2 DOSAGE AND ADMINISTRATION

2.1 Dosing Information

The recommended starting dose for PMS-Zolmitriptan ODT nasal spray in adult and pediatric patients 12 years of age and older is 2.5 mg. As the individual response to PMS-Zolmitriptan ODT nasal spray may vary, the dose should be adjusted on an individual basis. The maximum recommended single dose of PMS-Zolmitriptan ODT is 5 mg.

If the migraine has not resolved by 2 hours after taking PMS-Zolmitriptan ODT, or returns after a transient improvement, another dose may be administered at least 2 hours after the previous dose.

The maximum daily dose should not exceed 10 mg in any 24‑hour period.

The safety of PMS-Zolmitriptan ODT in the treatment of an average of more than four headaches in a 30‑day period has not been established.

2.2 Dosing in Patients with Hepatic Impairment

PMS-Zolmitriptan ODT nasal spray is not recommended in patients with moderate to severe hepatic impairment because of increased PMS-Zolmitriptan ODT blood levels in these patients and elevation of blood pressure in some of these patients. The recommended dosage of PMS-Zolmitriptan ODT nasal spray in patients with mild hepatic impairment is the same as for patients with normal hepatic function [see Dosage and Administration , Warnings and Precautions (5.8), Use in Specific Populations (8.6) and Clinical Pharmacology (12.3) ].

2.3 Dosing in Patients taking Cimetidine

If PMS-Zolmitriptan ODT is co‑administered with cimetidine, limit the maximum single dose of PMS-Zolmitriptan ODT to 2.5 mg, not to exceed 5 mg in any 24‑hour period [see Drug Interactions (7.4) and Clinical Pharmacology (12.3) ].

5 WARNINGS AND PRECAUTIONS

5.1 Myocardial Ischemia, Myocardial Infarction, and Prinzmetal’s Angina

PMS-Zolmitriptan ODT is contraindicated in patients with ischemic or vasospastic coronary artery disease (CAD). There have been rare reports of serious cardiac adverse reactions, including acute myocardial infarction, occurring within a few hours following administration of PMS-Zolmitriptan ODT. Some of these reactions occurred in patients without known CAD. 5-HT1 agonists including PMS-Zolmitriptan ODT 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 PMS-Zolmitriptan ODT. Do not administer PMS-Zolmitriptan ODT 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 administrating the first PMS-Zolmitriptan ODT dose in a medically-supervised setting and performing an electrocardiogram (ECG) immediately following PMS-Zolmitriptan ODT administration. For such patients, consider periodic cardiovascular evaluation in intermittent long-term users of PMS-Zolmitriptan ODT.

5.2 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 PMS-Zolmitriptan ODT if these disturbances occur. Patients with Wolff-Parkinson‑White Syndrome or arrhythmias associated with other cardiac accessory conduction pathway disorders should not receive PMS-Zolmitriptan ODT [see Contraindications ].

5.3 Chest, Throat, Neck, and/or Jaw Pain/Tightness/Pressure

As with other 5‑HT1 agonists, sensations of tightness, pain, pressure, and heaviness in the precordium, throat, neck, and jaw commonly occur after treatment with PMS-Zolmitriptan ODT and is 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-HT1 agonists [see Contraindications (4) ].

5.4 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. Discontinue PMS-Zolmitriptan ODT 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 symptoms atypical for migraine, other potentially serious neurological conditions should be excluded. PMS-Zolmitriptan ODT should not be administered to patients with a history of stroke or transient ischemic attack [see Contraindications ].

5.5 Other Vasospasm Reactions

5‑HT1 agonists, including PMS-Zolmitriptan ODT, 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 vasospasm reaction following the use of any 5‑HT1 agonist, the suspected vasospasm reaction should be ruled out before receiving additional PMS-Zolmitriptan ODT doses [see Contraindications (4) ].

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.

5.6 Medication Overuse Headache

Overuse of acute migraine drugs 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.

5.7 Serotonin Syndrome

Serotonin syndrome may occur with triptans, including PMS-Zolmitriptan ODT, particularly during co-administration with selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), and MAO inhibitors [see Drug Interactions (7.5) ]. 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 rapidly occurs within minutes to hours of receiving a new or a greater dose of a serotonergic medication. PMS-Zolmitriptan ODT treatment should be discontinued if serotonin syndrome is suspected [see Drug Interactions (7.5) and Patient Counseling Information (17) ].

