Anti Aging Estrogen Steroids Powder Tibolone for Female Hormones Medicines CAS 5630-53-5
Assay: 99% min.
Character: White powder.
Usage: pharmaceutical material, Steroid hormone, Anabolin. A synthetic steroid with weak estrogenic, androgenic and progestogenic activity. A pharamceutical used in the treatment of menopausal syndrome.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.It is used mainly for treatment of endometriosis,as well as hormone replacement therapy in post-menopausal women. 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 works by mimicking the activity of the female sex hormones, oestrogen and progesterone. It also has some male hormone (androgen) effects. Tibolone helps to restore the balance of female hormones in women who have a lack of oestrogen; it helps to ease symptoms such as hot flushes and night sweats. You will only be prescribed it if these symptoms seriously interfere with your daily life.
Tibolone is also prescribed to help prevent osteoporosis (bone loss). It is only suitable for women who have been through the menopause, and providing there have been at least 12 months since the last natural period. It is prescribed when other, more preferred, treatments are not suitable.
Although the menopause is a generic physiologic event, its biology is variable and specific to a given individual. Genetically determined distribution and polymorphism of relevant hormone receptors, enzymes, and various cofactors are the biologic mechanisms controlling an individual's clinical response to endogenous and prescribed hormones. Advances in molecular biology have led to the development of newer pharmacologic agents that are tailored to meet specific therapeutic objectives, based on the hormonal biology of relevant organs. Tibolone, an analogue of the progestin, norethynodrel, is a drug with tissue-specific effects on receptors and enzymes that influences the synthesis and metabolism of endogenous estrogen, progesterone, and androgen. This is achieved via the intestinal bioconversion of tibolone into metabolites that have tissue-specific agonistic and/or antagonistic estrogenic (3alpha and 3beta hydroxytibolone) and progestogenic/androgenic (delta4 tibolone) properties.
The postmenopausal synthesis and metabolism of estrogen and androgen are briefly reviewed with particular reference to sex steroid activity in various target organs. On the basis of this hormonal physiology, the clinical utility of tibolone is reviewed as a therapeutic agent for the treatment of the symptomatic menopause. The effects of tibolone on bone health and osteoporosis, cardiovascular disease, the breast, and the endometrium are summarized, and its role in clinical practice is reviewed.
