Tamoxifen is the core active ingredient in the drug, but its physical properties are unstable (strongly lipid-soluble, extremely poorly water-soluble), making it difficult to formulate. Tamoxifen citrate is a stable salt form of tamoxifen, which is not only easier to formulate but also improves the drug’s stability and solubility.
Yes, Tamoxifen citrate can be used to treat male breast cancer or gynecomastia.
Both Clomiphene Citrate and Tamoxifen are selective estrogen receptor modulators; they both work by blocking estrogen in certain tissues.
The difference is that Clomiphene Citrate is mainly used to treat female infertility caused by ovulation disorders, while tamoxifen is a core drug for treating positive breast cancer.