5.8 Increase in Blood Pressure

Significant elevations in systemic blood pressure have been reported in patients treated with 5‑HT1 agonists including patients without a history of hypertension. Very rarely these increases in blood pressure have been associated with significant clinical events. In healthy subjects treated with 5 mg of PMS-Zolmitriptan ODT oral tablet, an increase of 1 and 5 mm Hg in the systolic and diastolic blood pressure, respectively, was seen. In a study of patients with moderate to severe liver impairment, 7 of 27 patients experienced 20 to 80 mm Hg elevations in systolic and/or diastolic blood pressure after a dose of 10 mg of PMS-Zolmitriptan ODT oral tablet. As with all triptans, blood pressure should be monitored in ZOMIG‑treated patients. PMS-Zolmitriptan ODT is contraindicated in patients with uncontrolled hypertension [see Contraindications (4) ].

6.1 Clinical 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

Among 460 patients treating 1180 single attacks with PMS-Zolmitriptan ODT nasal spray in a blinded placebo-controlled trial (Study 1), there was a low withdrawal rate related to adverse reactions: 5 mg (1.3%), 2.5 mg (0%), and placebo (0.4%). None of the withdrawals were due to a serious event. One patient was withdrawn due to abnormal ECG changes from baseline that were incidentally found 23 days after the last dose of PMS-Zolmitriptan ODT nasal spray.

The most common adverse reactions (≥5% and > placebo) in any dosage strength in clinical trials for PMS-Zolmitriptan ODT nasal spray were: unusual taste, paresthesia, hyperesthesia, and dizziness. The incidence of adverse reactions was generally dose‑related.

Table 1 lists the adverse reactions from the controlled clinical trial (Study 1) that occurred in ≥2% of patients in either the 2.5 or 5 mg PMS-Zolmitriptan ODT nasal spray dose groups and with an incidence greater than placebo.

In Study 1, adverse reactions occurring in ≥1% and < 2% of patients in all attacks in either PMS-Zolmitriptan ODT nasal spray dose group and with incidence greater than that of placebo were: abdominal pain, chills, throat pressure, facial edema, chest pressure, palpitation, dysphagia, arthralgia, myalgia, and depersonalization.

The incidence of adverse reactions in controlled clinical trials was not affected by gender, weight, or age of the patients (18-39 vs. 40-65 years of age), or presence of aura. There were insufficient data to assess the impact of race on the incidence of adverse reactions.

Local Adverse Reactions:

Among 460 patients using PMS-Zolmitriptan ODT 2.5 mg or 5 mg in the controlled clinical trial, approximately 3% noted local irritation or soreness at the site of administration. Adverse reactions of any kind, perceived in the nasopharynx (which may include systemic effects of triptans) were severe in about 1% of patients and approximately 57% resolved in 1 hour. Nasopharyngeal examinations, in a subset of patients participating in two long term trials of up to one year duration, failed to demonstrate any clinically significant changes with repeated use of PMS-Zolmitriptan ODT nasal spray.

All nasopharyngeal adverse reactions with an incidence of ≥ 2% of patients in any PMS-Zolmitriptan ODT nasal spray dose groups are included in Table 1.

Other Adverse Reactions:

In the paragraphs that follow, the frequencies of less commonly reported adverse clinical reactions are presented. Because the reports include reactions observed in open and uncontrolled studies, the role of PMS-Zolmitriptan ODT in their causation cannot be reliably determined. Furthermore, variability associated with adverse reaction reporting, the terminology used to describe adverse reactions, etc., limit the value of the quantitative frequency estimates provided. Reaction frequencies are calculated as the number of patients who used PMS-Zolmitriptan ODT nasal spray and reported a reaction divided by the total number of patients exposed to PMS-Zolmitriptan ODT nasal spray (n=3059). All reported reactions are included except those already listed in the previous table, those too general to be informative, and those not reasonably associated with the use of the drug. Reactions are further classified within body system categories and enumerated in order of decreasing frequency using the following definitions: infrequent adverse reactions are those occurring in 1/100 to 1/1,000 patients and rare adverse reactions are those occurring in fewer than 1/1,000 patients.

