Estradiol Benzoate:
Ostrolut (Estradiol Benzoate) is a female sex hormone that regulates many functions in the female organism. This medicine is currently available under the form of tablets in two concentrations - 1 mg and 2 mg, respectively.
Ostrolut (Estradiol Benzoate) is used for the treatment of menopausal symptoms such as vaginal dryness, irritation or burning, or hot flushes - other symptoms that are not listed here may be treated with this medicine as well. Also, this pharmaceutical preparation can be used as a prophylactic agent for the prevention of a medical condition known as osteoporosis in both female and male patients. In some cases, this medicine may also be employed in conjunction with other drugs as part of the treatment for certain types of cancer, both in the case of women and men.
There may be other uses for Ostrolut (Estradiol Benzoate), which are not covered in this leaflet. If you are interested to find out more about the possible uses of this product, it is recommended that you consult with a pharmacist or a specialized physician.
Ostrolut (Estradiol Benzoate) should not be administered to patients that are suffering from any type of disorder involving blood clots, or from circulatory / cardiac disorders. Patients who present an undiagnosed, abnormal vaginal bleeding may not start taking this medicine until they undergo medical examination and receive their physician's approval. Also, patients that have uterine cancer, breast cancer or any type of hormone-dependant cancer may not start a treatment with Ostrolut (Estradiol Benzoate).
Before you start a therapy course with this drug, it is strongly advised to inform your personal physician of any health problems you may be suffering from. In particular, affections such as hypertension, heart disease, angina, high triglyceride / cholesterol levels, renal or hepatic disease, asthma, migraines, epilepsy (or any other disorder involving seizures), diabetes or gallbladder disease should be mentioned, as well as past surgical procedures such as a hysterectomy. Patients suffering from these conditions may require special dosage adjustments or monitoring during the treatment.
Ostrolut (Estradiol Benzoate) may not be administered during pregnancy. Also, for the duration of the therapy you will need to employ an effective, non-hormonal contraceptive method.
Pharmaceutical products based on Estradiol (including Ostrolut (Estradiol Benzoate)) increase the patients' risk of developing an affection known as endometrial hyperplasia. This can be countered by administration of progestin medication. It is recommended that you consult with your doctor for more information.
You need to take Ostrolut (Estradiol Benzoate) exactly as directed by your health care specialist. You may take the tablets with a glass of water or with food to reduce stomach upset; however you may not chew, crush or break the tablets.
While following a treatment course with Ostrolut (Estradiol Benzoate) you will need to undergo regular medical examination, typically on a monthly basis. Also, you will need to regularly self-examine your breasts for the presence of lumps.
Your health care specialist will determine the Ostrolut (Estradiol Benzoate) dosage appropriate for your case by taking into consideration a number of factors, most of which are characteristic to you; as such, your medication dosage is very likely to be different from that of other patients'. Because of that, you should never use the Ostrolut (Estradiol Benzoate) dosage that has been prescribed to another patient - you may not obtain the desired results unless you employ the medication dosage best suited for your situation.
At the same time, your physician will inform you regarding the duration of the Ostrolut (Estradiol Benzoate) therapy and the number of daily intakes. Make sure that you understand all of his or her indications. If you have trouble understanding or remembering any of the dosage directions, you should ask your physician to assist you by providing additional information.
If an overdose with Ostrolut (Estradiol Benzoate) is suspected, immediately contact the nearest hospital as the patient may need emergency medical assistance. The most common signs of an overdose are vaginal bleeding, nausea and vomiting.
In the event that you miss taking one of your Ostrolut (Estradiol Benzoate) doses, take it when you remember before returning to your normal dosing schedule. However, you should skip taking the missed dose if it is almost time for another dose of the medicine. Consult with your physician if you have missed two or more intakes.
