Kaletra Oral Solution and Sufenta

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.

Ritonavir can increase the blood levels and effects of SUFentanil. This may increase the risk of side effects such as excessive sedation, slow heart rate, shallow or difficult breathing, and/or shortness of breath. You may need a dose adjustment to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

MONITOR: Coadministration with potent inhibitors of CYP450 3A4 may increase the plasma concentrations of sufentanil, which is primarily metabolized by the isoenzyme. Increased sufentanil concentrations may enhance or prolong pharmacologic effects and potentiate the risk of central nervous system and respiratory depression. In six healthy volunteers, pretreatment with erythromycin (500 mg twice a day for 7 days) had no significant effects on the pharmacokinetics of sufentanil (3 mcg/kg single IV dose) relative to placebo in the nine hours following administration. However, in vitro data suggest that other potent CYP450 3A4 inhibitors (e.g., itraconazole, ketoconazole, ritonavir) may interfere with the metabolism of sufentanil.

MANAGEMENT: Patients receiving sufentanil with potent CYP450 3A4 inhibitors should be carefully monitored for excessive central nervous system and respiratory depression, and dosage adjustments made accordingly if necessary.
