Tương tác
Concurrent use with moderate and strong CYP3A4 and P-glycoprotein (P-gp) inducers (e.g. carbamazepine, phenobarbital, phenytoin, rifampicin) may decrease the serum concentration of darolutamide. May increase the serum concentration of breast cancer resistance protein (BCRP), organic anion transporting polypeptides (OATP) 1B1 or 1B3 substrates (e.g. rosuvastatin, atorvastatin, pitavastatin, fluvastatin, methotrexate, sulfasalazine). May increase the risk of adverse reactions with combined P-gp and strong CYP3A4 inhibitor (e.g. itraconazole). May increase the risk of QT prolongation with QT-prolonging drugs such as antiarrhythmic agents (e.g. disopyramide, quinidine, sotalol, amiodarone, ibutilide, dofetilide), moxifloxacin, methadone, antipsychotics (e.g. haloperidol).
Tương tác với thức ăn
May decrease serum concentration with St. John's wort. Increased bioavailability with food.
Tác dụng
Description: Darolutamide is a non-steroidal competitive androgen receptor inhibitor that binds with high affinity directly to the receptor ligand-binding domain. It also inhibits androgen receptor nuclear translocation and androgen receptor-mediated transcription. The inhibition of androgen receptor causes reduced prostate tumour cell proliferation and increased apoptosis, resulting in a decrease in tumour volume.
Pharmacokinetics:
Absorption: Increased bioavailability by 2- to 2.5-fold when given with food. Bioavailability: Approx 30% (after 300 mg dose under fasted conditions). Time to peak plasma concentration: Approx 4 hours.
Distribution: Widely distributed throughout the body. Plasma protein binding: 92% (darolutamide); 99.8% (keto-darolutamide); mainly to albumin.
Metabolism: Mainly metabolised via oxidative metabolism by CYP3A4, also via direct glucuronidation by UGT1A9 and UGT1A1; keto-darolutamide is the active major metabolite.
Excretion: Via urine (63.4%; approx 7% as unchanged drug); faeces (32.4%; approx 30% as unchanged drug). Elimination half-life: Approx 20 hours (darolutamide; keto-darolutamide).
