Prolin-N Acetate structural formula

CLINICAL PHARMACOLOGY

Prolin-N acetate induces secretory changes in an estrogen-primed endometrium. On a weight basis, it is twice as potent as Prolin-N.

Pharmacokinetics

Absorption

Prolin-N acetate is completely and rapidly deacetylated to Prolin-N after oral administration, and the disposition of Prolin-N acetate is indistinguishable from that of orally administered Prolin-N. Prolin-N acetate is rapidly absorbed from Prolin-N tablets, with maximum plasma concentration of Prolin-N generally occurring at about 2 hours post-dose. The pharmacokinetic parameters of Prolin-N following single oral administration of Prolin-N in 29 healthy female volunteers are summarized in Table 1.

Effect of Food

The effect of food administration on the pharmacokinetics of Prolin-N has not been studied.

Distribution

Prolin-N is 36% bound to sex hormone-binding globulin and 61% bound to albumin. Volume of distribution of Prolin-N is about 4 L/kg.

Metabolism

Prolin-N undergoes extensive biotransformation, primarily via reduction, followed by sulfate and glucuronide conjugation. The majority of metabolites in the circulation are sulfates, with glucuronides accounting for most of the urinary metabolites.

Excretion

Plasma clearance value for Prolin-N is approximately 0.4 L/hr/kg. Prolin-N is excreted in both urine and feces, primarily as metabolites. The mean terminal elimination half-life of Prolin-N following a single dose administration of Prolin-N is approximately 9 hours.

Special Populations

Geriatrics

The effect of age on the pharmacokinetics of Prolin-N after Prolin-N administration has not been evaluated.

Race

The effect of race on the disposition of Prolin-N after Prolin-N administration has not been evaluated.

Renal Insufficiency

The effect of renal disease on the disposition of Prolin-N after Prolin-N administration has not been evaluated. In premenopausal women with chronic renal failure undergoing peritoneal dialysis who received multiple doses of an oral contraceptive containing ethinyl estradiol and Prolin-N, plasma Prolin-N concentration was unchanged compared to concentrations in premenopausal women with normal renal function.

Hepatic Insufficiency

The effect of hepatic disease on the disposition of Prolin-N after Prolin-N administration has not been evaluated. However, Prolin-N is contraindicated in markedly impaired liver function or liver disease.

Drug Interactions

No pharmacokinetic drug interaction studies investigating any drug-drug interactions with Prolin-N have been conducted.

INDICATIONS AND USAGE

Prolin-N (norethindrone acetate tablets USP) is indicated for the treatment of secondary amenorrhea, endometriosis, and abnormal uterine bleeding due to hormonal imbalance in the absence of organic pathology, such as submucous fibroids or uterine cancer. Prolin-N (norethindrone acetate tablets USP) is not intended, recommended or approved to be used with concomitant estrogen therapy in postmenopausal women for endometrial protection.

CONTRAINDICATIONS

Known or suspected pregnancy. There is no indication for Prolin-N in pregnancy. (See PRECAUTIONS .)
Undiagnosed vaginal bleeding
Known, suspected or history of cancer of the breast
Active deep vein thrombosis, pulmonary embolism or history of these conditions
Active or recent (e.g., within the past year) arterial thromboembolic disease (e.g., stroke, myocardial infarction)
Impaired liver function or liver disease
As a diagnostic test for pregnancy
Hypersensitivity to any of the drug components

WARNINGS

Cardiovascular Disorders
Patients with risk factors for arterial vascular disease (e.g., hypertension, diabetes mellitus, tobacco use, hypercholesterolemia, and obesity) and/or venous thromboembolism (e.g., personal history or family history of VTE, obesity, and systemic lupus erythematosus) should be managed appropriately.
Visual Abnormalities
Discontinue medication pending examination if there is a sudden partial or complete loss of vision or if there is sudden onset of proptosis, diplopia, or migraine. If examination reveals papilledema or retinal vascular lesions, medication should be discontinued.

PRECAUTIONS

General

Because this drug may cause some degree of fluid retention, conditions which might be influenced by this factor, such as epilepsy, migraine, cardiac or renal dysfunctions, require careful observation.
In cases of breakthrough bleeding, and in all cases of irregular bleeding per vagina, nonfunctional causes should be borne in mind. In cases of undiagnosed vaginal bleeding, adequate diagnostic measures are indicated.
Patients who have a history of clinical depression should be carefully observed and the drug discontinued if the depression recurs to a serious degree.
Data suggest that progestin therapy may have adverse effects on lipid and carbohydrate metabolism. The choice of progestin, its dose, and its regimen may be important in minimizing these adverse effects, but these issues will require further study before they are clarified. Women with hyperlipidemias and/or diabetes should be monitored closely during progestin therapy.
The pathologist should be advised of progestin therapy when relevant specimens are submitted.

