In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Consumer:

Consumer information for this minor interaction is not currently available. Some minor drug interactions may not be clinically relevant in all patients. Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.

Professional:

Coadministration with inhibitors of CYP450 3A4 may only modestly increase the plasma concentrations of ziprasidone, as less than 1/3 of ziprasidone metabolic clearance occurs via oxidation mediated by CYP450 3A4. In 14 healthy subjects, coadministration with the potent CYP450 3A4 inhibitor ketoconazole (400 mg orally once a day for 5 days) increased the mean peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of ziprasidone (40 mg single oral dose) by approximately 1/3 compared to placebo. These changes, although statistically significant, were not considered clinically important. There were also no serious adverse events, laboratory or ECG abnormalities, or clinically significant alterations in vital signs throughout the study. Likewise, in 10 healthy subjects, the nonspecific CYP450 inhibitor cimetidine (800 mg orally once a day for 3 days) increased the AUC of ziprasidone (40 mg single oral dose) by just 6% compared to when ziprasidone was administered alone. These findings suggest that ziprasidone dose modifications are unlikely to be necessary in patients receiving potent CYP450 3A4 inhibitors.
