7.3 Selective Serotonin Reuptake Inhibitors/Serotonin and Norepinephrine Reuptake Inhibitors and Serotonin Syndrome
Eletriptan is indicated for the acute treatment of migraine with or without aura in adults.
Limitations of Use:
The maximum recommended single dose is 40 mg.
In controlled clinical trials, single doses of 20 mg and 40 mg were effective for the acute treatment of migraine in adults. A greater proportion of patients had a response following a 40 mg dose than following a 20 mg dose [see Clinical Studies (14)].
If the migraine has not resolved by 2 hours after taking eletriptan, or returns after transient improvement, a second dose may be administered at least 2 hours after the first dose. The maximum daily dose should not exceed 80 mg.
The safety of treating an average of more than 3 migraine attacks in a 30-day period has not been established.
20 mg Tablets: Orange, round, convex shaped, film-coated, with "PFIZER" and "REP20" debossed.
40 mg Tablets: Orange, round, convex shaped, film-coated, with "PFIZER" and "REP40" debossed.
Eletriptan is contraindicated in patients with:
Eletriptan should only be used where a clear diagnosis of migraine has been established.
Eletriptan is contraindicated in patients with ischemic or vasospastic CAD. There have been rare reports of serious cardiac adverse reactions, including acute myocardial infarction, occurring within a few hours following administration of eletriptan. Some of these reactions occurred in patients without known CAD. Eletriptan may cause coronary artery vasospasm (Prinzmetal's angina), even in patients without a history of CAD.
Perform a cardiovascular evaluation in triptan-naïve patients who have multiple cardiovascular risk factors (e.g., increased age, diabetes, hypertension, smoking, obesity, strong family history of CAD) prior to receiving eletriptan. Do not use eletriptan if there is evidence of CAD or coronary artery vasospasm [see Contraindications (4)]. For patients with multiple cardiovascular risk factors who have a negative cardiovascular evaluation, consider administering the first eletriptan dose in a medically-supervised setting and performing an electrocardiogram (ECG) immediately following administration of eletriptan. For such patients, consider periodic cardiovascular evaluation in intermittent long-term users of eletriptan.
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 eletriptan if these disturbances occur. Eletriptan is contraindicated in patients with Wolff-Parkinson-White syndrome or arrhythmias associated with other cardiac accessory conduction pathway disorders [see Contraindications (4)].
Sensations of tightness, pain, and pressure in the chest, throat, neck, and jaw commonly occur after treatment with eletriptan and are usually non-cardiac in origin. However, perform a cardiac evaluation if these patients are at high cardiac risk. Eletriptan is contraindicated in patients with CAD or Prinzmetal's variant angina [see Contraindications (4)].
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.
Before treating headaches in patients not previously diagnosed as migraineurs, and in migraineurs who present with symptoms atypical of migraine, other potentially serious neurological conditions need to be excluded. Eletriptan is contraindicated in patients with a history of stroke or TIA [see Contraindications (4)].
Eletriptan may cause non-coronary vasospastic reactions, such as peripheral vascular ischemia, gastrointestinal vascular ischemia and infarction (presenting with abdominal pain and bloody diarrhea), and Raynaud's syndrome. In patients who experience symptoms or signs suggestive of a vasospastic reaction following the use of any 5-HT1 agonist, rule out a vasospastic reaction before receiving additional eletriptan doses [see Contraindications (4)].
Overuse of acute migraine drugs (e.g. ergotamine, triptans, opioids, or 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 acute migraine drugs and treatment of withdrawal symptoms (which often includes a transient worsening of headache) may be necessary.
Serotonin syndrome may occur with eletriptan, particularly during co-administration with selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), and monoamine oxidase (MAO) inhibitors [see Drug Interactions (7.3)]. 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 eletriptan if serotonin syndrome is suspected.
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 patients without a history of hypertension. Monitor blood pressure in patients treated with eletriptan. Eletriptan is contraindicated in patients with uncontrolled hypertension [see Contraindications (4)].
There have been reports of anaphylaxis, anaphylactoid, and hypersensitivity reactions including angioedema in patients receiving eletriptan. 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. Eletriptan is contraindicated in patients with a history of hypersensitivity reaction to eletriptan [see Contraindications (4)].
The following adverse reactions are described elsewhere in other sections of the prescribing information:
Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice.
