Tác dụng
Description: Conjugated oestrogens is a mixture of synthetic sex hormones including estrone sulfate, equilin sulfate, 17α-estradiol, 17α-dihydroequilin and 17β-dihydroequilin. During menopause, these hormones substitutes for oestrogen production and alleviates its symptoms. These hormones also prevent bone loss following menopause or ovariectomy. Medroxyprogesterone reduces the oestrogen-induced risk of endometrial hyperplasia in non-hysterectomised women.
Pharmacokinetics:
Absorption: Conjugated oestrogens: Well absorbed from the gastrointestinal tract. Time to peak plasma concentration: Approx 7 hours (estrone). Medroxyprogesterone: Well absorbed from the gastrointestinal tract. Bioavailability: 0.6-10%. Time to peak plasma concentration: 2-4 hours.
Distribution: Conjugated oestrogens: Widely distributed. Mainly bound to sex hormone binding globulin and albumin. Medroxyprogesterone: Enters breast milk. Plasma protein binding: Approx 90%, mainly to albumin.
Metabolism: Conjugated oestrogens: Estradiol is metabolised in the liver by CYP enzyme system into estrone and estriol; estrone into estradiol and estriol; estriol into estradiol. Undergoes enterohepatic recycling via sulfate and glucuronide conjugation. Medroxyprogesterone: Extensively metabolised in the liver via hydroxylation and conjugation.
Excretion: Conjugated oestrogens: Via urine (mainly as estriol; as estradiol, estrone and conjugates). Elimination half-life: Approx 27 hours (estrone). Medroxyprogesterone: Via urine. Elimination half-life: Approx 16-30 hours.
Bảo quản
Store between 20-25°C.
