Adderall
Adderall is the brand name of a fixed-dose combination medication used for the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy. It is also used as an athletic performance enhancer, cognitive enhancer, appetite suppressant, and recreationally as a euphoriant. Such uses are illegal in many countries. It is a central nervous system (CNS) stimulant of the phenethylamine class. It contains the amphetamines dextroamphetamine saccharate, amphetamine aspartate, dextroamphetamine sulfate, and amphetamine sulfate. It is taken by mouth.
In therapeutic doses, Adderall causes emotional and cognitive effects such as euphoria, change in sex drive, increased wakefulness, and improved cognitive control. At these doses, it induces physical effects such as a faster reaction time, fatigue resistance, and increased muscle strength. In contrast, much larger doses of Adderall can impair cognitive control, cause rapid muscle breakdown, provoke panic attacks, or induce psychosis (e.g., paranoia, delusions, hallucinations). The side effects vary widely among individuals but most commonly include insomnia, dry mouth, loss of appetite and weight loss. The routine use of Adderall at higher-than-prescribed doses poses a significant risk of addiction or dependence due to the pronounced reinforcing effects that are present at high doses. Recreational doses of Adderall are generally much larger than prescribed therapeutic doses and also carry a far greater risk of serious adverse effects.
The two amphetamine enantiomers that compose Adderall, such as Adderall tablets/capsules (levoamphetamine and dextroamphetamine), alleviate the symptoms of ADHD and narcolepsy by increasing the activity of the neurotransmitters norepinephrine and dopamine in the brain, which results in part from their interactions with human trace amine-associated receptor 1 (hTAAR1) and vesicular monoamine transporter 2 (VMAT2) in neurons. Dextroamphetamine is a more potent CNS stimulant than levoamphetamine, but levoamphetamine has slightly stronger cardiovascular and peripheral effects and a longer elimination half-life than dextroamphetamine. The active ingredient in Adderall, amphetamine, shares many chemical and pharmacological properties with the human trace amines, particularly phenethylamine and N-methylphenethylamine, the latter of which is a positional isomer of amphetamine. In 2023, Adderall was the fifteenth most commonly prescribed medication in the United States, with more than 32 million prescriptions.
