Experts on background and overview · 4 cited mentions
"Tamoxifen has an added benefit of denorexifene acting as an aromatase inhibitor. So tamoxifen is a prodrug for metabolites that have various effects. One of them is a SERM, and the other one is an AI."
"if it takes 2 weeks to wait on labs because your health care provider is slow, then throw in some Nolvadex until you get your labs back... norendoxifen is a metabolite of Nolvadex which acts as a potent aromatase inhibitor."
"40 milligrams tamoxifen and 40 milligrams raloxifene for weeks like this - if not going away, surgery time."
