Levoamphetamine (also levamfetamine (INN), (R)-amphetamine or (−)-amphetamine) is a central nervous system (CNS) stimulant known to increase wakefulness and concentration in association with decreased appetite and fatigue. 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 the levorotatory stereoisomer of the amphetamine molecule.

Chemistry

Levoamphetamine is the levorotary stereoisomer of the amphetamine molecule. Racemic amphetamine contains two optical isomers, dextroamphetamine and levoamphetamine.[4]

Formulations

Racemic amphetamine

The first patented amphetamine brand, Benzedrine, was a racemic (i.e., equal parts) mixture of the freebases 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.[2] It was later realized that the amphetamine enantiomers could treat obesity, narcolepsy, and ADHD.[2][3] The Benzedrine brand is no longer marketed;[5] however, racemic amphetamine sulfate is still prescribed under other brand names (e.g., Evekeo) and as their generic equivalents.[3][6]

Adderall

Adderall (nonproprietary name: dextroamphetamine sulfate, dextroamphetamine saccharate, amphetamine sulfate and amphetamine aspartate)[7] is an amphetamine pharmaceutical that contains 25% levoamphetamine salts and 75% dextroamphetamine salts.[4]
