Rasagiline is used alone or in combination with another medication to treat the symptoms of Parkinson's disease (a slowly progressing disease of the nervous system causing a fixed face without expression, tremor at rest, slowing of movements, walking with shuffling steps, stooped posture and muscle weakness). Rasagiline is in a class of medications called monoamine oxidase (MAO) type B inhibitors. It works by increasing the amounts of certain natural substances in the brain.

⏳ Availability & generic status
FDA-approved generic versions are listed, and recent pricing/market data suggests they may be available — see Therapeutic equivalents.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

📄 Full prescribing information FDA SPL
🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE AZILECT (rasagiline tablets) is indicated for the treatment of Parkinson’s disease (PD). AZILECT, a monoamine oxidase (MAO)-B inhibitor (MAOI), is indicated for the treatment of Parkinson’s disease ( 1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Monotherapy: AZILECT 1 mg once daily ( 2.1 ) As adjunct without levodopa: AZILECT 1 mg once daily ( 2.1 ) As adjunct to levodopa: AZILECT 0.5 mg once daily. Increase dose to 1 mg daily as needed for sufficient clinical response ( 2.1 ) Patients taking ciprofloxacin or other CYP1A2 inhibitors: AZILECT 0.5 mg once daily ( 2.2 , 5.4 ) Patients with mild hepatic impairment: AZILECT 0.5 mg once daily. AZILECT should not be used in patients with moderate or severe hepatic impairment ( 2.3 , 5.5 )
2.1General Dosing Recommendations When AZILECT is prescribed as monotherapy or as adjunct therapy in patients not taking levodopa, patients may start AZILECT at the recommended dose of 1 mg administered orally once daily. In patients taking levodopa, with or without other PD drugs (e.g., dopamine agonist, amantadine, anticholinergics), the recommended initial dose of AZILECT is 0.5 mg once daily. If the patient tolerates the daily 0.5 mg dose, but a sufficient clinical response is not achieved, the dose may be increased to 1 mg once daily.
When AZILECT is used in combination with levodopa, a reduction of the levodopa dose may be considered, based upon individual response. The recommended doses of AZILECT should not be exceeded because of risk of hypertension [see Warnings and Precautions ( 5.1 )].
2.2Patients Taking Ciprofloxacin or Other CYP1A2 Inhibitors Patients taking concomitant ciprofloxacin or other CYP1A2 inhibitors should not exceed a dose of AZILECT 0.5 mg once daily [see Warnings and Precautions ( 5.4 ), Drug Interactions ( 7.6 ), and Clinical Pharmacology ( 12.3 )].
2.3Patients with Hepatic Impairment Patients with mild hepatic impairment should not exceed a dose of AZILECT 0.5 mg once daily. AZILECT should not be used in patients with moderate or severe hepatic impairment [see Warnings and Precautions ( 5.5 ), Use in Specific Populations (8.6), and Clinical Pharmacology ( 12.3 )] .

⛔ Contraindications ▾
4 CONTRAINDICATIONS AZILECT is contraindicated for use with meperidine, tramadol, methadone, propoxyphene, and MAO inhibitors (MAOIs), including other selective MAO-B inhibitors, because of risk of serotonin syndrome [see Warnings and Precautions ( 5.2 )] . At least 14 days should elapse between discontinuation of AZILECT and initiation of treatment with these medications. AZILECT is contraindicated for use with St.
John’s wort and with cyclobenzaprine. AZILECT is contraindicated for use with dextromethorphan because of risk of episode of psychosis or bizarre behavior. Concomitant use of meperidine, tramadol, methadone, propoxyphene dextromethorphan, St.
John’s wort, cyclobenzaprine, or another (selective or non-selective) MAO inhibitor ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS May cause hypertension (including severe hypertensive syndromes) at recommended doses ( 5.1 ) May cause serotonin syndrome when used with antidepressants ( 5.2 ) May cause falling asleep during activities of daily living, daytime drowsiness, and somnolence ( 5.3 ) May cause hypotension, especially orthostatic ( 5.6 ) May cause or exacerbate dyskinesia. Decreasing the levodopa dose may lessen or eliminate this side effect ( 5.7 ) May cause hallucinations and psychotic-like behavior ( 5.8 ) May cause impulse control/compulsive behaviors ( 5.9 ) May cause withdrawal-emergent hyperpyrexia and confusion ( 5.10 )
5.1Hypertension Exacerbation of hypertension may occur during treatment with AZILECT. Medication adjustment may be necessary if elevation of blood pressure is sustained. Monitor patients for new onset hypertension or hypertension that is not adequately controlled after starting AZILECT.