Among 4,597 patients who treated the first migraine headache with eletriptan in short-term placebo-controlled trials, the most common adverse reactions reported with treatment with eletriptan were asthenia, nausea, dizziness, and somnolence. These reactions appear to be dose-related.
In long-term open-label studies where patients were allowed to treat multiple migraine attacks for up to 1 year, 128 (8.3%) out of 1,544 patients discontinued treatment due to adverse reactions.
Table 1 lists adverse reactions that occurred in the subset of 5,125 migraineurs who received eletriptan doses of 20 mg, 40 mg and 80 mg or placebo in worldwide placebo-controlled clinical trials.
Only adverse reactions that were more frequent in an eletriptan treatment group compared to the placebo group with an incidence greater than or equal to 2% are included in Table 1.
|Adverse Reaction Type||Placebo|
|Flushing/feeling of warmth||2%||2%||2%||2%|
|PAIN AND PRESSURE SENSATIONS|
|Chest – tightness/pain/pressure||1%||1%||2%||4%|
|Abdominal – pain/discomfort/stomach pain/ cramps/pressure||1%||1%||2%||2%|
|Dysphagia – throat tightness/difficulty swallowing||0.2%||1%||2%||2%|
The frequency of adverse reactions in clinical trials did not increase when up to 2 doses of eletriptan were taken within 24 hours. The incidence of adverse reactions in controlled clinical trials was not affected by gender, age, or race of the patients. Adverse reaction frequencies were also unchanged by concomitant use of drugs commonly taken for migraine prophylaxis (e.g., SSRIs, beta blockers, calcium channel blockers, tricyclic antidepressants), estrogen replacement therapy or oral contraceptives.
The following adverse reaction(s) have been identified during post approval use of eletriptan. 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.
Ergot-containing drugs have been reported to cause prolonged vasospastic reactions. Because these effects may be additive, use of ergotamine-containing or ergot-type medications (like dihydroergotamine [DHE] or methysergide) and eletriptan within 24 hours of each other is contraindicated. Concomitant use of other 5-HT1 agonists within 24 hours of eletriptan treatment is contraindicated [see Contraindications (4)].
Potent CYP3A4 inhibitors significantly increase the exposure of eletriptan. Eletriptan should not be used within at least 72 hours of treatment with potent CYP3A4 inhibitors [see Contraindications (4) and Clinical Pharmacology (12.3)].
Cases of serotonin syndrome have been reported during co-administration of triptans and SSRIs, SNRIs, TCAs and MAO inhibitors [see Warnings and Precautions (5.7)].
Pregnancy Category C: There are no adequate and well-controlled studies in pregnant women. In reproductive toxicity studies in pregnant animals, oral administration of eletriptan was associated with developmental toxicity (decreased fetal and pup weights and an increased incidence of fetal structural abnormalities) at clinically relevant plasma exposures. Eletriptan should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus
When pregnant rats were administered eletriptan during the period of organogenesis at doses of 10, 30 or 100 mg/kg/day, fetal weights were decreased and the incidences of vertebral and sternebral variations were increased at 100 mg/kg/day (approximately 12 times the maximum recommended human dose [MRHD] of 80 mg/day on a mg/m2 basis). The 30 and 100 mg/kg/day doses were also maternally toxic, as evidenced by decreased maternal body weight gain during gestation. The no-effect dose for developmental toxicity in rats was 30 mg/kg/day, which is approximately 4 times the MRHD on a mg/m2 basis.
When doses of 5, 10, or 50 mg/kg/day were given to pregnant rabbits throughout organogenesis, fetal weights were decreased at 50 mg/kg/day, which is approximately 12 times the MRHD on a mg/m2 basis. The incidences of fused sternebrae and vena cava deviations were increased at all doses. Maternal toxicity was not evident at any dose. A no-effect dose for developmental toxicity in rabbits was not established; the lowest dose tested (5 mg/kg/day) is similar to the MRHD on a mg/m2 basis.
Eletriptan is excreted in human milk. Caution should be exercised when eletriptan is administered to a nursing woman.
Safety and effectiveness in pediatric patients have not been established.
The efficacy of eletriptan tablets (40 mg) in patients 11–17 was not established in a randomized, placebo-controlled trial of 274 adolescent migraineurs [see Clinical Studies (14)]. Adverse reactions observed were similar in nature to those reported in clinical trials in adults. Postmarketing experience with other triptans includes a limited number of reports that describe pediatric patients who have experienced clinically serious adverse reactions that are similar in nature to those reported rarely in adults. Long-term safety of eletriptan was studied in 76 adolescent patients who received treatment for up to one year. A similar profile of adverse reactions to that of adults was observed. The long-term safety of eletriptan in pediatric patients has not been established.
