Medication regimens using mifepristone and misoprostol are safe and effective for outpatient treatment of early pregnancy loss for up to 84 days' gestation and for medication abortion up to 77 days' gestation. Gestational age is determined using ultrasonography or menstrual history. Ultrasonography is needed when gestational dating cannot be confirmed using clinical data alone or when there are risk factors for ectopic pregnancy. The most effective regimens for medication management of early pregnancy loss and medication abortion include 200 mg of oral mifepristone (a progesterone receptor antagonist) followed by 800 mcg of misoprostol (a prostaglandin E1 analogue) administered buccally or vaginally. Cramping and bleeding are expected effects of the medications, with bleeding lasting an average of nine to 16 days. The adverse effects of misoprostol (e.g., low-grade fever, gastrointestinal symptoms) can be managed with nonsteroidal anti-inflammatory drugs or antiemetics. Ongoing pregnancy, infection, hemorrhage, undiagnosed ectopic pregnancy, and the need for unplanned uterine aspiration are rare complications. Clinical history, combined with serial quantitative beta human chorionic gonadotropin levels, urine pregnancy testing, or ultrasonography, is used to establish complete passage of the pregnancy tissue.

Meta-Analysis Review
BACKGROUND
Uterine fibroids are the most common benign uterine tumours present in women of reproductive age. Mifepristone (RU-486) competitively binds and inhibits progesterone receptors. Studies have suggested that fibroid growth depends on the sexual steroids. Mifepristone has been shown to decrease fibroid size. This review summarises the effects of mifepristone treatment on fibroids and the associated adverse effects as described in randomised controlled trials.
OBJECTIVES
To determine the efficacy and safety of mifepristone for the management of uterine fibroids in pre-menopausal women.
SEARCH METHODS
We searched the specialised register of the Cochrane Menstrual Disorders and Subfertility (Cochrane Menstrual Disorders and subfertility Review Group), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 4), MEDLINE, EMBASE, PsycINFO, and CINAHL (to November 2011). We handsearched a number of journals, and searched reference lists, databases of ongoing trials and the Internet. There were no language restrictions.
SELECTION CRITERIA
Only truly randomised controlled trials of mifepristone versus other forms of medical therapy or placebo in pre-menopausal women with confirmed uterine fibroids were included.
DATA COLLECTION AND ANALYSIS
Four authors independently extracted data and assessed trial quality. Data were analysed using the Peto odds ratios (OR) for dichotomous data and the weighted mean differences for continuous data, with 95% confidence intervals (CI). Meta-analyses were performed using the fixed-effect model.
MAIN RESULTS
Three studies involving 112 participants were included. Comparison interventions included different dosages of mifepristone, placebo and vitamin B tablets. There is evidence that treatment with mifepristone relieves heavy menstrual bleeding compared with placebo (Peto OR 17.84; 95% CI 6.72 to 47.38; 2 RCTs, 77 women, I(2) = 0%). Three studies (Bagaria 2009; Engman 2009; Fiscella 2006) were included in the meta-analysis of this comparison. There was no evidence of an effect of mifepristone on the fibroid volume (standardised mean difference (SMD) -0.02; 95% CI -0.38 to 0.41; 99 women). Two studies (Bagaria 2009; Fiscella 2006) were included in the meta-analysis of this comparison. There was no evidence of an effect of mifepristone on uterine volume (mean difference (MD) -77.24; 95% CI -240.62 to 86.14; 72 women). The pooled data suggest an increased adverse event (abnormal endometrial histology) in the mifepristone group compared to placebo (OR 31.65; 95% CI 4.83 to 207.35; 2 RCTs; 54 women; I(2) = 0%). Only one study (Bagaria 2009) reported endometrial hyperplasia at the end of the therapy (12/19 women in the mifepristone group versus 0/16 in the placebo group; OR 55.0; 95% CI 2.86 to 105.67). Engman 2009 found a significantly higher rate of cystic glandular dilatation in women in the mifepristone group (5/8 women biopsied) compared with the placebo group (1/11 women biopsied) (OR 16.67; 95% CI 1.36 to 204.03). One study (Fiscella 2006) suggested significant improvements (P < 0.001) for specific quality of life outcomes.
AUTHORS' CONCLUSIONS
Mifepristone reduced heavy menstrual bleeding and improved fibroid-specific quality of life. However, it was not found to reduce fibroid volume. Further well-designed, adequately powered RCTs are needed before a recommendation can be made on the use of mifepristone for the treatment of uterine fibroids.

