Protryptylina i Rasagilina: interakcja

May cause serotonin syndrome when used with antidepressants ( 5.2 )

In the postmarketing period, potentially life-threatening serotonin syndrome has been reported in patients treated with antidepressants concomitantly with rasagiline.

Concomitant use of rasagiline with one of many classes of antidepressants (e.g., SSRIs, SNRIs, triazolopyridine, tricyclic or tetracyclic antidepressants) is not recommended [see Drug Interactions ( 7.5 )].

Although a small number of rasagiline-treated patients were concomitantly exposed to antidepressants (tricyclics n=115; SSRIs n=141), the exposure, both in dose and number of subjects, was not adequate to rule out the possibility of an untoward reaction from combining these agents.

Because of the long half-lives of certain antidepressants (e.g., fluoxetine and its active metabolite), at least five weeks (perhaps longer, especially if fluoxetine has been prescribed chronically and/or at higher doses) should elapse between discontinuation of fluoxetine and initiation of rasagiline [see Drug Interactions ( 7.5 )] .

When it is desired to substitute protriptyline for a monoamine oxidase inhibitor, a minimum of 14 days should be allowed to elapse after the latter is discontinued.
