Adult: For primary and secondary cases: As ampoule: 250 mg via slow IM inj into the upper outer quadrant of the gluteus maximus or the upper arm, usually given between days 18 and 20 of the menstrual cycle. Endometrial priming with an estrogen (e.g. for 14 days) must be carried out prior to starting treatment.
Intramuscular Reduction of premature birth risk
Adult: In women with singleton pregnancy who have a history of singleton spontaneous premature delivery: As single- or multiple-dose vials: 250 mg once weekly (every 7 days) via slow IM inj over ≥1 minute into the upper outer quadrant of the gluteus maximus. Initiate treatment between 16 weeks, 0 days and 20 weeks, 6 days of gestation. Continue once-weekly administration until week 37 (through 36 weeks, 6 days) of gestation or delivery, whichever comes first.
Intramuscular Recurrent miscarriage
Adult: For prevention of cases associated with proven progesterone deficiency: As ampoule: 250-500 mg weekly during the initial months of pregnancy, or longer if necessary.
Subcutaneous Reduction of premature birth risk
Adult: In women with singleton pregnancy who have a history of singleton spontaneous premature delivery: As auto-injector: 275 mg once weekly (every 7 days) via SC inj into the back of either upper arm. Initiate treatment between 16 weeks, 0 days and 20 weeks, 6 days of gestation. Continue once-weekly administration until week 37 (through 36 weeks, 6 days) of gestation or delivery, whichever comes first.

Significant: Arterial thrombosis, DVT, thromboembolic events, retinal vascular thrombosis; hypersensitivity reactions (e.g. urticaria, pruritus, angioedema); certain degree of fluid retention, reduced glucose tolerance; recurrence of depression (in patients with history of clinical depression); chloasma (particularly in patients with history of chloasma gravidarum). Rarely, benign or malignant liver tumours. Gastrointestinal disorders: Nausea, diarrhoea. General disorders and administration site conditions: Inj site reactions (e.g. pain, swelling, redness, pruritus, nodules).

Skin and subcutaneous tissue disorders: Pruritus, urticaria.
Perform physical and gynaecological exam and take complete medical history before treatment initiation. Monitor blood pressure; blood glucose (in patients with pre-diabetes or diabetes). When used for primary or secondary amenorrhoea: Verify pregnancy status and screen patient for the presence of prolactin-producing pituitary tumour prior to starting therapy; perform breast and pelvic examination, and Papanicolau smear before treatment. Assess for signs or symptoms of fluid retention, jaundice, thromboembolic disorders, or depression.

May enhance clearance and lead to decreased therapeutic efficacy when given with enzyme inducers (e.g. carbamazepine, rifampicin, barbiturates, phenytoin). May interfere with the metabolism of ciclosporin, particularly tissue and plasma concentrations.

Tác dụng
Description: Mechanism of Action: Hydroxyprogesterone caproate, a synthetic progestin, is produced by the esterification of 17α-hydroxyprogesterone (a naturally occurring progesterone) with caproic acid. It has strong progestogenic activity and appears to provide a longer and more potent progestational effect than progesterone. The mechanism of action in reducing the risk of recurrent premature birth is unknown.
Synonym: hydroxyprogesterone hexanoate. Pharmacokinetics: Distribution: Plasma protein binding: Extensive (including albumin and corticosteroid-binding globulins). Metabolism: Extensively metabolised in the liver via reduction, hydroxylation, and conjugation mainly by CYP3A4 and CYP3A5 isoenzymes into conjugated metabolites (including sulfated, glucuronidated, and acetylated products). Excretion: Via urine (IM: approx 30%) and faeces (IM: approx 50%) as conjugated metabolites (predominant) and free steroids. Elimination half-life: Approx 8 days (non-pregnant females); 16.4 ± 3.6 days (IM; pregnant females with singleton pregnancies).
