部份中文EllaOne处方资料(仅供参考)
【中文名称】醋酸乌利司他
【英文商标】EllaOne
【英文名称】ulipristal acetate
【剂型及规格】片剂,30mg
【作用机制】醋酸乌利司他(ulipristal acetate)是一种孕酮激动剂/拮抗剂,其作用机制是抑制或延迟排卵;然而,子宫内膜的改变也可能是产生疗效的原因之一。
【药效学】
醋酸乌利司他属于选择性孕酮受体调节剂,对孕酮受体有拮抗和部分激动作用。它与人体内孕酮受体结合从而阻止孕酮与孕酮受体的结合。醋酸乌利司他的药效依赖于月经周期中给药的时间。在卵泡增生中期给药会抑制卵泡生成和降低雌二醇浓度。乌利司他在促黄体激素高峰期给药可使卵泡延迟破裂5~9 天。黄体早期给药不能明显延迟子宫内膜成熟,但能够使子宫内膜厚度减少0.6±2.2mm(平均值±SD)。
【适应症】醋酸乌利司他用于120小时(5天)内无保护性交或避孕失败的紧急避孕。
【产品特点】
紧急避孕药亦称事后避孕药,是供育龄妇女无保护性交或避孕失败后使用以预防意外妊娠的应急性避孕药。目前,临床应用最广泛的紧急避孕药为左炔诺孕酮,以间隔12h各服1片(0.75mg)或单次服用2片(1.5mg)的方案用药。不过,左炔诺孕酮仅被批准在无保护性行为或避孕失败后72h内用作紧急避孕药。而醋酸乌利司他是120小时内用作紧急避孕药。即使如此,左炔诺孕酮的紧急避孕效力也会随用药时间延迟而明显下降,故被推荐最好在无保护性行为或避孕失败后12h内服药。醋酸乌利司他不仅可在无保护性行为或避孕失败后120h内服用,而且紧急避孕效力不会随用药时间延迟而下降,研究证实,妇女在性行为后第一天和第五天服用醋酸乌利司他紧急避孕药,效果一样。
2009年5月,欧盟批准了一种新型紧急避孕药醋酸乌利司他,临床试验表明该药具有良好的药效及安全性。
2010年8月13日,醋酸乌利司他(Ella)获美国FDA批准用于紧急事后避孕。安全性和耐受性均很好,醋酸乌利司他与目前最常用的紧急避孕药左炔诺孕酮相比,醋酸乌利司他具有预防更多意外妊娠的潜在益处,临床适用性更广。

Each tablet contains 237 mg of lactose (as monohydrate).
For the full list of excipients, see section 6.1
3. Pharmaceutical form
Tablet
White to marble creamy, round curved tablet engraved with code “еllа” on both faces
4. Clinical particulars
4.1 Therapeutic indications
Emergency contraception within 120 hours (5 days) of unprotected sexual intercourse or contraceptive failure.
4.2 Posology and method of administration
Posology
The treatment consists of one tablet to be taken orally as soon as possible, but no later than 120 hours (5 days) after unprotected intercourse or contraceptive failure.
ellaOne can be taken at any time during the menstrual cycle.
If vomiting occurs within 3 hours of ellaOne intake, another tablet should be taken.
If a woman's menstrual period is late or in case of symptoms of pregnancy, pregnancy should be excluded before ellaOne is administered.
Special populations
Renal impairment
No dose adjustment is necessary.
Hepatic impairment
In the absence of specific studies, no alternate dose recommendations for ellaOne can be made.
Severe hepatic impairment
In the absence of specific studies, ellaOne is not recommended.
Paediatric population
There is no relevant use of ellaOne for children of prepubertal age in the indication emergency contraception.
Adolescents: ellaOne is suitable for any woman of child bearing age, including adolescents. No differences in safety or efficacy have been shown compared to adult women aged 18 and older (see section 5.1).
Method of administration
Oral use.
The tablet can be taken with or without food.
