<p><b>New page</b></p><div>[[File:L-amphetamine.svg|thumb|L-amphetamine.svg]] '''Levoamphetamine''' is a [[central nervous system]] (CNS) stimulant and one of the two [[enantiomers]] of the compound [[amphetamine]]. The other enantiomer is [[dextroamphetamine]]. Levoamphetamine is the levorotatory stereoisomer of amphetamine, meaning it rotates plane-polarized light to the left.<br />
<br />
==Chemical Structure and Properties==<br />
Levoamphetamine has the chemical formula C9H13N and a molecular weight of 135.21 g/mol. It is a member of the [[phenethylamine]] class and is structurally similar to other stimulants such as [[methamphetamine]] and [[ephedrine]].<br />
<br />
==Pharmacology==<br />
Levoamphetamine acts primarily by increasing the release of [[neurotransmitters]] such as [[dopamine]], [[norepinephrine]], and [[serotonin]] in the brain. This leads to increased arousal, concentration, and energy levels. It is less potent than dextroamphetamine in terms of its CNS stimulant effects but has a more pronounced effect on the peripheral nervous system.<br />
<br />
==Medical Uses==<br />
Levoamphetamine is used in the treatment of [[attention deficit hyperactivity disorder]] (ADHD) and [[narcolepsy]]. It is often found in combination with dextroamphetamine in medications such as [[Adderall]], which is used to treat these conditions.<br />
<br />
==Side Effects==<br />
Common side effects of levoamphetamine include [[insomnia]], [[dry mouth]], [[loss of appetite]], and [[increased heart rate]]. More severe side effects can include [[hypertension]], [[tachycardia]], and [[psychosis]].<br />
<br />
==Legal Status==<br />
Levoamphetamine is classified as a [[Schedule II controlled substance]] in the United States, indicating it has a high potential for abuse and dependence but also has accepted medical uses.<br />
<br />
==History==<br />
Levoamphetamine was first synthesized in the late 19th century and has been used medically since the 1930s. It gained popularity during [[World War II]] for its stimulant effects, which were used to keep soldiers alert.<br />
