Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
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.
Fentanyl is a potent mu-opioid receptor agonist, producing analgesia and sedation by activating G-protein coupled opioid receptors in the central nervous system.
Acute treatment of migraine attacks with or without aura in adults
Management of breakthrough pain in cancer patients aged 18 and older who are already receiving and tolerant to around-the-clock opioid therapy for their underlying persistent cancer pain.
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.
For breakthrough pain in opioid-tolerant patients: initial dose 100 mcg sublingual tablet, titrate across strengths (100, 200, 300, 400, 600, 800 mcg) as needed; maximum 2 doses per episode, minimum 2 hours between episodes.
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: 6-10 hours (mean 8 hours); prolonged in elderly and hepatic impairment
Sumatriptan is primarily metabolized by monoamine oxidase A (MAO-A). Naproxen is metabolized by CYP2C9.
Hepatic metabolism primarily via CYP3A4; major metabolites include norfentanyl (inactive) and other minor metabolites.
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.
Renal: ~70% as metabolites (primarily fentanyl conjugates and norfentanyl), ~10% unchanged; Fecal: ~9%; Biliary: minimal
Sumatriptan: protein binding approximately 14–21% (low binding). Naproxen sodium: protein binding >99% (highly bound to albumin).
80-85% bound primarily to 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).
4-6 L/kg; large Vd indicates extensive tissue distribution
Sumatriptan: oral bioavailability approximately 15% (due to first-pass metabolism); subcutaneous injection 96%; intranasal approximately 17%. Naproxen sodium: oral bioavailability >95% (well absorbed).
Sublingual: 70-90% (mean 80%); buccal: 50-65%; oral: ~30% due to first-pass metabolism
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 specific GFR-based dose adjustment recommended; use caution in severe renal impairment (Cr Cl <30 m L/min) due to potential accumulation of fentanyl.
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.
For Child-Pugh Class A or B: no adjustment required; for Child-Pugh Class C: reduce dose and monitor closely for toxicity due to reduced clearance.
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 approved for pediatric patients <18 years; safety and efficacy not established.
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.
Initiate at the lowest available dose (100 mcg) and titrate cautiously; elderly patients may have altered pharmacokinetics and increased sensitivity to fentanyl.
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.
Risk of respiratory depression, addiction, abuse, and misuse; risk of accidental ingestion; risk of medication errors resulting in fatal overdose; life-threatening respiratory depression in opioid-non-tolerant patients; risk of opioid analgesic drug interactions with CNS depressants; risk of neonatal opioid withdrawal syndrome with prolonged use during pregnancy.
Cardiovascular events: Myocardial ischemia, infarction, arrhythmia, and death reported with sumatriptan. NSAIDs increase risk of serious cardiovascular thrombotic events.,Gastrointestinal effects: NSAIDs increase risk of GI bleeding, ulceration, and perforation.,Excessive use: Medication overuse headache may occur.,Serotonin syndrome: Risk with concurrent use of serotonergic drugs.,Renal effects: NSAIDs can cause renal toxicity.,Hypertension: Sumatriptan may increase blood pressure.,Anaphylactic reactions: Serious allergic reactions including anaphylaxis reported with sumatriptan.,Hepatic effects: NSAIDs may cause liver enzyme elevations.
Respiratory depression, QT prolongation, serotonin syndrome, adrenal insufficiency, severe hypotension, seizures, biliary tract disease, gastrointestinal obstruction, withdrawal syndrome, and risk of overdose with alcohol or other CNS depressants.
History of coronary artery disease (CAD) or coronary artery vasospasm,Wolff-Parkinson-White syndrome or other cardiac accessory pathway disorders,History of stroke or transient ischemic attack,Peripheral vascular disease,Ischemic bowel disease,Uncontrolled hypertension,Within 24 hours of treatment with another 5-HT1 agonist (e.g., triptans) or ergotamine-containing medications,Concomitant use or within 2 weeks of MAO-A inhibitor,History of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs,In the setting of coronary artery bypass graft (CABG) surgery,Third trimester of pregnancy
Hypersensitivity to fentanyl or any components; opioid-non-tolerant patients; acute or severe bronchial asthma; known or suspected gastrointestinal obstruction; concurrent use of MAOIs or within 14 days of discontinuation.
Avoid alcohol (may exacerbate migraine and increase GI irritation). Limit caffeine intake (can trigger migraine). No specific food restrictions, but maintain hydration.
Avoid grapefruit and grapefruit juice during treatment as they inhibit CYP3A4, increasing fentanyl exposure. No other significant food interactions; however, avoid alcohol due to additive CNS depressant effects. Maintain consistent meal timing relative to dosing to minimize variability.
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.
FDA Pregnancy Category C. First trimester: Inadequate human data; opioid analgesics are not associated with major malformations but may cause neural tube defects at high doses in animal studies. Second trimester: No specific malformation risk. Third trimester: Prolonged use can cause neonatal opioid withdrawal syndrome (NOWS) and respiratory depression at birth.
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.
Minimal excretion into breast milk; M/P ratio not reported. Fentanyl is poorly absorbed orally, making significant infant exposure unlikely. Monitor infant for sedation, respiratory depression, and poor feeding. Avoid use in breastfeeding mothers with opioid dependence or high doses.
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.
Pregnancy increases clearance and volume of distribution, potentially reducing drug levels. Dose adjustments may be needed: initiate with lower doses and titrate to effect; consider increasing frequency or using breakthrough doses. Monitor for inadequate analgesia. Avoid abrupt discontinuation; taper if stopping.
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.
ABSTRAL (fentanyl sublingual spray) is a transmucosal immediate-release fentanyl (TIRF) formulation indicated for breakthrough pain in opioid-tolerant patients. Due to high bioavailability (~70%) and rapid onset (peak plasma concentration at 15-30 minutes), initial titration must start with 100 mcg, with dose escalation based on efficacy and tolerability. Weight-based conversion from other fentanyl products is not valid; utilize the provided conversion table. Patients must have a rescue agent (e.g., naloxone) available. Concomitant use with CYP3A4 inhibitors (e.g., ketoconazole, ritonavir) or inducers (e.g., rifampin, carbamazepine) requires dose adjustment. Avoid use in opioid-naïve patients due to risk of respiratory depression.
Take at the first sign of migraine; do not exceed one tablet in 24 hours.,Do not take within 24 hours of other triptans or ergotamine-containing drugs.,Avoid alcohol during migraine attack as it may worsen symptoms.,Report chest tightness, palpitations, or shortness of breath immediately.,Do not drive or operate machinery if feeling dizzy or drowsy.,Inform healthcare provider of all medications, especially blood thinners or antidepressants.
Use only for breakthrough cancer pain while on around-the-clock opioid therapy.,Do not switch from other fentanyl products based on dose; follow specific conversion instructions.,Spray entire dose into mouth; do not swallow or rinse for at least 10 minutes.,Store at room temperature, away from children and pets.,Dispose of unused units via drug take-back program or by flushing down toilet per FDA guidelines.,Never share this medication with others; death may occur.,Seek emergency if severe drowsiness, confusion, or slow breathing occurs.
"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."