Randomized Controlled Trial
OBJECTIVE
The most commonly used approved indications for mifepristone in obstetrics include: termination of early pregnancy, cervical dilatation prior to abortion, labour induction in case of fetal death in utero. Fewer studies have been conducted on the effect of mifepristone on cervical ripening and induction of labour in term pregnancy with a live fetus. The aim of our study was to evaluate efficacy and safety of mifepristone use for cervical ripening and induction of labour versus expectant management in full-term pregnancy.
STUDY DESIGN
Randomized controlled trial. 149 women were randomized, 74 for cervical ripening and induction with mifepristone (200mg orally at the moment of enrollment and, if applicable, second dose after 24h), 75 - expectant management. Primary outcomes: gain in Bishop Score within 24 and 48-h of mifepristone; number of women going into spontaneous labor within 24, 48 and 72-h of mifepristone; rate of failed induction or expectant management.
SECONDARY OUTCOMES
enrollment-induction to delivery interval; mode of delivery; requirement of oxytocin augmentation, neonatal outcomes.
RESULTS
After 48h from enrollment mean gain in Bishop score was 2.58±1.33 in the induction group and 1.15±0.97 in the expectant group (<0.001). Failed management rate was 5.41% and 2.67%, respectively. Significantly more mifepristone treated women had labour within 24, 48 and 72h from enrollment (RR 15.20 CI 95% 2.06-112.18; RR 6.08 CI 95% 2.73-13.57; RR 2.14 CI 95% 1.04-4.42) (p<0.05). Enrollment-induction to delivery interval was significantly shorter in mifepristone group: 2.69±2.06 vs 3.77±1.86days (p<0.001). Premature rupture of membranes, meconium-stained amniotic fluid were more common in expectant management, but regional analgesia and cephalopelvic disproportion - in induction group. There were no differences in mode of delivery, requirement of oxytocin augmentation and main neonatal outcomes.
CONCLUSION
Mifepristone was efficient on inducing cervical ripening and labour in full-term pregnancy. There were no significant difference in main maternal and neonatal outcomes between mifepristone use and expectant management. There were no serious adverse side effects of mifepristone, but there were some features of the course of labor, like more painful uterine contractions and trend of higher rate of cephalopelvic disproportion, that might be directly related to the mifepristone action.

Randomized Controlled Trial
IMPORTANCE
To date, no psychopharmacologic treatment has been found to be uniformly effective in veterans with posttraumatic stress disorder (PTSD); novel targets and approaches are needed to treat this disabling disorder.
OBJECTIVE
To examine whether treatment with the glucocorticoid receptor antagonist mifepristone yields a signal for clinical efficacy in male veterans with PTSD.
DESIGN, SETTING, AND PARTICIPANTS
This phase 2a, double-blind, parallel-group randomized clinical trial was conducted from November 19, 2012 (accrual started), through November 16, 2016 (final follow-up), within the US Department of Veterans Affairs. Participants were male veterans with chronic PTSD and a screening Clinician-Administered PTSD Scale score of 50 or higher. A total of 181 veterans consented to participation. Statistical analysis was conducted between August 2014 and May 2017.
INTERVENTIONS
Participants were randomized in a 1:1 ratio to mifepristone (600 mg) or matched placebo taken orally for 7 days.
MAIN OUTCOMES AND MEASURES
The clinical outcome was whether a veteran achieved a clinical response status (a reduction of ≥30% of total Clinician-Administered PTSD Scale score from baseline) at 4- and 12-week follow-up. On the basis of a binary statistical selection rule, a difference in the proportion of treatment vs control group responders of 15% would be a clinically relevant difference. Self-report measures of PTSD and associated symptoms were also obtained. Neuroendocrine outcomes and plasma levels of mifepristone were measured. Safety was assessed throughout the study. The primary analysis was based on a multiple imputation technique to address missing outcome data; thus, some participant numbers may not appear as whole numbers.
RESULTS
A total of 81 veterans were enrolled and randomized. Excluding 1 participant randomized in error, 80 were included in the modified intention-to-treat analysis (41 randomized to mifepristone and 39 to placebo). The mean (SD) age was 43.1 (13.7) years. A total of 15.6 (38.1%) in the mifepristone group and 12.1 (31.1%) in the placebo group were clinical responders at 4 weeks in the analysis using the multiple imputation technique. The group difference in the proportion of clinical responders (7.0%) was less than the predefined margin of 15% indicating signal for clinical efficacy. In an exploratory analysis, the difference in response to mifepristone vs placebo in the subgroup with no lifetime history of traumatic brain injury (TBI) (7.0 [50.0%] vs 3.0 [27.3%]; difference, 22.7%) exceeded the efficacy margin at 4 weeks and was sustained at 12 weeks. In contrast, in veterans with PTSD and lifetime TBI, the response rate to mifepristone was lower than placebo at 12 weeks (7.4 [27.4%] vs 13.5 [48.3%]; difference, -20.9%).
CONCLUSIONS AND RELEVANCE
This study did not detect a signal for efficacy for mifepristone at 600 mg/d for 1 week in male veterans with chronic PTSD. Thus, this study does not support a phase 3 trial in this population. Future studies of mifepristone for the treatment of PTSD may be of interest in those without a history of TBI or in samples with a low base rate of lifetime head trauma.

