Dutasteride and tamsulosin and Gengraf Capsules

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.

CycloSPORINE may increase the blood levels of dutasteride. This can increase the risk of side effects such as impotence, decreased libido, ejaculation disorders, and breast enlargement or tenderness. You may need a dose adjustment or more frequent monitoring by your doctor 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: Based on in vitro data, coadministration with inhibitors of CYP450 3A4 may increase the plasma concentrations of dutasteride, which is metabolized by the isoenzyme. No clinical drug interaction studies have been conducted. However, a population pharmacokinetic analysis found decreased clearance of dutasteride when it is coadministered with the moderate CYP450 3A4 inhibitors, verapamil and diltiazem (37% and 44%, respectively). In contrast, no decrease in dutasteride clearance was seen during coadministration with amlodipine, a calcium channel blocker that is not a CYP450 3A4 inhibitor.

MANAGEMENT: The possibility of prolonged and/or increased pharmacologic effects of dutasteride should be considered during concomitant therapy with CYP450 3A4 inhibitors, particularly potent ones like itraconazole, ketoconazole, posaconazole, voriconazole, conivaptan, nefazodone, cobicistat, delavirdine, protease inhibitors, and ketolide and certain macrolide antibiotics.
