🩺 Clinical

Label name RIZATRIPTAN 10 MG ODT Ingredient Rizatriptan Benzoate
📖 What it is MedlinePlus · NLM

Rizatriptan is used to treat migraine headaches (severe, throbbing headaches that sometimes cause nausea and sensitivity to sound and light). Rizatriptan is in a class of medications called selective serotonin receptor agonists. It works by narrowing blood vessels in the brain, stopping pain signals from being sent, which stops the release of certain natural substances that cause pain, nausea, and other symptoms of migraine. Rizatriptan does not stop migraine attacks from coming or reduce the number of headaches you have.

7 inactive ingredients listed in the exact product block matched to this NDC.

Where does this data come from?
Data sourced from official FDA Structured Product Labeling (SPL) via DailyMed — ingredient classCode="IACT" elements from the exact product block matched by this NDC. Label-section narrative from DailyMed / the openFDA label index is shown separately when available.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Price systemPer eachPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo No recent Medicaid claims on file for this NDC — rare and low-volume NDCs are suppressed in the public data.
Medicare drug plans payPart D · Q2 2026 $1.01 $18.11 / 18 tablets
Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Rizatriptan (matched by generic name) — the program that covers self-administered drugs. 11 manufacturers.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Rizatriptan. CMS lists 3 products for this generic; we show the highest-spend one. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 33342-094-23, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 33342-0094-23, written without dashes as 33342009423. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 33342-0094-23, the first segment (33342) is the labeler code FDA assigned to Macleods Pharmaceuticals Limited; the middle segment (0094) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (23) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Macleods Pharmaceuticals Limited. Listing status can change — the directory data on this page refreshes weekly.
Does this product come in other package sizes?
Yes — the FDA directory lists 10 other package presentations of this same product, including 3 tablets (33342-0094-52), 3 tablets (33342-0094-72), 3 tablets (33342-0094-73). Each has its own NDC and its own page — see the package list near the top of this page.
Who lists this product with the FDA?
Macleods Pharmaceuticals Limited is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?

2 DOSAGE & ADMINISTRATION Adults: 5 or 10 mg single dose; separate repeat doses by at least two hours; maximum dose in a 24-hour period: 30 mg ( 2.1 ) Pediatric patients 6 to 17 years: 5 mg single dose in patients less than 40 kg (88 lb); 10 mg single dose in patients 40 kg (88lb) or more ( 2.2 ) Adjust dose if co-administered with propranolol ( 2.4 )

2.1Dosing Information in Adults The recommended starting dose of rizatriptan benzoate orally disintegrating tablets is either 5 mg or 10 mg for the acute treatment of migraines in adults. The 10-mg dose may provide a greater effect than the 5-mg dose, but may have a greater risk of adverse reactions [see Clinical Studies ( 14.1 )]. Redosing in Adults Although the effectiveness of a second dose or subsequent doses has not been established in placebo-controlled trials, if the migraine headache returns, a second dose may be administered 2 hours after the first dose.

The maximum daily dose should not exceed 30 mg in any 24-hour period. The safety of treating, on average, more than four headaches in a 30-day period has not been established.

2.2Dosing Information in Pediatric Patients (Age 6 to 17 Years) Dosing in pediatric patients is based on the patient's body weight. The recommended dose of rizatriptan benzoate orally disintegrating tablets is 5 mg in patients weighing less than 40 kg (88 lb), and 10 mg in patients weighing 40 kg (88 lb) or more. The efficacy and safety of treatment with more than one dose of rizatriptan benzoate orally disintegrating tablets within 24 hours in pediatric patients 6 to 17 years of age have not been established.

2.3Administration of Rizatriptan Benzoate Orally Disintegrating Tablets For rizatriptan benzoate orally disintegrating tablets, administration with liquid is not necessary. Orally disintegrating tablets are packaged in a blister within a carton and patients should not remove the blister from the carton until just prior to dosing. The blister pack should then be peeled open with dry hands and the orally disintegrating tablet placed on the tongue, where it will dissolve and be swallowed with the saliva.

