^ Pharmacodynamics
In a healthy volunteer study, 10 days of concomitant administration of naproxen 220 mg once-daily with low-dose immediate-release aspirin (81 mg) showed an interaction with the antiplatelet activity of aspirin as measured by % serum thromboxane B2 inhibition at 24 hours following the day 10 dose [98.7% (aspirin alone) vs 93.1% (naproxen and aspirin)]. The interaction was observed even following discontinuation of naproxen on day 11 (while aspirin dose was continued) but normalized by day 13. In the same study, the interaction was greater when naproxen was administered 30 minutes prior to aspirin [98.7% vs 87.7%] and minimal when aspirin was administered 30 minutes prior to naproxen [98.7% vs 95.4%].
Following administration of naproxen 220 mg twice-daily with low-dose immediate–release aspirin (first naproxen dose given 30 minutes prior to aspirin), the interaction was minimal at 24 h following day 10 dose [98.7% vs 95.7%]. However, the interaction was more prominent after discontinuation of naproxen (washout) on day 11 [98.7% vs 84.3%] and did not normalize completely by day 13 [98.5% vs 90.7%] [see Drug Interactions (7.1)].
^ Dosing In Patients With Hepatic Impairment
Sumatriptan and Naproxen Sodium Tablets is contraindicated in patients with severe hepatic impairment [see Contraindications (4), Use in Specific Populations (8.7), Clinical Pharmacology (12.3)].
In patients with mild to moderate hepatic impairment, the recommended dosage in a 24-hour period is 1 tablet of Sumatriptan and Naproxen Sodium Tablets 10/60 mg [see Use in Specific Populations (8.7), Clinical Pharmacology (12.3)].
Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and Precautions (5)].
^ Patient Counseling Information
Advise the patient to read the FDA-approved patient labeling (Medication Guide) that accompanies each prescription dispensed. Inform patients, families, or their caregivers of the following information before initiating therapy with Sumatriptan and Naproxen Sodium Tablets and periodically during the course of ongoing therapy.
^ Description
Sumatriptan and Naproxen Sodium Tablets contains sumatriptan (as the succinate), a selective 5-hydroxytryptamine1 (5-HT1) receptor subtype agonist, and naproxen sodium, a member of the arylacetic acid group of NSAIDs.
Sumatriptan succinate is chemically designated as 3-[2-(dimethylamino)ethyl]-N-methyl-indole-5-methanesulfonamide succinate (1:1), and it has the following structure:
The empirical formula is C14H21N3O2S∙C4H6O4, representing a molecular weight of 413.5. Sumatriptan succinate is a white to off-white powder that is readily soluble in water and in saline.
Naproxen sodium is chemically designated as (S)-6-methoxy-α-methyl-2-naphthaleneacetic acid, sodium salt, and it has the following structure:
The empirical formula is C14H13NaO3, representing a molecular weight of 252.23. Naproxen sodium is a white-to-creamy white crystalline solid, freely soluble in water at neutral pH.
Each Sumatriptan and Naproxen Sodium Tablets 85/500 mg tablet for oral administration contains 119 mg of sumatriptan succinate equivalent to 85 mg of sumatriptan and 500 mg of naproxen sodium. Each tablet also contains the inactive ingredients croscarmellose sodium, dibasic calcium phosphate, FD&C Blue No. 2, hypromellose, magnesium stearate, microcrystalline cellulose, povidone, sodium bicarbonate, talc, titanium dioxide, and triacetin.
Each Sumatriptan and Naproxen Sodium Tablets 10/60 mg tablet for oral administration contains 14 mg of sumatriptan succinate equivalent to 10 mg of sumatriptan and 60 mg of naproxen sodium. Each tablet also contains the inactive ingredients croscarmellose sodium, dibasic calcium phosphate, FD&C Blue No. 2, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polyvinyl alcohol, povidone, sodium bicarbonate, talc, and titanium dioxide.
^ Drug Reaction With Eosinophilia And Systemic Symptoms (dress)
Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) has been reported in patients taking NSAIDs such as Sumatriptan and Naproxen Sodium Tablets. Some of these events have been fatal or life-threatening. DRESS typically, although not exclusively, presents with fever, rash, lymphadenopathy, and/or facial swelling. Other clinical manifestations may include hepatitis, nephritis, hematological abnormalities, myocarditis, or myositis. Sometimes symptoms of DRESS may resemble an acute viral infection. Eosinophilia is often present. Because this disorder is variable in its presentation, other organ systems not noted here may be involved. It is important to note that early manifestations of hypersensitivity, such as fever or lymphadenopathy, may be present even though rash is not evident. If such signs or symptoms are present, discontinue Sumatriptan and Naproxen Sodium Tablets and evaluate the patient immediately.
^ Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice.
^ Hepatic Impairment
Sumatriptan and Naproxen Sodium Tablets is contraindicated in patients with severe hepatic impairment. For patients with mild or moderate hepatic impairment, the Sumatriptan and Naproxen Sodium Tablets dose should be reduced. [see Contraindications (4), Warnings and Precautions (5.7), and Clinical Pharmacology (12.3)].
^ Pediatric Patients To Years Of Age
The efficacy of Sumatriptan and Naproxen Sodium Tablets in the acute treatment of migraine with or without aura in pediatric patients 12 to 17 years of age was demonstrated in a randomized, double-blind, multicenter, parallel-group, placebo-controlled, multicenter trial comparing 3 doses of Sumatriptan and Naproxen Sodium Tablets and placebo (Study 3). Patients enrolled in this trial were mostly female (59%) and white (81%), with a mean age of 15 years.
Patients were required to have at least a 6-month history of migraine attacks with or without aura usually lasting 3 hours or more when untreated. Following a single-blind, placebo run-in phase, placebo nonresponders were randomized to receive a single dose of either Sumatriptan and Naproxen Sodium Tablets 10/60 mg, 30/180 mg, 85/500 mg, or placebo. Patients were instructed to treat a single migraine attack with headache pain of moderate to severe intensity. No rescue medication was allowed within 2 hours postdose. Patients evaluated their headache pain 2 hours after taking 1 dose of study medication. Two-hour pain free was defined as a reduction in headache severity from moderate or severe pain to no pain at 2 hours postdose.
Results are summarized in Table 5. The percentage of patients who were pain free at 2 hours postdose was significantly greater among patients who received any of the 3 doses of Sumatriptan and Naproxen Sodium Tablets compared with placebo.
The percentage of pediatric patients who remained pain free without use of other medications 2 through 24 hours postdose was significantly greater after administration of a single dose of Sumatriptan and Naproxen Sodium Tablets 85/500 mg compared with placebo. A greater percentage of pediatric patients who received a single dose of 10/60 mg or 30/180 mg remained pain free 2 through 24 hours postdose compared with placebo.
Compared with placebo, the incidence of photophobia and phonophobia was significantly decreased 2 hours after the administration of a single dose of 85/500 mg, whereas, the incidence of nausea was comparable. There was a decreased incidence of photophobia, phonophobia, and nausea 2 hours after single-dose administration of 10/60 mg or 30/180 mg compared with placebo.
^ Gastrointestinal Bleeding, Ulceration, And Perforation
NSAIDs, including naproxen, a component of Sumatriptan and Naproxen Sodium Tablets, cause serious gastrointestinal adverse events including inflammation, bleeding, ulceration, and perforation of the stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with NSAIDs. Only 1 in 5 patients who develop a serious upper gastrointestinal adverse event on NSAID therapy is symptomatic. Upper gastrointestinal ulcers, gross bleeding, or perforation caused by NSAIDs appear to occur in approximately 1% of patients treated daily for 3 to 6 months and in about 2% to 4% of patients treated for 1 year. However, even short-term therapy is not without risk.
Among 3,302 adult patients with migraine who received Sumatriptan and Naproxen Sodium Tablets in controlled and uncontrolled clinical trials, 1 patient experienced a recurrence of gastric ulcer after taking 8 doses over 3 weeks, and 1 patient developed a gastric ulcer after treating an average of 8 attacks per month over 7 months.
^ Overdosage
Patients (N = 670) have received single oral doses of 140 to 300 mg of sumatriptan without significant adverse effects. Volunteers (N = 174) have received single oral doses of 140 to 400 mg without serious adverse events.
Overdose of sumatriptan in animals has been fatal and has been heralded by convulsions, tremor, paralysis, inactivity, ptosis, erythema of the extremities, abnormal respiration, cyanosis, ataxia, mydriasis, salivation, and lacrimation.
Symptoms following acute NSAID overdosages have been typically limited to lethargy, drowsiness, nausea, vomiting and epigastric pain. Gastrointestinal bleeding has occurred. Hypertension, acute renal failure, respiratory depression, and coma have occurred, but were rare [see Warnings and Precautions (5.1, 5.2)].
