A sympathomimetic drug used in treating asthma.
A drug that relieves asthma and blocked noses by causing the air passages to widen.
Ephedrine is a stimulant that can be obtained from the herb ma huang also known as Ephedra sinica. The Food and Drug Administration (FDA) has prohibited the sale of dietary supplements containing ephedrine alkaloids and has recommended that Americans discontinue its use. Those supplements were previously marketed for a variety of reasons, but especially as a way to increase energy expenditure and weight loss. As reviewed by Williams, while several studies have not detected positive effects on athletic performance, a few have, particularly when ephedrine was combined with caffeine. Since the FDA has concluded that ephedrine-containing supplements pose an unreasonable health risk, particularly with regard to the heart, ephedrine can not be recommended as an ergogenic aid.
Bronchodilator; drug that widens the air passages of the lungs and is used to treat asthma, bronchitis, and other conditions. Adverse effects include headache, nervousness, and insomnia.
A popular nonprescription decongestant that acts by releasing epinephrine from nerve cells to relieve nasal congestion. Derived from Ephedra, the scientific name for an Asian plant, the decongestant acts as a stimulant and is often abused for that reason. Ephedrine is also used in some weight-loss products because of its effect as a stimulant.
A drug that causes constriction of blood vessels and widening of the bronchial passages. It is used mainly in the treatment of asthma and other allergic conditions and chronic bronchitis. It is administered by mouth or by inhalation and may cause nausea and vomiting, insomnia, headache, and nervousness.
An alkaloid derived from a species of Ephedra or prepared synthetically. A bronchodilator, it was once widely used to treat asthma, but has now been superseded by the much safer (and more effective) selective beta-2-adrenoceptor stimulants. Ephedrine is a constituent of several decongestant cold and cough remedies available to the general public.
A synthetic sympathomimetic alkaloid originally obtained from species of Ephedra; first isolated in 1887. In ancient Chinese medicine it was used as a diaphoretic and antipyretic. Its action is similar to that of epinephrine. Its effects, although less powerful, are more prolonged, and it exerts action when given orally, whereas epinephrine is effective only by injection. Ephedrine dilates the bronchial muscles, contracts the nasal mucosa, and raises the blood pressure. It is used chiefly for its bronchodilating effect in asthma, and for its constricting effect on the nasal mucosa in hay fever.
A substance extracted from an Asian herb called ephedra and used in an array of products sold as weight-loss aids, asthma products, and energy boosters. Also called Ma-huang, Mormon tea, or Brigham tea. Effects can cause blood vessel constriction, a sudden rise in blood pressure, and body heat.
An agent with sympathomimetic properties, frequently employed as a stimulant, anorectic, nootropic, and decongestant.
Ephedrine is a medication that imitates the actions of the neurotransmitter noradrenaline (norepinephrine). It is commonly prescribed as a decongestant to alleviate nasal congestion. Additionally, it can be utilized in certain instances of low blood pressure caused by drug effects or medical conditions.
A medication with various applications, including asthma relief, alleviating breathlessness in chronic bronchitis and emphysema, interrupting migraine headaches, addressing bed-wetting in children, treating specific muscle conditions, serving as a nasal spray for hay fever, and managing narcolepsy—a condition causing sudden, irresistible bouts of sleep. Originally derived from a plant in China, ephedrine is now synthetically produced, making it more cost-effective.
