Medical uses
EBB/DHPA is used as a once-a-month combined injectable contraceptive to prevent pregnancy in women.[1][2][3]
Available forms
EBB/DHPA contains 10 mg estradiol benzoate butyrate (EBB), an estrogen, and 150 mg algestone acetophenide (dihydroxyprogesterone acetophenide; DHPA), a progestin.[2][3]
Pharmacology
Pharmacodynamics
EBB/DHPA has been said to have relatively weak estrogenic activity and has been described as "progestogen-dominant".[1]
Pharmacokinetics
EBB is said to have a shorter duration than estradiol enantate of about 3 weeks.[7] EBB/DHPA was developed because it was thought that the duration of EBB would be more suitable for use as a once-monthly combined injectable contraceptive than estradiol enantate in estradiol enantate/algestone acetophenide.[7]