Manage patients with symptomatic and supportive care following an NSAID overdosage. There are no specific antidotes. Consider emesis and/or activated charcoal (60 to 100 grams in adults, 1 to 2 grams per kg of body weight in pediatric patients) and/or osmotic cathartic in symptomatic patients seen within four hours of ingestion or in patients with a large overdosage (5 to 10 times the recommended dosage). Hemodialysis does not decrease the plasma concentration of naproxen because of the high degree of its protein binding. It is unknown what effect hemodialysis or peritoneal dialysis has on the serum concentrations of sumatriptan. Forced diuresis, alkalinization of urine, hemodialysis, or hemoperfusion may not be useful due to high protein binding.
For additional information about overdosage treatment contact a poison control center (1-800-222-1222).
^ Medication Overuse Headache
Overuse of acute migraine drugs (e.g., ergotamine, triptans, opioids, or a combination of these drugs for 10 or more days per month) may lead to exacerbation of headache (medication overuse headache). Medication overuse headache may present as migraine-like daily headaches, or as a marked increase in frequency of migraine attacks. Detoxification of patients, including withdrawal of the overused drugs, and treatment of withdrawal symptoms (which often includes a transient worsening of headache) may be necessary.
^ Seizures
Seizures have been reported following administration of sumatriptan. Some have occurred in patients with either a history of seizures or concurrent conditions predisposing to seizures. There are also reports in patients where no such predisposing factors are apparent. Sumatriptan and Naproxen Sodium Tablets should be used with caution in patients with a history of epilepsy or conditions associated with a lowered seizure threshold.
^ Serious Skin Reactions
NSAID-containing products can cause serious skin adverse reactions such as exfoliative dermatitis, Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. NSAIDs can also cause fixed drug eruption (FDE). FDE may present as a more severe variant known as generalized bullous fixed drug eruption (GBFDE), which can be life-threatening. These serious events may occur without warning. Inform patients about the signs and symptoms of serious skin reactions and to discontinue the use of Sumatriptan and Naproxen Sodium Tablets at the first appearance of skin rash or any other sign of hypersensitivity. Sumatriptan and Naproxen Sodium Tablets is contraindicated in patients with previous serious skin reactions to NSAIDs [see Contraindications (4)].
^ Renal Impairment
Sumatriptan and Naproxen Sodium Tablets is not recommended for use in patients with creatinine clearance less than 30 mL/min. Monitor the serum creatinine or creatinine clearance in patients with mild (CrCl = 60 to 89 mL/min) or moderate (CrCL = 30 to 59 mL/min) renal impairment, preexisting kidney disease, or dehydration [see Warnings and Precautions (5.12) and Clinical Pharmacology (12.3)].
^3 Dosage Forms And Strengths
10 mg sumatriptan/60 mg naproxen sodium, light-blue film-coated tablets, debossed on one side with "TREXIMET" and the other side with "10-60".
85 mg sumatriptan/500 mg naproxen sodium, blue film-coated tablets, debossed on one side with "TREXIMET".
^ Exacerbation Of Asthma Related To Aspirin Sensitivity
A subpopulation of patients with asthma may have aspirin-sensitive asthma which may include chronic rhinosinusitis complicated by nasal polyps; severe, potentially fatal bronchospasm; and/or intolerance to aspirin and other NSAIDs. Because cross-reactivity between aspirin and other NSAIDs has been reported in such aspirin-sensitive patients, Sumatriptan and Naproxen Sodium Tablets is contraindicated in patients with this form of aspirin sensitivity and should be used with caution in patients with preexisting asthma [see Contraindications (4)].
When Sumatriptan and Naproxen Sodium Tablets is used in patients with preexisting asthma (without known aspirin sensitivity), monitor patients for changes in the signs and symptoms of asthma.
^ Hypertension
Significant elevation in blood pressure, including hypertensive crisis with acute impairment of organ systems, has been reported on rare occasions in patients treated with 5-HT1 agonists, including sumatriptan, a component of Sumatriptan and Naproxen Sodium Tablets. This occurrence has included patients without a history of hypertension.
NSAIDs, including naproxen, a component of Sumatriptan and Naproxen Sodium Tablets, can also lead to onset of new hypertension or worsening of preexisting hypertension, either of which may contribute to the increased incidence of cardiovascular events. Patients taking angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), beta-blockers, thiazide diuretics, or loop diuretics may have impaired response to these therapies when taking NSAIDs [see Drug Interactions (7)].