4.3 Contraindications
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1
4.4 Special warnings and precautions for use
ellaOne is for occasional use only. It should in no instance replace a regular contraceptive method. In any case, women should be advised to adopt a regular method of contraception.
ellaOne is not intended for use during pregnancy and should not be taken by any woman suspected or known to be pregnant. However, ellaOne does not interrupt an existing pregnancy (see section 4.6).
ellaOne does not prevent pregnancy in every case.
In case the next menstrual period is more than 7 days late, if the menstrual period is abnormal in character or if there are symptoms suggestive of pregnancy or in case of doubt, a pregnancy test should be performed. As with any pregnancy, the possibility of an ectopic pregnancy should be considered. It is important to know that the occurrence of uterine bleeding does not rule out ectopic pregnancy. Women who become pregnant after taking ellaOne should contact their doctor (see section 4.6).
ellaOne inhibits or postpones ovulation (see section 5.1). If ovulation has already occurred, ellaOne is no longer effective. The timing of ovulation cannot be predicted and therefore ellaOne should be taken as soon as possible after unprotected intercourse.
No data are available on the efficacy of ellaOne when taken more than 120 hours (5 days) after unprotected intercourse.
Limited and inconclusive data suggest that there may be reduced efficacy of ellaOne with increasing body weight or body mass index (BMI) (see section 5.1). In all women, emergency contraception should be taken as soon as possible after unprotected intercourse, regardless of the woman's body weight or BMI.
After ellaOne intake menstrual periods can sometimes occur a few days earlier or later than expected. In approximately 7% of the women, menstrual periods occurred more than 7 days earlier than expected. In 18.5% of the women a delay of more than 7 days occurred, and in 4% the delay was greater than 20 days.
Concomitant use of ulipristal acetate and emergency contraception containing levonorgestrel is not recommended (see section 4.5).
Contraception after ellaOne intake
ellaOne is an emergency contraceptive that decreases pregnancy risk after unprotected intercourse but does not confer contraceptive protection for subsequent acts of intercourse. Therefore, after using emergency contraception, women should be advised to use a reliable barrier method until her next menstrual period.
Although the use of ellaOne does not contraindicate the continued use of regular hormonal contraception, ellaOne may reduce its contraceptive action (see section 4.5). Therefore, if a woman wishes to start or continue using hormonal contraception, she can do so after using ellaOne, however, she should be advised to use a reliable barrier method until the next menstrual period.
Specific populations
Concomitant use of ellaOne with CYP3A4 inducers is not recommended due to interaction (e.g. barbiturates (including primidone and phenobarbital), phenytoin, fosphenytoin, carbamazepine, oxcarbazepine, herbal medicines containing Hypericum perforatum (St. John's wort), rifampicin, rifabutin, griseofulvin, efavirenz, nevirapine and long term use of ritonavir).
Use in women with severe asthma treated by oral glucocorticoid is not recommended.
This medicinal product contains lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.
4.5 Interaction with other medicinal products and other forms of interaction
Potential for other medicinal products to affect ulipristal acetate
Ulipristal acetate is metabolized by CYP3A4 in vitro.
- CYP3A4 inducers
In vivo results show that the administration of ulipristal acetate with a strong CYP3A4 inducer such as rifampicin markedly decreases Cmax and AUC of ulipristal acetate by 90% or more and decreases ulipristal acetate half-life by 2.2-fold corresponding to an approximately 10-fold decrease of ulipristal acetate exposure. Concomitant use of ellaOne with CYP3A4 inducers (e.g. barbiturates (including primidone and phenobarbital), phenytoin, fosphenytoin, carbamazepine, oxcarbazepine, herbal medicines containing Hypericum perforatum (St. John's wort), rifampicin, rifabutin, griseofulvin, efavirenz and nevirapine) therefore reduces plasma concentrations of ulipristal acetate and may result in a decreased efficacy of ellaOne. For women who have used enzyme-inducing drugs in the past 4 weeks, ellaOne is not recommended (see section 4.4) and non-hormonal emergency contraception (i.e. a copper intrauterine device (Cu-IUD)) should be considered.