2.4Dosage Adjustment for Patients on Propranolol Adult Patients In adult patients taking propranolol, only the 5-mg dose of rizatriptan benzoate orally disintegrating tablets is recommended, up to a maximum of 3 doses in any 24-hour period (15 mg) [see Drug Interactions ( 7.1 ) and Clinical Pharmacology ( 12.3 )]. Pediatric Patients For pediatric patients weighing 40 kg (88 lb) or more, taking propranolol, only a single 5-mg dose of rizatriptan benzoate orally disintegrating tablets is recommended (maximum dose of 5 mg in a 24-hour period).

Rizatriptan benzoate orally disintegrating tablets should not be prescribed to propranolol-treated pediatric patients who weigh less than 40 kg (88 lb) [see Drug Interactions ( 7.1 ) and Clinical Pharmacology ( 12.3 )].

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS • Myocardial ischemia, myocardial infarction, and Prinzmetal's angina: Perform cardiac evaluation in patients with multiple cardiovascular risk factors ( 5.1 ) • Arrhythmias: Discontinue dosing if occurs ( 5.2 ) • Chest/throat/neck/jaw pain, tightness, pressure, or heaviness; Generally not associated with myocardial ischemia; Evaluate patients at high risk ( 5.3 ) • Cerebral hemorrhage, subarachnoid hemorrhage, and stroke: Discontinue dosing if occurs ( 5.4 ) • Gastrointestinal ischemic events, peripheral vasospastic reactions: Discontinue dosing if occurs ( 5.5 ) • Medication overuse headache: Detoxification may be necessary ( 5.6 ) • Serotonin syndrome: Discontinue dosing if occurs ( 5.7 )

5.1Myocardial Ischemia, Myocardial Infarction, and Prinzmetal's Angina Rizatriptan benzoate should not be given to patients with ischemic or vasospastic coronary artery disease. There have been rare reports of serious cardiac adverse reactions, including acute myocardial infarction, occurring within a few hours following administration of rizatriptan benzoate. Some of these reactions occurred in patients without known coronary artery disease (CAD).

5-HT 1 agonists, including rizatriptan benzoate may cause coronary artery vasospasm (Prinzmetal's Angina), even in patients without a history of CAD. Triptan-naïve patients who have multiple cardiovascular risk factors (e.g., increased age, diabetes, hypertension, smoking, obesity, strong family history of CAD) should have a cardiovascular evaluation prior to receiving rizatriptan benzoate. If there is evidence of CAD or coronary artery vasospasm, rizatriptan benzoate should not be administered [see Contraindications ( 4 )] .

For patients who have a negative cardiovascular evaluation, consideration should be given to administration of the first rizatriptan benzoate dose in a medically-supervised setting and performing an electrocardiogram (ECG) immediately following rizatriptan benzoate administration. Periodic cardiovascular evaluation should be considered in intermittent long-term users of rizatriptan benzoate who have cardiovascular risk factors.

5.2Arrhythmias 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-HT 1 agonists. Discontinue rizatriptan benzoate if these disturbances occur.

5.3Chest, Throat, Neck and/or Jaw Pain/Tightness/Pressure As with other 5-HT 1 agonists, sensations of tightness, pain, pressure, and heaviness in the precordium, throat, neck and jaw commonly occur after treatment with rizatriptan benzoate and are usually non-cardiac in origin. However, if a cardiac origin is suspected, patients should be evaluated. Patients shown to have CAD and those with Prinzmetal's variant angina should not receive 5-HT 1 agonists.

5.4Cerebrovascular Events Cerebral hemorrhage, subarachnoid hemorrhage, and stroke have occurred in patients treated with 5-HT 1 agonists, and some have resulted in fatalities. In a number of cases, it appears possible that the cerebrovascular events were primary, the 5-HT 1 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, transient ischemic attack).

