Angiotensin II receptor blocker (ARB) that selectively inhibits angiotensin II binding to AT1 receptors, reducing vasoconstriction, aldosterone secretion, and sympathetic activity.
Adderall contains mixed amphetamine salts that increase synaptic levels of dopamine and norepinephrine by inhibiting their reuptake and promoting release from presynaptic terminals.
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.
Initial: 5 mg orally once or twice daily; increase by 5 mg increments weekly; usual maintenance: 20-30 mg daily in divided doses; maximum: 40 mg/day
Terminal half-life approximately 11 hours; supports once-daily dosing with sustained antihypertensive effect over 24 hours.
Terminal elimination half-life: d-amphetamine 10-13 hours, l-amphetamine 13-15 hours; in adults (children: 6-8 hours). The longer half-life allows for once-daily dosing.
Primarily metabolized by CYP2C9 to inactive metabolites; also undergoes esterase-mediated hydrolysis to azilsartan.
Primarily hepatic via CYP2D6, with minor contributions from CYP1A2, CYP2B6, and CYP3A4.
Biliary/fecal (55% unchanged), renal (42% as inactive metabolites, <1% unchanged)
Approximately 30-40% of a dose is excreted unchanged in urine; the remainder is metabolized primarily by oxidative deamination and aromatic hydroxylation. Biliary/fecal elimination accounts for less than 5%.
High (>99%) to serum albumin.
Approximately 20-25% bound to plasma proteins, mainly albumin and alpha-1-acid glycoprotein.
Vd of about 16 L (0.23 L/kg for a 70 kg individual); indicates limited extravascular distribution.
Vd: 3-4 L/kg (approximately 210-280 L for a 70 kg adult). This indicates extensive tissue distribution and penetration into the central nervous system.
Oral bioavailability approximately 60% under fed conditions (food reduces absorption); absolute bioavailability not determined in humans.
Oral immediate-release: approximately 75-100%; oral extended-release: approximately 94% relative to immediate-release. Food does not significantly affect absorption but may delay peak concentration.

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.
Avoid high-fat meals as they delay absorption; avoid acidic foods (e.g., citrus) and vitamin C supplements within 1 hour of dosing as they decrease absorption; limit caffeine and other stimulants to avoid additive cardiovascular 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: No well-controlled studies, but potential for congenital malformations not definitively established. Second and third trimesters: Increased risk of premature delivery, low birth weight, and neonatal withdrawal symptoms (e.g., dysphoria, agitation, lassitude). Chronic use may lead to neonatal toxicity.
No data on presence in human milk. Manufacturer recommends discontinuing breastfeeding or drug due to potential risk. M/P ratio unknown.
Excreted in breast milk. M/P ratio unknown. Potential for stimulant effects in infant (e.g., irritability, poor feeding, insomnia). Caution advised; consider alternative feeding methods.
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.
No established dosing guidelines. Due to increased plasma volume and clearance, dose may need titration to clinical effect, but avoid supratherapeutic doses. Use lowest effective dose.
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.
For ADHD: start low, go slow; monitor weight and height in children; avoid late doses to prevent insomnia; check for abuse/diversion; screen for bipolar disorder and hypertension; consider urine drug screen before prescribing; avoid MAOIs within 14 days; use with caution in seizure disorders and glaucoma.

"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."