Information for the Patient

Healthcare providers are advised to discuss the PATIENT INFORMATION leaflet with patients for whom they prescribe Prolin-N.

Drug/Laboratory Tests Interactions

The following laboratory test results may be altered by the use of estrogen/progestin combination drugs:

Accelerated prothrombin time, partial thromboplastin time, and platelet aggregation time; increased platelet count; increased factors II, VII antigen, VIII antigen, VIII coagulant activity, IX, X, XII, VII-X complex, II-VII-X complex, and beta-thromboglobulin; decreased levels of antifactor X_a and antithrombin III, decreased antithrombin III activity; increased levels of fibrinogen and fibrinogen activity; increased plasminogen antigen and activity.
Increased thyroid-binding globulin levels leading to increased circulating total thyroid hormone levels as measured by protein-bound iodine (PBI), T₄ levels (by column or by radioimmunoassay) or T₃ levels by radioimmunoassay. T₃ resin uptake is decreased, reflecting the elevated TBG. Free T₄ and free T₃ concentrations are unaltered. Patients on thyroid replacement therapy may require higher doses of thyroid hormone.
Other binding proteins may be elevated in serum (i.e., corticosteroid binding globulin (CBG), sex hormone binding globulin (SHBG)) leading to increased circulating corticosteroid and sex steroids, respectively. Free or biologically active hormone concentrations are unchanged. Other plasma proteins may be increased (angiotensinogen/renin substrate, alpha-1-antitrypsin, ceruloplasmin).
Increased plasma HDL and HDL₂ cholesterol subfraction concentrations, reduced LDL cholesterol concentration, increased triglycerides levels.
Impaired glucose metabolism.
Reduced response to metyrapone test.

Carcinogenesis, Mutagenesis, and Impairment of Fertility

Some beagle dogs treated with medroxyprogesterone acetate developed mammary nodules. Although nodules occasionally appeared in control animals, they were intermittent in nature, whereas nodules in treated animals were larger and more numerous, and persisted. There is no general agreement as to whether the nodules are benign or malignant. Their significance with respect to humans has not been established.

Pregnancy

Category X

Prolin-N acetate is contraindicated during pregnancy as it may cause fetal harm when administered to pregnant women. Several reports suggest an association between intrauterine exposure to progestational drugs in the first trimester of pregnancy and congenital abnormalities in male and female fetuses. Some progestational drugs induce mild virilization of the external genitalia of female fetuses.

Nursing Mothers

Detectable amounts of progestins have been identified in the milk of mothers receiving them. Caution should be exercised when progestins are administered to a nursing woman.

Pediatric Use

Prolin-N tablets are not indicated in children.

ADVERSE REACTIONS

See WARNINGS and PRECAUTIONS .

The following adverse reactions have been observed in women taking progestins:

Breakthrough bleeding
Spotting
Change in menstrual flow
Amenorrhea
Edema
Changes in weight (decreases, increases)
Changes in the cervical squamo-columnar junction and cervical secretions
Cholestatic jaundice
Rash (allergic) with and without pruritus
Melasma or chloasma
Clinical depression
Acne
Breast enlargement/tenderness
Headache/migraine
Urticaria
Abnormalities of liver tests (i.e., AST, ALT, Bilirubin)
Decreased HDL cholesterol and increased LDL/HDL ratio
Mood swings
Nausea
Insomnia
Anaphylactic/anaphylactoid reactions
Thrombotic and thromboembolic events (e.g., deep vein thrombosis, pulmonary embolism, retinal vascular thrombosis, cerebral thrombosis and embolism)
Optic neuritis (which may lead to partial or complete loss of vision)

DOSAGE AND ADMINISTRATION

Therapy with Prolin-N must be adapted to the specific indications and therapeutic response of the individual patient.

Secondary amenorrhea, abnormal uterine bleeding due to hormonal imbalance in the absence of organic pathology

2.5 to 10 mg Prolin-N may be given daily for 5 to 10 days to produce secretory transformation of an endometrium that has been adequately primed with either endogenous or exogenous estrogen.

