I-Toremifene - Ukusetyenziswa, Idosi, Iziphumo Ezingalindelekanga kunye nokunye

Intshayelelo: Yintoni iToremifene?

I-Toremifene liyeza elisetyenziswa kakhulu kunyango lomhlaza webele. Likwiqela lamayeza aziwa ngokuba zii-selective estrogen receptor modulators (SERMs). I-Toremifene isebenza ngokuphazamisana nesenzo se-estrogen emzimbeni, nto leyo enokunceda ukucothisa okanye ukumisa ukukhula kweentlobo ezithile zeethumba zebele ezifuna i-estrogen ukuba ikhule. Ivunyiwe yi-FDA kubasetyhini abasemva kokuya exesheni abanomhlaza webele osasazeka kwi-estrogen receptor.

Ukusetyenziswa kweToremifene

I-Toremifene ivunyiwe kakhulu kunyango lomhlaza webele osasazekayo kubasetyhini abasele beyekile ukuya exesheni. Isebenza ngakumbi kwizigulana ezinomhlaza one-hormone receptor-positive, nto leyo ethetha ukuba iiseli zomhlaza ziyakhula ngenxa ye-estrogen.

Ingaba isebenza kanjani?

I-Toremifene isebenza ngokubophelela kwii-receptor ze-estrogen kwiiseli zomhlaza. Ngamazwi alula, isebenza njenge-"blocker" ethintela i-estrogen ekunamatheleni kwezi receptors. Ekubeni eminye imidla yomhlaza wamabele ifuna i-estrogen ukuze ikhule, ukuvimba le hormone kunokunceda ukunciphisa okanye ukumisa inkqubela yomhlaza. Le ndlela ifana neyezinye ii-SERM, ezinokuthi zivuselele okanye zithintele iziphumo ze-estrogen kwiithishu ezahlukeneyo.

Isisombululo kunye noLawulo

Umlinganiselo oqhelekileyo weToremifene kubantu abadala udla ngokuba yi-60 mg ethathwa ngomlomo kanye ngemini. Kubalulekile ukuthatha amayeza ngexesha elinye yonke imihla ukuze kugcinwe amanqanaba afanayo emzimbeni. IToremifene ayinikwa rhoqo abantwana, njengoko ukhuseleko nempumelelo yayo ebantwaneni ayikaqinisekiswa. Iipilisi kufuneka ziginywe ziphelele ngamanzi kwaye zingathathwa nokutya okanye ngaphandle kokutya.
