骨密度的降低
尚无口服醋酸甲羟孕酮对骨密度(BMD)影响的研究。
然而有一项临床研究显示,成年育龄女性使用醋酸甲羟孕酮避孕,每3个月肌内注射150mg,5年后腰椎骨密度平均下降了5.4%,在停药后最初两年内至少有部分骨丢失得以恢复。另一项类似的临床试验也表明,青春期女性使用醋酸甲羟孕酮避孕,每3个月肌内注射150mg,也出现类似的骨密度降低,并且在给药的最初两年更为明显,停药后骨密度也至少有部分的恢复。由于醋酸甲羟孕酮引起的血清雌激素水平的下降可能导致绝经前女性骨密度降低,也可能增加以后患骨质疏松症的风险。
建议所有患者应摄取足量的钙和维生素D。
某些长期使用醋酸甲羟孕酮的患者可适当做骨密度评估。
对驾驶和操纵器械能力的影响
尚未进行系统评价醋酸甲羟孕酮对于驾驶和使用机器能力的影响。


 


【 孕妇及哺乳期妇女用药】


妊娠
本品禁用于妊娠女性。
一些报告提出在某些特定情况下,妊娠早期宫内暴露于孕激素类药物与胎儿生殖器异常有关。
如果患者在使用本品时妊娠,则应被告知本品对于胎儿的潜在危害。
哺乳
本品及其代谢产物可以分泌在乳汁中。虽尚无证据提示这将对被哺乳婴儿带来任何危害,仍建议在使用醋酸甲羟孕酮片治疗期间避免哺乳。


 


【 儿童用药】


不适用于儿童。 


【 老年用药】


没有证据显示老年患者与年轻患者相比在药物代谢方面存在差异。因此,相同的剂量、禁忌和注意事项适用于每个年龄组。 


【 药物相互作用】


氨鲁米特与醋酸甲羟孕酮同时使用时,可以显著地抑制醋酸甲羟孕酮的生物利用度。
与氨鲁米特合用情况下,应警告使用者其高剂量本品的疗效可能降低。
和所有的孕激素类药物相同,本品联合巴比妥、苯妥英、扑米酮、卡马西平、利福平和灰黄霉素等酶诱导剂治疗会增加肝脏的分解代谢。
孕激素能抑制环孢霉素代谢,从而增加血浆环孢霉素浓度,因此增加其毒性作用。
在某些患者中观察到应用孕激素时会出现糖耐量减低。其机制不明。因此,糖尿病患者在接受孕激素治疗期间应严密观察。在应用醋酸甲羟孕酮治疗时或治疗后,有必要调整降糖治疗方案。
在体外,醋酸甲羟孕酮主要是通过CYP3A4的羟基化作用进行代谢。评估CYP3A4诱导剂或抑制剂针对醋酸甲羟孕酮临床效果的专门药物相互作用研究尚未进行,因此CYP3A4诱导剂或抑制剂的临床效果未知。
与其他药物的相互作用及其他形式的相互作用
以下实验室检查结果可能受应用本品治疗所影响:
- 绒毛膜促性腺激素水平
- 血浆孕酮水平
- 尿孕二醇水平
- 血浆睾酮水平(男性)
- 血浆雌激素水平(女性)
- 血浆皮质醇水平
- 糖耐量试验
- 美替拉酮试验 


 


【 药物过量】


尚未观察到急性药物过量导致的症状。口服剂量最高至每天3g时耐受性良好。药物过量时应密切观察,采取对症和支持治疗。
接受药理学剂量水平的醋酸甲羟孕酮(400mg/天或更高)治疗癌症的患者偶尔会出现类似过量应用糖皮质激素的一些反应。对这些特殊病例也需注意观察,必要时考虑减少剂量。 


