Raloxifeno e osteoporose: revisão de um novo modulador seletivo do receptor de estrógeno

Abstract: RESUMORaloxifeno é um modulador seletivo do receptor de estrógeno de segunda geração com ação agonista no osso e sistema cardiovascular e ação antagonista na mama e útero. Sua seletividade tecidual ocorre devido a diversos mecanismos como diferentes receptores de estrógenos, distribuição diferencial destes receptores, diferentes co-fatores protéicos transcricionais e diferente conformação do receptor após ligação de raloxifeno. No osso, raloxifeno aumenta a massa óssea na coluna, fêmur, corpo inteiro, é eficaz… Show more

“…2,3 This drug is a non-steroidal selective estrogen receptor modulator showing estrogenic effects on bone and the cardiovascular system, as well as antiestrogenic effects on breast tissue and endometrium. 4 Furthermore, researchers showed that RH inhibits proliferation of hormone-dependent MCF-7 breast cancer cells and causes cell death via apoptosis and cell cycle arrest. [5][6][7][8] A higher in vitro intestinal permeability and an increase in the oral bioavailability of RH (3.5× higher) was observed for cationic solid lipid nanoparticles.…”

“…Raloxifene hydrochloride (RH; C 28 H 27 NO 4 S.HCl) is a selective estrogen receptor modulator with agonist effect on bones. It is usually administered to women for the prevention and treatment of osteoporosis (Morello, Wurz, DeGregorio, 2003;Kayath, 1999). A 60-mg RH tablet is administered orally, when 60% of the dose is absorbed from the gastrointestinal tract and reaches absolute bioavailability of mere 2% (Morello, Wurz, DeGregorio, 2003).…”
