AZILSARTAN MEDOXOMIL vs ADDERALL 10
Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Angiotensin II receptor blocker (ARB) that selectively inhibits angiotensin II binding to AT1 receptors, reducing vasoconstriction, aldosterone secretion, and sympathetic activity.
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.
Treatment of hypertension (FDA-approved),Off-label: heart failure, diabetic nephropathy
Attention Deficit Hyperactivity Disorder (ADHD),Narcolepsy
40 mg orally once daily. May increase to 80 mg once daily if needed.
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.
Terminal half-life approximately 11 hours; supports once-daily dosing with sustained antihypertensive effect over 24 hours.
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.
Primarily metabolized by CYP2C9 to inactive metabolites; also undergoes esterase-mediated hydrolysis to azilsartan.
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.
Biliary/fecal (55% unchanged), renal (42% as inactive metabolites, <1% unchanged)
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.
High (>99%) to serum albumin.
Amphetamine: 15-40% bound to plasma proteins (primarily albumin). Binding is not extensive, thus significant free fraction available for distribution.
Vd of about 16 L (0.23 L/kg for a 70 kg individual); indicates limited extravascular distribution.
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.
Oral bioavailability approximately 60% under fed conditions (food reduces absorption); absolute bioavailability not determined in humans.
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.
No dose adjustment required for GFR ≥15 m L/min/1.73 m². Not recommended for GFR <15 m L/min/1.73 m² due to lack of data.
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 dose adjustment required for mild to moderate hepatic impairment (Child-Pugh A and B). Not recommended for severe hepatic impairment (Child-Pugh C) due to lack of data.
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.
Not approved for use in pediatric patients (safety and efficacy not established).
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.
No specific dose adjustment recommended; initiate at 40 mg once daily. Monitor renal function and blood pressure carefully due to increased sensitivity.
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 significant food interactions; can be taken with or without food. Avoid excessive potassium intake from high-potassium foods (e.g., bananas, oranges, spinach, potatoes) or potassium-containing salt substitutes. Limit alcohol intake as it may increase blood pressure or cause dizziness.
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.
First trimester: Limited human data; animal studies show no teratogenicity. Second and third trimesters: Drugs acting directly on the renin-angiotensin system can cause fetal oligohydramnios, fetal renal dysfunction, skull ossification defects, and neonatal anuria, hypotension, and death.
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).
No data on presence in human milk. Manufacturer recommends discontinuing breastfeeding or drug due to potential risk. M/P ratio unknown.
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.
No dose adjustments during pregnancy; however, use is contraindicated in second and third trimesters due to fetal toxicity. If exposure occurs, discontinue as soon as possible.
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.
Azilsartan medoxomil has the highest affinity for AT1 receptors among ARBs; may cause a rapid decrease in blood pressure in volume-depleted patients; avoid use in pregnancy (Category D); monitor renal function and serum potassium; less CYP450 interaction potential than losartan or irbesartan; can be taken without regard to meals; dose adjustment not required in mild-to-moderate hepatic impairment.

"The combination of azilsartan medoxomil, an angiotensin II receptor blocker (ARB), and fenbufen, a nonsteroidal anti-inflammatory drug (NSAID), can lead to a significant reduction in the antihypertensive and cardioprotective effects of azilsartan. NSAIDs inhibit cyclooxygenase enzymes, reducing prostaglandin synthesis, which diminishes the vasodilatory and natriuretic actions that support blood pressure control mediated by ARBs. This interaction may result in loss of blood pressure control, increased risk of renal impairment (especially in volume-depleted or elderly patients), and potential antagonism of the renal protective effects of ARBs in conditions like heart failure or chronic kidney disease."
"Oxprenolol, a non-selective beta-blocker, may attenuate the compensatory sympathetic response to Azilsartan medoxomil-induced hypotension, potentially leading to an excessive drop in blood pressure. This combination can also result in reduced cardiac output due to additive negative chronotropic effects, increasing the risk of bradycardia and heart block. Clinically, patients may experience severe hypotension, dizziness, syncope, or exacerbated heart failure symptoms."
"The combination of timolol, a non-selective beta-blocker, with azilsartan medoxomil, an angiotensin II receptor blocker (ARB), may lead to an increased risk of hypotension, bradycardia, and additive antihypertensive effects. Timolol can antagonize the compensatory sympathetic response to azilsartan-induced vasodilation, potentially resulting in excessive blood pressure reduction. Additionally, both drugs can affect renal perfusion, raising the risk of renal impairment in susceptible patients."
