The test is performed by administering a progestogen, such as progesterone either as an intramuscular injection or oral medroxyprogesterone acetate (Provera). If the patient has sufficient serum estradiol (greater than 50 pg/mL), withdrawal bleeding should occur 2–7 days after the progestin is withdrawn, indicating that the patient's ...
Medroxyprogesterone acetate (MPA), also known as depot medroxyprogesterone acetate (DMPA) in injectable form and sold under the brand name Depo-Provera among others, is a hormonal medication of the progestin type. [10] [4] It is used as a method of birth control and as a part of menopausal hormone therapy.
Medroxyprogesterone acetate: 17α-Acetoxy-6α-methylprogesterone Megestrol acetate: 17α-Acetoxy-6-methyl-6-dehydroprogesterone Melengestrol acetate: 17α-Acetoxy-16-methylene-6-methyl-6-dehydroprogesterone Methenmadinone acetate: 17α-Acetoxy-16-methylene-6-dehydroprogesterone Osaterone acetate: 17α-Acetoxy-6-chloro-2-oxa-6-dehydroprogesterone
With 20 years of use, breast cancer incidence is about 1.5-fold higher with estrogen alone and about 2.5-fold higher with estrogen plus progestogen therapy relative to non-use. [151] The increase in breast cancer risk with estrogen and progestogen therapy was shown to be causal with conjugated estrogens plus medroxyprogesterone acetate in the ...
Compared to MPA, medroxyprogesterone is over two orders of magnitude less potent as a progestogen. [8] Medroxyprogesterone is also notable in that it is a minor metabolite of MPA. [9] In addition to its progestagenic activity, medroxyprogesterone is a weak antiandrogen in vitro on human androgen receptor. [10]
Medroxyprogesterone acetate (Amen, Curretab, Cycrin, Provera) – 2.5 mg, 5 mg, 10 mg Megestrol acetate (Megace) – 20 mg, 40 mg – approved specifically for the treatment of breast and endometrial cancer [ 46 ] and for the treatment of anorexia , cachexia , and weight loss in patients with AIDS Tooltip acquired immunodeficiency syndrome [ 47 ]
Vaginal ring use can include additional side-effects including vaginal irritation and vaginal discharge. Contraceptive skin patch use can also include a side-effect of skin irritation around the patch site. [39] Breakthrough bleeding within the first 3–6 months is generally not harmful and often resolves with persistent use. [35]
Major examples of progestins include the 17α-hydroxyprogesterone derivative medroxyprogesterone acetate and the 19-nortestosterone derivative norethisterone. The progestins are structural analogues of progesterone and have progestogenic activity similarly, but differ from progesterone in their pharmacological properties in various ways. [5]