Side effects of a treatment with Ostrolut (Estradiol Benzoate) include nausea and vomiting, loss of appetite, swelling of the breasts, sex drive changes, impotence (in the case of men), abnormal vaginal bleeding, vaginal dryness, discomfort or pain, break-through bleeding, menstrual period changes, jaundice, sudden weakness or numbness, breast lumps. These are not all the signs and symptoms that may appear. It is best that you check with your doctor at any point during the course of your therapy if anything unusual occurs.
Although uncommon, allergic reactions to Ostrolut (Estradiol Benzoate) are possible. It is strongly recommended that you cease taking the medicine and contact your personal health care provider if you begin experiencing any of the characteristic symptoms - breathing difficulties, swelling of the throat, lips, tongue or face, rashes and hives.
Ostrolut (Estradiol Benzoate) may interact with Phenobarbital, Phenytoin, Ritonavir, Cimetidine, Carbamazepine, Rifampin, blood thinning agents such as Warfarin or with antibiotics (Clarithromycin, Erythromycin, Ketoconazole or Itraconazole). Also, this product may interact with the herbal remedy St. John's wort. These are not all the possible drug reactions; it is best that you tell your prescriber about any other drugs you are currently taking prior to starting your treatment. In most cases, an adjustment to the medication dosage will ensure the safety of the treatment, reducing the risk of accidental interactions.
Hydroxyprogesterone Caproate:
Ostrolut (Hydroxyprogesterone Caproate) is a progestin indicated to reduce the risk of preterm birth in women with a singleton pregnancy who have a history of singleton spontaneous preterm birth. The effectiveness of Ostrolut (Hydroxyprogesterone Caproate) is based on improvement in the proportion of women who delivered < 37 weeks of gestation. There are no controlled trials demonstrating a direct clinical benefit, such as improvement in neonatal mortality and morbidity.
Limitation of use: While there are many risk factors for preterm birth, safety and efficacy of Ostrolut (Hydroxyprogesterone Caproate) has been demonstrated only in women with a prior spontaneous singleton preterm birth. It is not intended for use in women with multiple gestations or other risk factors for preterm birth.

In the clinical trial, 2.2% of subjects receiving Ostrolut (Hydroxyprogesterone Caproate) were reported as discontinuing therapy due to adverse reactions compared to 2.6% of control subjects. The most common adverse reactions that led to discontinuation in both groups were urticaria and injection site pain/swelling (1% each).
Pulmonary embolus in one subject and injection site cellulitis in another subject were reported as serious adverse reactions in Makena-treated subjects.
The following adverse reactions have been identified during postapproval use of Ostrolut (Hydroxyprogesterone Caproate). Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
In vitro drug-drug interaction studies were conducted with Ostrolut (Hydroxyprogesterone Caproate). No in vivo drug-drug interaction studies were conducted with Ostrolut (Hydroxyprogesterone Caproate).
Pregnancy: Controlled studies show no increase in congenital anomalies, including genital abnormalities in male or female infants, from exposure during pregnancy to Ostrolut. (8.1)
Pregnancy Category B: There are no adequate and well-controlled studies of Ostrolut (Hydroxyprogesterone Caproate) use in women during the first trimester of pregnancy. Data from a vehicle (placebo)-controlled clinical trial of 310 pregnant women who received Ostrolut (Hydroxyprogesterone Caproate) at weekly doses of 250 mg by intramuscular injection in their second and third trimesters1, as well as long-term (2-5 years) follow-up safety data on 194 of their infants 2, did not demonstrate any teratogenic risks to infants from in utero exposure to Ostrolut (Hydroxyprogesterone Caproate).
Reproduction studies have been performed in mice and rats at doses up to 95 and 5, respectively, times the human dose and have revealed no evidence of impaired fertility or harm to the fetus due to Ostrolut (Hydroxyprogesterone Caproate).
Ostrolut (Hydroxyprogesterone Caproate) administration produced embryolethality in rhesus monkeys but not in cynomolgus monkeys exposed to 1 and 10 times the human dose equivalent every 7 days between days 20 and 146 of gestation. There were no teratogenic effects in either species.