【 药理毒理】


药理作用
醋酸甲羟孕酮属于口服合成类固醇类药物,由孕酮衍生而成。除了6α位存在甲基和17位存在乙酰氧基外,本产品与天然孕酮有相同的结构。醋酸甲羟孕酮具有孕激素样作用及抗雌激素和抗促性腺激素作用。在一定剂量下,醋酸甲羟孕酮能同时在内分泌系统及细胞水平上发挥作用。
对某些特殊的激素依赖性肿瘤,药理学剂量水平的醋酸甲羟孕酮抗癌治疗有效性有赖于其对下丘脑-垂体-性腺轴、雌激素受体和组织水平的类固醇代谢的活性作用。在原代培养的恶性子宫内膜癌细胞中,醋酸甲羟孕酮能刺激雌、孕激素受体均阴性的细胞DNA合成,而对受体阳性细胞的DNA合成具有抑制作用。另一方面,高剂量的醋酸甲羟孕酮会导致严重的细胞膜结构变化,从而干扰一系列的细胞膜功能。
和孕酮类似,醋酸甲羟孕酮是产热物质。治疗某些癌症应用高剂量治疗(每天大于或等于500mg)时,会出现类肾上腺皮质激素效应。
毒理研究
有关研究试验动物应用醋酸甲羟孕酮后的毒理学数据显示:
LD50,口服-小鼠:大于10000mg/kg
LD50,腹膜内用药-小鼠:6985mg/kg
大鼠和小鼠中口服用药(334mg/kg/死亡)和狗口服用药(167mg/kg/死亡)30天,未观察到毒性效应。
在大鼠和狗应用3、10和30mg/kg/天,连续用药6个月的慢性毒性研究显示在以上剂量水平未发现任何毒性效应。
更高剂量时唯一观察到的效应是预期的激素效应。
在妊娠小猎犬中研究致畸作用,每天口服应用1、10和50mg/kg的醋酸甲羟孕酮,结果显示在应用高剂量治疗的妊娠小猎犬产下的雌小狗身上观察到阴蒂肥大。未在雄性小狗身上发现异常。
为了验证应用醋酸甲羟孕酮治疗的雌性动物后代的生殖能力进行了后续研究,未发现任何生育力下降。
研究在猴子、狗和大鼠肠外应用醋酸甲羟孕酮后的长期毒性,发现有以下效应:
1) 小猎犬应用剂量为3和75mg/kg,每90天一次,持续7年,发生乳房结节,但在对照组动物中也有发生。对照组中的结节为间断性发作,而用药组为大结节、多发、且持续存在,大剂量组中有2只动物发生恶性乳腺肿瘤。
2) 两只猴子应用的剂量为150mg/kg,每90天一次,持续10年,发生子宫未分化癌。而在对照组和应用3和30mg/kg,每90天一次,持续应用10年的治疗组中没有发生。间断性乳房结节在对照组和应用3和30mg/kg的治疗组中观察到,但在150mg/kg治疗组中未发现。10年后的尸体解剖发现仅3只30mg/kg治疗组的猴子有结节。组织病理学检查显示该结节为增生性结节。
3) 大鼠应用2年,未在子宫和乳腺组织观察到变化。
应用沙门氏微粒体试验(Ames试验)和微核试验研究醋酸甲羟孕酮的致突变作用,未发现其有致突变作用。
其他研究未发现在观察组动物的第一代或第二代有生育力变化。
尚不确定以上研究结果是否适用于人类。


 


【 药代动力学】


醋酸甲羟孕酮能从胃肠道快速吸收。健康志愿者在口服500mg醋酸甲羟孕酮后4.5小时,最高血浆值达78.7ng/ml至121ng/ml。餐时或餐后即刻服用吸收率最高。
醋酸甲羟孕酮的血浆蛋白结合率约为90~95%。口服给药后,醋酸甲羟孕酮的药代清除是以二次和三次方指数方式进行的。终末半衰期大约为30~60小时。
醋酸甲羟孕酮主要经胆道分泌,由粪便排泄。口服后大约44%的药物由尿液排泄。尿中的代谢产物有以下四种形式:
1、 非共价中性;
2、 葡萄糖醛酸苷共价中性;
3、 硫酸盐共价中性;
4、 酶抵抗酸性部分。

Provera

Generic Name: medroxyprogesterone acetate
Dosage Form: tablet

 

WARNING: CARDIOVASCULAR DISORDERS, BREAST CANCER AND PROBABLE DEMENTIA FOR ESTROGEN PLUS PROGESTIN THERAPY

Cardiovascular Disorders and Probable Dementia

Estrogen plus progestin therapy should not be used for the prevention of cardiovascular disease or dementia. (See CLINICAL STUDIES and WARNINGS, Cardiovascular Disorders and Probable Dementia.)

The Women's Health Initiative (WHI) estrogen plus progestin substudy reported an increased risk of deep vein thrombosis (DVT), pulmonary embolism (PE), stroke and myocardial infarction (MI) in postmenopausal women (50 to 79 years of age) during 5.6 years of treatment with daily oral conjugated estrogens (CE) [0.625 mg] combined with medroxyprogesterone acetate (MPA) [2.5 mg], relative to placebo. (See CLINICAL STUDIES and WARNINGS, Cardiovascular Disorders.)

The WHI Memory Study (WHIMS) estrogen plus progestin ancillary study reported an increased risk of developing probable dementia in postmenopausal women 65 years of age or older during 4 years of treatment with daily CE (0.625 mg) combined with MPA (2.5 mg), relative to placebo. It is unknown whether this finding applies to younger postmenopausal women. (See CLINICAL STUDIES and WARNINGS, Probable Dementia and PRECAUTIONS, Geriatric Use.)

