Wikipedia

  1. Quinine

    Quinine is a medication used to treat malaria and babesiosis. This includes the treatment of malaria due to Plasmodium falciparum that is resistant to chloroquine when artesunate is not available. While sometimes used for nocturnal leg cramps, quinine is not recommended for this purpose due to the risk of serious side effects. It can be taken by mouth or intravenously. Malaria resistance to quinine occurs in certain areas of the world. Quinine is also used as an ingredient in tonic water to impart a bitter taste.Common side effects include headache, ringing in the ears, vision issues, and sweating. More severe side effects include deafness, low blood platelets, and an irregular heartbeat. Use can make one more prone to sunburn. While it is unclear if use during pregnancy causes harm to the baby, treating malaria during pregnancy with quinine when appropriate is still recommended. Quinine is an alkaloid, a naturally occurring chemical compound. How it works as a medicine is not entirely clear.Quinine was first isolated in 1820 from the bark of a cinchona tree, which is native to Peru, and its molecular formula was determined by Strecker in 1854. The class of chemical compounds to which it belongs is thus called the cinchona alkaloids. Bark extracts had been used to treat malaria since at least 1632 and it was introduced to Spain as early as 1636 by Jesuit missionaries returning from the New World. It is on the World Health Organization's List of Essential Medicines. Treatment of malaria with quinine marks the first known use of a chemical compound to treat an infectious disease.

  1. quinine

    Quinine is a naturally occurring compound first discovered in the bark of the cinchona tree, which grows in the Andes Mountains. It has been used for centuries to treat malaria due to its ability to kill the malaria parasite in the bloodstream. In addition to its medicinal properties, quinine is also used as a flavor component in beverages such as tonic water and bitter lemon.

  1. Quinine

    Quinine is a natural white crystalline alkaloid having antipyretic, antimalarial, analgesic, and anti-inflammatory properties and a bitter taste. It is a stereoisomer of quinidine which, unlike quinine, is an antiarrhythmic. Quinine contains two major fused-ring systems: the aromatic quinoline and the bicyclic quinuclidine. Though it has been synthesized in the laboratory, quinine occurs naturally in the bark of the cinchona tree. The medicinal properties of the cinchona tree were originally discovered by the Quechua, who are indigenous to Peru and Bolivia; later, the Jesuits were the first to bring cinchona to Europe. Quinine was the first effective treatment for malaria caused by Plasmodium falciparum, appearing in therapeutics in the 17th century. It remained the antimalarial drug of choice until the 1940s, when other drugs such as chloroquine that have fewer unpleasant side effects replaced it. Since then, many effective antimalarials have been introduced, although quinine is still used to treat the disease in certain critical circumstances, such as severe malaria, and in impoverished regions due to its low cost. Quinine is available with a prescription in the United States and over-the-counter, in minute quantities, in tonic water. Quinine is also used to treat lupus and arthritis. Quinine was also frequently prescribed in the US as an off-label treatment for nocturnal leg cramps, but this has become less prevalent due to a Food and Drug Administration statement warning against the practice.

The Nuttall Encyclopedia

  1. Quinine

    an alkaloid obtained from the bark of several species of the cinchona tree and others, and which is employed in medicine specially as a ferbrifuge and a tonic.

U.S. National Library of Medicine

  1. Quinine

    An alkaloid derived from the bark of the cinchona tree. It is used as an antimalarial drug, and is the active ingredient in extracts of the cinchona that have been used for that purpose since before 1633. Quinine is also a mild antipyretic and analgesic and has been used in common cold preparations for that purpose. It was used commonly and as a bitter and flavoring agent, and is still useful for the treatment of babesiosis. Quinine is also useful in some muscular disorders, especially nocturnal leg cramps and myotonia congenita, because of its direct effects on muscle membrane and sodium channels. The mechanisms of its antimalarial effects are not well understood.