Monitor blood pressure in patients treated with Sumatriptan and Naproxen Sodium Tablets. Sumatriptan and Naproxen Sodium Tablets is contraindicated in patients with uncontrolled hypertension [see Contraindications (4)].

^ Pediatric Use
Safety and effectiveness of Sumatriptan and Naproxen Sodium Tablets in pediatric patients under 12 years of age have not been established.
The safety and efficacy of Sumatriptan and Naproxen Sodium Tablets for the acute treatment of migraine in pediatric patients 12 to 17 years of age was established in a double-blind, placebo-controlled trial [see Adverse Reactions (6.1) and Clinical Studies (14.2)].
^ Serotonin Syndrome
Serotonin syndrome may occur with Sumatriptan and Naproxen Sodium Tablets, particularly during coadministration with selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), and MAO inhibitors [see Contraindications (4) and Drug Interactions (7.1)]. Serotonin syndrome symptoms may include mental status changes (e.g., agitation, hallucinations, coma), autonomic instability (e.g., tachycardia, labile blood pressure, hyperthermia), neuromuscular aberrations (e.g., hyperreflexia, incoordination), and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). The onset of symptoms usually occurs within minutes to hours of receiving a new or a greater dose of a serotonergic medication. Discontinue Sumatriptan and Naproxen Sodium Tablets if serotonin syndrome is suspected.
^ Administration Information
Sumatriptan and Naproxen Sodium Tablets may be administered with or without food. Tablets should not be split, crushed, or chewed.
^4 Contraindications
Sumatriptan and Naproxen Sodium Tablets is contraindicated in the following patients:
^ Postmarketing Experience
The following adverse reactions have been identified during post-approval use of NSAIDs, such as naproxen, which is a component of Sumatriptan and Naproxen Sodium Tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Skin and Appendages: exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), toxic epidermal necrolysis (TEN), and fixed drug eruption (FDE) [see Warnings and Precautions (5.14) ].
^ How Supplied/storage And Handling
Sumatriptan and Naproxen Sodium Tablets 85/500 mg contains 119 mg of sumatriptan succinate equivalent to 85 mg of sumatriptan and 500 mg of naproxen sodium and is supplied as blue film-coated tablets debossed on one side with TREXIMET in bottles of 9 tablets with desiccant (NDC 44183-850-09).
Sumatriptan and Naproxen Sodium Tablets 10/60 mg contains 14 mg of sumatriptan succinate equivalent to 10 mg of sumatriptan and 60 mg of naproxen sodium and is supplied as light-blue film-coated tablets debossed on one side with TREXIMET and the other side with 10-60 in bottles of 9 tablets with desiccant (NDC 44183-860-09).
^ Geriatric Use
Elderly patients, compared to younger patients, are at greater risk for NSAID-associated serious cardiovascular, gastrointestinal, and/or renal adverse reactions. Sumatriptan and Naproxen Sodium Tablets is not recommended for use in elderly patients who have decreased renal function, higher risk for unrecognized CAD, and increases in blood pressure that may be more pronounced in the elderly [see Warnings and Precautions (5.1, 5.2, 5.3, 5.8, 5.12) and Clinical Pharmacology (12.3)].
A cardiovascular evaluation is recommended for geriatric patients who have other cardiovascular risk factors (e.g., diabetes, hypertension, smoking, obesity, strong family history of CAD) prior to receiving Sumatriptan and Naproxen Sodium Tablets [see Warnings and Precautions (5.1)].
^ Dosage In Adults
The recommended dosage for adults is 1 tablet of Sumatriptan and Naproxen Sodium Tablets 85/500 mg. Sumatriptan and Naproxen Sodium Tablets 85/500 mg contains a dose of sumatriptan higher than the lowest effective dose. The choice of the dose of sumatriptan, and of the use of a fixed combination such as in Sumatriptan and Naproxen Sodium Tablets 85/500 mg should be made on an individual basis, weighing the possible benefit of a higher dose of sumatriptan with the potential for a greater risk of adverse reactions.
The maximum recommended dosage in a 24-hour period is 2 tablets, taken at least 2 hours apart.
The safety of treating an average of more than 5 migraine headaches in adults in a 30-day period has not been established.
Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and Precautions (5)].