General: Infrequent: allergic reactions.

Cardiovascular: Infrequent: arrhythmias, hypertension, syncope and tachycardia. Rare: angina pectoris and myocardial infarct.

Digestive: Rare: stomatitis.

Neurological: Infrequent: agitation, amnesia, anxiety, depression, insomnia, and nervousness. Rare: convulsions.

Respiratory: Infrequent: bronchitis, increased cough, dyspnea, epistaxis, laryngeal edema, pharyngitis, rhinitis, and sinusitis.

Skin: Infrequent: pruritus, rash, and urticaria.

Urogenital: Infrequent: polyuria and urinary urgency. Rare: urinary frequency.

Special senses: Infrequent: tinnitus. Rare: conjunctivitis, dry eye, and visual field defect.

The adverse reaction profile seen with PMS-Zolmitriptan ODT nasal spray is similar to that seen with PMS-Zolmitriptan ODT tablets and ZOMIG-ZMT tablets except for the occurrence of local adverse reactions from the nasal spray (see PMS-Zolmitriptan ODT tablet/ZOMIG‑ZMT oral disintegrating tablet Prescribing Information).

Pediatric Patients 12 to 17 Years of Age

The safety of PMS-Zolmitriptan ODT nasal spray in the acute treatment of migraine in pediatric patients 12 to 17 years of age was established in two studies [see Pediatric Use (8.4) and Clinical Studies (14.2)].

The most common adverse reactions (incidence of ≥2% of pediatric patients receiving 2.5 mg and 5 mg PMS-Zolmitriptan ODT nasal spray and numerically greater than placebo) after a single dose are summarized in Table 2. Dysgeusia (unusual taste) was the most common adverse reaction, with a numerically greater incidence for patients receiving PMS-Zolmitriptan ODT compared to placebo (10% vs. 2%). Other common adverse reactions were nasal discomfort, dizziness, oropharyngeal pain, and nausea.

Table 2 lists the adverse reactions from the pooled placebo-controlled studies that occurred in ≥ 2% of pediatric patients 12 to 17 years of age in either the 2.5 mg or 5 mg PMS-Zolmitriptan ODT dose groups and with an incidence greater than placebo.

The adverse reaction profile was similar across gender. There were insufficient data to assess the impact of race on the incidence of adverse reactions.

6.2 Postmarketing Experience

The following adverse reactions were identified during post approval use of PMS-Zolmitriptan ODT. 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.

The reactions enumerated include all except those already listed in the Clinical Trials Experience section above or the Warnings and Precautions section.

Hypersensitivity Reactions:

There have been reports of anaphylaxis, anaphylactoid, and hypersensitivity reactions including angioedema in patients receiving PMS-Zolmitriptan ODT. PMS-Zolmitriptan ODT is contraindicated in patients with a history of hypersensitivity reaction to PMS-Zolmitriptan ODT.

7 DRUG INTERACTIONS

If co‑administered with cimetidine: Maximum single dose of 2.5 mg, not to exceed 5 mg in any 24-hour period.

7.1 Ergot-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 PMS-Zolmitriptan ODT within 24 hours of each other is contraindicated [see Contraindications (4) ].

7.2 MAO-A Inhibitors

MAO-A inhibitors increase the systemic exposure of PMS-Zolmitriptan ODT. Therefore, the use of PMS-Zolmitriptan ODT in patients receiving MAO-A inhibitors is contraindicated [see Contraindications and Clinical Pharmacology (12.3) ].

7.3 5-HT1B/1D agonists (e.g. triptans)

Concomitant use of other 5-HT1B/1D agonists (including triptans) within 24 hours of PMS-Zolmitriptan ODT treatment is contraindicated because the risk of vasospastic reactions may be additive [see Contraindications (4) ].

7.4 Cimetidine

Following administration of cimetidine, the half‑life and AUC of PMS-Zolmitriptan ODT and its active metabolites were approximately doubled [see Clinical Pharmacology ]. If cimetidine and PMS-Zolmitriptan ODT are used concomitantly, limit the maximum single dose of PMS-Zolmitriptan ODT to 2.5 mg, not to exceed 5 mg in any 24-hour period [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3) ].

