. Excessive carotene in the diet can color the skin yellow, a condition called carotenemia. Carotenemia is sometimes seen in infants fed too many mashed carrots and is a reversible condition. Beta carotene supplements have been found not to reduce the risks for cancer or heart disease."
Beta catenin
A protein that is associated with cells that are destined to become hair follicle cells.
Beta Cell
A type of cell in the pancreas in areas called the Islets of Langerhans. Beta cells make and release insulin, a hormone that controls the level of glucose (sugar) in the blood.
Beta cell, pancreatic
A type of cell in the pancreas (the organ of the digestive system located behind the stomach). Within the pancreas, the beta cells are located in areas called the islets of Langerhans. They constitute the predominant type of cell in the islets. The beta cells are important because they make insulin. Degeneration of the beta cells is the main cause of type I (insulin-dependent) diabetes mellitus.
Beta error
"The statistical error (said to be ""of the second kind"" or type II) made in testing when it is concluded that something is negative when it really is positive. Beta error is often referred to as a false negative."
Beta error (statistics)
See Type 2 error.
Beta lipotropin
The biochemical precursor substance from which the body synthesizes endomorphins.
Beta particle
An electron ejected from the nucleus of a decaying atom. Although beta particles can be stopped by a thin sheet of aluminum, they can penetrate the dead skin layer, potentially causing burns. They can pose a serious direct or external radiation threat and can be lethal depending on the amount received. They also pose a serious internal radiation threat if beta-emitting atoms are ingested or inhaled.
Beta protein 1
Abbreviated and better known as BP1. See: BP1.
Beta-2
Beta-2 is a prescription or over-the-counter drug which is (or once was) legal in the United States and possibly in other countries. Active ingredient(s): isoetharine hydrochloride.
Beta-2 agonist
See: Beta-agonist.
Beta-agonist
"A bronchodilator medicine that opens the airways by relaxing the muscles around the airways that may tighten during an asthma attack or in COPD (chronic obstructive pulmonary disease). Beta-agonists can be administered by inhalers or orally. They are called ""agonists"" because they activate the beta-2 receptor on the muscles surrounding the airways. Activation of beta-2 receptors relaxes the muscles surrounding the airways and opens the airways. Dilating airways helps to relieve the symptoms of dyspnea (shortness of breath). Beta-2 agonists have been shown to relieve dyspnea in many asthma and COPD patients. The action of beta-2 agonists starts within minutes after inhalation and lasts for about 4 hours. Because of their quick onset of action, beta-2 agonists are especially helpful for patients who are acutely short of breath but, because of their short duration of action, several doses of beta-agonists are often necessary each day. The side effects of beta-2 agonists include anxiety, tremor, palpitations or fast heart rate, and low blood potassium. "
Beta-blocker
An agent that inhibits the action of beta-adrenergic receptors, which modulate cardiac functions, respiratory functions, and the dilation of blood vessels. Beta-blockers are of value in the treatment of hypertension, cardiac arrhythmias, and migraine. In psychiatry, they have been used in the treatment of aggression and violence, anxiety-related tremors and lithium-induced tremors, neuroleptic-induced akathisia, social phobias, panic states, and alcohol withdrawal.