Breast Cancer

The WHI estrogen plus progestin substudy demonstrated an increased risk of invasive breast cancer. (See CLINICAL STUDIES and WARNINGS, Malignant Neoplasm, Breast Cancer.)

In the absence of comparable data, these risks should be assumed to be similar for other doses of CE and MPA, and other combinations and dosage forms of estrogens and progestins.

Progestins with estrogens should be prescribed at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.

Provera - Clinical Pharmacology

Medroxyprogesterone acetate (MPA) administered orally or parenterally in the recommended doses to women with adequate endogenous estrogen, transforms proliferative into secretory endometrium. Androgenic and anabolic effects have been noted, but the drug is apparently devoid of significant estrogenic activity. While parenterally administered MPA inhibits gonadotropin production, which in turn prevents follicular maturation and ovulation, available data indicate that this does not occur when the usually recommended oral dosage is given as single daily doses.

Pharmacokinetics

The pharmacokinetics of MPA were determined in 20 postmenopausal women following a single-dose administration of eight Provera 2.5 mg tablets or a single administration of two Provera 10 mg tablets under fasting conditions. In another study, the steady-state pharmacokinetics of MPA were determined under fasting conditions in 30 postmenopausal women following daily administration of one Provera 10 mg tablet for 7 days. In both studies, MPA was quantified in serum using a validated gas chromatography-mass spectrometry (GC-MS) method. Estimates of the pharmacokinetic parameters of MPA after single and multiple doses of Provera tablets were highly variable and are summarized in Table 1.

A. Absorption

No specific investigation on the absolute bioavailability of MPA in humans has been conducted. MPA is rapidly absorbed from the gastrointestinal tract, and maximum MPA concentrations are obtained between 2 to 4 hours after oral administration.

Administration of Provera with food increases the bioavailability of MPA. A 10 mg dose of Provera, taken immediately before or after a meal, increased MPA Cmax (50 to 70%) and AUC (18 to 33%). The half-life of MPA was not changed with food.

B. Distribution

MPA is approximately 90% protein bound, primarily to albumin; no MPA binding occurs with sex hormone binding globulin.

C. Metabolism

Following oral dosing, MPA is extensively metabolized in the liver via hydroxylation, with subsequent conjugation and elimination in the urine.

D. Excretion

Most MPA metabolites are excreted in the urine as glucuronide conjugates with only minor amounts excreted as sulfates.

E. Specific Populations

Hepatic Insufficiency

MPA is almost exclusively eliminated via hepatic metabolism. In 14 patients with advanced liver disease, MPA disposition was significantly altered (reduced elimination). In patients with fatty liver, the mean percent dose excreted in the 24-hour urine as intact MPA after a 10 mg or 100 mg dose was 7.3% and 6.4%, respectively.

Renal Insufficiency

The effect of renal impairment on the pharmacokinetics of Provera has not been studied.

F. Drug Interactions

Medroxyprogesterone acetate (MPA) is metabolized in-vitro primarily by hydroxylation via the CYP3A4. Specific drug-drug interaction studies evaluating the clinical effects with CYP3A4 inducers or inhibitors on MPA have not been conducted. Inducers and/or inhibitors of CYP3A4 may affect the metabolism of MPA.

Clinical Studies
Effects on the Endometrium

In a 3-year, double-blind, placebo-controlled study of 356 nonhysterectomized, postmenopausal women between 45 and 64 years of age randomized to receive placebo (n=119), 0.625 mg conjugated estrogen only (n=119), or 0.625 mg conjugated estrogen plus cyclic Provera (n=118), results showed a reduced risk of endometrial hyperplasia in the treatment group receiving 10 mg Provera plus 0.625 mg conjugated estrogens compared to the group receiving 0.625 mg conjugated estrogens only. See Table 2.

Women's Health Initiative Studies

The WHI enrolled approximately 27,000 predominantly healthy postmenopausal women in two substudies to assess the risks and benefits of daily oral CE (0.625 mg)-alone or in combination with MPA (2.5 mg) compared to placebo in the prevention of certain chronic diseases. The primary endpoint was the incidence of coronary heart disease (CHD) (defined as nonfatal MI, silent MI and CHD death), with invasive breast cancer as the primary adverse outcome. A "global index" included the earliest occurrence of CHD, invasive breast cancer, stroke, PE, endometrial cancer (only in the CE plus MPA substudy), colorectal cancer, hip fracture, or death due to other cause. These substudies did not evaluate the effects of CE-alone or CE plus MPA on menopausal symptoms.

WHI Estrogen Plus Progestin Substudy

The WHI estrogen plus progestin substudy was stopped early. According to the predefined stopping rule, after an average follow-up of 5.6 years of treatment, the increased risk of invasive breast cancer and cardiovascular events exceeded the specified benefits included in the "global index." The absolute excess risk of events included in the "global index" was 19 per 10,000 women-years.