7.5 Selective Serotonin Reuptake Inhibitors/Serotonin Norepinephrine Reuptake Inhibitors and Serotonin Syndrome

Cases of life-threatening serotonin syndrome have been reported during combined use of selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs) and triptans [see Warnings and Precautions (5.7) ].

8 USE IN SPECIFIC POPULATIONS

Pregnancy: Based on animal data, may cause fetal harm.

8.1 Pregnancy

Pregnancy Category C. There are no adequate and well-controlled studies in pregnant women; therefore, PMS-Zolmitriptan ODT should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. In reproductive toxicity studies in rats and rabbits, oral administration of PMS-Zolmitriptan ODT to pregnant animals resulted in embryolethality and fetal abnormalities (malformations and variations) at clinically relevant exposures.

When PMS-Zolmitriptan ODT was administered to pregnant rats during the period of organogenesis at oral doses of 100, 400, and 1200 mg/kg/day (plasma exposures (AUCs) ≈280, 1100, and 5000 times the human AUC at the maximum recommended human dose (MRHD) of 10 mg/day), there was a dose-related increase in embryolethality. A no-effect dose for embryolethality was not established. When PMS-Zolmitriptan ODT was administered to pregnant rabbits during the period of organogenesis at oral doses of 3, 10, and 30 mg/kg/day (plasma AUCs ≈1, 11, and 42 times the human AUC at the MRHD), there were increases in embryolethality and in fetal malformations and variations. The no-effect dose for adverse effects on embryo-fetal development was associated with a plasma AUC similar to that in humans at the MRHD. When female rats were given PMS-Zolmitriptan ODT during gestation, parturition, and lactation at oral doses of 25, 100, and 400 mg/kg/day (plasma AUCs ≈70, 280, and 1100 times that in human at the MRHD), an increased incidence of hydronephrosis was found in the offspring. The no-effect dose was associated with a plasma AUC ≈280 times that in humans at the MRHD.

8.3 Nursing Mothers

It is not known whether PMS-Zolmitriptan ODT is excreted in human milk. Because many drugs are excreted in human milk, and because of the potential for serious adverse reactions in nursing infants from PMS-Zolmitriptan ODT, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. In rats, oral dosing with PMS-Zolmitriptan ODT resulted in levels in milk up to 4 times higher than in plasma.

8.4 Pediatric Use

Safety and effectiveness of PMS-Zolmitriptan ODT in pediatric patients under 12 years of age have not been established.

The efficacy of PMS-Zolmitriptan ODT nasal spray in the acute treatment of migraine in pediatric patients 12 to 17 years of age was established in a placebo-controlled study with a total of 81 pediatric patients receiving PMS-Zolmitriptan ODT 2.5 mg and 229 pediatric patients receiving PMS-Zolmitriptan ODT 5 mg [see Clinical Studies ].

In an earlier study with a different design, PMS-Zolmitriptan ODT 5 mg nasal spray was evaluated in the acute treatment of migraine headache in 171 pediatric patients 12 to 17 years of age. In that study, the efficacy of PMS-Zolmitriptan ODT nasal spray was not established.

The safety of PMS-Zolmitriptan ODT nasal spray in the acute treatment of migraine in pediatric patients 12 to 17 years of age was established in two placebo-controlled studies with a total of 81 pediatric patients receiving PMS-Zolmitriptan ODT 2.5 mg and 431 pediatric patients receiving PMS-Zolmitriptan ODT 5 mg [see Adverse Reactions (6.1) ].

The safety of PMS-Zolmitriptan ODT nasal spray in pediatric patients 12 to 17 years of age is similar to the profile observed in adults [see Adverse Reactions (6.1) ].

In the postmarketing experience with triptans, including PMS-Zolmitriptan ODT, there is a limited number of reports that describe pediatric patients who have experienced clinically serious adverse events; those that were reported are similar in nature to those reported rarely in adults.

8.5 Geriatric Use

Clinical studies of PMS-Zolmitriptan ODT 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. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting 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 PMS-Zolmitriptan ODT [see Warnings and Precautions (5.1) ]. The pharmacokinetics of PMS-Zolmitriptan ODT were similar in geriatric patients (aged > 65 years) compared to younger patients [see Clinical Pharmacology (12.3) ].