Discontinue rizatriptan benzoate if a cerebrovascular event occurs. As with other acute migraine therapies, before treating headaches in patients not previously diagnosed as migraineurs, and in migraineurs who present with atypical symptoms, care should be taken to exclude other potentially serious neurological conditions. Rizatriptan benzoate should not be administered to patients with a history of stroke or transient ischemic attack [see Contraindications ( 4 )].

6 ADVERSE REACTIONS The following adverse reactions are discussed in more detail in other sections of the labeling: • Myocardial Ischemia, Myocardial Infarction, and Prinzmetal's Angina [see Warnings and Precautions ( 5.1 )]. • Arrhythmias [see Warnings and Precautions ( 5.2 )]. • Chest, Throat, Neck and/or Jaw Pain/Tightness/Pressure [see Warnings and Precautions ( 5.3 )]. • Cerebrovascular Events [see Warnings and Precautions ( 5.4 )]. • Other Vasospasm Reactions [see Warnings and Precautions ( 5.5 )]. • Medication Overuse Headache [see Warnings and Precautions ( 5.6 )]. • Serotonin Syndrome [see Warnings and Precautions ( 5.7 )]. • Increase in Blood Pressure [see Warnings and Precautions ( 5.8 )].

The most common adverse reactions in adults were (incidence ≥ 5% and greater than placebo): asthenia/fatigue, somnolence, pain/pressure sensation and dizziness ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Macleods Pharma USA, Inc. at 1-888-943-3210 or 1-855-926-3384 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .

6.1Clinical Trials Experience 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. Adults Incidence in Controlled Clinical Trials Adverse reactions to rizatriptan benzoate were assessed in controlled clinical trials that included over 3700 adult patients who received single or multiple doses of rizatriptan benzoate tablets.

The most common adverse reactions during treatment with rizatriptan benzoate (≥ 5% in either treatment group and greater than placebo) were asthenia/fatigue, somnolence, pain/pressure sensation and dizziness. These adverse reactions appeared to be dose related. Table 1 lists the adverse reactions (incidence ≥ 2% and greater than placebo) after a single dose of rizatriptan benzoate in adults.

Table 1: Incidence (≥ 2% and Greater than Placebo) of Adverse Reactions After a Single Dose of Rizatriptan Benzoate Tablets or Placebo in Adults Adverse Reactions % of Patients Rizatriptan Benzoate Tablets 5 mg (N=977) Rizatriptan Benzoate Tablets 10 mg (N=1167) Placebo (N=627) Atypical Sensations 4 5 4 Paresthesia 3 4 <2 Pain and other Pressure Sensations 6 9 3 Chest Pain: tightness/pressure and/or heaviness <2 3 1 Neck/throat/jaw: pain/tightness/pressure <2 2 1 Regional Pain: tightness/pressure and/or heaviness <1 2 0 Pain, location unspecified 3 3 <2 Digestive 9 13 8 Dry Mouth 3 3 1 Nausea 4 6 4 Neurological 14 20 11 Dizziness 4 9 5 Headache <2 2 <1 Somnolence 4 8 4 Other Asthenia/fatigue 4 7 2 The frequencies of adverse reactions in clinical trials did not increase when up to three doses were taken within 24 hours.

Adverse reaction frequencies were also unchanged by concomitant use of drugs commonly taken for migraine prophylaxis (including propranolol), oral contraceptives, or analgesics. The incidences of adverse reactions were not affected by age or gender. There were insufficient data to assess the impact of race on the incidence of adverse reactions.

Other Events Observed in Association with the Administration of Rizatriptan Benzoate in Adults In the following section, the frequencies of less commonly reported adverse events are presented that were not reported in other sections of the labeling. Because the reports include events observed in open studies, the role of rizatriptan benzoate in their causation cannot be reliably determined. Furthermore, variability associated with adverse event reporting, the terminology used to describe adverse events, limit the value of the quantitative frequency estimates provided.

