What is Flutamide?
Definition of Flutamide:Flutamide is a non-steroidal anti-androgen drug substance primarily used for the treatment of prostate cancer.
Mechanism of action of Flutamide:It inhibits the progression of prostate cancer by blocking the binding of androgens to their receptors; its primary active metabolite, α-hydroxyflutamide, exerts anti-androgenic effects within target tissues.
Key Features:Flutamide has no estrogen or progesterone activity and has sufficient therapeutic intensity and clear therapeutic effect.

Pharmaceutical-grade Flutamide has very poor water solubility but is highly lipophilic. It is readily soluble in acetone and chloroform, soluble in methanol, and sparingly soluble in ethanol.
Yes. Although Flutamide is therapeutically effective, it carries a significant risk of liver injury; therefore, regular monitoring of liver function is required during treatment.
Flutamide is a fully synthetic API; it contains no animal-derived materials and poses no risk of TSE/BSE. We can provide a compliance statement upon request.
Our pharmaceutical-grade Flutamide has a purity of ≥99%, with levels of related substances, residual solvents, and heavy metals strictly adhering to pharmacopoeial limits.
It is slightly sensitive to moisture. We use sealed, moisture-proof packaging throughout the process. During transport, it should be protected from light and rain, kept away from heavy pressure, and can be shipped at ambient temperature.
Pharmaceutical-grade Flutamide offers higher purity, stricter impurity controls, and is produced in a GMP-compliant environment, making it suitable for pharmaceutical manufacturing; reagent-grade Flutamide is intended solely for laboratory research and is not suitable for pharmaceutical use.
