I am on prevacid substitute which works very juch like comantidine does according,to the article at ncbi. It blocks or rather reduces acid formation in the stomach (other ulcer meds work to neutralize acid already produced)
I’ll have to research whether Prevacid has same anti-cancer abilities or not.
It’s not the acid reducing effect that makes Cimetidine anticancer, it’s because of its affect on regulatory T-cells.
Treg cells are immunosuppressive and generally suppress or downregulate induction and proliferation of effector T cells. Cimetidine interferes with Treg cells so the effector T-cells can be fully unleashed. It’s unlikely Prevacid would have similar effect.