- CYP3A4 inhibitors
In vivo results show that administration of ulipristal acetate with a potent and a moderate CYP3A4 inhibitor increased Cmax and AUC of ulipristal acetate with a maximum of 2- and 5.9-fold, respectively. The effects of CYP3A4 inhibitors are unlikely to have any clinical consequences.
The CYP3A4 inhibitor ritonavir can also have an inducing effect on CYP3A4 when ritonavir is used for a longer period. In such cases ritonavir might reduce plasma concentrations of ulipristal acetate. Concomitant use is therefore not recommended (see section 4.4). Enzyme induction wears off slowly and effects on the plasma concentrations of ulipristal acetate may occur even if a woman has stopped taking an enzyme inducer in the past 4 weeks.
Medicinal products affecting gastric pH
Administration of ulipristal acetate (10 mg tablet) together with the proton pump inhibitor esomeprazole (20 mg daily for 6 days) resulted in approximately 65% lower mean Cmax, a delayed Tmax (from a median of 0.75 hours to 1.0 hours) and 13% higher mean AUC. The clinical relevance of this interaction for single dose administration of ulipristal acetate as emergency contraception is not known.
Potential for ulipristal acetate to affect other medicinal products
Hormonal contraceptives
Because ulipristal acetate binds to the progesterone receptor with high affinity, it may interfere with the action of progestogen-containing medicinal products:
- Contraceptive action of combined hormonal contraceptives and progestogen-only contraception may be reduced
- Concomitant use of ulipristal acetate and emergency contraception containing levonorgestrel is not recommended (see section 4.4).
In vitro data indicate that ulipristal acetate and its active metabolite do not significantly inhibit CYP1A2, 2A6, 2C9, 2C19, 2D6, 2E1, and 3A4, at clinically relevant concentrations. After single dose administration induction of CYP1A2 and CYP3A4 by ulipristal acetate or its active metabolite is not likely. Thus, administration of ulipristal acetate is unlikely to alter the clearance of medicinal products that are metabolised by these enzymes.
P-gp (P-glycoprotein) substrates
In vitro data indicate that ulipristal acetate may be an inhibitor of P-gp at clinically relevant concentrations. Results in vivo with the P-gp substrate fexofenadine were inconclusive. The effects of the P-gp substrates are unlikely to have any clinical consequences.
4.6 Fertility, pregnancy and lactation
Pregnancy
ellaOne is not intended for use during pregnancy and should not be taken by any woman suspected or known to be pregnant (see section 4.2).
ellaOne does not interrupt an existing pregnancy.
Pregnancy may occasionally occur after ellaOne intake. Although no teratogenic potential has been observed, animal data are insufficient with regard to reproduction toxicity (see section 5.3). Limited human data regarding pregnancy exposure to ellaOne do not suggest any safety concern. Nevertheless it is important that any pregnancy in a woman who has taken ellaOne be reported to www.hra-pregnancy-registry.com. The purpose of this web-based registry is to collect safety information from women who have taken ellaOne during pregnancy or who become pregnant after ellaOne intake. All patient data collected will remain anonymous.
Breast-feeding
Ulipristal acetate is excreted in breast milk (see section 5.2). The effect on newborn/infants has not been studied. A risk to the breastfed child cannot be excluded. After intake of ellaOne, breastfeeding is not recommended for one week. During this time it is recommended to express and discard the breast milk in order to stimulate lactation.
Fertility
A rapid return of fertility is likely following treatment with ellaOne for emergency contraception. Women should be advised to use a reliable barrier method for all subsequent acts of intercourse until the next menstrual period.
4.7 Effects on ability to drive and use machines
ellaOne may have minor or moderate influence on the ability to drive or use machines: mild to moderate dizziness is common after ellaOne intake, somnolence and blurred vision are uncommon; disturbance in attention has been rarely reported. The patient should be informed not to drive or use machines if they are experiencing such symptoms (see section 4.8).