In Study 3, AZILECT (1 mg/day) given in conjunction with levodopa, produced an increased incidence of significant blood pressure elevation (systolic > 180 or diastolic > 100 mm Hg) of 4% compared to 3% for placebo [see Adverse Reactions ( 6.1 )] . When used as an adjunct to levodopa (Studies 3 and 4), the risk for developing post-treatment high blood pressure (e.g., systolic > 180 or diastolic >100 mm Hg) combined with a significant increase from baseline (e.g., systolic > 30 or diastolic > 20 mm Hg) was higher for AZILECT (2%) compared to placebo (1%).
Dietary tyramine restriction is not required during treatment with recommended doses of AZILECT. However, certain foods that may contain very high amounts (i.e., more than 150 mg) of tyramine that could potentially cause severe hypertension because of tyramine interaction (including various clinical syndromes referred to as hypertensive urgency, crisis, or emergency) in patients taking AZILECT, even at the recommended doses, due to increased sensitivity to tyramine. Patients should be advised to avoid foods containing a very large amount of tyramine while taking recommended doses of AZILECT because of the potential for large increases in blood pressure including clinical syndromes referred to as hypertensive urgency, crisis, or emergency.
AZILECT is a selective inhibitor of MAO-B at the recommended doses of 0.5 or 1 mg daily. Selectivity for inhibiting MAO-B diminishes in a dose-related manner as the dose is progressively increased above the recommended daily doses.
5.2Serotonin Syndrome Serotonin syndrome has been reported with concomitant use of an antidepressant (e.g., selective serotonin reuptake inhibitors-SSRIs, serotonin-norepinephrine reuptake inhibitors-SNRIs, tricyclic antidepressants, tetracyclic antidepressants, triazolopyridine antidepressants) and a nonselective MAOI (e.g., phenelzine, tranylcypromine) or selective MAO-B inhibitors, such as selegiline (Eldepryl) and rasagiline (AZILECT). Serotonin syndrome has also been reported with concomitant use of AZILECT with meperidine, tramadol, methadone, or propoxyphene.
AZILECT is contraindicated for use with meperidine, tramadol, methadone, propoxyphene, and MAO inhibitors (MAOIs), including other selective MAO-B inhibitors [see Contraindications ( 4 ) and Drug Interactions ( 7.1 , 7.2 , 7.3 )]. In the postmarketing period, potentially life-threatening serotonin syndrome has been reported in patients treated with antidepressants concomitantly with AZILECT. Concomitant use of AZILECT with one of many classes of antidepressants (e.g., SSRIs, SNRIs, triazolopyridine, tricyclic or tetracyclic antidepressants) is not recommended [see Drug Interactions ( 7.5 )] .
The symptoms of serotonin syndrome have included behavioral and cognitive/mental status changes (e.g., confusion, hypomania, hallucinations, agitation, delirium, headache, and coma), autonomic effects (e.g., syncope, shivering, sweating, high fever/hyperthermia, hypertension, tachycardia, nausea, diarrhea), and somatic effects (e.g., muscular rigidity,…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following adverse reactions are described in more detail in the Warnings and Precautions section of the label: Hypertension [see Warnings and Precautions ( 5.1 )] Serotonin Syndrome [see Warnings and Precautions ( 5.2 )] Falling Asleep During Activities of Daily Living and Somnolence [see Warnings and Precautions ( 5.3 )] Hypotension / Orthostatic Hypotension [see Warnings and Precautions ( 5.6 )] Dyskinesia [see Warnings and Precautions ( 5.7 )] Hallucinations / Psychotic-Like Behavior [see Warnings and Precautions ( 5.8 )] Impulse Control /Compulsive Behaviors [see Warnings and Precautions ( 5.9 )] Withdrawal-Emergent Hyperpyrexia and Confusion [see Warnings and Precautions ( 5.10 )] Most common adverse reactions (incidence 3% or greater than placebo): AZILECT monotherapy: flu syndrome, arthralgia, depression, dyspepsia ( 6.1 ) AZILECT used as adjunct without levodopa: peripheral edema, fall, arthralgia, cough, and insomnia ( 6.1 ) AZILECT used as adjunct to levodopa: dyskinesia, accidental injury, weight loss, postural hypotension, vomiting, anorexia, arthralgia, abdominal pain, nausea, constipation, dry mouth, rash, abnormal dreams, fall, and tenosynovitis ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Teva Pharmaceuticals at 1-888-483-8279 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to the incidence of adverse reactions in the clinical trials of another drug and may not reflect the rates of adverse reactions observed in practice. During the clinical development of AZILECT, Parkinson’s disease patients received AZILECT as initial monotherapy (Study 1) and as adjunct therapy (Study 2, Study 3, Study 4). As the populations in these studies differ, not only in the adjunct use of dopamine agonists or levodopa during AZILECT treatment, but also in the severity and duration of their disease, the adverse reactions are presented separately for each study.