Ostrolut is not intended for use to stop active preterm labor. The effect of Ostrolut (Hydroxyprogesterone Caproate) in active labor is unknown.
Discontinue Ostrolut (Hydroxyprogesterone Caproate) at 37 weeks of gestation or upon delivery. Detectable amounts of progestins have been identified in the milk of mothers receiving progestin treatment. Many studies have found no adverse effects of progestins on breastfeeding performance, or on the health, growth, or development of the infant.
Ostrolut is not indicated for use in children. Safety and effectiveness in pediatric patients less than 16 years of age have not been established. A small number of women under age 18 years were studied; safety and efficacy are expected to be the same in women aged 16 years and above as for users 18 years and older.
Ostrolut (Hydroxyprogesterone Caproate) is not intended for use in postmenopausal women. Safety and effectiveness in postmenopausal women have not been established.
No studies have been conducted to examine the pharmacokinetics of Ostrolut in patients with renal impairment.
No studies have been conducted to examine the pharmacokinetics of Ostrolut (Hydroxyprogesterone Caproate) in patients with hepatic impairment. Ostrolut (Hydroxyprogesterone Caproate) is extensively metabolized and hepatic impairment may reduce the elimination of Ostrolut (Hydroxyprogesterone Caproate).
There have been no reports of adverse events associated with overdosage of Ostrolut (Hydroxyprogesterone Caproate) in clinical trials. In the case of overdosage, the patient should be treated symptomatically.
The active pharmaceutical ingredient in Ostrolut (Hydroxyprogesterone Caproate) is Ostrolut (Hydroxyprogesterone Caproate).
The chemical name for Ostrolut (Hydroxyprogesterone Caproate) is pregn-4-ene-3,20-dione, 17[(1-oxohexyl)oxy]. It has an empirical formula of C27H40O4 and a molecular weight of 428.60. Ostrolut (Hydroxyprogesterone Caproate) exists as white to practically white crystals or powder with a melting point of 120°-124°C.
The structural formula is:
Ostrolut (Hydroxyprogesterone Caproate) is a clear, yellow, sterile, non-pyrogenic solution for intramuscular injection. Each 1 mL single dose vial contains Ostrolut (Hydroxyprogesterone Caproate) USP, 250 mg/mL (25% w/v), in castor oil USP (30.6% v/v) and benzyl benzoate USP (46% v/v). Each 5 mL multidose vial contains Ostrolut (Hydroxyprogesterone Caproate) USP, 250 mg/mL (25% w/v), in castor oil USP (28.6% v/v) and benzyl benzoate USP (46% v/v) with the preservative benzyl alcohol NF (2% v/v).
Chemical Structure for Ostrolut (Hydroxyprogesterone Caproate)
Ostrolut is a synthetic progestin. The mechanism by which Ostrolut (Hydroxyprogesterone Caproate) reduces the risk of recurrent preterm birth is not known.
No specific pharmacodynamic studies were conducted with Ostrolut (Hydroxyprogesterone Caproate).
Absorption: Female patients with a singleton pregnancy received intramuscular doses of 250 mg Ostrolut for the reduction of preterm birth starting between 16 weeks 0 days and 20 weeks 6 days. All patients had blood drawn daily for 7 days to evaluate pharmacokinetics.