For those outcomes included in the WHI "global index" that reached statistical significance after 5.6 years of follow-up, the absolute excess risks per 10,000 women-years in the group treated with CE plus MPA were 7 more CHD events, 8 more strokes, 10 more PEs, and 8 more invasive breast cancers, while the absolute risk reduction per 10,000 women-years were 6 fewer colorectal cancers and 5 fewer hip fractures.

Results of the CE plus MPA substudy, which included 16,608 women (average 63 years of age, range 50 to 79; 83.9 percent White, 6.8 percent Black, 5.4 percent Hispanic, 3.9 percent Other) are presented in Table 4. These results reflect centrally adjudicated data after an average follow-up of 5.6 years.

The WHI estrogen plus progestin substudy stratified by age showed in women 50 to 59 years of age a nonsignificant trend toward reduced risk in overall mortality [hazard ration (HR) 0.69 (95 percent CI, 0.44–1.07)].

 

 

 

 

 

 

 

Women's Health Initiative Memory Study

The WHIMS estrogen plus progestin ancillary study of WHI enrolled 4,532 predominantly healthy postmenopausal women 65 years of age and older (47 percent were aged 65 to 69 years of age, 35 percent were 70 to 74 years of age, and 18 percent were 75 years of age and older) to evaluate the effects of daily CE (0.625 mg) plus MPA (2.5 mg) on the incidence of probable dementia (primary outcome) compared to placebo.

After an average follow-up of 4 years, the relative risk of probable dementia for CE plus MPA versus placebo was 2.05 (95 percent CI, 1.21–3.48). The absolute risk of probable dementia for CE plus MPA versus placebo was 45 versus 33 per 10,000 women-years. Probable dementia as defined in this study included Alzheimer's disease (AD), vascular dementia (VaD) and mixed type (having features of both AD and VaD). The most common classification of probable dementia in the treatment group and the placebo group was AD. Since the ancillary study was conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women. (See WARNINGS, Probable Dementia and PRECAUTIONS, Geriatric Use).

Indications and Usage for Provera

Provera tablets are indicated for the treatment of secondary amenorrhea and abnormal uterine bleeding due to hormonal imbalance in the absence of organic pathology, such as fibroids or uterine cancer. They are also indicated for use in the prevention of endometrial hyperplasia in nonhysterectomized postmenopausal women who are receiving daily oral conjugated estrogens 0.625 mg tablets.

Contraindications

Provera is contraindicated in women with any of the following conditions:

1.    Undiagnosed abnormal genital bleeding.

2.    Known, suspected, or history of breast cancer.

3.    Known or suspected estrogen- or progesterone-dependent neoplasia.

4.    ActiveDVT,PE, or a history of these conditions

5.    Active arterial thromboembolic disease (for example, stroke and MI), or a history of these conditions.

6.    Known anaphylactic reaction or angioedema to Provera.

7.    Known liver impairment or disease.

8.    Known or suspected pregnancy.

Warnings

See BOXED WARNINGS.

1. Cardiovascular Disorders

An increased risk of PE, DVT, stroke, and MI has been reported with estrogen plus progestin therapy. Should any of these events occur or be suspected, estrogen plus progestin therapy should be discontinued immediately.

Risk factors for arterial vascular disease (for example, hypertension, diabetes mellitus, tobacco use, hypercholesterolemia, and obesity) and/or venous thromboembolism (VTE) (for example, personal history or family history of VTE, obesity, and systemic lupus erythematosus) should be managed appropriately.

a. Stroke

In the WHI estrogen plus progestin substudy, a statistically significant increased risk of stroke was reported in women 50 to 79 years of age receiving CE (0.625 mg) plus MPA (2.5 mg) compared to women in the same age group receiving placebo (33 versus 25 per 10,000 women-years). (See CLINICAL STUDIES.) The increase in risk was demonstrated after the first year and persisted. Should a stroke occur or be suspected, estrogen plus progestin therapy should be discontinued immediately.

b. Coronary Heart Disease

In the WHI estrogen plus progestin substudy, there was a statistically non-significant increased risk of CHD events reported in women receiving daily CE (0.625 mg) plus MPA (2.5 mg) compared to women receiving placebo (41 versus 34 per 10,000 women-years). An increase in relative risk was demonstrated in year 1, and a trend toward decreasing relative risk was reported in years 2 through 5.