Blood pressure was increased to a greater extent in elderly subjects than in young subjects. The pharmacokinetic disposition of eletriptan in the elderly is similar to that seen in younger adults [see Clinical Pharmacology (12.3)]. In clinical trials, there were no apparent differences in efficacy or the incidence of adverse reactions between patients under 65 years of age and those 65 and above.
The effect of severe hepatic impairment on eletriptan metabolism has not been evaluated. Eletriptan is not recommended for use in patients with severe hepatic impairment [see Clinical Pharmacology (12.3)].
The elimination half-life of eletriptan is about 4 hours [see Clinical Pharmacology (12.3)], therefore monitoring of patients after overdose with eletriptan should continue for at least 20 hours or longer while symptoms or signs persist.
There is no specific antidote to eletriptan.
It is unknown what effect hemodialysis or peritoneal dialysis has on the serum concentration of eletriptan.
Eletriptan tablets contain eletriptan hydrobromide, which is a selective 5-hydroxytryptamine 1B/1D (5-HT1B/1D) receptor agonist. Eletriptan hydrobromide is chemically designated as (R)-3-[(1-Methyl-2-pyrrolidinyl)methyl]-5-[2-(phenylsulfonyl)ethyl]-1H-indole monohydrobromide, and it has the following chemical structure:
The empirical formula is C22H26N2O2S . HBr, representing a molecular weight of 463.43. Eletriptan hydrobromide is a white to light pale colored powder that is readily soluble in water.
Each eletriptan tablet for oral administration contains 24.2 or 48.5 mg of eletriptan hydrobromide equivalent to 20 mg or 40 mg of eletriptan, respectively. Each tablet also contains the inactive ingredients microcrystalline cellulose NF, lactose monohydrate NF, croscarmellose sodium NF, magnesium stearate NF, titanium dioxide USP, hypromellose, triacetin USP and FD&C Yellow No. 6 aluminum lake.
Eletriptan binds with high affinity to 5-HT1B, 5-HT1D and 5-HT1F receptors, has modest affinity for 5-HT1A, 5-HT1E, 5-HT2B and 5-HT7 receptors.
Migraines are likely due to local cranial vasodilatation and/or to the release of sensory neuropeptides (vasoactive intestinal peptide, substance P and calcitonin gene-related peptide) through nerve endings in the trigeminal system. The therapeutic activity of eletriptan for the treatment of migraine headache is thought to be due to the agonist effects at the 5-HT1B/1D receptors on intracranial blood vessels (including the arterio-venous anastomoses) and sensory nerves of the trigeminal system which result in cranial vessel constriction and inhibition of pro-inflammatory neuropeptide release.
Absorption: Eletriptan is well absorbed after oral administration with peak plasma levels occurring approximately 1.5 hours after dosing to healthy subjects. In patients with moderate to severe migraine the median Tmax is 2.0 hours. The mean absolute bioavailability of eletriptan is approximately 50%. The oral pharmacokinetics are slightly more than dose-proportional over the clinical dose range. The AUC and Cmax of eletriptan are increased by approximately 20 to 30% following oral administration with a high fat meal. Eletriptan can be taken with or without food.
Distribution: The volume of distribution of eletriptan following IV administration is 138L. Plasma protein binding is moderate and approximately 85%.
Metabolism: The N-demethylated metabolite of eletriptan is the only known active metabolite. This metabolite causes vasoconstriction similar to eletriptan in animal models. Though the half-life of the metabolite is estimated to be about 13 hours, the plasma concentration of the N-demethylated metabolite is 10–20% of parent drug and is unlikely to contribute significantly to the overall effect of the parent compound.
Elimination: The terminal elimination half-life of eletriptan is approximately 4 hours. Mean renal clearance (CLR) following oral administration is approximately 3.9 L/h. Non-renal clearance accounts for about 90% of the total clearance.
Age: The pharmacokinetics of eletriptan are generally unaffected by age. Blood pressure was increased to a greater extent in elderly subjects than in young subjects [see Use in Specific Populations (8.5)]. The pharmacokinetic disposition of eletriptan in the elderly is similar to that seen in younger adults.
There is a statistically significant increased half-life (from about 4.4 hours to 5.7 hours) between elderly (65 to 93 years of age) and younger adult subjects (18 to 45 years of age) [see Use in Specific Populations (8.5)].
