Apalutamide (Erleada)

General information

Class/mechanism: Antiandrogen; androgen receptor inhibitor (ARI). Apalutamide competitively inhibits activity mediated by the androgen receptor (AR) by binding directly to the AR ligand-binding domain, nuclear translocation, DNA binding, and AR-mediated transcription. A metabolite of apalutamide, N-desmethyl apalutamide, also exhibits some AR inhibiting activity, about 1/3 that of apalutamide.
Route: PO
Extravasation: n/a
