التداخل بين ميثامفيتامين وبروتريبتيلين

Serotonin Syndrome: Increased risk when coadministered with serotonergic agents (e.g., SSRIs, SNRIs, triptans), but also during overdosage situations.

If serotonin syndrome occurs, discontinue methamphetamine hydrochloride tablets, USP and the concomitant serotonergic drug(s) [see Warnings and Precautions 5.8].

If concomitant use of methamphetamine with other serotonergic drugs or CYP2D6 inhibitors is clinically warranted, initiate methamphetamine with lower doses, monitor patients for the emergence of serotonin syndrome during drug initiation or titration, and inform patients of the increased risk for serotonin syndrome.

Serotonergic Drugs Clinical Impact: The concomitant use of amphetamines, including methamphetamine hydrochloride tablets, USP , and serotonergic drugs increases the risk of serotonin syndrome.

Tricyclic Antidepressants Clinical Impact: May enhance the activity of tricyclic or sympathomimetic agents causing sustained increases in the concentration of d-amphetamine in the brain; cardiovascular effects can be potentiated.

Drug Interactions When protriptyline is given with anticholinergic agents or sympathomimetic drugs, including epinephrine combined with local anesthetics, close supervision and careful adjustment of dosages are required.