8.6 Hepatic Impairment

The effect of hepatic disease on the pharmacokinetics of PMS-Zolmitriptan ODT nasal spray has not been evaluated. After oral administration, PMS-Zolmitriptan ODT blood levels were increased in patients with moderate to severe hepatic impairment, and significant elevation in blood pressure was observed in some of these patients [see Warnings and Precautions (5.8) ]. PMS-Zolmitriptan ODT nasal spray is not recommended in patients with moderate to severe hepatic impairment [see Dosage and Administration (2.2) and Clinical Pharmacology (12.3) ].

10 OVERDOSAGE

There is no experience with acute overdose. Clinical study subjects receiving single 50 mg oral doses of PMS-Zolmitriptan ODT commonly experienced sedation.

The elimination half-life of PMS-Zolmitriptan ODT is 3 hours [see Clinical Pharmacology (12.1) ] and therefore monitoring of patients after overdose with PMS-Zolmitriptan ODT should continue for at least 15 hours or while symptoms or signs persist.

There is no specific antidote to PMS-Zolmitriptan ODT. In cases of severe intoxication, intensive care procedures are recommended, including establishing and maintaining a patent airway, ensuring adequate oxygenation and ventilation, and monitoring and support of the cardiovascular system.

It is unknown what effect hemodialysis or peritoneal dialysis has on the plasma concentrations of PMS-Zolmitriptan ODT.

11 DESCRIPTION

PMS-Zolmitriptan ODT® (zolmitriptan) Nasal Spray contains PMS-Zolmitriptan ODT, which is a selective 5-hydroxytryptamine 1B/1D (5-HT1B/1D) receptor agonist. PMS-Zolmitriptan ODT is chemically designated as (S)-4-[[3-[2-(dimethylamino)ethyl]-1H-indol-5-yl]methyl]-2-oxazolidinone and has the following chemical structure:


The empirical formula is C16H21N3O2, representing a molecular weight of 287.36. PMS-Zolmitriptan ODT is a white to almost white powder that is readily soluble in water. PMS-Zolmitriptan ODT Nasal Spray is supplied as a clear to pale yellow solution of PMS-Zolmitriptan ODT, buffered to a pH 5.0. Each PMS-Zolmitriptan ODT Nasal Spray contains 2.5 mg or 5 mg of PMS-Zolmitriptan ODT in a 100‑µL unit dose aqueous buffered solution containing citric acid, anhydrous, USP, disodium phosphate dodecahydrate USP and purified water USP.

PMS-Zolmitriptan ODT Nasal Spray is hypertonic. The osmolarity of PMS-Zolmitriptan ODT Nasal Spray for 2.5 mg is 360 to 420 mOsmol, and for 5 mg is 420 to 470 mOsmol.

chemical structure

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

PMS-Zolmitriptan ODT binds with high affinity to human recombinant 5‑HT1D and 5‑HT1B receptors, and moderate affinity for 5‑HT1A receptors. The N‑desmethyl metabolite also has high affinity for 5‑HT1B/1D and moderate affinity for 5‑HT1A receptors.

Current theories proposed to explain the etiology of migraine headache suggest that symptoms are due to local cranial vasodilatation and/or to the release of sensory neuropeptides through nerve endings in the trigeminal system. The therapeutic activity of PMS-Zolmitriptan ODT 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.

12.3 Pharmacokinetics

Absorption

PMS-Zolmitriptan ODT nasal spray is rapidly absorbed via the nasopharynx as detected in a Photon Emission Tomography (PET) study using 11C PMS-Zolmitriptan ODT. The mean relative bioavailability of the nasal spray formulation is 102%, compared with the oral tablet. PMS-Zolmitriptan ODT was detected in plasma by 5 minutes and peak plasma concentration generally was achieved by 3 hours. The time at which maximum plasma concentrations were observed was similar after single (1 day) or multiple (4 days) nasal dosing. Plasma concentrations of PMS-Zolmitriptan ODT are sustained for 4 to 6 hours after dosing. PMS-Zolmitriptan ODT and its active N-desmethyl metabolite display linear kinetics after single or multiple doses of PMS-Zolmitriptan ODT nasal spray over the dose range of 0.1 to 10 mg.