^ Other Vasospasm Reactions
Sumatriptan may cause non-coronary vasospastic reactions, such as peripheral vascular ischemia, gastrointestinal vascular ischemia and infarction (presenting with abdominal pain and bloody diarrhea), splenic infarction, and Raynaud's syndrome. In patients who experience symptoms or signs suggestive of non-coronary vasospasm reaction following the use of any 5-HT1 agonist, rule out a vasospastic reaction before receiving additional Sumatriptan and Naproxen Sodium Tablets.
Reports of transient and permanent blindness and significant partial vision loss have been reported with the use of 5-HT1 agonists. Since visual disorders may be part of a migraine attack, a causal relationship between these events and the use of 5-HT1 agonists have not been clearly established.
^ Hematologic Toxicity
Anemia has occurred in patients receiving NSAIDs. This may be due to fluid retention, occult or gross gastrointestinal blood loss, or an incompletely described effect upon erythropoiesis. If a patient treated with Sumatriptan and Naproxen Sodium Tablets has signs or symptoms of anemia, monitor hemoglobin or hematocrit.
NSAIDs, including Sumatriptan and Naproxen Sodium Tablets, may increase the risk of bleeding events. Co-morbid conditions such as coagulation disorders or concomitant use of warfarin, other anticoagulants, antiplatelet agents (e.g., aspirin), serotonin reuptake inhibitors (SSRIs), and serotonin norepinephrine reuptake inhibitors (SNRIs) may increase this risk. Monitor these patients for signs of bleeding [see Drug Interactions (7)].
^ Adults
The efficacy of Sumatriptan and Naproxen Sodium Tablets in the acute treatment of migraine with or without aura in adults was demonstrated in 2 randomized, double-blind, multicenter, parallel-group trials utilizing placebo and each individual active component of Sumatriptan and Naproxen Sodium Tablets 85/500 mg (sumatriptan and naproxen sodium) as comparison treatments (Study 1 and Study 2). Patients enrolled in these 2 trials were predominately female (87%) and white (88%), with a mean age of 40 years (range: 18 to 65 years). Patients were instructed to treat a migraine of moderate to severe pain with 1 tablet. No rescue medication was allowed within 2 hours postdose. Patients evaluated their headache pain 2 hours after taking 1 dose of study medication; headache relief was defined as a reduction in headache severity from moderate or severe pain to mild or no pain. Associated symptoms of nausea, photophobia, and phonophobia were also evaluated. Sustained pain free was defined as a reduction in headache severity from moderate or severe pain to no pain at 2 hours postdose without a return of mild, moderate, or severe pain and no use of rescue medication for 24 hours postdose. The results from Study 1 and 2 are summarized in Table 4. In both trials, the percentage of patients achieving headache pain relief 2 hours after treatment was significantly greater among patients receiving Sumatriptan and Naproxen Sodium Tablets 85/500 mg (65% and 57%) compared with those who received placebo (28% and 29%).
Further, the percentage of patients who remained pain free without use of other medications through 24 hours postdose was significantly greater among patients receiving a single dose of Sumatriptan and Naproxen Sodium Tablets 85/500 mg (25% and 23%) compared with those who received placebo (8% and 7%) or either sumatriptan (16% and 14%) or naproxen sodium (10%) alone.
The percentage of patients achieving initial headache pain relief within 2 hours following treatment with Sumatriptan and Naproxen Sodium Tablets 85/500 mg is shown in Figure 1.
Figure 1. Percentage of Adult Patients with Initial Headache Pain Relief within 2 Hours
Compared with placebo, there was a decreased incidence of photophobia, phonophobia, and nausea 2 hours after the administration of Sumatriptan and Naproxen Sodium Tablets 85/500 mg. The estimated probability of taking a rescue medication over the first 24 hours is shown in Figure 2.
Figure 2. Estimated Probability of Adults Taking a Rescue Medication over the 24 Hours following the First DoseKaplan-Meier plot based on data obtained in the 2 clinical controlled trials providing evidence of efficacy with patients not using additional treatments censored to 24 hours. Plot also includes patients who had no response to the initial dose. No rescue medication was allowed within 2 hours postdose.
Sumatriptan and Naproxen Sodium Tablets 85/500 mg was more effective than placebo regardless of the presence of aura; duration of headache prior to treatment; gender, age, or weight of the subject; or concomitant use of oral contraceptives or common migraine prophylactic drugs (e.g., beta-blockers, anti-epileptic drugs, tricyclic antidepressants).
