Drug-drug interactions in metastatic hormone-sensitive prostate cancer (mHSPC): practical considerations for treating men with androgen receptor pathway inhibitors and common medications in this stage

Introduction New androgen receptor pathway inhibitors (ARPIs) are an essential part of the treatment strategy for patients with metastatic hormone-sensitive prostate cancer (mHSPC). Despite the good tolerability of ARPIs, after treatment is started, drug-drug interactions (DDIs) between these and other medications frequently taken by these patients may appear. DDIs may reduce the therapeutic effect of both and lead to increased adverse events. DDIs should be carefully assessed before an ARPI is started.