Progestin withdrawal bleeding usually occurs within three to seven days after discontinuing Prolin-N therapy. Patients with a past history of recurrent episodes of abnormal uterine bleeding may benefit from planned menstrual cycling with Prolin-N.

Endometriosis

Initial daily dosage of 5 mg Prolin-N for two weeks. Dosage should be increased by 2.5 mg per day every two weeks until 15 mg per day of Prolin-N is reached. Therapy may be held at this level for six to nine months or until annoying breakthrough bleeding demands temporary termination.

Read this PATIENT INFORMATION before you start taking Prolin-N and read what you get each time you refill Prolin-N. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition.

What is the most important information I should know about Prolin-N (A Progestin Hormone)?

Do not use Prolin-N if you are pregnant, breastfeeding or are trying to conceive.
Do not use Prolin-N if you have had a previous blood clot, stroke, or heart attack.
Do not use Prolin-N if you are postmenopausal.

What is Prolin-N?

Prolin-N is similar to the progesterone hormones naturally produced by the body. Your healthcare provider may provide Prolin-N as individual tablets.

What are Prolin-N used for?

Prolin-N are used for the treatment of secondary amenorrhea (absence of menstrual periods in women who have previously had a menstrual period who are not pregnant), the treatment of endometriosis, and the treatment of irregular menstrual periods due to hormone imbalance.

Who should not take Prolin-N?

You should not take Prolin-N if you are postmenopausal, pregnant or breastfeeding.

You should not take Prolin-N if you have the following conditions:

Known or suspected pregnancy. Prolin-N are not indicated during pregnancy as it may cause fetal harm when administered to pregnant women. There is an increased risk of minor birth defects in children whose mothers take Prolin-N during the first 4 months of pregnancy (mild masculinization of the external genitalia of the female fetus, as well as hypospadias in the male fetus). If you take Prolin-N and later find out you were pregnant, talk with your healthcare provider right away.
History of blood clots in the legs, lungs, eyes, brain, or elsewhere, or a past history of these conditions
Liver impairment or disease

Undiagnosed vaginal bleeding
Hypersensitivity to Prolin-N. See the end of this leaflet for a list of all of the ingredients in Prolin-N.

What are the risks associated with Prolin-N?

Risk to the Fetus

Prolin-N should not be used if you are pregnant. Prolin-N are contraindicated during pregnancy as it may cause fetal harm when administered to pregnant women. There is an increased risk of minor birth defects in children whose mothers take this drug during the first 4 months of pregnancy. Several reports suggest an association between mothers who take these drugs in the first trimester of pregnancy and congenital abnormalities in male and female babies. Although it is not clear that these events were drug related, you should check with your healthcare provider about the risks to your unborn child of any medication taken during pregnancy.

You should avoid using Prolin-N during pregnancy. If you take Prolin-N and later find you were pregnant when you took it, be sure to discuss this with your healthcare provider as soon as possible.

Abnormal Blood Clotting

Use of progestational drugs, such as Prolin-N, has been associated with changes in the blood-clotting system. These changes allow the blood to clot more easily, possibly allowing clots to form in the bloodstream. If blood clots do form in your bloodstream, they can cut off the blood supply to vital organs, causing serious problems. These problems may include a stroke (by cutting off blood to part of the brain), a heart attack (by cutting off blood to part of the heart), a pulmonary embolus (by cutting off blood to part of the lungs), visual loss or blindness (by cutting off blood vessels in the eye), or other problems. Any of these conditions may cause death or serious long-term disability. Call your healthcare provider right away if you suspect you have any of these conditions. He or she may advise you to stop using the drug.

Eye Abnormalities

Discontinue Prolin-N tablets and call your healthcare provider right away if you experience sudden partial or complete loss of vision, blurred vision, or sudden onset of bulging eyes, double vision, or migraine.

These are some of the warning signs of serious side effects with progestin therapy

Breast lumps
Dizziness and faintness
Changes in speech
Severe headaches
Chest pain
Shortness of breath
Pains in your legs
Changes in vision

Call your healthcare provider right away if you get any of these warning signs, or any other unusual symptom that concerns you.

Common side effects include

Headache
Breast pain
Irregular vaginal bleeding or spotting
Stomach/abdominal cramps/bloating
Nausea and vomiting
Hair loss

Other side effects include

High blood pressure
Liver problems
High blood sugar
Fluid retention
Enlargements of benign tumors of the uterus (“fibroids”)
