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.[1] It contains estradiol, an estrogen, and progesterone, a progestogen, and is available in both oral and intramuscular formulations.[1] E2/P4 differs from other estrogen–progestogen formulations in that the sex-hormonal agents used are bioidentical.

Bijuva (formerly TX-001HR/TX-12-001HR) is an oral combination of estradiol (E2), an estrogen, and progesterone (P4), a progestogen, which was developed by TherapeuticsMD and is approved in the United States for the treatment of menopausal symptoms in women.[2][3] It is also under development for the treatment of endometrial hyperplasia in women.[2] The medication contains 2 mg solubilized E2 and 200 mg P4 in each gelatin capsule.[3][1] It is the first combination of E2 and P4 in oral capsule form that has been developed for clinical use.[3] Bijuva is currently in phase III clinical trials for endometrial hyperplasia.[2] The medication was approved by the Food and Drug Administration for the treatment of menopausal symptoms in October 2018.[2][4][1]

E2/P4 is available as an aqueous suspension of E2 and P4 encapsulated in microspheres for use by intramuscular injection once a month under the brand name Juvenum in Mexico.[5][6][7] It was introduced for the treatment and prevention of menopausal symptoms like hot flashes, vulvovaginal symptoms, and osteoporosis in December 2014.[5][6] The combination contains relatively low doses of E2 and P4 (1 mg and 20 mg, respectively) contained within microspheres that results in a slower release of the hormones.[5][6] Studies of this formulation have been published.[8][9]

E2/P4 with 5 mg E2 and 150 to 300 mg P4 encapsulated in microspheres in an aqueous suspension has been studied as a once-a-month combined injectable contraceptive but has not been further developed or introduced for medical use.[10][11][12][13][14] E2/P4 with 5 mg E2 and 100 mg P4 in a macrocrystalline aqueous suspension has also been studied as a once-a-month combined injectable contraceptive, but likewise was not further developed.[15][16]