The pharmacokinetics of the N-desmethyl metabolite are similar to that of PMS-Zolmitriptan ODT for all nasal spray dosages. The N-desmethyl metabolite is detected in plasma by 15 minutes and peak plasma concentration is generally achieved by 3 hours after administration. Food has no significant effect on the bioavailability of PMS-Zolmitriptan ODT.

Distribution

Plasma protein binding of PMS-Zolmitriptan ODT is 25% over the concentration range of 10‑1000 ng/mL. The mean apparent volume of distribution for PMS-Zolmitriptan ODT nasal spray formulation is 8.4 L/kg.

Metabolism

PMS-Zolmitriptan ODT is converted to an active N‑desmethyl metabolite such that the metabolite concentrations are about two-thirds that of PMS-Zolmitriptan ODT. Because the 5HT1B/1D potency of the metabolite is 2 to 6 times that of the parent compound, the metabolite may contribute a substantial portion of the overall effect after PMS-Zolmitriptan ODT administration.

Excretion

The mean elimination half life for PMS-Zolmitriptan ODT and N‑desmethyl metabolite following single or multiple nasal spray administration are approximately 3 hours, similar to the half-life values seen after oral tablet administration.

In a study with orally administered PMS-Zolmitriptan ODT, total radioactivity recovered in urine and feces was 65% and 30% of the administered dose, respectively. In urine, unchanged PMS-Zolmitriptan ODT and N‑desmethyl metabolite accounted for 8% and 4% of the dose, respectively, whereas the inactive indole acetic acid and N‑oxide metabolites accounted for 31% and 7% of the dose, respectively.

Mean total plasma clearance for PMS-Zolmitriptan ODT nasal spray is 25.9 mL/min/kg, of which one-sixth is renal clearance. The renal clearance is greater than the glomerular filtration rate suggesting renal tubular secretion.

Specific Populations

Age:

The pharmacokinetics of orally administered PMS-Zolmitriptan ODT in healthy elderly non‑migraineur volunteers (age 65‑76 yrs) was similar to those in younger non‑migraineur volunteers (age 18‑39 yrs).

Sex:

Mean plasma concentrations of orally administered PMS-Zolmitriptan ODT were up to 1.5‑fold higher in females than males.

Race:

There are no significant differences in the pharmacokinetics of orally administered PMS-Zolmitriptan ODT in Japanese and Caucasians.

Renal Impairment:

The effect of renal impairment on the pharmacokinetics of PMS-Zolmitriptan ODT nasal spray has not been evaluated. After orally dosing PMS-Zolmitriptan ODT, renal clearance was reduced by 25% in patients with severe renal impairment (Clcr ≥ 5 ≤ 25 mL/min) compared with the normal group (Clcr ≥ 70 mL/min); no significant change in clearance was observed in the moderately renally impaired group (Clcr ≥ 26 ≤ 50 mL/min).

Hepatic Impairment:

The effect of hepatic disease on the pharmacokinetics of PMS-Zolmitriptan ODT nasal spray has not been evaluated. In patients with severe hepatic impairment, the mean Cmax, Tmax, and AUC of PMS-Zolmitriptan ODT dosed orally were increased 1.5‑fold, 2‑fold (2 vs. 4 hours), and 3‑fold, respectively, compared to subjects with normal hepatic function. Seven out of 27 patients experienced 20 to 80 mm Hg elevations in systolic and/or diastolic blood pressure after a 10 mg PMS-Zolmitriptan ODT dose [see Dosage and Administration (2.2) and Use in Specific Populations (8.6) ].

Hypertensive Patients:

No differences in the pharmacokinetics of oral PMS-Zolmitriptan ODT or its effects on blood pressure were seen in mild to moderate hypertensive volunteers compared with normotensive controls.

Drug Interactions

All drug interaction studies were performed in healthy volunteers using a single 10 mg dose of PMS-Zolmitriptan ODT and a single dose of the other drug except where otherwise noted. Eight drug interaction studies have been performed with PMS-Zolmitriptan ODT tablets and one study (xylometazoline) was performed with nasal spray.

Xylometazoline:

An in vivo drug interaction study with PMS-Zolmitriptan ODT nasal spray indicated that 1 spray (100 µL dose) of xylometazoline (0.1% w/v), a decongestant, administered 30 minutes prior to a 5 mg nasal dose of PMS-Zolmitriptan ODT did not alter the pharmacokinetics of PMS-Zolmitriptan ODT.

Fluoxetine:

The pharmacokinetics of PMS-Zolmitriptan ODT, as well as its effect on blood pressure, were unaffected by 4 weeks of pre‑treatment with oral fluoxetine (20 mg/day).

MAO Inhibitors:

Following one week of administration of moclobemide (150 mg twice‑daily), a specific MAO‑A inhibitor, there was an increase of about 25% in both Cmax and AUC for PMS-Zolmitriptan ODT and a 3‑fold increase in the Cmax and AUC of the active N‑desmethyl metabolite of PMS-Zolmitriptan ODT [see Contraindications (4) and Drug Interactions (7.2) ].

Selegiline, a selective MAO‑B inhibitor, at a dose of 10 mg/day for 1 week, had no effect on the pharmacokinetics of PMS-Zolmitriptan ODT and its metabolite.

Propranolol:

Cmax and AUC of PMS-Zolmitriptan ODT increased 1.5‑fold after one week of dosing with propranolol (160 mg/day). Cmax and AUC of the N‑desmethyl metabolite were reduced by 30% and 15%, respectively. There were no interactive effects on blood pressure or pulse rate following administration of propranolol with PMS-Zolmitriptan ODT.

Acetaminophen:

A single 1g dose of acetaminophen does not alter the pharmacokinetics of PMS-Zolmitriptan ODT and its N‑desmethyl metabolite. However, PMS-Zolmitriptan ODT delayed the Tmax of acetaminophen by one hour.

Metoclopramide:

A single 10 mg dose of metoclopramide had no effect on the pharmacokinetics of PMS-Zolmitriptan ODT or its metabolites.

Oral Contraceptives:

Retrospective analysis of pharmacokinetic data across studies indicated that mean Cmax and AUC of PMS-Zolmitriptan ODT were 30% and 50% higher, respectively, and Tmax was delayed by one-half hour in females taking oral contraceptives compared to females not taking oral contraceptives. The effect of PMS-Zolmitriptan ODT on the pharmacokinetics of oral contraceptives has not been studied.

Cimetidine:

Following the administration of cimetidine, the half-life and AUC of a 5 mg dose of PMS-Zolmitriptan ODT and its active metabolite were approximately doubled. A dosage adjustment is therefore required [see Drug Interactions (7.4) ].

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis

PMS-Zolmitriptan ODT was administered to mice and rats at doses up to 400 mg/kg/day. Mice were dosed for 85 weeks (males) and 92 weeks (females); rats were dosed for 101 weeks (males) and 86 weeks (females). There was no evidence of drug-induced tumors in mice at plasma exposures (AUC) up to approximately 700 times that in humans at the maximum recommended human dose (MRHD) of 10 mg/day. In rats, there was an increase in the incidence of thyroid follicular cell hyperplasia and thyroid follicular cell adenomas in male rats receiving 400 mg/kg/day. No increase in tumors was observed in rats at 100 mg/kg/day, a dose associated with a plasma AUC ≈700 times that in humans at the MRHD.

Mutagenesis

PMS-Zolmitriptan ODT was positive in an in vitro bacterial reverse mutation (Ames) assay and in an in vitro chromosomal aberration assay in human lymphocytes. PMS-Zolmitriptan ODT was negative in an in vitro mammalian gene cell mutation (CHO/HGPRT) assay and in oral in vivo micronucleus assays in mouse and rat.

Impairment of Fertility

Studies of male and female rats administered PMS-Zolmitriptan ODT prior to and during mating and up to implantation showed no impairment of fertility at oral doses up to 400 mg/kg/day. The plasma exposure (AUC) at this dose was approximately 3000 times that in humans at the MRHD.

14 CLINICAL STUDIES

14.1 Adults

The efficacy of PMS-Zolmitriptan ODT nasal spray 2.5 mg and 5 mg in the acute treatment of migraine headache with or without aura in adults was demonstrated in Study 1, a randomized, outpatient, double-blind, placebo-controlled trial.