Event frequencies are calculated as the number of patients who used rizatriptan benzoate and reported an event divided by the total number of patients exposed to rizatriptan benzoate (N=3716). All reported events occurred at an incidence ≥ 1%, or are believed to be reasona…

7 DRUG INTERACTIONS

7.1Propranolol The dose of rizatriptan benzoate should be adjusted in propranolol-treated patients, as propranolol has been shown to increase the plasma AUC of rizatriptan by 70% [see Dosage and Administration ( 2.4 ) and Clinical Pharmacology ( 12.3 )].

7.2Ergot-Containing Drugs 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 or methysergide) and rizatriptan benzoate within 24 hours is contraindicated [see Contraindications ( 4 )].

7.3Other 5-HT1 Agonists Because their vasospastic effects may be additive, co-administration of rizatriptan benzoate and other 5-HT 1 agonists within 24 hours of each other is contraindicated [see Contraindications ( 4 )] .

7.4SSRIs/SNRIs and Serotonin Syndrome Cases of serotonin syndrome have been reported during co-administration of triptans and selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs) [see Warnings and Precautions ( 5.7 )].

7.5Monoamine Oxidase Inhibitors Rizatriptan benzoate is contraindicated in patients taking MAO-A inhibitors and non-selective MAO inhibitors. A specific MAO-A inhibitor increased the systemic exposure of rizatriptan and its metabolite [see Contraindications ( 4 ) and Clinical Pharmacology ( 12.3 )].

👥 Use in Specific Populations ~3 min read ▾

8 USE IN SPECIFIC POPULATIONS • Pregnancy: Based on animal data, may cause fetal harm ( 8.1 ) • Phenylketonurics: Rizatriptan benzoate orally disintegrating tablets contain phenylalanine ( 8.6 )

8.1Pregnancy Risk Summary Available human data on the use of rizatriptan benzoate in pregnant women are not sufficient to draw conclusions about drug-associated risk for major birth defects and miscarriage. In animal studies, developmental toxicity was observed following oral administration of rizatriptan during pregnancy (decreased fetal body weight in rats) or throughout pregnancy and lactation (increased mortality, decreased body weight, and neurobehavioral impairment in rat offspring) at maternal plasma exposures greater than that expected at therapeutic doses in humans [ see Animal Data ].

In the U.S. general population, the estimated background risk of major birth defects and of miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. The reported rate of major birth defects among deliveries to women with migraine range from 2.2% to 2.9% and the reported rate of miscarriage was 17%, which are similar to rates reported in women without migraine. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk In women with migraine, there is an increased risk of adverse perinatal outcomes in the mother, including pre-eclampsia and gestational hypertension.

Data Human Data The Pregnancy Registry for rizatriptan benzoate did not identify any pattern of congenital anomalies or other adverse birth outcomes over the period of 1998 to 2018. However, the lack of identification of any pattern should be viewed with caution, as the number of prospective reports with outcome information was low and did not provide sufficient power to detect an increased risk of individual birth defects associated with the use of rizatriptan benzoate. Additionally, there was significant loss to follow-up in the prospective pregnancy reports, further complicating this assessment of an association between rizatriptan benzoate and any pattern of congenital anomalies or other adverse birth outcomes.

In a study using data from the Swedish Medical Birth Register, live births to women who reported using triptans or ergots during pregnancy were compared with those of women who did not. Of the 157 births with first-trimester exposure to rizatriptan, 7 infants were born with malformations (relative risk 1.01 [95% CI: 0.40 to 2.08]). A study using linked data from the Medical Birth Registry of Norway to the Norwegian Prescription Database compared pregnancy outcomes in women who redeemed prescriptions for triptans during pregnancy, as well as a migraine disease comparison group who redeemed prescriptions for triptans before pregnancy only, compared with a population control group.

