Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Selective 5-HT1B/1D receptor agonist; causes vasoconstriction of cranial arteries and inhibition of trigeminal nerve transmission.
Sumatriptan is a selective 5-HT1B/1D receptor agonist, causing vasoconstriction of intracranial arteries and inhibiting trigeminal nerve transmission. Naproxen sodium is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis. The combination provides synergistic relief for migraine by targeting both neurogenic inflammation and vasodilation.
Acute treatment of migraine with or without aura in adults
Acute treatment of migraine with or without aura in adults,Off-label: Acute treatment of cluster headache (sumatriptan component)
40 mg orally once, may repeat after 2 hours if headache recurs; maximum 80 mg/day.
Sumatriptan 85 mg/naproxen sodium 500 mg orally at onset of migraine; maximum one tablet per 24 hours.
Terminal elimination half-life is approximately 4-5 hours in healthy adults. In patients with hepatic impairment, half-life may be prolonged up to 8 hours. The half-life supports a clinical duration suitable for acute migraine treatment, with no accumulation with single doses.
Sumatriptan: 2.5 hours (range 2-4 hours); Naproxen: 12-17 hours (mean 14 hours). Clinical context: Sumatriptan half-life supports short dosing interval; Naproxen half-life allows twice-daily dosing for migraine prevention.
Primarily metabolized by CYP3A4; also minor contribution from CYP2C9, CYP2C19, and CYP2D6.
Sumatriptan is metabolized primarily by monoamine oxidase A (MAO-A) to an indoleacetic acid metabolite. Naproxen sodium is metabolized by hepatic CYP enzymes (CYP1A2, CYP2C9) and other pathways, with glucuronidation.
Approximately 90% of the dose is eliminated in feces, with less than 10% recovered in urine. Renal excretion accounts for about 9% of total clearance, primarily as unchanged drug. Biliary/fecal elimination is the major route.
Sumatriptan: 57% renal (22% unchanged), 38% fecal; Naproxen: 95% renal (mostly as conjugated metabolites, <5% unchanged), <5% fecal.
Approximately 85% bound to plasma proteins, primarily albumin and alpha-1-acid glycoprotein.
Sumatriptan: 14-21% (primarily albumin); Naproxen: >99% (albumin, extensively bound).
Volume of distribution is approximately 1.4 L/kg (range 1.0-2.0 L/kg), indicating extensive distribution into tissues beyond total body water.
Sumatriptan: 2.4 L/kg (suggests extensive tissue distribution); Naproxen: 0.16 L/kg (confined primarily to plasma and synovial fluid).
Oral bioavailability is approximately 50% (range 30-70% due to first-pass metabolism) for the tablet formulation. Absolute bioavailability is moderate due to presystemic clearance.
Sumatriptan: Oral 15% (due to first-pass metabolism), subcutaneous 96%, intranasal 17%; Naproxen: Oral >95% (nearly complete).
No dose adjustment required for mild to moderate renal impairment; contraindicated in severe renal impairment (Cr Cl <10 m L/min).
Contraindicated in severe renal impairment (Cr Cl <30 m L/min); no adjustment recommended for mild to moderate impairment.
Contraindicated in severe hepatic impairment (Child-Pugh C); no adjustment for mild to moderate impairment.
Contraindicated in severe hepatic impairment (Child-Pugh class C); not recommended in moderate impairment (Child-Pugh class B); no adjustment for mild (Child-Pugh class A).
Not established; safety and efficacy in patients <18 years not studied.
Not recommended for patients under 18 years due to safety and efficacy not established.
Use with caution due to potential decreased hepatic/renal function; consider lower starting dose (20 mg).
Not recommended in patients ≥65 years due to increased risk of adverse events; no specific dosing adjustments available.
No FDA boxed warning.

Grapefruit and grapefruit juice should be avoided as they inhibit CYP3A4, increasing eletriptan exposure and risk of adverse effects. No other significant food interactions reported.
No specific food restrictions, but avoid alcohol due to increased GI bleeding risk. May take with or without food. Food may delay absorption slightly but does not affect efficacy.
Limited human data; animal studies show no teratogenicity at clinically relevant doses. First trimester: risk cannot be excluded; second/third trimester: no known increased risk. Avoid in third trimester due to possible uterine atony or decreased placental perfusion.
Sumatriptan: Human data do not show increased risk of major birth defects overall, but limited data in first trimester; animal studies show embryo/fetal toxicity at high doses. Naproxen: NSAIDs should be avoided after 30 weeks gestation due to risk of premature closure of ductus arteriosus and oligohydramnios; avoid in first and second trimesters unless clearly needed due to potential association with cardiac defects and miscarriage.
Excreted into breast milk in low amounts (M/P ratio unknown). Relative infant dose estimated at <1% of maternal weight-adjusted dose. Considered compatible with breastfeeding; monitor infant for irritability and sleep disturbance.
