Procardia XL and Suvorexant

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.

NIFEdipine may increase the blood levels of suvorexant. In some cases, this can increase the risk and/or severity of side effects including excessive drowsiness, motor impairment, amnesia, anxiety, hallucinations, and breathing difficulties (especially if you have a respiratory disorder such as asthma or obstructive sleep apnea). Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. You should avoid the use of alcohol while being treated with suvorexant. Avoid driving or operating hazardous machinery until you know how the medication affects you, and do not exceed the dosage or frequency of use prescribed by your doctor. 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 inhibitors of CYP450 3A4 may increase the plasma concentrations of suvorexant, which is primarily metabolized by the isoenzyme. According to the product labeling, suvorexant peak plasma concentration (Cmax) and systemic exposure (AUC) increased by approximately 1.3- and 2.8-fold, respectively, when coadministered with the potent CYP450 3A4 inhibitor ketoconazole (400 mg). Suvorexant Cmax increased by approximately 1.2-fold and AUC by approximately 2.1-fold when coadministered with the moderate CYP450 3A4 inhibitor diltiazem (240 mg). No data are available for use with other, less potent inhibitors.

MANAGEMENT: Caution is advised if suvorexant is prescribed with inhibitors of CYP450 3A4. Patients should be monitored for excessive sedation and other side effects, and the suvorexant dosage adjusted as necessary.
