Pharmacology

Tibolone possesses a complex pharmacology. Its two major active metabolites, 3α-hydroxytibolone and 3β-hydroxytibolone, act as potent, fully activating agonists of the estrogen receptor (ER), with a high preference for ERα. Tibolone and its metabolite Δ⁴-tibolone act as agonists of the progesterone and androgen receptors,while 3α-hydroxytibolone and 3β-hydroxytibolone, conversely, act as antagonists of these receptors.

Lastly, tibolone, 3α-hydroxytibolone, and 3β-hydroxytibolone act as antagonists of the glucocorticoid and mineralocorticoid receptors, with preference for the mineralocorticoid receptor.Tibolone has tissue-selective estrogenic effects, with desirable effects in bone, the brain, and the vagina, and lack of undesirable action in the endometrium and breasts.

Its tissue selectivity is the result of metabolism, enzyme modulation (e.g., of estrogen sulfatase and estrogen sulfotransferase), and receptor modulation that vary in different target tissues, and differs mechanistically from that of selective estrogen receptor modulators (SERMs) such as tamoxifen, which produce their tissue-selectivity via means of modulation of the ER.

As such, to distinguish it from SERMs, tibolone has been described as a "selective tissue estrogenic activity regulator" (STEAR),and also as a "selective estrogen enzyme modulator" (SEEM).

Adverse effects

A report in September 2009 from Health and Human Services' Agency for Healthcare Research and Quality suggests that tamoxifen, raloxifene, and tibolone used to treat breast cancer significantly reduce invasive breast cancer in midlife and older women, but also increase the risk of adverse side effects.

Tibolone Overdose

Symptoms of overdose include feeling sick or being sick and vaginal bleeding.

If you think you, or someone you care for, might have accidentally taken more than the recommended dose of tibolone or intentional overdose is suspected, contact your local hospital, GP or if in England call 111. In Scotland call NHS 24. In Wales, call NHS Direct Wales. In the case of medical emergencies, always dial 999.

Missed Dose

If you miss a dose, take it as soon as you remember, unless you are more than 12 hours late. If you are more than 12 hours late, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up
