Hydroxyprogesterone caproate is a synthetic, steroidal progestin that is similar to medroxyprogesterone acetate and megestrol acetate. It is an ester derivative hydroxyprogesterone formed from caproic acid (hexanoic acid).

Hydroxyprogesterone caproate was previously marketed under the trade name Delalutin by Squibb, which was approved by the U.S. Food and Drug Administration (FDA) in 1956 and withdrawn from marketing in 1999.

The US FDA approved Makena from KV Pharmaceutical (previously named as Gestiva) on February 4, 2011 for prevention ofpreterm delivery in women with a history of preterm delivery, sparking a pricing controversy.

In these women, if the transvaginal ultrasound cervical length shortens to <25 mm at < 24 weeks, cervical cerclage may be offered. In the 2013 study the guideline recommendation is based on by there was also a significant decrease of neonatal morbidity including lower rates ofnecrotizing enterocolitis (0 in treatment group vs 4 in control), intraventricular hemorrhage (4 in the treatment group compared with 8 in the control for relative risk of 0.25), and need for supplemental oxygen (14% in treatment group vs 24% in placebo for relative risk of 0.42). Furthermore, this study contained 463 patients, 310 of whom received injection. Of these patients, 9 had infants with congenital malformations (2%), but there was no consistent pattern and none involved internal organs.