Review
OBJECTIVE
To review the literature concerning the mechanism of action and pharmacodynamics of mifepristone (RU486), potential new uses of RU486, and its current use not only as an abortifacient but also as therapy for endometriosis, leiomyoma, breast cancer, and meningioma.
DATA IDENTIFICATION AND SELECTION
Studies that relate to RU486 were identified through a MEDLINE search.
CONCLUSION(S)
RU486 is an 11 beta-dimethyl-amino-phenyl derivative of norethindrone with a high affinity for P and glucocorticoid receptors. The receptor binding is not followed by transcription of P-dependent genes. Mifepristone effectively blocks P receptors in the placenta, resulting in the termination of pregnancy. In addition, it has been used in the treatment of leiomyomata, endometriosis, advanced breast cancer, and meningioma. It is a powerful tool to study the molecular action of P and in the future may be used as an estrogen-free contraceptive.

Observational Study
IMPORTANCE
Misoprostol-alone regimens for abortion may be more effective than previously thought.
OBJECTIVE
To estimate the effectiveness of medication abortion with misoprostol alone among individuals self-managing their abortion.
DESIGN, SETTING, AND PARTICIPANTS
For this prospective observational cohort study of callers to safe abortion hotlines and accompaniment groups in Argentina, Nigeria, and Southeast Asia, participants were recruited between July 31, 2019, and October 1, 2020, prior to starting their medication abortion. Eligible participants were 13 years or older, had no contraindications to medication abortion, and were not currently bleeding. Participants completed a baseline and 2 follow-up surveys. The analysis was restricted to participants who reported using misoprostol alone and was performed between January 6, 2022 and September 8, 2023.
EXPOSURE
Self-managed medication abortion using misoprostol alone.
MAIN OUTCOMES AND MEASURES
The primary outcome was effectiveness, defined as participant self-report of complete abortion without procedural intervention, measured at 1 week and 3 weeks after taking misoprostol. Secondary outcomes included method safety, measured by self-report of experiencing warning signs (eg, heavy bleeding, pain, fever, discharge) indicative of a potential complication and by medical treatment (eg, blood transfusion, intravenous fluids, overnight hospital stay) indicative of a potential adverse event. Additional outcomes included length of bleeding and cramping, time to expulsion, and experience of adverse effects.
RESULTS
Among 1352 enrolled participants, 637 used misoprostol-alone regimens for abortion and were included in the analysis (591 [92.8%] from Nigeria, 45 [7.1%] from Southeast Asia, and 1 [0.2%] from Argentina; 384 [60.2%] aged 20-29 years; 317 [49.8%] with pregnancy durations <7 weeks and 205 [32.2%] with pregnancy durations between 7 and <9 weeks). At last follow-up after taking medication (median, 22 days; IQR, 21-26 days), 625 participants (98.1%; 95% CI, 96.7%-98.9%) had a complete abortion without procedural intervention. Potential adverse events were reported by 6 participants (0.9%; 95% CI, 0.4%-2.1%). Most participants experienced bleeding for less than 1 week (median, 4 days; IQR, 3-6 days) and expelled their pregnancy within 24 hours of starting the abortion process (median, 12 hours; IQR, 9-15 hours). Common side effects included nausea (335 participants [52.6%]), fever (232 [36.4%]), and diarrhea (181 [28.4%]).
CONCLUSIONS AND RELEVANCE
The findings suggest that misoprostol alone is a highly effective method of pregnancy termination. Future research should explore strategies to maximize the effectiveness of misoprostol alone in clinical and nonclinical settings.

