Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Adderall 10 contains a mixture of amphetamine salts (dextroamphetamine and levoamphetamine). Amphetamines are non-catecholamine sympathomimetic amines that promote the release of dopamine and norepinephrine from presynaptic neurons, inhibit their reuptake, and inhibit monoamine oxidase activity, thereby increasing extracellular levels of these neurotransmitters in the central nervous system.
Binds bile acids in the intestine, forming an insoluble complex that is excreted in feces, thereby reducing enterohepatic circulation and increasing hepatic conversion of cholesterol to bile acids, lowering serum LDL cholesterol.
Attention Deficit Hyperactivity Disorder (ADHD),Narcolepsy
Primary hypercholesterolemia (FDA-approved adjunct to diet),Pruritus associated with partial biliary obstruction,Pseudomembranous enterocolitis (off-label, as colestipol binds Clostridium difficile toxins),Digitoxin toxicity (off-label, to interrupt enterohepatic circulation),Bile acid malabsorption (off-label)
10 mg orally once daily in the morning, with or without food; may increase by 5-10 mg weekly based on tolerability and response; usual effective dose 10-40 mg/day divided into 2-3 doses; maximum 60 mg/day.
Initial: 5 g orally once daily or 2.5 g twice daily; increase gradually by 5 g/day at 1-2 month intervals; maintenance: 5-30 g/day divided once or twice daily; maximum: 30 g/day.
Terminal elimination half-life: dextroamphetamine 9-11 hours, levoamphetamine 11-14 hours (Adderall is a mixed salt). In adults, mean half-life ~10 hours; in children, slightly shorter (6-8 hours). Clinical context: steady-state reached in 2-3 days; dosing interval typically 4-6 hours for immediate-release.
Not applicable as colestipol is not absorbed; it acts locally in the gastrointestinal tract and has no systemic half-life.
Amphetamine is metabolized primarily in the liver via cytochrome P450 enzymes, including CYP2D6, and undergoes deamination and oxidation to form inactive metabolites including 4-hydroxyamphetamine and norephedrine.
Not metabolized; not absorbed systemically.
Renal: 70-80% (30-40% as unchanged amphetamine; remainder as deaminated and hydroxylated metabolites). Fecal: minimal (<5%). Biliary: negligible. Urinary p H affects excretion: acidic urine increases elimination, alkaline urine decreases.
Colestipol hydrochloride is not absorbed systemically; it is excreted entirely in the feces as the intact polymer, without undergoing metabolism. No renal or biliary elimination occurs.
Amphetamine: 15-40% bound to plasma proteins (primarily albumin). Binding is not extensive, thus significant free fraction available for distribution.
Not applicable; the drug is not absorbed and does not bind to plasma proteins.
Apparent Vd: 3.0-4.0 L/kg (for total amphetamine). High Vd indicates extensive tissue distribution, including brain. Clinical meaning: loading dose may be needed for rapid effect; distribution half-life ~1 hour.
Not applicable; colestipol is not absorbed and remains within the gastrointestinal lumen.
Oral immediate-release: 100% (well-absorbed; first-pass metabolism minimal). Food delays absorption but does not affect extent. Extended-release: bioavailability similar to immediate-release with modified release profile.
0% for systemic absorption; it is non-absorbable and acts locally in the intestine.
e GFR 15-29 m L/min: reduce dose by 50% and monitor for toxicity; e GFR <15 m L/min or dialysis: avoid use due to risk of accumulation; consider alternative therapy.
No specific dose adjustment recommended; use with caution in severe renal impairment due to potential for hyperchloremic metabolic acidosis.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: avoid use due to decreased clearance and increased risk of toxicity.
No specific dose adjustment recommended; caution in severe hepatic impairment due to possible decreased cholesterol synthesis.
Children 3-5 years: 2.5 mg orally once daily; may increase by 2.5 mg weekly; usual range 2.5-20 mg/day divided 1-2 times. Children 6 years and older: initial 5 mg once daily; may increase by 5 mg weekly; usual range 5-40 mg/day divided 1-3 times; maximum 40 mg/day.
Not established for children <10 years; for ≥10 years, initial: 5 g orally once daily; increase gradually to 5-20 g/day divided once or twice daily.