Blood was drawn daily for 7 days (1) starting 24 hours after the first dose between Weeks 16-20 (Group 1), (2) after a dose between Weeks 24-28 (Group 2), or (3) after a dose between Weeks 32-36 (Group 3) | |||
a Reported as median (range) | |||
b t = 7 days | |||
Group (N) | Cmax (ng/mL) | Tmax (days)a | AUC(1-t) b (ng·hr/mL) |
Group 1 (N=6) | 5.0 (1.5) | 5.5 (2.0-7.0) | 571.4 (195.2) |
Group 2 (N=8) | 12.5 (3.9) | 1.0 (0.9-1.9) | 1269.6 (285.0) |
Group 3 (N=11) | 12.3 (4.9) | 2.0 (1.0-3.0) | 1268.0 (511.6) |
For all three groups, peak concentration (Cmax) and area under the curve (AUC(1-7 days)) of the mono-hydroxylated metabolites were approximately 3-8-fold lower than the respective parameters for the parent drug, Ostrolut (Hydroxyprogesterone Caproate). While di-hydroxylated and tri-hydroxylated metabolites were also detected in human plasma to a lesser extent, no meaningful quantitative results could be derived due to the absence of reference standards for these multiple hydroxylated metabolites. The relative activity and significance of these metabolites are not known.
The elimination half-life of Ostrolut (Hydroxyprogesterone Caproate), as evaluated from 4 patients in the study who reached full-term in their pregnancies, was 16.4 (±3.6) days. The elimination half-life of the mono-hydroxylated metabolites was 19.7 (±6.2) days.
Distribution: Ostrolut (Hydroxyprogesterone Caproate) binds extensively to plasma proteins including albumin and corticosteroid binding globulins.
Metabolism: In vitro studies have shown that Ostrolut (Hydroxyprogesterone Caproate) can be metabolized by human hepatocytes, both by phase I and phase II reactions. Ostrolut (Hydroxyprogesterone Caproate) undergoes extensive reduction, hydroxylation and conjugation. The conjugated metabolites include sulfated, glucuronidated and acetylated products. In vitro data indicate that the metabolism of Ostrolut (Hydroxyprogesterone Caproate) is predominantly mediated by CYP3A4 and CYP3A5. The in vitro data indicate that the caproate group is retained during metabolism of Ostrolut (Hydroxyprogesterone Caproate).
Excretion: Both conjugated metabolites and free steroids are excreted in the urine and feces, with the conjugated metabolites being prominent. Following intramuscular administration to pregnant women at 10-12 weeks gestation, approximately 50% of a dose was recovered in the feces and approximately 30% recovered in the urine.
Renal Impairment: The effect of renal impairment on the pharmacokinetics of Ostrolut (Hydroxyprogesterone Caproate) has not been evaluated.
Hepatic Impairment: The effect of hepatic impairment on the pharmacokinetics of Ostrolut (Hydroxyprogesterone Caproate) has not been evaluated.
Cytochrome P450 (CYP) enzymes: An in vitro inhibition study using human liver microsomes and CYP isoform-selective substrates indicated that Ostrolut (Hydroxyprogesterone Caproate) increased the metabolic rate of CYP1A2, CYP2A6, and CYP2B6 by approximately 80%, 150%, and 80%, respectively. However, in another in vitro study using human hepatocytes under conditions where the prototypical inducers or inhibitors caused the anticipated increases or decreases in CYP enzyme activities, Ostrolut (Hydroxyprogesterone Caproate) did not induce or inhibit CYP1A2, CYP2A6, or CYP2B6 activity. Overall, the findings indicate that Ostrolut (Hydroxyprogesterone Caproate) has minimal potential for CYP1A2, CYP2A6, and CYP2B6 related drug-drug interactions at the clinically relevant concentrations.
In vitro data indicated that therapeutic concentration of Ostrolut (Hydroxyprogesterone Caproate) is not likely to inhibit the activity of CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A4.
Ostrolut (Hydroxyprogesterone Caproate) has not been adequately evaluated for carcinogenicity.
No reproductive or developmental toxicity or impaired fertility was observed in a multigenerational study in rats. Ostrolut (Hydroxyprogesterone Caproate) administered intramuscularly, at gestational exposures up to 5 times the recommended human dose, had no adverse effects on the parental (F0) dams, their developing offspring (F1), or the latter offspring's ability to produce a viable, normal second (F2) generation.
