They were also able to apply the process to produce many other chemicals used in medicine and agriculture for a fraction of the usual cost. The UCLA researchers devised an inexpensive way to produce this drug molecule from a chemical costing just $3 per gram. One chemical used in some anti-cancer drugs, for example, costs pharmaceutical companies $3,200 per gram - 50 times more than a gram of gold. Thanks to pathbreaking research by UCLA chemists, led by organic chemistry professor Ohyun Kwon, the price of drug treatments for cancer and other serious illnesses may soon plummet. Traditional metal catalysis uses expensive metals such as platinum, silver, gold and palladium, but the researchers used oxygen and copper - an abundant base metal.ĭrugs to treat cancer are often very expensive to produce, resulting in high costs for the patients who need them.Using oxygen as a reagent and copper as a catalyst to break organic molecules ’ carbon-carbon bonds and convert them into amines, which are widely used in pharmaceuticals.UCLA researchers have devised a way to produce chemicals used in medicine and agriculture for a fraction of the usual cost.^ 'Adzenys ER- amphetamine suspension, extended release'.Adzenys XR-ODT (amphetamine extended-release orally disintegrating tablet) contains a 3 to 1 ratio of d- to l-amphetamine, a central nervous system stimulant. ^ 'Adzenys XR-ODT- amphetamine tablet, orally disintegrating'.^ 'Dyanavel XR Prescribing Information'.^ 'Evekeo ODT- amphetamine sulfate tablet, orally disintegrating'.^ a b 'Adderall- dextroamphetamine saccharate, amphetamine aspartate, dextroamphetamine sulfate, and amphetamine sulfate tablet'.^ a b 'Adderall XR- dextroamphetamine sulfate, dextroamphetamine saccharate, amphetamine sulfate and amphetamine aspartate capsule, extended release'.International Union of Basic and Clinical Pharmacology. ^ a b c d e 'Evekeo- amphetamine sulfate tablet'.'Amphetamine, past and present – a pharmacological and clinical perspective'. ^ a b c Heal DJ, Smith SL, Gosden J, Nutt DJ (June 2013).United States National Library of Medicine – National Center for Biotechnology Information. Įnantiopure levoamphetamine succinate was sold in Hungary between 19 under the brand name Cydril. Adzenys XR, an orally dissolving tablet came to market in 2016 and contains 25% levoamphetamine. Dyanavel XR, a liquid suspension form became available in 2015, and contains about 24% levoamphetamine. Products using amphetamine base are now marketed. The orally disintegrating tablets are approved for the treatment of attention deficit hyperactivity disorder (ADHD) in children and adolescents aged six to 17 years of age. It is approved for the treatment of narcolepsy, ADHD, and exogenous obesity. Evekeo Įvekeo is an FDA-approved medication that contains racemic amphetamine sulfate (i.e., 50% levoamphetamine sulfate and 50% dextroamphetamine sulfate). This result is a 76% dextroamphetamine to 24% levoamphetamine, or 3⁄ 4 to 1⁄ 4 ratio. Adderall Īdderall is a 3.1:1 mixture of dextro- to levo- amphetamine base equivalent pharmaceutical that contains equal amounts (by weight) of four salts: dextroamphetamine sulfate, amphetamine sulfate, dextroamphetamine saccharate and amphetamine (D,L)-aspartate monohydrate. However, in 2012, racemic amphetamine sulfate was reintroduced as the Evekeo brandname. Because of the greater central nervous system effect of the dextrorotatory enantiomer (i.e., dextroamphetamine), sold as Dexedrine, prescription of the Benzedrine brand fell and was eventually discontinued. It was later realized that the amphetamine enantiomers could treat obesity, narcolepsy, and ADHD.

The first patented amphetamine brand, Benzedrine, was a racemic (i.e., equal parts) mixture of the free bases or sulfate salts of both amphetamine enantiomers (levoamphetamine and dextroamphetamine) that was introduced in the United States in 1934 as an inhaler for treating nasal congestion.

Racemic amphetamine contains two optical isomers, dextroamphetamine, and levoamphetamine. Levoamphetamine is the levorotatory stereoisomer of the amphetamine molecule.

While pharmaceutical formulations containing enantiopure levoamphetamine are no longer manufactured, levomethamphetamine (levmetamfetamine) is still marketed and sold over-the-counter as a nasal decongestant.

Pharmaceuticals that contain levoamphetamine are currently indicated and prescribed for the treatment of attention deficit hyperactivity disorder (ADHD), obesity, and narcolepsy in some countries. Levoamphetamine is a central nervous system (CNS) stimulant known to increase wakefulness and concentration in association with decreased appetite and fatigue.