4.8 Undesirable effects
Summary of the safety profile
The most commonly reported adverse reactions were headache, nausea, abdominal pain and dysmenorrhea.
Safety of ulipristal acetate has been evaluated in 4,718 women during the clinical development program.

Adolescents: the safety profile observed in women less than 18 years old in studies and post-marketing is similar to the safety profile in adults during the phase III program (Section 4.2).
Post-marketing experience: the adverse reactions spontaneously reported in post-marketing experience were similar in nature and frequency to the safety profile described during the phase III program.
Description of selected adverse reactions
The majority of women (74.6%) in the phase III studies had their next menstrual period at the expected time or within ± 7 days, while 6.8% experienced menses more than 7 days earlier than expected and 18.5% had a delay of more than 7 days beyond the anticipated onset of menses. The delay was greater than 20 days in 4 % of the women.
A minority (8.7%) of women reported intermenstrual bleeding lasting an average of 2.4 days. In a majority of cases (88.2%), this bleeding was reported as spotting. Among the women who received ellaOne in the phase III studies, only 0.4% reported heavy intermenstrual bleeding.
In the phase III studies, 82 women entered a study more than once and therefore received more than one dose of ellaOne (73 women enrolled twice and 9 enrolled three times). There were no safety differences in these subjects in terms of incidence and severity of adverse events, change in duration or volume of menses or incidence of intermenstrual bleeding.
Reporting of suspected adverse reactions
Reporting of suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via national reporting (see details below):

4.9 Overdose
Experience with ulipristal acetate overdose is limited. Single doses up to 200 mg have been used in women without safety concern. Such high doses were well-tolerated; however, these women had a shortened menstrual cycle (uterine bleeding occurring 2-3 days earlier than would be expected) and in some women, the duration of bleeding was prolonged, although not excessive in amount (spotting). There are no antidotes and further treatment should be symptomatic.
5. Pharmacological properties
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Sex hormones and modulators of the genital system, emergency contraceptives. ATC code: G03AD02.
Ulipristal acetate is an orally-active synthetic selective progesterone receptor modulator which acts via high-affinity binding to the human progesterone receptor. When used for emergency contraception the mechanism of action is inhibition or delay of ovulation via suppression of the LH surge. Pharmacodynamic data show that even when taken immediately before ovulation is scheduled to occur (when LH has already started to rise), ulipristal acetate is able to postpone follicular rupture for at least 5 days in 78.6% of cases (p<0.005 vs. levonorgestrel and vs. placebo) (see Table).

Ulipristal acetate also has high affinity for the glucocorticoid receptor and in vivo, in animals, antiglucocorticoid effects have been observed. However, in humans, no such effect has been observed even after repeat administration at the daily dose of 10 mg. It has minimal affinity to the androgen receptor and no affinity for the human estrogen or mineralocorticoid receptors.
Results from two independent randomized controlled trials (see Table) showed the efficacy of ulipristal acetate to be non-inferior to that of levonorgestrel in women who presented for emergency contraception between 0 and 72 hours after unprotected intercourse or contraceptive failure. When the data from the two trials were combined via meta- analysis, the risk of pregnancy with ulipristal acetate was significantly reduced compared to levonorgestrel (p=0.046).

Two trials provide efficacy data on ellaOne used up to 120 hours after unprotected intercourse. In an open-label clinical trial, which enrolled women who presented for emergency contraception and were treated with ulipristal acetate between 48 and 120 hours after unprotected intercourse, a pregnancy rate of 2.1% (26/1241) was observed. In addition, the second comparative trial described above also provides data on 100 women treated with ulipristal acetate from 72 to 120 hours after unprotected intercourse, in whom no pregnancies were observed.
Limited and inconclusive data from clinical trials suggest a possible trend for a reduced contraceptive efficacy of ulipristal acetate with high body weight or BMI (see section 4.4). The meta-analysis of the four clinical studies conducted with ulipristral acetate presented below excluded women who had further acts of unprotected intercourse.

