Ulipristal Offers Alternative to Mifepristone in Abortions \ Newslooks \ Washington DC \ Mary Sidiqi \ Evening Edition \ A study suggests that the emergency contraceptive ulipristal acetate, at higher doses, could serve as an abortion drug, offering an alternative to mifepristone, which is under legal scrutiny. The research found the drug combination of ulipristal and misoprostol to be 97% effective for early abortion. Experts call for further studies before routine use.

Deep Look
A recent study has revealed that ulipristal acetate, the active ingredient in the emergency contraceptive pill Ella, could serve as an alternative abortion drug when administered at higher doses. The findings come at a critical time, as legal challenges and political debates over abortion access, particularly involving mifepristone, continue to escalate across the United States.
The study, published in NEJM Evidence, investigated whether ulipristal acetate could replicate mifepristone’s role in medication abortions. With mifepristone under intense legal scrutiny, researchers hope the study could provide an additional option for women seeking medication-based abortion care.
Mifepristone and Its Role in Medication Abortions
Mifepristone, used in approximately two-thirds of U.S. abortions, works by blocking progesterone, a hormone essential for maintaining a pregnancy. It is typically followed by a dose of misoprostol, a drug that induces uterine contractions and bleeding to complete the abortion process. Together, this combination is highly effective and widely regarded as safe by medical experts.
However, mifepristone has become a target for anti-abortion lawmakers, with several states pursuing federal court rulings to restrict or ban its use. This legal uncertainty has heightened the need for alternative abortion methods, prompting researchers to explore the potential of existing drugs like ulipristal acetate.
The Study: Ulipristal as an Alternative
The study focused on 133 women up to nine weeks pregnant, who were given a 60 mg dose of ulipristal acetate followed by a dose of misoprostol 24 hours later. Ulipristal acetate is already FDA-approved in lower doses (30 mg) as Ella, a prescription emergency contraceptive effective when taken within five days of unprotected sex.
The results were promising. The ulipristal-misoprostol combination successfully induced abortion in 97% of participants, matching the effectiveness of the mifepristone-misoprostol regimen. Only four women required additional procedures or medication to complete the process, highlighting the drug’s potential as a reliable alternative.
“This could be a game-changer,” said Dr. Beverly Winikoff, president of Gynuity Health Projects and the study’s lead author. “At least now we would have an alternative. I think it’s better to have more things that you could use.”
Implications for Reproductive Healthcare
The study’s findings come at a pivotal moment for reproductive healthcare in the United States. Since the Supreme Court’s decision to overturn Roe v. Wade in 2022, abortion access has been increasingly restricted, with medication abortion becoming a focal point for both advocates and opponents.
The availability of an alternative to mifepristone could be a significant development, ensuring continued access to medication abortion despite legal or political challenges. However, experts caution that more research is needed to fully understand ulipristal’s safety and efficacy as an abortion drug before it can be widely adopted.
Concerns About Potential Misuse of Study Findings
While the research represents a step forward, it has also raised concerns among reproductive health advocates. Dr. Daniel Grossman, an abortion researcher at the University of California, San Francisco, praised the study but warned of potential misuse of its findings by anti-abortion activists.
“I’m really worried that these results could be misapplied by anti-abortion activists to try to further their assault on contraception,” Grossman said, referencing the ongoing political battles over emergency contraception. Ella, the drug containing ulipristal acetate, is marketed as a contraceptive and is not intended to terminate an existing pregnancy.
The study’s publication could make emergency contraception a new target for opponents of abortion, who might seek to conflate its use with abortion to justify further restrictions.
Broader Context: Legal and Political Challenges
The study’s significance extends beyond its medical implications, as it intersects with broader legal and political challenges surrounding abortion access in the United States. Mifepristone’s availability has been contested in courtrooms, with opponents claiming safety concerns despite its decades-long track record of effective and safe use.
In contrast, ulipristal acetate is already widely used as an emergency contraceptive, which may make it less vulnerable to legal attacks. However, the potential for anti-abortion lawmakers to target ulipristal remains a concern.
New York-based Gynuity Health Projects, which led the study, views the findings as a critical step toward safeguarding abortion access. “Women need information about their options, especially at a time when mifepristone is under attack,” