4.2 Drug Indication

Hydroxyprogesterone caproate is indicated for the prevention of spontaneous preterm births in singleton pregnancies in women who have previously had a spontaneous preterm birth. (1)


FDA Label


5 Pharmacology and Biochemistry
5.1 Pharmacology

No specific pharmacodynamic studies have been performed to assess hydroxyprogesterone caproate injections. (4) However, the mechanism of action is likely related to increased interaction between progesterone and progesterone receptors. (5)


5.2 MeSH Pharmacological Classification

Progestins

Compounds that interact with PROGESTERONE RECEPTORS in target tissues to bring about the effects similar to those of PROGESTERONE. Primary actions of progestins, including natural and synthetic steroids, are on the UTERUS and the MAMMARY GLAND in preparation for and in maintenance of PREGNANCY. (See all compounds classified as Progestins.)


Estrogen Antagonists

Compounds which inhibit or antagonize the action or biosynthesis of estrogenic compounds. (See all compounds classified as Estrogen Antagonists.)


5.3 FDA Pharmacological Classification
5.3.1 Pharmacological Classes
Progestin [EPC]; Progesterone Congeners [CS]
5.4 Absorption, Distribution and Excretion

Absorption

Absorption of 17-hydroxyprogesteron caproate is slow, occurring over a long period of time. (3)


Route of Elimination

Following intramuscular injection, approximately 50% of hydroxyprogesterone caproate metabolites are eliminated in the feces, while approximately 30% of metabolites are eliminated in the urine. (3)


Volume of Distribution

Hydroxyprogesterone caproate has a high volume of distribution. (3)


Clearance

Clearance is highly variable from patient to patient. (3)


5.5 Metabolism/Metabolites

The main enzymes involved in metabolism of hydroxyprogesterone caproate are cytochrome P450 (CYP) 3A4 and to a lesser extent CYP3A5. (3)


5.6 Biological Half-Life

Half-life = 16 days (6 days). (3)


5.7 Mechanism of Action

The mechanism by which progesterone prevents preterm birth is not well understood, but many pathways are likely involved. (1) Progesterone plays a vital role in regulation of the female reproductive system and is important for successful implantation of the embryo and maintenance of pregnancy. It acts by binding to progesterone receptors in the uterus, ovaries, breasts and in the central nervous system. These receptors exist in 2 isoforms, PR-A and PR-B. Progesterone binding to these receptors ultimately leads to regulation of gene transcription. (2) This results in an anti-inflammatory effect which blunts the proinflammatory state that occurs with initiation of labor, and maintains uterine queiscence by stabilizing progesterone acting on the myometrium. (2)