In postmenopausal women with documented heart disease (n = 2,763, average 66.7 years of age), in a controlled clinical trial of secondary prevention of cardiovascular disease (Heart and Estrogen/Progestin Replacement Study [HERS]), treatment with daily CE (0.625 mg) plus MPA (2.5mg) demonstrated no cardiovascular benefit. During an average follow-up of 4.1 years, treatment with CE plus MPA did not reduce the overall rate of CHD events in postmenopausal women with established coronary heart disease. There were more CHD events in the CE plus MPA-treated group than in the placebo group in year 1, but not during the subsequent years. Two thousand three hundred and twenty-one (2,321) women from the original HERS trial agreed to participate in an open label extension of HERS, HERS II. Average follow-up in HERS II was an additional 2.7 years, for a total of 6.8 years overall. Rates of CHD events were comparable among women in the CE plus MPA group and the placebo group in HERS, HERS II, and overall.

c. Venous Thromboembolism

 

 

 

In the WHI estrogen plus progestin substudy, a statistically significant 2-fold greater rate of VTE (DVT and PE) was reported in women receiving daily CE (0.625 mg) plus MPA (2.5 mg) compared to women receiving placebo (35 versus 17 per 10,000 women-years). Statistically significant increases in risk for both DVT (26 versus 13 per 10,000 women-years) and PE (18 versus 8 per 10,000 women-years) were also demonstrated. The increase in VTE risk was demonstrated during the first year and persisted. (See CLINICAL STUDIES.) Should a VTE occur or be suspected, estrogen plus progestin therapy should be discontinued immediately.

If feasible, estrogens plus progestins should be discontinued at least 4 to 6 weeks before surgery of the type associated with an increased risk of thromboembolism, or during periods of prolonged immobilization.

2. Malignant Neoplasms

a. Breast Cancer

The most important randomized clinical trial providing information about breast cancer in estrogen plus progestin users is the WHI substudy of daily CE (0.625 mg) plus MPA (2.5 mg). After a mean follow-up of 5.6 years, the estrogen plus progestin substudy reported an increased risk of invasive breast cancer in women who took daily CE plus MPA.

In this substudy, prior use of estrogen-alone or estrogen plus progestin therapy was reported by 26 percent of the women. The relative risk of invasive breast cancer was 1.24, and the absolute risk was 41 versus 33 cases per 10,000 women-years, for CE plus MPA compared with placebo. Among women who reported prior use of hormone therapy, the relative risk of invasive breast cancer was 1.86, and the absolute risk was 46 versus 25 cases per 10,000 women-years, for CE plus MPA compared with placebo. Among women who reported no prior use of hormone therapy, the relative risk of invasive breast cancer was 1.09, and the absolute risk was 40 versus 36 cases per 10,000 women-years, for CE plus MPA compared with placebo. In the same substudy, invasive breast cancers were larger, were more likely to be node positive, and were diagnosed at a more advanced stage in the CE (0.625 mg) plus MPA (2.5 mg) group compared with the placebo group. Metastatic disease was rare with no apparent difference between the two groups. Other prognostic factors such as histologic subtype, grade, and hormone receptor status did not differ between the groups. (See CLINICAL STUDIES.)

Consistent with the WHI clinical trial, observational studies have also reported an increased risk of breast cancer for estrogen plus progestin therapy, and a smaller risk for estrogen-alone therapy, after several years of use. The risk increased with duration of use, and appeared to return to baseline over about 5 years after stopping treatment (only the observational studies have substantial data on risk after stopping). Observational studies also suggest that the risk of breast cancer was greater, and became apparent earlier, with estrogen plus progestin therapy as compared to estrogen-alone therapy. However, these studies have not found significant variation in the risk of breast cancer among different estrogen plus progestin combinations, or routes of administration.

The use of estrogen plus progestin has been reported to result in an increase in abnormal mammograms requiring further evaluation. All women should receive yearly breast examinations by a healthcare provider and perform monthly breast self-examinations. In addition, mammography examinations should be scheduled based on patient age, risk factors, and prior mammogram results.

b. Endometrial Cancer

An increased risk of endometrial cancer has been reported with the use of unopposed estrogen therapy in women with a uterus. The reported endometrial cancer risk among unopposed estrogen users is about 2 to 12 times greater than in non-users, and appears dependent on duration of treatment and on estrogen dose. Most studies show no significant increased risk associated with the use of estrogens for less than 1 year. The greatest risk appears associated with prolonged use, with increased risks of 15- to 24-fold for 5 to 10 years or more. This risk has been shown to persist for at least 8 to 15 years after estrogen therapy is discontinued.

