Fluoxymesterone, sold under the brand names Halotestin and Ultandren among others, is a synthetic, orally active androgenic-anabolic steroid (AAS) and a 17α-alkylated derivative of testosterone.While there are legitimate medical uses of fluoxymesterone, it is also abused, leading to the development of analytical techniques by which fluoxymesterone doping can be identified.
This medication is used in men who do not make enough of a natural substance called testosterone. In males, testosterone is responsible for many normal functions, including growth and development of the genitals, muscles, and bones. It also helps cause normal sexual development (puberty) in boys. Fluoxymesterone is similar to the natural testosterone produced by your body. It belongs to a class of drugs known as androgens. It works by affecting many body systems so that the body can develop and function normally.
Fluoxymesterone may also be used in certain adolescent boys to cause puberty in those with delayed puberty.
How Fluoxymesterone Works:
Hormones are chemical substances that are produced by glands in the body, which enter the bloodstream and cause effects in other tissues. For example, the hormone testosterone, made in the testicles and is responsible for male characteristics such as deepening voice and increased body hair. The use of hormone therapy to treat cancer is based on the observation that receptors for specific hormones that are needed for cell growth are on the surface of some tumor cells. Hormone therapy can work by stopping the production of a certain hormone, blocking hormone receptors, or substituting chemically similar agents for the active hormone, which cannot be used by the tumor cell. The different types of hormone therapies are categorized by their function and/or the type of hormone that is effected.
Fluoxymesterone is classified as an androgen. Androgens are hormones such as testosterone and androsterone that produce or stimulate the development of male characteristics. In women, these hormones can be converted into estrogen. Androgens as cancer therapy are used to oppose the activity of estrogen, thereby slowing the growth of cancer.
