Amphetamine Adderall is a prescription medication whose primary active ingredients are mixed amphetamine salts—specifically, a combination of amphetamine and dextroamphetamine. It’s classified as a Schedule II controlled substance in the US due to its high potential for abuse and dependence. Amphetamines are central nervous system (CNS) stimulants that increase dopamine and norepinephrine levels in the brain.

Medical Uses

• Primary FDA-approved uses:
  • Treatment of Attention Deficit Hyperactivity Disorder (ADHD) in children (ages 3+), adolescents, and adults.
  • Treatment of narcolepsy (a sleep disorder causing excessive daytime sleepiness).
• It works by enhancing focus, attention, and impulse control while reducing hyperactivity. Effects typically last 4–12 hours depending on the formulation (immediate-release or extended-release like Adderall XR).

Evidence: Clinical trials (e.g., MTA study, 1999) show Adderall improves ADHD symptoms in ~70–80% of patients, outperforming placebo. Long-term studies (e.g., NIMH follow-ups) confirm sustained benefits with proper use.

How It Works (Mechanism)

Amphetamines like those in Adderall:

1. Block reuptake of dopamine and norepinephrine.
2. Promote their release from neurons.
3. Inhibit monoamine oxidase (MAO), prolonging neurotransmitter activity.

This leads to heightened alertness and motivation. Blood-brain barrier penetration is rapid (peak plasma levels in 1–3 hours).

Pharmacokinetics:

Dosage and Forms

• Typical doses (ADHD adults): 5–40 mg/day, split doses.
• Forms: Tablets (5, 7.5, 10, 12.5, 15, 20, 30 mg) or capsules (XR versions).
• Always prescribed; generics available (e.g., amphetamine/dextroamphetamine).

Do not self-medicate—requires doctor supervision due to risks.

Side Effects and Risks

Common (10–30% of users):

• Insomnia, dry mouth, appetite loss, weight loss, anxiety, increased heart rate/blood pressure.

Serious risks:

• Cardiovascular: Hypertension, arrhythmias (contraindicated in heart disease).
• Psychiatric: Psychosis, mania (especially at high doses).
• Dependence: Tolerance builds quickly; withdrawal includes fatigue, depression.
• Overdose: Seizures, hyperthermia, stroke (LD50 ~20–50 mg/kg in animals; human fatal doses vary).

Interactions: Avoid with MAOIs, SSRIs (serotonin syndrome risk), alcohol, or caffeine.

Evidence: FDA black-box warning for abuse potential. CDC data shows ~16,000 US overdose deaths involving stimulants (2021), many non-medical use.

Non-Medical Use (Recreational)

Often abused for “study drugs,” euphoria, or weight loss. Street names: Addy, speed. Crushed/snorted for faster high, but increases risks (nasal damage, overdose).

Detection: Urine tests detect 1–3 days (chronic use: weeks); hair tests up to 90 days.

Legal Status

Illicit possession/manufacture is illegal (e.g., US penalties: up to 20 years prison for trafficking).

Alternatives

• Non-stimulants: Atomoxetine (Strattera), guanfacine.
• Other stimulants: Ritalin (methylphenidate), Vyvanse (lisdexamfetamine prodrug, lower abuse potential).

Key Fact: Adderall isn’t “just amphetamine”—it’s a specific 75:25 ratio of dextro- to levoamphetamine for balanced effects.