ETHNOPHARMACOLOGICAL RELEVANCE
Threatened abortion is a common disease among women of childbearing age. Its high incidence rate and unclear etiology, seriously threaten women's physical and mental health. Shoutai Wan (STW) is a traditional Chinese medicine decoction for treating abortion. It has a long history of treating threatened abortion by tonifying the kidney and calming the fetus. However, the mechanism of STW remains unclear.
AIM OF STUDY
To study the mechanism and potential benefit of STW in pregnant mice with hydrocortisone and mifepristone-induced threatened abortion.
MATERIALS AND METHODS
The STW compounds were identified using gas chromatography-mass spectrometry analysis. STW-H, STW-M, or STW-L was separately given 3 mg/ml, 1.5 mg/ml and 0.75 mg/ml STW in the morning, and 2 mg/ml hydrocortisone in the afternoon from gestation day (D) 1-9 and once with 0.4 mg/kg mifepristone on D10. Didroxyprogesterone (0.1 mg/ml) and equal dose pure water were used to replace STW in didroxyprogesterone (DYD) group and model group respectively. The control group used pure water to replace STW, hydrocortisone, and mifepristone. We performed morphological and histological analyses of the maternal-fetal interface on day 10.
RESULTS
The embryo loss rate in the STW-H and DYD groups was lower than that in the model group. Hematoxylin and eosin (HE) staining suggested that the morphology of maternal-fetal interface was improved in the STW-H and DYD groups. Immunohistochemical (IHC), Quantitative Reverse Transcription Polymerase Chain Reactionstaining (qRT-PCR), and Western blot (WB) results indicated that HIF-1α expression in the maternal-fetal interface of the STW-H and DYD groups was higher than that in model group. The activities of HK, PKM, LDH and the concentration of lactic acid in the STW-H and DYD groups were higher than those in model group. Furthermore, the protein and mRNA levels of HK2, PKM2, LDHA, MCT4, and GPR81 were higher in the STW-H and DYD groups than those in the model group.
CONCLUSIONS
STW can reduce the pregnancy loss rate by regulating the glycolysis balance at the maternal-fetal interface of kidney deficiency threatened abortion model mice.

Review
A fetus may survive an intentional interference with its intrauterine environment (1) if gestational age is mistaken and the procedure of induced abortion does not kill the fetus, (2) if a change of heart takes place after abortifacient drugs are taken and the abortion does not proceed, and (3) if a high-multiple pregnancy is reduced to a singleton or a twin pregnancy to improve the likelihood that the remaining fetuses will reach viability. In each case, through cause or coincidence, an abnormal baby may be born. The well-intentioned physician, responding to a patient's medical or psychological needs, risks a legal action in negligence or assault brought by a deformed surviving child. This hazard means that medical termination of pregnancy and selective pregnancy reduction put the practising physician at substantial risk in a way not usually associated with induced abortion.

BACKGROUND
The U.S. Food and Drug Administration (FDA) restricts dispensing of mifepristone for medication abortion to certified health care providers at clinical facilities, thus prohibiting pharmacist dispensing. Allowing mifepristone dispensing by pharmacists could improve access to medication abortion.
OBJECTIVE
To assess the feasibility of pharmacists dispensing mifepristone to patients who have undergone evaluation for eligibility and counseling for medication abortion by a clinician.
METHODS
Before providing a study training on medication abortion, we administered baseline surveys to pharmacists who participated in a multisite mifepristone-dispensing intervention. The survey assessed medication abortion knowledge-using a 15-item score-and perceptions about the benefits and challenges of the model. We administered follow-up surveys in the study's final month that also assessed the pharmacists' satisfaction and experiences with mifepristone dispensing. To investigate the association of the study intervention with the pharmacists' knowledge, perceptions, and experiences dispensing mifepristone, we conducted multivariable linear regression analyses using generalized estimating equation models, accounting for clustering by individual.
RESULTS
Among the 72 pharmacists invited from 6 pharmacies, 47 (65%) completed the baseline surveys, and 56 (78%) received training. At the study's end (mean 18 months later), 43 of the 56 pharmacists who received training (77%) completed the follow-up surveys. At follow-up, 36 (83%) respondents were very or somewhat satisfied with mifepristone dispensing, and 24 (56%) reported experiencing no challenges dispensing mifepristone. Four (6%) of the 72 pharmacists invited objected to participating in mifepristone dispensing. In regression analyses, average knowledge scores, perceived ease of implementation, and level of support for the pharmacist-dispensing model were higher at follow-up (P < 0.001).
CONCLUSION
Most pharmacists were willing to be trained, dispensed mifepristone with few challenges when given the opportunity, were satisfied with the model, and had higher knowledge levels at follow-up. Our findings support removal of FDA's restriction on pharmacist dispensing of mifepristone.