Of the 310 women who redeemed prescriptions for rizatriptan during the first trimester, 10 had infants with major congenital malformations (OR 1.03 [95% CI: 0.55 to 1.93]), while for the 271 women who redeemed prescriptions for rizatriptan before, but not during, pregnancy, 12 had infants with major congenital malformations (OR 1.48 [95% CI: 0.83 to 2.64]), each compared with the population comparison group. Animal Data When rizatriptan (0, 2, 10, or 100 mg/kg/day) was administered orally to pregnant rats throughout organogenesis, a decrease in fetal body weight was observed at the highest doses tested.

At the mid dose (10 mg/kg/day), which was a no-effect dose for adverse effects on embryofetal development, plasma exposure (AUC) was approximately 15 times that in humans at the maximum recommended human dose (MRHD) of 30 mg/day. When rizatriptan (0, 5, 10, or 50 mg/kg/day) was administered orally to pregnant rabbits throughout organogenesis, no adverse fetal effects were observed. Plasma exposure (AUC) at the highest dose tested was 115 times that in humans at the MRHD.

Placental transfer of drug to the fetus was demonstrated in both species. Oral…

🧒 Pediatric Use 99 words ▾

8.4Pediatric Use Safety and effectiveness in pediatric patients under 6 years of age have not been established. The efficacy and safety of rizatriptan benzoate orally disintegrating tablets in the acute treatment of migraine in patients aged 6 to 17 years was established in an adequate and well-controlled study [see Clinical Studies (14.2)]. The incidence of adverse reactions reported for pediatric patients in the acute clinical trial was similar in patients who received rizatriptan benzoate orally disintegrating tablets to those who received placebo.

The adverse reaction pattern in pediatric patients is expected to be similar to that in adults.

🧓 Geriatric Use 139 words ▾

8.5Geriatric Use Clinical studies of rizatriptan benzoate did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. Although the pharmacokinetics of rizatriptan were similar in elderly (aged ≥ 65 years) and in younger adults (n=17), in general, dose selection for an elderly patient should be cautious, starting at the low end of the dosing range.

This reflects the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Geriatric patients who have other cardiovascular risk factors (e.g., diabetes, hypertension, smoking, obesity, strong family history of coronary artery disease) should have a cardiovascular evaluation prior to receiving rizatriptan benzoate [see Warnings and Precautions ( 5.1 )].

🆘 Overdosage 209 words ▾

10 OVERDOSAGE No overdoses of rizatriptan benzoate were reported during clinical trials in adults. Some adult patients who received 40 mg of rizatriptan benzoate either a single dose or as two doses with a 2-hour interdose interval had dizziness and somnolence. In a clinical pharmacology study in which 12 adult subjects received rizatriptan benzoate, at total cumulative doses of 80 mg (given within four hours), two of the subjects experienced syncope, dizziness, bradycardia including third degree AV block, vomiting, and/or incontinence.

In the long-term, open label study, involving 606 treated pediatric migraineurs 12 to 17 years of age (of which 432 were treated for at least 12 months), 151 patients (25%) took two 10-mg doses of rizatriptan benzoate orally disintegrating tablets within a 24-hour period. Adverse reactions for 3 of these patients included abdominal discomfort, fatigue, and dyspnea. In addition, based on the pharmacology of rizatriptan benzoate, hypertension or myocardial ischemia could occur after overdosage.

Gastrointestinal decontamination, (i.e., gastric lavage followed by activated charcoal) should be considered in patients suspected of an overdose with rizatriptan benzoate. Clinical and electrocardiographic monitoring should be continued for at least 12 hours, even if clinical symptoms are not observed. The effects of hemo- or peritoneal dialysis on serum concentrations of rizatriptan are unknown.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Rizatriptan binds with high affinity to human cloned 5-HT 1B/1D receptors. Rizatriptan presumably exerts its therapeutic effects in the treatment of migraine headache by binding to 5-HT 1B/1D receptors located on intracranial blood vessels and sensory nerves of the trigeminal system.

