NTZ has shown experimental activity against a number of cancers. This recently published paper demonstrated notable NZT activity against PC mets in an animal model. Don’t try this at home but perhaps worth keeping an eye on. An excerpt with link to full paper below:
Findings in this study present nitazoxanide (NTZ), a drug currently approved for treating parasitic and viral infections [37, 38], as a potential therapeutic agent for treating PCa bone metastasis. The direct evidence for this conclusion came from the animal experiments, where NTZ treatment drastically suppressed the formation of bone metastases in an established mouse model, i.e., of KLF5K369Q-induced bone metastasis (Figs. 2 and 3). The inhibition of bone metastasis was effective in both the preventive and therapeutic modes, as similar efficacies were observed when NTZ was administered at the same time of cell inoculation (Fig. 2) or one week after (Fig. 3).