^ Arrhythmias
Life-threatening disturbances of cardiac rhythm, including ventricular tachycardia and ventricular fibrillation leading to death, have been reported within a few hours following the administration of 5-HT1 agonists. Discontinue Sumatriptan and Naproxen Sodium Tablets if these disturbances occur. Sumatriptan and Naproxen Sodium Tablets is contraindicated in patients with Wolff-Parkinson-White syndrome or arrhythmias associated with other cardiac accessory conduction pathway disorders.
^ Hepatotoxicity
Borderline elevations of 1 or more liver tests may occur in up to 15% of patients who take NSAIDs including naproxen, a component of Sumatriptan and Naproxen Sodium Tablets. Hepatic abnormalities may be the result of hypersensitivity rather than direct toxicity. These abnormalities may progress, may remain essentially unchanged, or may be transient with continued therapy. Notable (3 times the upper limit of normal) elevations of SGPT (ALT) or SGOT (AST) have been reported in approximately 1% of patients in clinical trials with NSAIDs. In addition, rare, sometimes fatal cases of severe hepatic injury, including jaundice and fatal fulminant hepatitis, liver necrosis, and hepatic failure have been reported with NSAIDs.
Sumatriptan and Naproxen Sodium Tablets is contraindicated in patients with severe hepatic impairment [see Use in Specific Populations (8.7), Clinical Pharmacology (12.3)]. A patient with symptoms and/or signs suggesting liver dysfunction, or in whom an abnormal liver test has occurred, should be evaluated for evidence of the development of a more severe hepatic reaction while on therapy with Sumatriptan and Naproxen Sodium Tablets. Sumatriptan and Naproxen Sodium Tablets should be discontinued if clinical signs and symptoms consistent with liver disease develop, if systemic manifestations occur (e.g., eosinophilia, rash), or if abnormal liver tests persist or worsen.
Inform patients of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, diarrhea, pruritus, jaundice, right upper quadrant tenderness, and "flulike" symptoms). If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (e.g., eosinophilia, rash, etc.), discontinue Sumatriptan and Naproxen Sodium Tablets immediately, and perform a clinical evaluation of the patient.
^ Anaphylactic Reactions
Anaphylactic reactions may occur in patients without known prior exposure to either component of Sumatriptan and Naproxen Sodium Tablets. Such reactions can be life-threatening or fatal. In general, anaphylactic reactions to drugs are more likely to occur in individuals with a history of sensitivity to multiple allergens although anaphylactic reactions with naproxen have occurred in patient without known hypersensitivity to naproxen or to patients with aspirin sensitive asthma [see Contraindications (4) and Warnings and Precautions (5.18)]. Sumatriptan and Naproxen Sodium Tablets should not be given to patients with the aspirin triad. This symptom complex typically occurs in patients with asthma who experience rhinitis with or without nasal polyps, or who exhibit severe, potentially fatal bronchospasm after taking aspirin or other NSAIDs [see Contraindications (4)].
Sumatriptan and Naproxen Sodium Tablets is contraindicated in patients with a history of hypersensitivity reaction to sumatriptan, naproxen, or any other component of Sumatriptan and Naproxen Sodium Tablets. Naproxen has been associated with anaphylactic reactions in patients without known hypersensitivity to naproxen and in patients with aspirin-sensitive asthma [see Contraindications (4) and Warnings and Precautions (5.18)]. Seek emergency help if an anaphylactic reaction occurs.
^6 Adverse Reactions
The following serious adverse reactions are described below and elsewhere in labeling:
^ Dosage In Pediatric Patients To Years Of Age
The recommended dosage for pediatric patients 12 to 17 years of age is 1 tablet of Sumatriptan and Naproxen Sodium Tablets 10/60 mg.
The maximum recommended dosage in a 24-hour period is 1 tablet of Sumatriptan and Naproxen Sodium Tablets 85/500 mg.
The safety of treating an average of more than 2 migraine headaches in pediatric patients in a 30-day period has not been established.
Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and Precautions (5)].
^ Clinically Significant Drug Interactions With Sumatriptan And Naproxen Sodium Tablets
See Table 3 for clinically significant drug interactions with NSAIDs or Sumatriptan.
