Estradiol valerate
In addition to single-drug formulations, oral estradiol valerate is available in combination with the progestin dienogest as a combined oral contraceptive and intramuscular estradiol valerate is marketed in combination with the progestins hydroxyprogesterone caproate and norethisterone enantate as combined injectable contraceptives. Intramuscular estradiol valerate has also been marketed in combination with testosterone enantate, but this formulation has been discontinued. The availability of estradiol valerate-containing products varies throughout the world.
Estradiol/progesterone
Estradiol/progesterone (E2/P4), sold under the brand names Bijuva and Juvenum, is a combined estrogen and progestogen medication which is used in the treatment of menopausal symptoms in postmenopausal women. It contains estradiol, an estrogen, and progesterone, a progestogen, and is available in both oral and intramucular formulations. E2/P4 differs from other estrogen–progestogen formulations in that the sex-hormonal agents used are bioidentical.