Randomized Controlled Trial
TRIAL DESIGN
A randomised, parallel-group, double-blind, placebo-controlled multicentre study with health economic and nested qualitative studies to determine if mifepristone (Mifegyne, Exelgyn, Paris, France) plus misoprostol is superior to misoprostol alone for the resolution of missed miscarriage.
METHODS
Women diagnosed with missed miscarriage in the first 14 weeks of pregnancy were randomly assigned (1 : 1 ratio) to receive 200 mg of oral mifepristone or matched placebo, followed by 800 μg of misoprostol 2 days later. A web-based randomisation system allocated the women to the two groups, with minimisation for age, body mass index, parity, gestational age, amount of bleeding and randomising centre. The primary outcome was failure to pass the gestational sac within 7 days after randomisation. The prespecified key secondary outcome was requirement for surgery to resolve the miscarriage. A within-trial cost-effectiveness study and a nested qualitative study were also conducted. Women who completed the trial protocol were purposively approached to take part in an interview to explore their satisfaction with and the acceptability of medical management of missed miscarriage.
RESULTS
A total of 711 women, from 28 hospitals in the UK, were randomised to receive either mifepristone plus misoprostol (357 women) or placebo plus misoprostol (354 women). The follow-up rate for the primary outcome was 98% (696 out of 711 women). The risk of failure to pass the gestational sac within 7 days was 17% (59 out of 348 women) in the mifepristone plus misoprostol group, compared with 24% (82 out of 348 women) in the placebo plus misoprostol group (risk ratio 0.73, 95% confidence interval 0.54 to 0.98; = 0.04). Surgical intervention to resolve the miscarriage was needed in 17% (62 out of 355 women) in the mifepristone plus misoprostol group, compared with 25% (87 out of 353 women) in the placebo plus misoprostol group (risk ratio 0.70, 95% confidence interval 0.52 to 0.94; = 0.02). There was no evidence of a difference in the incidence of adverse events between the two groups. A total of 42 women, 19 in the mifepristone plus misoprostol group and 23 in the placebo plus misoprostol group, took part in an interview. Women appeared to have a preference for active management of their miscarriage. Overall, when women experienced care that supported their psychological well-being throughout the care pathway, and information was delivered in a skilled and sensitive manner such that women felt informed and in control, they were more likely to express satisfaction with medical management. The use of mifepristone and misoprostol showed an absolute effect difference of 6.6% (95% confidence interval 0.7% to 12.5%). The average cost per woman was lower in the mifepristone plus misoprostol group, with a cost saving of £182 (95% confidence interval £26 to £338). Therefore, the use of mifepristone and misoprostol for the medical management of a missed miscarriage dominated the use of misoprostol alone.
LIMITATIONS
The results from this trial are not generalisable to women diagnosed with incomplete miscarriage and the study does not allow for a comparison with expectant or surgical management of miscarriage.
FUTURE WORK
Future work should use existing data to assess and rank the relative clinical effectiveness and safety profiles for all methods of management of miscarriage.
CONCLUSIONS
Our trial showed that pre-treatment with mifepristone followed by misoprostol resulted in a higher rate of resolution of missed miscarriage than misoprostol treatment alone. Women were largely satisfied with medical management of missed miscarriage and would choose it again. The mifepristone and misoprostol intervention was shown to be cost-effective in comparison to misoprostol alone.