^ Cerebrovascular Events
Cerebral hemorrhage, subarachnoid hemorrhage, and stroke have occurred in patients treated with 5-HT1 agonists, and some have resulted in fatalities. In a number of cases, it appears possible that the cerebrovascular events were primary, the 5-HT1 agonist having been administered in the incorrect belief that the symptoms experienced were a consequence of migraine when they were not. Also, patients with migraine may be at increased risk of certain cerebrovascular events (e.g., stroke, hemorrhage, TIA). Discontinue Sumatriptan and Naproxen Sodium Tablets if a cerebrovascular event occurs.
Before treating headaches in patients not previously diagnosed as migraineurs, and in migraineurs who present with atypical symptoms, exclude other potentially serious neurological conditions. Sumatriptan and Naproxen Sodium Tablets is contraindicated in patients with a history of stroke or TIA [see Contraindications (4)].
^ Cardiovascular Thrombotic Events
The use of Sumatriptan and Naproxen Sodium Tablets is contraindicated in patients with ischemic or vasospastic coronary artery disease (CAD) and in the setting of coronary artery bypass graft (CABG) surgery due to increased risk of serious cardiovascular events with sumatriptan and NSAIDS [see Contraindications (4)].
^1 Indications And Usage
Sumatriptan and Naproxen Sodium Tablets is indicated for the acute treatment of migraine with or without aura in adults and pediatric patients 12 years of age and older.
^ Laboratory Monitoring
Because serious GI bleeding, hepatotoxicity, and renal injury can occur without warning symptoms or signs, consider monitoring patients on long-term NSAID treatment with a CBC and a chemistry profile periodically [see Warnings and Precautions (5.2, 5.7, 5.12)].
^ Masking Of Inflammation And Fever
The pharmacological activity of Sumatriptan and Naproxen Sodium Tablets in reducing inflammation, and possibly fever, may diminish the utility of diagnostic signs in detecting infections.
^ Mechanism Of Action
Sumatriptan and Naproxen Sodium Tablets contains sumatriptan and naproxen.
Sumatriptan binds with high affinity to cloned 5-HT1B/1D receptors. Sumatriptan presumably exerts its therapeutic effects in the treatment of migraine headache through agonist effects at the 5-HT1B/1D receptors on intracranial blood vessels and sensory nerves of the trigeminal system, which result in cranial vessel constriction and inhibition of neuropeptide release.
Sumatriptan and Naproxen Sodium Tablets has analgesic, anti-inflammatory, and antipyretic properties. The mechanism of action of Sumatriptan and Naproxen Sodium Tablets, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2).
Naproxen is a potent inhibitor of prostaglandin synthesis in vitro. Naproxen concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in animal models. Prostaglandins are mediators of inflammation. Because naproxen is an inhibitor of prostaglandin synthesis, its mode of action may be due to a decrease of prostaglandins in peripheral tissues.
^ Heart Failure And Edema
The Coxib and traditional NSAID Trialists' Collaboration meta-analysis of randomized controlled trials demonstrated an approximately two-fold increase in hospitalizations for heart failure in COX-2 selective-treated patients and nonselective NSAID-treated patients compared to placebo-treated patients. In a Danish National Registry study of patients with heart failure, NSAID use increased the risk of MI, hospitalization for heart failure, and death.
Additionally, fluid retention and edema have been observed in some patients treated with NSAIDs. Use of naproxen may blunt the CV effects of several therapeutic agents used to treat these medical conditions (e.g., diuretics, ACE inhibitors, or angiotensin receptor blockers [ARBs]) [see Drug Interactions (7)].
Avoid the use of Sumatriptan and Naproxen Sodium Tablets in patients with severe heart failure unless the benefits are expected to outweigh the risk of worsening heart failure. If Sumatriptan and Naproxen Sodium Tablets is used in patients with severe heart failure, monitor patients for signs of worsening heart failure.
Since each Sumatriptan and Naproxen Sodium Tablets 85/500 mg tablet contains approximately 60 mg of sodium and each Sumatriptan and Naproxen Sodium Tablets 10/60 mg tablet contains approximately 20 mg of sodium, this should be considered in patients whose overall intake of sodium must be severely restricted.
^ Chest, Throat, Neck, And/or Jaw Pain/tightness/pressure
Sensations of tightness, pain, pressure, and heaviness in the precordium, throat, neck, and jaw commonly occur after treatment with sumatriptan and are usually non-cardiac in origin. However, perform a cardiac evaluation if these patients are at high cardiac risk. The use of Sumatriptan and Naproxen Sodium Tablets is contraindicated in patients with CAD and those with Prinzmetal's variant angina.
