التداخل بين باروكسيتين وثيوريدازين

Paroxetine HCL CR should not be used in patients receiving medications that can prolong QT interval and are also metabolized by CYP450 2D6,such as thioridazine or pimozide [see Drug Interactions (7),Warnings and Precautions (5.3)].

Concomitant use of pimozide or thioridazine.

Since thioridazine and pimozide given alone produce prolongation of the QTc interval and increase the risk of serious ventricular arrhythmias, the use of Paroxetine HCL CR is contraindicated in combination with thioridazine and pimozide [see Contraindications ( 4 ), Drug Interactions ( 7 ), Clinical Pharmacology ( 12.3 )].

The CYP2D6 inhibitory properties of paroxetine can elevate plasma levels of thioridazine and pimozide.

Reduced cytochrome P450 2D6 isozyme activity drugs that inhibit this isozyme (e.g., fluoxetine and paroxetine) and certain other drugs (e.g., fluvoxamine, propranolol, and pindolol) appear to appreciably inhibit the metabolism of thioridazine.