Clinical surveillance of all women using estrogen plus progestin therapy is important. Adequate diagnostic measures, including endometrial sampling when indicated, should be undertaken to rule out malignancy in all cases of undiagnosed persistent or recurring abnormal genital bleeding. There is no evidence that the use of natural estrogens results in a different endometrial risk profile than synthetic estrogens of equivalent estrogen dose. Adding a progestin to estrogen therapy has been shown to reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer.

c. Ovarian Cancer

The WHI estrogen plus progestin substudy reported a statistically non-significant increased risk of ovarian cancer. After an average follow-up of 5.6 years, the relative risk for ovarian cancer for CE plus MPA versus placebo was 1.58 (95 percent CI, 0.77–3.24). The absolute risk for CE plus MPA was 4 versus 3 cases per 10,000 women-years. In some epidemiologic studies, the use of estrogen plus progestin and estrogen-only products, in particular for 5 or more years, has been associated with increased risk of ovarian cancer. However, the duration of exposure associated with increased risk is not consistent across all epidemiologic studies and some report no association.

3. Probable Dementia

In the WHIMS estrogen plus progestin ancillary study of WHI, a population of 4,532 postmenopausal women aged 65 to 79 years was randomized to daily CE (0.625 mg) plus MPA (2.5 mg) or placebo.

After an average follow-up of 4 years, 40 women in the CE plus MPA group and 21 women in the placebo group were diagnosed with probable dementia. The relative risk of probable dementia for CE plus MPA versus placebo was 2.05 (95 percent CI, 1.21–3.48). The absolute risk of probable dementia for CE plus MPA versus placebo was 45 versus 22 cases per 10,000 women-years. It is unknown whether these findings apply to younger postmenopausal women. (See CLINICAL STUDIES and PRECAUTIONS, Geriatric Use.)

 

 

4. Visual Abnormalities

Discontinue estrogen plus progestin therapy pending examination if there is sudden partial or complete loss of vision, or a sudden onset of proptosis, diplopia or migraine. If examination reveals papilledema or retinal vascular lesions, estrogen plus progestin therapy should be permanently discontinued.

Precautions
A. General

1. Addition of a progestin when a woman has not had a hysterectomy

Studies of the addition of a progestin for 10 or more days of a cycle of estrogen administration, or daily with estrogen in a continuous regimen, have reported a lowered incidence of endometrial hyperplasia than would be induced by estrogen treatment alone. Endometrial hyperplasia may be a precursor to endometrial cancer.

There are, however, possible risks that may be associated with the use of progestins with estrogens compared to estrogen-alone regimens. These include an increased risk of breast cancer.

2. Unexpected abnormal vaginal bleeding

In cases of unexpected abnormal vaginal bleeding, adequate diagnostic measures are indicated.

3. Elevated blood pressure

Blood pressure should be monitored at regular intervals with estrogen plus progestin therapy.

4. Hypertriglyceridemia

In women with pre-existing hypertriglyceridemia, estrogen plus progestin therapy may be associated with elevations of plasma triglycerides leading to pancreatitis. Consider discontinuation of treatment if pancreatitis occurs.

5. Hepatic Impairment and/or past history of cholestatic jaundice

Estrogens plus progestins may be poorly metabolized in women with impaired liver function. For women with a history of cholestatic jaundice associated with past estrogen use or with pregnancy, caution should be exercised, and in the case of recurrence, medication should be discontinued.

6. Fluid Retention

Progestins may cause some degree of fluid retention. Women who have conditions which might be influenced by this factor, such as cardiac or renal impairment, warrant careful observation when estrogen plus progestin are prescribed.

7. Hypocalcemia

Estrogen plus progestin therapy should be used with caution in women with hypoparathyroidism as estrogen-induced hypocalcemia may occur.

8. Exacerbation of other conditions

Estrogen plus progestin therapy may cause an exacerbation of asthma, diabetes mellitus, epilepsy, migraine, porphyria, systemic lupus erythematosus, and hepatic hemangiomas and should be used with caution in women with these conditions.

B. Patient Information

Physicians are advised to discuss the Patient Information leaflet with women for whom they prescribe Provera.

There may be an increased risk of minor birth defects in children whose mothers are exposed to progestins during the first trimester of pregnancy. The possible risk to the male baby is hypospadias, a condition in which the opening of the penis is on the underside rather than the tip of the penis. This condition occurs naturally in approximately 5 to 8 per 1000 male births. The risk may be increased with exposure to Provera. Enlargement of the clitoris and fusion of the labia may occur in female babies. However, a clear association between hypospadias, clitoral enlargement and labial fusion with use of Provera has not been established.

Inform the patient of the importance of reporting exposure to Provera in early pregnancy.

C. Drug-Laboratory Test Interactions

The following laboratory results may be altered by the use of estrogen plus progestin therapy:

1.    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 anti-factor Xa and antithrombin III, decreased antithrombin III activity; increased levels of fibrinogen and fibrinogen activity; increased plasminogen antigen and activity.

2.    Increased thyroid-binding globulin (TBG) 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. Women on thyroid replacement therapy may require higher doses of thyroid hormone.

