Rasagiline mesylate

Clinical summary

Indications and usage 1 INDICATIONS AND USAGE Rasagiline tablets are indicated for the treatment of Parkinson’s disease (PD). Rasagiline tablets, a monoamine oxidase (MAO)-B inhibitor (MAOI), is indicated for the treatment of Parkinson's disease Dosage and administration 2 DOSAGE AND ADMINISTRATION • Monotherapy: Rasagiline tablets 1 mg once daily ( 2.1 ) • As adjunct without levodopa: Rasagiline tablets 1 mg once daily ( 2.1 ) • As adjunct to levodopa: Rasagiline tablets 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: Rasagiline tablets 0.5 mg once daily ( 2.2, 5.4 ) • Patients with mild hepatic impairment: Rasagiline tablets 0.5 mg once daily. Rasagiline tablets should not be used in patients with moderate or severe hepatic impairment ( 2.3 , 5.5 ) 2.1 General Dosing Recommendations When rasagiline tablets are prescribed as monotherapy or as adjunct therapy in patients not taking levodopa, patients may start rasagiline tablets 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 rasagiline tablets 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 rasagiline tablets are used in combination with levodopa, a reduction of the levodopa dose may be considered, based upon individual response. The recommended doses of rasagiline tablets should not be exceeded because of risk of hypertension [see Warnings and Precautions (5.1)] . 2.2 Patients Taking Ciprofloxacin or Other CYP1A2 Inhibitors Patients taking concomitant ciprofloxacin or other CYP1A2 inhibitors should not exceed a dose of rasagiline tablets 0.5 mg once daily [see Warnings and Precautions ( 5.4 ), Drug Interactions ( 7.6 ), and Clinical Pharmacology ( 12.3 )]. 2.3 Patients with Hepatic Impairment Patients with mild hepatic impairment should not exceed a dose of rasagiline tablets 0.5 mg once daily. Rasagiline tablets 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 )]. 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 ) 5.1 Hypertension Exacerbation of hypertension may occur during treatment with rasagiline. 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 rasagiline. In Study 3, rasagiline (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 rasagiline (2%) compared to placebo (1%). Dietary tyramine restriction is not required during treatment with recommended doses of rasagiline. 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 rasagiline, 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 rasagiline because of the potential for large increases in blood pressure including clinical syndromes referred to as hypertensive urgency, crisis, or emergency. Rasagiline 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. 5.2 Serotonin Syndrome Serotonin syndrome has been reported with concomitant use of an antidepressa