12.3Pharmacokinetics Absorption Rizatriptan is completely absorbed following oral administration. The mean oral absolute bioavailability of the rizatriptan benzoate tablet is about 45%, and mean peak plasma concentrations (C max ) are reached in approximately 1 to 1.5 hours (T max ). The presence of a migraine headache did not appear to affect the absorption or pharmacokinetics of rizatriptan.

Food has no significant effect on the bioavailability of rizatriptan but delays the time to reach peak concentration by an hour. In clinical trials, rizatriptan benzoate was administered without regard to food. The bioavailability and C max of rizatriptan were similar following administration of rizatriptan benzoate tablets and rizatriptan benzoate orally disintegrating tablets, but the rate of absorption is somewhat slower with rizatriptan benzoate orally disintegrating tablets, with T max delayed by up to 0.7 hour.

AUC of rizatriptan is approximately 30% higher in females than in males. No accumulation occurred on multiple dosing. Distribution The mean volume of distribution is approximately 140 liters in male subjects and 110 liters in female subjects.

Rizatriptan is minimally bound (14%) to plasma proteins. Metabolism The primary route of rizatriptan metabolism is via oxidative deamination by monoamine oxidase-A (MAO-A) to the indole acetic acid metabolite, which is not active at the 5-HT 1B/1D receptor. N-monodesmethyl-rizatriptan, a metabolite with activity similar to that of parent compound at the 5-HT 1B/1D receptor, is formed to a minor degree.

Plasma concentrations of N-monodesmethyl-rizatriptan are approximately 14% of those of parent compound, and it is eliminated at a similar rate. Other minor metabolites, the N-oxide, the 6-hydroxy compound, and the sulfate conjugate of the 6-hydroxy metabolite are not active at the 5-HT 1B/1D receptor. Elimination The total radioactivity of the administered dose recovered over 120 hours in urine and feces was 82% and 12%, respectively, following a single 10-mg oral administration of 14 C-rizatriptan.

Following oral administration of 14 C-rizatriptan, rizatriptan accounted for about 17% of circulating plasma radioactivity. Approximately 14% of an oral dose is excreted in urine as unchanged rizatriptan while 51% is excreted as indole acetic acid metabolite, indicating substantial first pass metabolism. The plasma half-life of rizatriptan in males and females averages 2 to 3 hours.

Cytochrome P450 Isoforms Rizatriptan is not an inhibitor of the activities of human liver cytochrome P450 isoforms 3A4/5, 1A2, 2C9, 2C19, or 2E1; rizatriptan is a competitive inhibitor (K=1400 nM) of cytochrome P450 2D6, but only at high, clinically irrelevant concentrations. Special Populations Geriatric: Rizatriptan pharmacokinetics in healthy elderly non-migraineur volunteers (age 65 to 77 years) were similar to those in younger non-migraineur volunteers (age 18 to 45 years). Pediatric: The pharmacokinetics of rizatriptan was determined in pediatric migraineurs 6 to 17 years of age.

Exposures following single dose administration of 5 mg rizatriptan benzoate orally disintegrating tablets to pediatric patients weighing 20-39 kg (44-87 lb) or 10 mg rizatriptan benzoate orally disintegrating tablets to pediatric patients weighing ≥40 kg (88 lb) were similar to those observed following single dose administration of 10 mg rizatriptan benzoate orally disintegrating tablets to adults. Gender : The mean AUC 0-∞ and C max of rizatriptan (10 mg orally) were about 30% and 11% higher in females as compared to males, respectively, while T max occurred at approximately the same time.

Although serious cardiovascular events can occur without warning symptoms, patients should be alert for the signs and symptoms of chest pain, shortness of breath, weakness, slurring of speech, and should ask for medical advice when observing any indicative sign or symptoms.

Patients should be apprised of the importance of this follow-up [see Warnings and Precautions ( 5.1 , 5.2 , 5.4 , 5.5 )] .
