Sumatriptan is a selective 5-HT1B/1D receptor agonist, causing vasoconstriction of cranial blood vessels and inhibition of trigeminal nerve transmission. Naproxen sodium is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis.
Selective 5-HT1B/1D receptor agonist; causes vasoconstriction of cranial arteries and inhibition of trigeminal nerve transmission.
Acute treatment of migraine attacks with or without aura in adults
Acute treatment of migraine with or without aura in adults
Sumatriptan 85 mg / naproxen sodium 500 mg orally at onset of migraine; may repeat once after 2 hours if needed, not to exceed 2 tablets in 24 hours.
40 mg orally once, may repeat after 2 hours if headache recurs; maximum 80 mg/day.
Sumatriptan: terminal half-life approximately 2.5 hours (range 1.5–4.6 hours); clinically, short half-life limits duration of action. Naproxen sodium: terminal half-life approximately 12–17 hours (mean 14 hours); long half-life allows twice-daily dosing and sustained analgesic effect.
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 is primarily metabolized by monoamine oxidase A (MAO-A). Naproxen is metabolized by CYP2C9.
Primarily metabolized by CYP3A4; also minor contribution from CYP2C9, CYP2C19, and CYP2D6.
Sumatriptan: renal excretion of unchanged drug and metabolites (primarily indole acetic acid analogue) accounts for approximately 60% of elimination; fecal/biliary excretion accounts for about 40%. Naproxen sodium: renal excretion of unchanged drug (approximately 60%) and glucuronide conjugates (about 40%); less than 5% is excreted fecally.
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: protein binding approximately 14–21% (low binding). Naproxen sodium: protein binding >99% (highly bound to albumin).
Approximately 85% bound to plasma proteins, primarily albumin and alpha-1-acid glycoprotein.
Sumatriptan: Vd approximately 2.2 L/kg (indicates extensive tissue distribution). Naproxen sodium: Vd approximately 0.16 L/kg (low Vd, consistent with high protein binding and limited tissue distribution).
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: oral bioavailability approximately 15% (due to first-pass metabolism); subcutaneous injection 96%; intranasal approximately 17%. Naproxen sodium: oral bioavailability >95% (well absorbed).
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.
Contraindicated if GFR <30 m L/min; for GFR 30-50 m L/min, caution with naproxen component; no specific dose adjustment recommended for sumatriptan.
No dose adjustment required for mild to moderate renal impairment; contraindicated in severe renal impairment (Cr Cl <10 m L/min).
Contraindicated in severe hepatic impairment (Child-Pugh class C); sumatriptan maximum dose 50 mg per dose in moderate impairment (Child-Pugh class B); naproxen sodium avoid in severe impairment.
Contraindicated in severe hepatic impairment (Child-Pugh C); no adjustment for mild to moderate impairment.
Not approved for patients <12 years; for adolescents 12-17 years, single dose of sumatriptan 85 mg / naproxen sodium 500 mg (as adult formulation) per clinical judgment, not to exceed 1 dose in 24 hours.
Not established; safety and efficacy in patients <18 years not studied.
Avoid use in elderly due to increased risk of cardiovascular events, gastrointestinal bleeding, and renal impairment; if necessary, use lowest effective dose for shortest duration.
Use with caution due to potential decreased hepatic/renal function; consider lower starting dose (20 mg).
Cardiovascular and gastrointestinal risks: NSAIDs increase the risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. Risk increases with duration of use. NSAIDs also increase the risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. Sumatriptan is contraindicated in patients with history of coronary artery disease or risk factors. Do not use within 24 hours of another 5-HT1 agonist or ergotamine-containing medication.

Avoid alcohol (may exacerbate migraine and increase GI irritation). Limit caffeine intake (can trigger migraine). No specific food restrictions, but maintain hydration.
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.
Sumatriptan: Limited data; no increased risk of major congenital malformations observed in cohort studies. Avoid use in third trimester due to potential uterine vasoconstriction and reduced placental perfusion. Naproxen: First trimester – potential increased risk of cardiac defects; second trimester – generally safe with caution; third trimester – contraindicated due to risk of premature ductus arteriosus closure, oligohydramnios, and fetal renal dysfunction.
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: Excreted in breast milk with estimated relative infant dose of 3.5% of maternal weight-adjusted dose; M/P ratio not well defined. Naproxen: Excreted in breast milk with M/P ratio approximately 0.01; relative infant dose <1% of maternal dose. Both considered compatible with breastfeeding with monitoring for infant adverse effects.
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.
No specific dose adjustments recommended for sumatriptan in pregnancy; however, limited data suggest no significant pharmacokinetic changes. Naproxen: Clearance may increase in later pregnancy; dose adjustments not well studied. Avoid naproxen in third trimester.
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/naproxen sodium is contraindicated within 24 hours of another triptan or ergotamine. Naproxen dose is fixed; avoid additional NSAIDs to prevent GI bleeding or renal impairment. Use with caution in patients with cardiovascular risk factors. Onset of action is 10-30 minutes; advise against driving if dizziness occurs.
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.

"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."
"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."
