التداخل بين أمانتادين وراساجيلين

Decreasing the levodopa dose may lessen or eliminate this side effect ( 5.7 )

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%).

For this reason, prescribers should monitor patients for drowsiness or sleepiness, because some of the events occur well after initiation of treatment with dopaminergic medication.

In Study 2 where rasagiline was given as an adjunct therapy in patients not taking concomitant levodopa, there were 5 reports of orthostatic hypotension in patients taking rasagiline 1 mg (3.1%) and 1 report in patients taking placebo (0.6%) [see Adverse Reactions ( 6.1 )] .