Monotherapy Use of AZILECT In Study 1, approximately 5% of the 149 patients treated with AZILECT discontinued treatment due to adverse reactions compared to 2% of the 151 patients who received placebo. The only adverse reaction that led to the discontinuation of more than one patient was hallucinations. The most commonly observed adverse reactions in Study 1 (incidence in AZILECT-treated patients 3% or greater than the incidence in placebo-treated patients) included flu syndrome, arthralgia, depression, and dyspepsia.
Table 1 lists adverse reactions that occurred in 2% or greater of patients receiving AZILECT as monotherapy and were numerically more frequent than in the placebo group in Study 1. Table 1: Adverse Reactions* in Study 1 AZILECT 1 mg (N=149) Placebo (N=151) % of Patients % of Patients Headache 14 12 Arthralgia 7 4 Dyspepsia 7 4 Depression 5 2 Fall 5 3 Flu syndrome 5 1 Conjunctivitis 3 1 Fever 3 1 Gastroenteritis 3 1 Rhinitis 3 1 Arthritis 2 1 Ecchymosis 2 0 Malaise 2 0 Neck Pain 2 0 Paresthesia 2 1 Vertigo 2 1 *Incidence 2% or greater in AZILECT 1 mg group and numerically more frequent than in placebo group There were no significant differences in the safety profile based on age or gender.
Adjunct Use of AZILECT AZILECT was studied as an adjunct therapy without levodopa (Study 2), or as an adjunct therapy to levodopa, with some patients also taking dopamine agonists, COMT inhibitors, anticholinergics, or amantadine (Study 3 and Study 4). In Study 2, approximately 8% of the 162 patients treated with AZILECT discontinued treatment due to adverse reactions compared to 4% of the 164 patients who received placebo. Adverse reactions that led to the discontinuation of more than one patient were nausea and dizziness.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Meperidine: Risk of serotonin syndrome ( 4 , 7.1 ) Dextromethorphan: Risk of psychosis or bizarre behavior ( 4 , 7.2 ) MAO inhibitors: Risk of non-selective MAO inhibition and hypertensive crisis ( 4 , 7.3 )
7.1Meperidine Serious, sometimes fatal reactions have been precipitated with concomitant use of meperidine (e.g., Demerol and other tradenames) and MAO inhibitors including selective MAO-B inhibitors [see Contraindications ( 4 )] .
7.2Dextromethorphan The concomitant use of AZILECT and dextromethorphan was not allowed in clinical studies. The combination of MAO inhibitors and dextromethorphan has been reported to cause brief episodes of psychosis or bizarre behavior. Therefore, in view of AZILECT’s MAO inhibitory activity, dextromethorphan is contraindicated for use with AZILECT [see Contraindications ( 4 )] .
7.3MAO Inhibitors AZILECT is contraindicated for use with other MAO inhibitors because of the increased risk of nonselective MAO inhibition that may lead to a hypertensive crisis [see Contraindications ( 4 )] .
7.4Sympathomimetic Medications The concomitant use of AZILECT and sympathomimetic medications was not allowed in clinical studies. Severe hypertensive reactions have followed the administration of sympathomimetics and nonselective MAO inhibitors. Hypertensive crisis has been reported in patients taking the recommended dose of AZILECT and sympathomimetic medications.
