5630-53-5 High Purity Estrogen Hormone Steroid Powder Tibolone Acetate Livial

Description:

Tibolone Livial/Liviella is used mainly for treatment of endometriosis, as well as hormone replacement

therapy in post-menopausal women. Tibolone is a synthetic steroid hormone drug, which is fairly non-

selective in its binding profile, acting as an agonist mainly at estrogen receptors, with a preference for ER

alpha. Tibolone has similar or greater efficacy compared to older hormone replacement drugs, but shares

a similar side effect profile. It has also been investigated as a possible treatment for female sexual

dysfunction.

Tibolone is a synthetic hormone-type drug which is used mainly for hormone replacement therapy in post-

menopausal women. It is a synthetic steroid that has the same activity as the female sex hormones

estrogen and progesterone and the androgen testosterone. Tibolone helps restore hormonal balance in

the body.

When estrogen levels are low tissues can slowly degenerate, as is experienced during menopause. In

addition, low levels of estrogen can cause distressing symptoms such as hot flushes, night sweats, mood

swings, reduced sex drive and vaginal dryness. Tibolone is broken down into three compounds which act

in a similar way to the natural estrogen and progesterone found in the body. It restores plasma endorphin

level in post-menopausal women and acts centrally to affect the thermo-regulatory system.

Applications:

In itself Tibolone has no biological activity; the effects are produced mainly by the results of the activity of

its metabolites on various tissues. After administration, Tibolone is quickly metabolized into 3¦Á-

hydroxytibolone and 3--hydroxytibolone compounds, which are also present in an inactive, sulfated form.

A third compound, the ¦¤4- isomer is formed from Tibolone directly or from the 3h hydroxymetabolite.

Tibolone has estrogenic effects on bone and vaginal tissue. The ¦¤4-isomer functions as a progestogen in

endometrial tissue, whereas in the brain and liver it has androgenic effects.In breast tissue, Tibolone acts

by strongly inhibiting sulfate activity and weak inhibition of 17¦Á-hydroxysteroid dehydrogenase activity,

which results in blocking the conversion of estrone sulfate to E2.