Race: A comparison of pharmacokinetic studies run in western countries with those run in Japan has indicated an approximate 35% reduction in the exposure of eletriptan in Japanese male volunteers compared to western males. Population pharmacokinetic analysis of two clinical studies indicates no evidence of pharmacokinetic differences between Caucasians and non-Caucasian patients.
Menstrual Cycle: In a study of 16 healthy females, the pharmacokinetics of eletriptan remained consistent throughout the phases of the menstrual cycle.
Renal Impairment: There was no significant change in clearance observed in subjects with mild, moderate or severe renal impairment, though blood pressure elevations were observed in this population [see Warnings and Precautions (5.8)].
Hepatic Impairment: Subjects with mild or moderate hepatic impairment demonstrated an increase in both AUC (34%) and half-life. The Cmax was increased by 18%. No dose adjustment is necessary in subjects with mild or moderate hepatic impairment. The effects of severe hepatic impairment on eletriptan metabolism have not been evaluated [see Use in Specific Populations (8.6)].
Drug Interaction Studies
CYP3A4 inhibitors: In vitro studies have shown that eletriptan is metabolized by the CYP3A4 enzyme. A clinical study demonstrated about a 3-fold increase in Cmax and about a 6-fold increase in the AUC of eletriptan when combined with ketoconazole. The half-life increased from 5 hours to 8 hours and the Tmax increased from 2.8 hours to 5.4 hours. Another clinical study demonstrated about a 2-fold increase in Cmax and about a 4-fold increase in AUC when erythromycin was co-administered with eletriptan. It has also been shown that co-administration of verapamil and eletriptan yields about a 2-fold increase in Cmax and about a 3-fold increase in AUC of eletriptan, and that co-administration of fluconazole and eletriptan yields about a 1.4-fold increase in Cmax and about a 2-fold increase in AUC of eletriptan.
Eletriptan is contraindicated within at least 72 hours of treatment with the following potent CYP3A4 inhibitors: ketoconazole, itraconazole, nefazodone, troleandomycin, clarithromycin, ritonavir and nelfinavir. Eletriptan should not be used within 72 hours with drugs that have demonstrated potent CYP3A4 inhibition [see Contraindications (4)].
Propranolol: The Cmax and AUC of eletriptan were increased by 10 and 33%, respectively, in the presence of propranolol. No interactive increases in blood pressure were observed. No dosage adjustment appears to be needed for patients taking propranolol.
The effect of eletriptan on other drugs: The effect of eletriptan on enzymes other than cytochrome P450 has not been investigated. In vitro human liver microsome studies suggest that eletriptan has little potential to inhibit CYP1A2, 2C9, 2E1 and 3A4 at concentrations up to 100 µM. While eletriptan has an effect on CYP2D6 at high concentration, this effect should not interfere with metabolism of other drugs when eletriptan is used at recommended doses. There is no in vitro or in vivo evidence that clinical doses of eletriptan will induce drug metabolizing enzymes. Therefore, eletriptan is unlikely to cause clinically important drug interactions mediated by these enzymes.
Eletriptan was administered to rats and mice in the diet for 104 weeks. In rats, the incidence of testicular interstitial cell adenomas was increased at the high dose of 75 mg/kg/day, but not at 15 mg/kg/day, a dose associated with plasma exposures (AUC) approximately 2 times that in humans at the MRHD of 80 mg/day. In mice, the incidence of hepatocellular adenomas was increased at the high dose of 400 mg/kg/day, but not a dose of 90 mg/kg/day, associated with plasma AUC approximately 7 times that in humans at the MRHD.
Eletriptan was negative in in vitro (bacteria reverse mutation (Ames), mammalian cell gene mutation (CHO/ HGPRT), chromosomal aberration assay in human lymphocytes) and in vivo (mouse micronucleus) assays.
Impairment of Fertility
In a fertility and early embryonic development study, eletriptan (50, 100, or 200 mg/kg/day) was orally administered to male and female rats prior to and throughout mating and continuing in females to implantation. Plasma exposures (AUC) were 4, 8 and 16 times in males and 7, 14 and 28 times in females, respectively, that in humans at the MRHD. Dose-related decreases in the number of corpora lutea, implants, and viable fetuses per dam were observed at all doses. Prolongation of the estrus cycle was observed at the highest dose tested. Male fertility parameters were not affected.