Severe hypertension has been reported in patients taking the recommended dose of AZILECT and ophthalmic drops containing sympathomimetic medications. Because AZILECT is a selective MAOI, hypertensive reactions are not ordinarily expected with the concomitant use of sympathomimetic medications. Nevertheless, caution should be exercised when concomitantly using recommended doses of AZILECT with any sympathomimetic medications including nasal, oral, and ophthalmic decongestants and cold remedies.
7.5Antidepressants Concomitant use of AZILECT with one of many classes of antidepressants (e.g., SSRIs, SNRIs, triazolopyridine, tricyclic, or tetracyclic antidepressants) is not recommended [see Warnings and Precautions ( 5.2 ) and Clinical Pharmacology ( 12.3 )] . Concomitant use of AZILECT and MAO inhibitors is contraindicated [see Contraindications ( 4 )].
7.6Ciprofloxacin or Other CYP1A2 Inhibitors Rasagiline plasma concentrations may increase up to 2 fold in patients using concomitant ciprofloxacin and other CYP1A2 inhibitors. This could result in increased adverse events. Patients taking concomitant ciprofloxacin or other CYP1A2 inhibitors should not exceed a dose of AZILECT 0.5 mg once daily [see Warnings and Precautions ( 5.4 ) and Clinical Pharmacology ( 12.3 )] .
7.7Tyramine/Rasagiline Interaction MAO in the gastrointestinal tract and liver (primarily type A) provides protection from exogenous amines (e.g., tyramine) that have the capacity, if absorbed intact, to cause a tyramine reaction with hypertension including clinical syndromes referred to as hypertensive urgency, crisis, or emergency. Foods and medications containing large amounts of exogenous amines (e.g., from fermented cheese, herring, over-the-counter cough/cold medications) may cause release of norepinephrine resulting in a rise in systemic blood pressure.
Results of a special tyramine challenge study indicate that rasagiline is selective for MAO-B at recommended doses and can be used without dietary tyramine restriction. However, certain foods may contain very high amounts (i.e., 150 mg or greater) of tyramine and could potentially cause a hypertensive reaction in individual patients taking AZILECT due to increased sensitivity to tyramine. Selectivity for inhibiting MAO-B diminishes in a dose-related manner as the dose is progressively increased above the recommended daily doses.
There were no cases of hypertensive crisis in the clinical development program associated with 1 mg daily AZILECT treatment, in which most patients did not follow dietary tyramine r…
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, may cause fetal harm. ( 8.1 )
8.1Pregnancy Risk Summary There are no adequate data on the developmental risks associated with the use of AZILECT in pregnant women. In animal studies, oral administration of rasagiline to rats during gestation and lactation resulted in decreased survival and reduced body weight in the offspring at doses similar to those used clinically. When administered to pregnant animals in combination with levodopa/carbidopa, there were increased incidences of fetal skeletal variations in rats and increases in embryofetal death and cardiovascular abnormalities in rabbits [see Data] .
In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. The background risks of major birth defects and miscarriage for the indicated population is unknown. Data Animal Data In a combined mating/fertility and embryofetal development study in pregnant rats, no effect on embryofetal development was observed at oral doses up to 3 mg/kg/day (approximately 30 times the plasma exposure (AUC) in humans at the maximum recommended human dose [MRHD, 1 mg/day]).
In pregnant rabbits administered rasagiline throughout the period of organogenesis at oral doses of up to 36 mg/kg/day, no developmental toxicity was observed. At the highest dose tested, the plasma AUC was approximately 800 times that in humans at the MRHD. In pregnant rats administered rasagiline (0, 0.1, 0.3, 1 mg/kg/day) orally during gestation and lactation, offspring survival was decreased and offspring body weight was reduced at 0.3 mg/kg/day and 1 mg/kg/day (10 and 16 times the plasma AUC in humans at the MRHD).
The no-effect dose (0.1 mg/kg) for adverse developmental effects is similar to the MRHD on a body surface area (mg/m 2 ) basis. The effect of rasagiline on physical and behavioral development was not adequately assessed in this study. Rasagiline may be given as an adjunct therapy to levodopa/carbidopa treatment.