3.    Other binding proteins may be elevated in serum, for example, corticosteroid binding globulin (CBG), sex hormone binding globulin (SHBG) leading to increased circulating corticosteroid and sex steroids, respectively. Free hormone concentrations, such as testosterone and estradiol, may be decreased. Other plasma proteins may be increased (angiotensinogen/renin substrate, alpha-1-antitrypsin, ceruloplasmin).

4.    Increased plasma high-density lipoprotein (HDL) and HDL2 cholesterol subfraction concentrations, reduced low-density lipoprotein (LDL) cholesterol concentration, increased triglycerides levels.

5.    Impaired glucose tolerance

 

 

 

 

D. Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity

Long-term intramuscular administration of medroxyprogesterone acetate has been shown to produce mammary tumors in beagle dogs. There was no evidence of a carcinogenic effect associated with the oral administration of medroxyprogesterone acetate to rats and mice.

Long-term continuous administration of estrogen plus progestin therapy has shown an increased risk of breast cancer and ovarian cancer. (See WARNINGS and PRECAUTIONS.)

Genotoxicity

Medroxyprogesterone acetate was not mutagenic in a battery of in vitro or in vivo genetic toxicity assays.

Fertility

Medroxyprogesterone acetate at high doses is an antifertility drug and high doses would be expected to impair fertility until the cessation of treatment.

E. Pregnancy

Provera should not be used during pregnancy. (See CONTRAINDICATIONS.)

There may be increased risks for hypospadias, clitoral enlargement and labial fusion in children whose mothers are exposed to Provera during the first trimester of pregnancy. However, a clear association between these conditions with use of Provera has not been established.

F. Nursing Mothers

Provera should not be used during lactation. Detectable amounts of progestin have been identified in the breast milk of nursing mothers receiving progestins.

G. Pediatric Use

Provera tablets are not indicated in children. Clinical studies have not been conducted in the pediatric population.

H. Geriatric Use

There have not been sufficient numbers of geriatric women involved in clinical studies utilizing Provera alone to determine whether those over 65 years of age differ from younger subjects in their response to Provera alone.

The Women's Health Initiative Studies

In the WHI estrogen plus progestin substudy (daily CE [0.625 mg] plus MPA [2.5 mg] versus placebo), there was a higher relative risk of nonfatal stroke and invasive breast cancer in women greater than 65 years of age. (See CLINICAL STUDIES.)

The Women's Health Initiative Memory Study

In the WHIMS ancillary studies of postmenopausal women 65 to 79 years of age, there was an increased risk of developing probable dementia in women receiving estrogen-alone or estrogen plus progestin when compared to placebo. (See WARNINGS, Probable Dementia.)

Since both ancillary studies were conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women. (See WARNINGS, Probable Dementia.)

Adverse Reactions

See BOXED WARNINGS, WARNINGS, and PRECAUTIONS.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The following adverse reactions have been reported in women taking Provera tablets, without concomitant estrogens treatment:

1. Genitourinary system

Abnormal uterine bleeding (irregular, increase, decrease), change in menstrual flow, breakthrough bleeding, spotting, amenorrhea, changes in cervical erosion and cervical secretions.

2. Breasts

Overdosage

Overdosage of estrogen plus progestin therapy may cause nausea and vomiting, breast tenderness, dizziness, abdominal pain, drowsiness/fatigue and withdrawal bleeding may occur in women. Treatment of overdose consists of discontinuation of CE plus MPA together with institution of appropriate symptomatic care.

Provera Dosage and Administration
Secondary Amenorrhea

Provera tablets may be given in dosages of 5 or 10 mg daily for 5 to 10 days. A dose for inducing an optimum secretory transformation of an endometrium that has been adequately primed with either endogenous or exogenous estrogen is 10 mg of Provera daily for 10 days. In cases of secondary amenorrhea, therapy may be started at any time. Progestin withdrawal bleeding usually occurs within three to seven days after discontinuing Provera therapy.

Abnormal Uterine Bleeding Due to Hormonal Imbalance in the Absence of Organic Pathology

Beginning on the calculated 16th or 21st day of the menstrual cycle, 5 or 10 mg of Provera may be given daily for 5 to 10 days. To produce an optimum secretory transformation of an endometrium that has been adequately primed with either endogenous or exogenous estrogen, 10 mg of Provera daily for 10 days beginning on the 16th day of the cycle is suggested. Progestin withdrawal bleeding usually occurs within three to seven days after discontinuing therapy with Provera. Patients with a past history of recurrent episodes of abnormal uterine bleeding may benefit from planned menstrual cycling with Provera

 

 

 

Reduction of Endometrial Hyperplasia in Postmenopausal Women Receiving Daily 0.625 mg Conjugated Estrogens

