التداخل بين أميتريبتيلين وفيلازودون

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

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.

The extent to which SSRITCA interactions may pose clinical problems will depend on the degree of inhibition and the pharmacokinetics of the SSRI involved.

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

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

Drugs Having Clinically Important Interactions With VIIBRYD Table 4: Clinically Important Drug Interactions with VIIBRYD Concomitant Drug Name or Drug Class Clinical Rationale Clinical Recommendation Monoamine Oxidase Inhibitors (MAOIs) The concomitant use of MAOIs and serotonergic drugs including VIIBRYD increases the risk of serotonin syndrome.

If serotonin syndrome occurs, consider discontinuation of VIIBRYD and/or concomitant serotonergic drugs [see Warnings and Precautions ( 5.2 )].

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