In pregnant rats administered rasagiline (0, 0.1, 0.3, 1 mg/kg/day) and levodopa/carbidopa (80/20 mg/kg/day) (alone and in combination) orally throughout the period of organogenesis, there was an increased incidence of fetal skeletal variations in fetuses from rats treated with rasagiline in combination with levodopa/carbidopa at 1/80/20 mg/kg/day (approximately 8 times the rasagiline plasma AUC in humans at the MRHD and similar to the MRHD of levodopa/carbidopa [800/200 mg/day] on a mg/m 2 basis). In pregnant rabbits dosed orally throughout the period of organogenesis with rasagiline alone (3 mg/kg) or in combination with levodopa/carbidopa (rasagiline: 0.1, 0.6, 1.2 mg/kg, levodopa/carbidopa: 80/20 mg/kg/day), an increase in embryofetal death was noted at rasagiline doses of 0.6 and 1.2 mg/kg/day when administered in combination with levodopa/carbidopa (approximately 7 and 13 times, respectively, the rasagiline plasma AUC in humans at the MRHD).
There was an increase in cardiovascular abnormalities with levodopa/carbidopa alone (similar to the MRHD on a mg/m 2 basis) and to a greater extent when rasagiline (at all doses; 1-13 times the rasagiline plasma AUC in humans at the MRHD) was administered in combination with levodopa/carbidopa.
8.2Lactation Risk Summary There are no data on the presence of rasagiline in human milk or the effects on the breastfed infant. In rats, rasagiline was shown to inhibit prolactin secretion. The clinical relevance in humans is unknown, and there are no data on the effects of rasagiline on prolactin secretion or milk production in humans.
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for AZILECT and any potential adverse effects on the breastfed infant from AZILECT or from the underlying maternal condition.

In pregnant rats administered rasagiline (0, 0.1, 0.3, 1 mg/kg/day) and levodopa/carbidopa (80/20 mg/kg/day) (alone and in combination) orally throughout the period of organogenesis, there was an increased incidence of fetal skeletal variations in fetuses from rats treated with rasagiline in combination with levodopa/carbidopa at 1/80/20 mg/kg/day (approximately 8 times the rasagiline plasma AUC in humans at the MRHD and similar to the MRHD of levodopa/carbidopa [800/200 mg/day] on a mg/m 2 basis). In pregnant rabbits dosed orally throughout the period of organogenesis with rasagiline alone (3 mg/kg) or in combination with levodopa/carbidopa (rasagiline: 0.1, 0.6, 1.2 mg/kg, levodopa/carbidopa: 80/20 mg/kg/day), an increase in embryofetal death was noted at rasagiline doses of 0.6 and 1.2 mg/kg/day when administered in combination with levodopa/carbidopa (approximately 7 and 13 times, respectively, the rasagiline plasma AUC in humans at the MRHD).
There was an increase in cardiovascular abnormalities with levodopa/carbidopa alone (similar to the MRHD on a mg/m 2 basis) and to a greater extent when rasagiline (at all doses; 1-13 times the rasagiline plasma AUC in humans at the MRHD) was administered in combination with levodopa/carbidopa.

🆘 Overdosage ▾
10 OVERDOSAGE In a dose escalation study in patients on chronic levodopa therapy treated with 10 mg of AZILECT there were three reports of cardiovascular side effects (including hypertension and postural hypotension) which resolved following treatment discontinuation. Although no cases of overdose have been observed with AZILECT during the clinical development program, the following description of presenting symptoms and clinical course is based upon overdose descriptions of nonselective MAO inhibitors. The signs and symptoms of nonselective MAOI overdose may not appear immediately.
Delays of up to 12 hours after ingestion of drug and the appearance of signs may occur. The peak intensity of the syndrome may not be reached until for a day following the overdose. Death has been reported following overdose; therefore, immediate hospitalization, with continuous patient observation and monitoring for at least two days following the ingestion of such drugs in overdose, is strongly recommended.