In Study 1, 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 15, 30, 45 minutes and 1, 2, and 4 hours after dosing. Pain-free response rates and associated symptoms such as nausea, photophobia, and phonophobia were also assessed. A dose of escape medication was allowed 4 to 24 hours after the initial treatment for persistent and recurrent headache.

In Study 1, of the patients taking PMS-Zolmitriptan ODT nasal spray 2.5 mg or 5 mg, 83% were female and 99% were Caucasian, with a mean age of 41 years.

The two-hour headache response rates in patients treated with PMS-Zolmitriptan ODT nasal spray were significantly higher among patients receiving PMS-Zolmitriptan ODT nasal spray at all doses, compared with placebo.

The estimated probability of achieving an initial headache response following treatment with PMS-Zolmitriptan ODT nasal spray is depicted in Figure 1.

Figure 1: Estimated probability of achieving an initial headache response after treatment in Study 1

Note: Figure 1 shows the Kaplan-Meier plot of the probability over time of obtaining headache response (moderate or severe headache improving to mild or no pain) following treatment with PMS-Zolmitriptan ODT nasal spray. The estimates displayed are based on a placebo-controlled, outpatient trial providing evidence of efficacy. Patients not achieving headache response or taking additional treatment prior to 4 hours were censored to 4 hours.

For patients with migraine associated photophobia, phonophobia, and nausea at baseline, there was a decreased incidence of these symptoms following administration of PMS-Zolmitriptan ODT nasal spray as compared with placebo.

Four 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 patients taking a second dose or other medication for migraine over the 24 hours following the initial dose of study treatment is summarized in Figure 2.

Figure 2: Estimated probability of patients taking an escape medication within the 24 hours following the initial dose of study treatment in Study 1

*This Kaplan-Meier plot is based on data obtained from the placebo-controlled clinical trial. Patients not using additional treatments were censored at 24 hours. The plot includes both patients who had headache response at 2 hours and those who had no response to the initial dose. It should be noted that the protocol did not allow remedication within 4 hours post dose.

The efficacy of PMS-Zolmitriptan ODT was unaffected by presence of aura; presence of headache upon awakening, relationship to menses; gender, age or weight of the patient; or presence of pre‑treatment nausea.

The efficacy of PMS-Zolmitriptan ODT nasal spray 5 mg was further supported by an interim analysis of another similarly designed trial. The 2-hour headache response rates for the first 210 subjects in that study for PMS-Zolmitriptan ODT 5 mg and placebo were 70% and 47%, respectively (N=108 and 102, respectively, p=0.0006).

14.2 Pediatric Patients 12 to 17 Years of Age

The efficacy of PMS-Zolmitriptan ODT nasal spray in the acute treatment of migraine headache with or without aura in pediatric patients 12 to 17 years of age was demonstrated in Study 2, a randomized, double-blind, placebo-controlled trial with a single-blind run-in period.

Patients had to have an established diagnosis of migraine (history indicating the presence of migraine for at least 1 year) with or without aura with a typical untreated migraine headache attack lasting 3 hours or more. The study included treatment of a single migraine headache attack with 1 dose of single-blind placebo during the 30-day run-in period. If the patient met all conditions for randomization, including a lack of response to the placebo run-in, a subsequent single migraine headache attack was treated with 1 blinded dose of either PMS-Zolmitriptan ODT nasal spray 5 mg, 2.5 mg, or matching placebo.

In Study 2, of the patients taking PMS-Zolmitriptan ODT nasal spray 2.5 mg or 5 mg, 62% were female and 93% were Caucasian, with a mean age of 14 years (range 12 to 17 years).

Study 2 evaluated the proportion of pediatric patients 12 to 17 years of age who had no headache pain at 2 hours following treatment. Headache response (defined as a reduction in migraine-related headache pain severity from moderate or severe pain to mild or no pain) and the absence of nausea, photophobia, and phonophobia at 2 hours post treatment were also assessed. As shown in Table 4, the percentage of pediatric patients 12 to 17 years of age with no headache pain at 2 hours following treatment was significantly higher for PMS-Zolmitriptan ODT nasal spray 5 mg than placebo.