5.2 Pharmacokinetic properties
Absorption
Following oral administration of a single 30 mg dose, ulipristal acetate is rapidly absorbed, with a peak plasma concentration of 176 ± 89 ng/ml occurring approximately 1 hour (0.5-2.0 h) after ingestion, and with an AUC0-∞ of 556 ± 260 ng.h/ml.
Administration of ulipristal acetate together with a high-fat breakfast resulted in approximately 45% lower mean Cmax, a delayed Tmax (from a median of 0.75 hours to 3 hours) and 25% higher mean AUC0-∞ compared with administration in the fasted state. Similar results were obtained for the active mono-demethylated metabolite.
Distribution
Ulipristal acetate is highly bound (>98%) to plasma proteins, including albumin, alpha-l-acid glycoprotein, and high density lipoprotein.
Ulipristal acetate is a lipophilic compound and is distributed in breast milk, with a mean daily excretion of 13.35 µg [0-24 hours], 2.16 µg [24-48 hours], 1.06 µg [48-72 hours], 0.58 µg [72-96 hours], and 0.31 µg [96-120 hours].
In vitro data indicate that ulipristal acetate may be an inhibitor of BCRP (Breast Cancer Resistance Protein) transporters at the intestinal level. The effects of ulipristal acetate on BCRP are unlikely to have any clinical consequences.
Ulipristal acetate is not a substrate for either OATP1B1 or OATP1B3.
Biotransformation/elimination
Ulipristal acetate is extensively metabolized to mono-demethylated, di-demethylated and hydroxylated metabolites. The mono-demethylated metabolite is pharmacologically active. In vitro data indicate that this is predominantly mediated by CYP3A4, and to a small extent by CYP1A2 and CYP2A6. The terminal half-life of ulipristal acetate in plasma following a single 30 mg dose is estimated to 32.4 ± 6.3 hours, with a mean oral clearance (CL/F) of 76.8 ± 64.0 L/h.
Special populations
No pharmacokinetic studies with ulipristal acetate have been performed in females with impaired renal or hepatic function.
5.3 Preclinical safety data
Non-clinical data reveal no special hazard for humans based on conventional studies of safety pharmacology, repeated dose toxicity, and genotoxicity. Most findings in general toxicity studies were related to its mechanism of action as a modulator of progesterone and glucocorticoid receptors, with antiprogesterone activity observed at exposures similar to therapeutic levels.
Information from reproductive toxicity studies is limited due to the absence of exposure measurement in these studies. Ulipristal acetate has an embryolethal effect in rats, rabbits (at repeated doses above 1 mg/kg) and in monkeys. At these repeated doses, the safety for a human embryo is unknown. At doses which were low enough to maintain gestation in the animal species, no teratogenic effects were observed.
Carcinogenicity studies (in rats and mice) showed that ulipristal acetate is not carcinogenic.

欧洲批准Esmya(ulipristal)用于子宫肌瘤
据WebMD Health News 2月1日报道,欧洲新的研究显示:一种新药似乎能有效缩小子宫肌瘤和控制因子宫肌瘤造成的严重经期出血。
在一项研究中,ulipristal acetate(醋酸乌利司他)被证明对缩小非恶性子宫肿比安慰剂有效。
在另一项研究中,醋酸乌利司他被发现减少子宫肌瘤的妇女严重出血与每月注射Lupron(leuprolide acetate,醋酸亮丙瑞林)同样有效,而较少潮热副作用。
这两项研究都将在2月2日出版的新英格兰医学杂志发表。
醋酸乌利司他是美国市售的紧急避孕药Ella的活性化学成分,但在这些研究中子宫肌瘤患者所摄取的每日剂量比那些避孕药中小。
Watson公司发言人查理·迈尔说,如果目前正在进行的试验得到肯定,它的公司将以Esmya商品名上市醋酸乌利司他治疗子宫肌瘤。相关数据显示,四分之一妇女患有子宫肌瘤症状。