The severity of the clinical signs and symptoms of MAOI overdose varies and may be related to the amount of drug consumed. The central nervous and cardiovascular systems are prominently involved. Signs and symptoms of MAOI overdose may include: drowsiness, dizziness, faintness, irritability, hyperactivity, agitation, severe headache, hallucinations, trismus, opisthotonos, convulsions, and coma; rapid and irregular pulse, hypertension, hypotension and vascular collapse; precordial pain, respiratory depression and failure, hyperpyrexia, diaphoresis, and cool, clammy skin.
There is no specific antidote for AZILECT overdose. The following suggestions are offered based upon the assumption that AZILECT overdose may be modeled after nonselective MAO inhibitor poisoning. Treatment of overdose with nonselective MAO inhibitors is symptomatic and supportive.
Respiration should be supported by appropriate measures, including management of the airway, use of supplemental oxygen, and mechanical ventilatory assistance, as required. Body temperature should be monitored closely. Intensive management of hyperpyrexia may be required.
Maintenance of fluid and electrolyte balance is essential. For this reason, in cases of overdose with AZILECT, dietary tyramine restriction should be observed for several weeks to reduce the risk of hypertensive tyramine reaction. A poison control center should be called for the most current treatment guidelines.
A postmarketing report described a single patient who developed a nonfatal serotonin syndrome after ingesting 100 mg of AZILECT in a suicide attempt. Another patient who was treated in error with 4 mg AZILECT daily and tramadol also developed a serotonin syndrome. One patient who was treated in error with 3 mg AZILECT daily experienced alternating episodes of vascular fluctuations consisting of hypertension and orthostatic hypotension.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action AZILECT is a selective, irreversible MAO-B inhibitor indicated for the treatment of idiopathic Parkinson’s disease. The results of a clinical trial designed to examine the effects of AZILECT on blood pressure when it is administered with increasing doses of tyramine indicates the functional selectivity can be incomplete when healthy subjects ingest large amounts of tyramine while receiving recommended doses of AZILECT. The selectivity for inhibiting MAO-B diminishes in a dose-related manner.
MAO, a flavin-containing enzyme, is classified into two major molecular species, A and B, and is localized in mitochondrial membranes throughout the body in nerve terminals, brain, liver and intestinal mucosa. MAO regulates the metabolic degradation of catecholamines and serotonin in the CNS and peripheral tissues. MAO-B is the major form in the human brain.
In ex vivo animal studies in brain, liver, and intestinal tissues, rasagiline was shown to be a potent, irreversible monoamine oxidase type B (MAO-B) selective inhibitor. Rasagiline at the recommended therapeutic dose was also shown to be a potent and irreversible inhibitor of MAO-B in platelets. The precise mechanisms of action of rasagiline are unknown.
One mechanism is believed to be related to its MAO-B inhibitory activity, which causes an increase in extracellular levels of dopamine in the striatum. The elevated dopamine level and subsequent increased dopaminergic activity are likely to mediate rasagiline’s beneficial effects seen in models of dopaminergic motor dysfunction.
12.2Pharmacodynamics Tyramine Challenge Test Results of a tyramine challenge study indicate that rasagiline at recommended doses is relatively selective for inhibiting MAO-B and can be used without dietary tyramine restriction. However, certain foods (e.g., aged cheeses, such as Stilton cheese) may contain very high amounts of tyramine (i.e., 150 mg or greater) and could potentially cause severe hypertension caused by tyramine interaction in patients taking AZILECT due to mild increased sensitivity to tyramine at recommended doses.
Relative selectivity of AZILECT for inhibiting MAO-B diminished in a dose-related manner as the dose progressively increased above the highest recommended daily dose (1 mg) [ see Warnings and Precautions ( 5.1 ) and Drug Interactions ( 7.7 ) ] . Platelet MAO Activity in Clinical Studies Studies in healthy subjects and in Parkinson’s disease patients have shown that rasagiline inhibits platelet MAO-B irreversibly. The inhibition lasts at least 1 week after last dose.
Almost 25-35% MAO-B inhibition was achieved after a single rasagiline dose of 1 mg/day and more than 55% of MAO-B inhibition was achieved after a single rasagiline dose of 2 mg/day. Over 90% inhibition was achieved 3 days after rasagiline daily dosing at 2 mg/day and this inhibition level was maintained 3 days postdose. Multiple doses of rasagiline of 0.5, 1, and 2 mg per day resulted in complete MAO-B inhibition.