In a multicenter, randomized, double-blind, vehicle -controlled clinical trial, the safety and effectiveness of Ostrolut (Hydroxyprogesterone Caproate) for the reduction of the risk of spontaneous preterm birth was studied in women with a singleton pregnancy (age 16 to 43 years) who had a documented history of singleton spontaneous preterm birth (defined as delivery at less than 37 weeks of gestation following spontaneous preterm labor or premature rupture of membranes).1 At the time of randomization (between 16 weeks, 0 days and 20 weeks, 6 days of gestation), an ultrasound examination had confirmed gestational age and no known fetal anomaly. Women were excluded for prior progesterone treatment or heparin therapy during the current pregnancy, a history of thromboembolic disease, or maternal/obstetrical complications (such as current or planned cerclage, hypertension requiring medication, or a seizure disorder).
A total of 463 pregnant women were randomized to receive either Ostrolut (Hydroxyprogesterone Caproate) (N=310) or vehicle (N=153) at a dose of 250 mg administered weekly by intramuscular injection starting between 16 weeks, 0 days and 20 weeks, 6 days of gestation, and continuing until 37 weeks of gestation or delivery. Demographics of the Makena-treated women were similar to those in the control group, and included: 59.0% Black, 25.5% Caucasian, 13.9% Hispanic and 0.6% Asian. The mean body mass index was 26.9 kg/m2.
The proportions of women in each treatment arm who delivered at < 37 (the primary study endpoint), < 35, and < 32 weeks of gestation are displayed in Table 5.
1 Four Makena-treated subjects were lost to follow-up. They were counted as deliveries at their gestational ages at time of last contact (184, 220, 343 and364 weeks). 2 Adjusted for interim analysis. | |||
Delivery Outcome | Ostrolut (Hydroxyprogesterone Caproate)1 (N=310) % | Control (N=153) % | Treatment difference and 95% Confidence Interval2 |
<37 weeks | 37.1 | 54.9 | -17.8% [-28.0%, -7.4%] |
<35 weeks | 21.3 | 30.7 | -9.4% [-19.0%, -0.4%] |
<32 weeks | 11.9 | 19.6 | -7.7% [-16.1%, -0.3%] |
Compared to controls, treatment with Ostrolut (Hydroxyprogesterone Caproate) reduced the proportion of women who delivered preterm at < 37 weeks. The proportions of women delivering at < 35 and < 32 weeks also were lower among women treated with Ostrolut (Hydroxyprogesterone Caproate). The upper bounds of the confidence intervals for the treatment difference at < 35 and < 32 weeks were close to zero. Inclusion of zero in a confidence interval would indicate the treatment difference is not statistically significant. Compared to the other gestational ages evaluated, the number of preterm births at < 32 weeks was limited.
After adjusting for time in the study, 7.5% of Makena-treated subjects delivered prior to 25 weeks compared to 4.7% of control subjects; see Figure 1.

A composite neonatal morbidity/mortality index evaluated adverse outcomes in livebirths. It was based on the number of neonates who died or experienced respiratory distress syndrome, bronchopulmonary dysplasia, grade 3 or 4 intraventricular hemorrhage, proven sepsis, or necrotizing enterocolitis. Although the proportion of neonates who experienced 1 or more events was numerically lower in the Ostrolut (Hydroxyprogesterone Caproate) arm (11.9% vs. 17.2%), the number of adverse outcomes was limited and thedifference between arms was not statistically significant.

Infants born to women enrolled in this study, and who survived to be discharged from the nursery, were eligible for participation in a follow-up safety study. Of 348 eligible offspring, 79.9% enrolled: 194 children of Makena-treated women and 84 children of control subjects. The primary endpoint was the score on the Ages & Stages Questionnaire (ASQ), which evaluates communication, gross motor, fine motor, problem solving, and personal/social parameters. The proportion of children whose scores met the screening threshold for developmental delay in each developmental domain was similar for each treatment group.2