Initiate at 2.5-5 mg orally once daily; titrate slowly in increments of 2.5-5 mg weekly; monitor for cardiovascular effects, insomnia, and weight loss; maximum 40 mg/day.
No specific dose adjustment; monitor for gastrointestinal adverse effects and potential interactions with other medications due to altered GI motility and polypharmacy.
Potential for abuse and dependence. Amphetamines have a high potential for abuse, which may lead to dependence and serious cardiovascular adverse events. Misuse may cause sudden death and serious cardiovascular events.
No FDA black box warning.
Serious cardiovascular events including sudden death in patients with pre-existing structural cardiac abnormalities or other serious heart problems.,Blood pressure and heart rate increase; caution in hypertension and other cardiovascular conditions.,Psychiatric adverse events including exacerbation of psychosis, mania, and aggression.,Long-term suppression of growth in pediatric patients.,Peripheral vasculopathy including Raynaud's phenomenon.,Seizures: may lower seizure threshold.,Serotonin syndrome risk when co-administered with serotonergic drugs.
May cause hypertriglyceridemia,Risk of vitamin K deficiency and bleeding (due to bile acid binding),May impair absorption of fat-soluble vitamins (A, D, E, K),May cause constipation or fecal impaction (especially in elderly),May interfere with absorption of other drugs (e.g., warfarin, thyroid hormones, digoxin); separate administration by at least 1 hour or as specified
Advanced arteriosclerosis,Symptomatic cardiovascular disease,Moderate to severe hypertension,Hyperthyroidism,Known hypersensitivity or idiosyncrasy to sympathomimetic amines,Glaucoma,Agitated states,History of drug abuse,During or within 14 days following the administration of monoamine oxidase inhibitors (hypertensive crises may occur)
Hypersensitivity to colestipol hydrochloride or any component,Complete biliary obstruction,Phenylketonuria (if formulation contains aspartame)
High-fat meals can delay absorption; avoid acidic foods (e.g., citrus, cola) within 1 hour of dosing as they decrease absorption. Avoid caffeine; may increase stimulant effects.
Colestipol can bind to dietary fats and fat-soluble vitamins (A, D, E, K). Take supplements at least 1 hour before or 4-6 hours after colestipol. High-fiber foods may reduce binding but are generally encouraged to prevent constipation. Avoid grapefruit juice? No significant interaction.
Pregnancy Category C. First trimester: potential increased risk of congenital malformations (e.g., gastroschisis, oral clefts) based on limited human data. Second and third trimesters: risk of fetal growth restriction, preterm delivery, and neonatal withdrawal symptoms (irritability, poor feeding).
Colestipol hydrochloride is not absorbed systemically, thus no direct fetal exposure. No teratogenic risk expected. First trimester: minimal risk. Second/third trimester: no known adverse fetal effects.
Excreted into breast milk; relative infant dose estimated at 2-4% of maternal weight-adjusted dose. M/P ratio not well established. Manufacturer recommends caution; potential for infant agitation, insomnia, and growth suppression.
Colestipol is not absorbed systemically and not excreted into breast milk. Compatible with breastfeeding. M/P ratio not applicable.
Increased plasma volume and enhanced hepatic metabolism may reduce amphetamine levels; dose adjustments should be individualized based on clinical response, but controlled studies lacking. Avoid abrupt discontinuation due to risk of withdrawal symptoms in mother and neonate.
No dose adjustment required due to lack of systemic absorption. Monitor for potential fat-soluble vitamin deficiency and supplement if needed.
Adderall 10 mg contains immediate-release amphetamine salts. Onset of action is 30-60 minutes, duration 4-6 hours. Monitor for appetite suppression, insomnia, and cardiovascular effects. Avoid in patients with structural cardiac abnormalities or history of substance abuse. Use with caution in hypertension or hyperthyroidism. Drug holidays may reduce tolerance.
Colestipol hydrochloride is a bile acid sequestrant used as adjunctive therapy for primary hyperlipidemia. It may increase triglyceride levels; monitor triglycerides before initiation. Administer other medications 1 hour before or 4-6 hours after colestipol to reduce absorption interference. Use with caution in constipation-prone patients; encourage high-fiber diet and adequate fluid intake. Can bind thyroxine, warfarin, digoxin, and fat-soluble vitamins.