12.3Pharmacokinetics Rasagiline in the range of 1-6 mg demonstrated a more than proportional increase in AUC, while Cmax was dose proportional. Rasagiline mean steady-state half life is 3 hours but there is no correlation of pharmacokinetics with its pharmacological effect because of its irreversible inhibition of MAO-B. Absorption Rasagiline is rapidly absorbed, reaching peak plasma concentration (Cmax) in approximately 1 hour.
The absolute bioavailability of rasagiline is about 36%. Food does not affect the Tmax of rasagiline, although Cmax and exposure (AUC) are decreased by approximately 60% and 20%, respectively, when the drug is taken with a high fat meal. Because AUC is not significantly affected, AZILECT can be administered with or without food.
Distribution The mean volume of distribution at steady-state is 87 L, indicating that the tissue binding of rasagiline is in excess of plasma protein binding. Plasma protein binding ranges from 88-94% with mean…

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Hypertension Advise patients that treatment with recommended doses of AZILECT may be associated with elevations of blood pressure. Tell patients who experience elevation of blood pressure while taking AZILECT to contact their healthcare provider. The risk of using higher than recommended daily doses of AZILECT should be explained, and a brief description of the tyramine associated hypertensive reaction provided.
Advise patients to avoid certain foods (e.g., aged cheese) containing a very large amount of tyramine while taking recommended doses of AZILECT because of the potential for large increases in blood pressure. If patients eat foods very rich in tyramine and do not feel well soon after eating, they should contact their healthcare provider [see Warnings and Precautions ( 5.1 )] . Serotonin Syndrome Tell patients to inform their physician if they are taking, or planning to take, any prescription or over-the-counter drugs, especially antidepressants and over-the-counter cold medications, since there is a potential for interaction with AZILECT.
Because patients should not use meperidine or certain other analgesics with AZILECT, they should contact their healthcare provider before taking analgesics [see Contraindications ( 4 ) and Warnings and Precautions ( 5.2 )]. Falling Asleep During Activities of Daily Living and Somnolence Advise and alert patients about the potential for sedating effects associated with AZILECT and other dopaminergic medications, including somnolence and particularly to the possibility of falling asleep while engaged in activities of daily living.
Because somnolence can be a frequent adverse reaction with potentially serious consequences, patients should neither drive a car nor engage in other potentially dangerous activities until they have gained sufficient experience with AZILECT and other dopaminergic medications to gauge whether or not it affects their mental and/or motor performance adversely. Advise patients that if increased somnolence or new episodes of falling asleep during activities of daily living (e.g., watching television, passenger in a car, etc.) are experienced at any time during treatment, they should not drive or participate in potentially dangerous activities until they have contacted their physician.
Patients should not drive, operate machinery, or work at heights during treatment if they have previously experienced somnolence and/or have fallen asleep without warning prior to use of AZILECT. Because of possible additive effects, advise patients to exercise caution when patients are taking other sedating medications, alcohol, or other central nervous system depressants (e.g., benzodiazepines, antipsychotics, antidepressants) in combination with AZILECT or when taking concomitant medications that increase plasma levels of rasagiline (e.g., ciprofloxacin) [see Warnings and Precautions ( 5.3 )] .
Ciprofloxacin or Other CYP1A2 Inhibitors Inform patients that they should contact their healthcare provider of AZILECT if they take ciprofloxacin or a similar drug that could increase blood levels of rasagiline because of the need to adjust the dose of AZILECT [see Dosage and Administration ( 2.2 ) and Warnings and Precautions ( 5.4 )]. Hepatic Impairment Tell patients who have hepatic problems to contact their healthcare provider regarding possible changes in AZILECT dosing [see Warnings and Precautions ( 5.5 )] . Hypotension / Orthostatic Hypotension Patients should be advised that they may develop orthostatic hypotension with or without symptoms such as dizziness, nausea, syncope, and sometimes sweating.
Hypotension and/or orthostatic symptoms may occur more frequently during initial therapy or with an increase in dose at any time (cases have been seen after weeks of treatment). Accordingly, patients should be cautioned against standing up rapidly after sitting or lying down, especially if they have been doing so for prolonged periods, and especially, at th…
