Antipsychotics : lurasidone ↑ lurasidone Co-administration is contraindicated due to potential for serious and/or life-threatening reactions. pimozide ↑ pimozide Co-administration is contraindicated due to potential for serious and/or life-threatening reactions such as cardiac arrhythmias. quetiapine ↑ quetiapine Initiation of PREZISTA with ritonavir in patients…

Sedatives/hypnotics: orally administered midazolam, triazolam ↑ midazolam ↑ triazolam Co-administration is contraindicated due to potential for serious and/or life-threatening reactions such as prolonged or increased sedation or respiratory depression.

…patients taking PREZISTA with ritonavir: Refer to the quetiapine prescribing information for initial dosing and titration of quetiapine. e.g. perphenazine, risperidone, thioridazine ↑ antipsychotics A decrease in the dose of antipsychotics that are metabolized by CYP3A or CYP2D6 may be needed when co-administered with PREZISTA/ritonavir. β-Blockers : e.g. carvedilol,…

Concomitant use of pimozide with paroxetine and other strong CYP 2D6 inhibitors is contraindicated (See PRECAUTIONS – DRUG INTERACTIONS ).

Similarly, protease inhibitor drugs are also inhibitors of CYP 3A4, and thus pimozide is contraindicated in patients receiving protease inhibitors such as ritonavir, saquinovir, indinavir, and nelfinavir.

Since pimozide is partly metabolized via CYP 3A4, it should not be administered concomitantly with inhibitors of this metabolic system, such as azole antifungal agents and protease inhibitor drugs (see CONTRAINDICATIONS ).

Concomitant use of pimozide and paroxetine or other strong CYP 2D6 inhibitors are contraindicated (see CONTRAINDICATIONS ).

CYP 2D6 inhibitors: In healthy subjects, co-administration of pimozide 2 mg (single dose) and paroxetine 60 mg resulted in a 151% increase in pimozide AUC and a 62% increase in pimozide C max compared to pimozide administered alone.
