Buckleys Mixture and Tavalisse

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.

Fostamatinib may increase the blood levels and effects of dextromethorphan. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. 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 fostamatinib may increase the plasma concentrations of drugs that are substrates of the CYP450 3A4 isoenzyme and/or P-glycoprotein (P-gp) transporter. The proposed mechanism is decreased clearance in the intestine and/or liver due to inhibition of CYP450 3A4-mediated metabolism and P-gp-mediated efflux by fostamatinib. According to the product labeling, administration of a single 40 mg dose of the CYP450 3A4 substrate simvastatin with fostamatinib 100 mg twice daily increased simvastatin peak plasma concentration (Cmax) and systemic exposure (AUC) by 113% and 64%, respectively. In addition, simvastatin acid Cmax increased by 83% and AUC increased by 64%. When the P-gp substrate digoxin (0.25 mg once daily) was administered with fostamatinib (100 mg twice daily), digoxin Cmax and AUC increased by 70% and 37%, respectively.

MANAGEMENT: Caution is advised when fostamatinib is used concurrently with drugs that are known substrates of CYP450 3A4 and/or P-gp, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever fostamatinib is added to or withdrawn from therapy.