Sumatriptan: Excreted in breast milk in low amounts (M/P ratio 4.9); infant dose about 3.5% of maternal weight-adjusted dose; limited data show no adverse effects. Naproxen: Excreted in breast milk (M/P ratio 0.01-0.17); infant dose about 1-2% of maternal dose; use caution in premature infants or with prolonged use due to potential NSAID effects.
No specific dose adjustment recommended; pharmacokinetic changes in pregnancy (increased volume of distribution, clearance) may reduce efficacy, but standard dosing remains safe. Consider lowest effective dose.
Sumatriptan: No dose adjustment recommended based on pharmacokinetic changes; however, consider lowest effective dose and avoid if possible first trimester. Naproxen: Avoid in pregnancy; if essential, use lowest effective dose for shortest duration. No pharmacokinetic data necessitating dose adjustment, but third trimester use is contraindicated.
Eletriptan has higher lipophilicity and longer half-life than sumatriptan, potentially offering better CNS penetration and sustained efficacy. Contraindicated within 24 hours of other triptans or ergotamines. Avoid in patients with severe hepatic impairment (Child-Pugh C) as metabolism is CYP3A4-dependent. Maximum single dose 40 mg; may repeat after 2 hours if no response, but do not exceed 80 mg/day. Onset typically within 30 minutes; if first dose fails, consider alternative therapy for subsequent attacks.
Combination tablet provides dual mechanism: sumatriptan (5-HT1B/1D agonist) and naproxen sodium (NSAID). Onset within 30 minutes. Maximum single dose: sumatriptan 85 mg/naproxen 500 mg. Risk of serotonin syndrome with other serotonergic drugs. Avoid in patients with ischemic heart disease, cerebrovascular disease, uncontrolled hypertension, or history of GI bleeding. Contraindicated within 24 hours of ergot alkaloids or other triptans. Renal dose adjustment necessary for Cr Cl <30 m L/min. Use lowest effective dose for shortest duration. Assess cardiovascular risk before prescribing. May cause drowsiness or dizziness.

"Eletriptan, a 5-HT1B/1D receptor agonist used for migraine, and ondansetron, a 5-HT3 receptor antagonist antiemetic, both increase serotonergic activity via different mechanisms. Concurrent use may lead to excessive serotonin accumulation, potentially triggering serotonin syndrome, characterized by neuromuscular excitation, autonomic instability, and altered mental status. While the interaction is mechanistically plausible, clinical reports are rare, and caution is advised particularly in patients on multiple serotonergic agents."
"Concomitant use of eletriptan, a 5-HT1B/1D receptor agonist, with maprotiline, a tetracyclic antidepressant that inhibits serotonin reuptake, may result in additive serotonergic effects. This increases the risk of serotonin syndrome, a potentially life-threatening condition characterized by neuromuscular excitation, autonomic instability, and altered mental status. Patients combining these agents require close monitoring for symptoms such as hyperthermia, clonus, hyperreflexia, and agitation."
"Concomitant use of eletriptan and almotriptan, both triptan-class 5-HT1B/1D receptor agonists, increases the risk of serotonin syndrome and additive vasoconstriction, including coronary vasospasm. Excessive serotonergic activity may lead to neuromuscular excitation, autonomic instability, and altered mental status, while additive arterial vasoconstriction can precipitate severe hypertension or ischemic events, especially in patients with cardiovascular risk factors."
"Naproxen and meloxicam are both nonsteroidal anti-inflammatory drugs (NSAIDs) that inhibit cyclooxygenase (COX) enzymes, leading to decreased synthesis of prostaglandins, prostacyclin, and thromboxanes. Concomitant use increases the risk of dose-dependent adverse effects, particularly gastrointestinal ulceration, bleeding, and perforation, as well as renal impairment, due to additive inhibition of protective prostaglandins in the gut and kidney. Clinically, this combination may result in acute kidney injury, anemia from occult gastrointestinal bleeding, or life-threatening perforation, especially in elderly patients or those with pre-existing renal disease or peptic ulcer history."
"Bevantolol, a beta-1 selective adrenergic receptor antagonist, reduces cardiac output and suppresses renin release, thereby lowering blood pressure. Naproxen, a nonsteroidal anti-inflammatory drug (NSAID), inhibits cyclooxygenase (COX) enzymes, leading to decreased synthesis of vasodilatory prostaglandins and enhanced sodium and water retention. The net effect is an attenuation of bevantolol's antihypertensive efficacy, potentially resulting in elevated blood pressure and reduced cardiovascular protection."
"Betaxolol, a beta-1 selective adrenergic receptor antagonist, may reduce the antihypertensive efficacy of naproxen, a nonsteroidal anti-inflammatory drug (NSAID). Naproxen inhibits cyclooxygenase (COX) enzymes, leading to decreased synthesis of vasodilatory prostaglandins (e.g., prostacyclin) in the renal and vascular endothelium. This can result in sodium and fluid retention, increased systemic vascular resistance, and blunting of the blood pressure-lowering effects of beta-blockers like betaxolol, potentially compromising hypertension control."