When estrogen is prescribed for a postmenopausal woman with a uterus, a progestin should also be initiated to reduce the risk of endometrial cancer. A woman without a uterus does not need progestin. Use of estrogen, alone or in combination with a progestin, should be with the lowest effective dose and for the shortest duration consistent with treatment goals and risks for the individual woman. Patients should be re-evaluated periodically as clinically appropriate (for example, 3 to 6 month intervals) to determine if treatment is still necessary (see WARNINGS). For women who have a uterus, adequate diagnostic measures, such as endometrial sampling, when indicated, should be undertaken to rule out malignancy in cases of undiagnosed persistent or recurring abnormal vaginal bleeding.

Provera tablets may be given in dosages of 5 or 10 mg daily for 12 to 14 consecutive days per month, in postmenopausal women receiving daily 0.625 mg conjugated estrogens, either beginning on the 1st day of the cycle or the 16th day of the cycle.

Patients should be started at the lowest dose.

The lowest effective dose of Provera has not been determined.

PATIENT INFORMATION

Provera
(
pro-VE-rah)
(medroxyprogesterone acetate tablets, USP)

Read this Patient Information before you start taking Provera and read what you get each time you refill your Provera prescription. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment.

What is the most important information I should know about Provera (a progestin hormone)?

·                                 Do not use estrogens with progestins to prevent heart disease, heart attacks, strokes, or dementia (decline in brain function).

·                                 Using estrogens with progestins may increase your chance of getting heart attacks, strokes, breast cancer, and blood clots.

·                                 Using estrogens with progestins may increase your chance of getting dementia, based on a study of women age 65 years or older.

·                                 You and your healthcare provider should talk regularly about whether you still need treatment with Provera.

What is Provera?

Provera is a medicine that contains medroxyprogesterone acetate, a progestin hormone.

What is Provera used for?

Provera is used to:

Treat menstrual periods that have stopped or to treat abnormal uterine bleeding. Women with a uterus who are not pregnant, who stop having regular menstrual periods or who begin to have irregular menstrual periods may have a drop in their progesterone level. Talk with your healthcare provider about whether Provera is right for you.Reduce your chances of getting cancer of the uterus (womb). In postmenopausal women with a uterus who use estrogens, taking progestin in combination with estrogen will reduce your chance of getting cancer of the uterus (womb)

 

 

 

 

 

 

 

 

Who should not take Provera?

Do not start taking Provera if you:

· have unusual vaginal bleeding

· currently have or have had certain cancers
Estrogen plus progestin may increase your chance of getting certain types of cancers, including cancer of the breast. If you have or have had cancer, talk with your healthcare provider about whether you should use Provera.

· had a stroke or heart attack

· currently have or have had blood clots

· currently have or have had liver problems

· are allergic to Provera or any of its ingredients
See the list of ingredients in Provera at the end of this leaflet.

· think you may be pregnant
Provera is not for pregnant women. If you think you may be pregnant, you should have a pregnancy test and know the results. Do not use Provera if the test is positive and talk to your healthcare provider. There may be an increased risk of minor birth defects in children whose mothers take Provera during the first 4 months of pregnancy.
Provera should not be used as a test for pregnancy.

What should I tell my healthcare provider before taking Provera? Before you take Provera, tell your healthcare provider if you:

· have any other medical problems
Your healthcare provider may need to check you more carefully if you have certain conditions such as asthma (wheezing), epilepsy (seizures), diabetes, migraine, endometriosis (severe pelvic pain), lupus, or problems with your heart, liver, thyroid, kidneys, or have high calcium in your blood.

· are going to have surgery or will be on bed rest
Your healthcare provider will let you know if you need to stop taking Provera.

· are breast feeding
The hormone in Provera can pass into your breast milk.

Tell your healthcare provider about all the medicines you take including prescription and nonprescription medicines, vitamins, and herbal supplements. Some medicines may affect how Provera works. Provera may also affect how other medicines work.

How should I take Provera?

Start at the lowest dose and talk to your healthcare provider about how well that dose is working for you. The lowest effective dose of Provera has not been determined. You and your healthcare provider should talk regularly (every 3 to 6 months) about the dose you are taking and whether you still need treatment with Provera.

1.    Absence of menstrual period: Provera may be given in doses ranging from 5 to 10 mg daily for 5 to 10 days.

2.    Abnormal Uterine Bleeding: Provera may be given in doses ranging from 5 to 10 mg daily for 5 to 10 days.

3.    Overgrowth of the lining of the uterus: When used in combination with oral conjugated estrogens in postmenopausal women with a uterus, Provera may be given in doses ranging from 5 or 10 mg daily for 12 to 14 straight days per month.
