Sitalopram ve Protriptilin etkileşimi

Serotonin Syndrome: Increased risk when co-administered with other serotonergic agents, but also when taken alone.

If concomitant use of Citalopram Capsules with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms.

If serotonin syndrome occurs, consider discontinuation of Citalopram Capsules and/or concomitant serotonergic drugs [see Dosage and Administration ( 2.1 , 2.4 ), Warnings and Precautions ( 5.3 )] .

The risk is increased with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, meperidine, methadone, tryptophan, buspirone, amphetamines, and St.

If it occurs, discontinue Citalopram Capsules and serotonergic agents and initiate supportive treatment ( 4 , 5.3 , 7 )

Anyone considering the use of protriptyline hydrochloride or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need.

Tachycardia and postural hypotension may occur more frequently with protriptyline than with other antidepressant drugs.

Nevertheless, caution is indicated in the coadministration of TCAs with any of the SSRIs and also in switching from one class to the other.

The drugs that inhibit cytochrome P450 2D6 include some that are not metabolized by the enzyme (quinidine; cimetidine) and many that are substrates for P450 2D6 (many other antidepressants, phenothiazines, and the Type 1C antiarrhythmics, propafenone and flecainide).

While all the selective serotonin reuptake inhibitors (SSRIs), e.g., fluoxetine, sertraline, and paroxetine, inhibit P450 2D6, they may vary in the extent of inhibition.