The efficacy of eletriptan in the acute treatment of migraines was evaluated in eight randomized, double-blind placebo-controlled studies. All eight studies used 40 mg. Seven studies evaluated an 80 mg dose and two studies included a 20 mg dose.
In all eight studies, randomized patients treated their headaches as outpatients. Seven studies enrolled adults and one study enrolled adolescents (age 11 to 17). Patients treated in the seven adult studies were predominantly female (85%) and Caucasian (94%) with a mean age of 40 years (range 18 to 78). In all studies, patients were instructed to treat a moderate to severe headache. Headache response, defined as a reduction in headache severity from moderate or severe pain to mild or no pain, was assessed up to 2 hours after dosing. Associated symptoms such as nausea, vomiting, photophobia and phonophobia were also assessed.
Maintenance of response was assessed for up to 24 hours post dose. In the adult studies, a second dose of eletriptan or other medication was allowed 2 to 24 hours after the initial treatment for both persistent and recurrent headaches. The incidence and time to use of these additional treatments were also recorded.
In the seven adult studies, the percentage of patients achieving headache response 2 hours after treatment was significantly greater among patients receiving eletriptan at all doses compared to those who received placebo. The two-hour response rates from these controlled clinical studies are summarized in Table 2.
|NA - Not Applicable|
Comparisons of the performance of different drugs based upon results obtained in different clinical trials are never reliable. Because studies are generally conducted at different times, with different samples of patients, by different investigators, employing different criteria and/or different interpretations of the same criteria, under different conditions (dose, dosing regimen, etc.), quantitative estimates of treatment response and the timing of response may be expected to vary considerably from study to study.
The estimated probability of achieving an initial headache response within 2 hours following treatment is depicted in Figure 1.
|Figure 1: Estimated Probability of Initial Headache Response Within 2 Hours*|
For patients with migraine-associated photophobia, phonophobia, and nausea at baseline, there was a decreased incidence of these symptoms following administration of eletriptan as compared to placebo.
Two to 24 hours following the initial dose of study treatment, patients were allowed to use additional treatment for pain relief in the form of a second dose of study treatment or other medication. The estimated probability of taking a second dose or other medications for migraine over the 24 hours following the initial dose of study treatment is summarized in Figure 2.
|Figure 2: Estimated Probability of Taking a Second Dose/Other Medication Over the 24 Hours Following the First Dose*|
The efficacy of eletriptan was unaffected by the duration of attack, gender or age of the patient, relationship to menses, or concomitant use of estrogen replacement therapy/oral contraceptives or frequently used migraine prophylactic drugs.
In a single study in adolescents (n=274), there were no statistically significant differences between treatment groups. The headache response rate at 2 hours was 57% for both eletriptan 40 mg Tablets and placebo.

Myocardial Ischemia and/or Infarction, Prinzmetal's Angina, Other Vasospastic Reactions, and Cerebrovascular Events
Inform patients that eletriptan may cause serious cardiovascular adverse reactions such as myocardial infarction or stroke, which may result in hospitalization and even death. Although serious cardiovascular reactions can occur without warning symptoms, instruct patients to be alert for the signs and symptoms of chest pain, shortness of breath, weakness, slurring of speech, and instruct them to ask for medical advice when observing any indicative sign or symptoms. Instruct patients to seek medical advice if they have symptoms of other vasospastic reactions [see Warnings and Precautions (5.1, 5.2, 5.4, 5.5, and 5.8)].
Inform patients that anaphylactic/anaphylactoid reactions have occurred in patients receiving eletriptan. 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 [see Contraindications (4)].
Medication Overuse Headache
Inform patients that use of drugs to treat acute migraines for 10 or more days per month may lead to an exacerbation of headache, and encourage patients to record headache frequency and drug use (e.g., by keeping a headache diary) [see Warnings and Precautions (5.6)].
Inform patients about the risk of serotonin syndrome with the use of eletriptan or other triptans, particularly during combined use with selective serotonin reuptake inhibitors (SSRIs) or serotonin and norepinephrine reuptake inhibitors (SNRIs) [see Warnings and Precautions (5.7) and Drug Interactions (7.3)].
Inform patients that eletriptan should not be used during pregnancy unless the potential benefit justifies the potential risk to the fetus [see Use in Specific Populations (8.1)].
Inform patients to notify their healthcare provider if they are breastfeeding or plan to breastfeed [see Use in Specific Populations (8.3)].
