Studies of this formulation have been published.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. 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.As of April 2022, a vaginal ring containing E2/P4 (developmental code names DARE-HRT1 and JNP-0201) is under development for use in menopausal hormone therapy.
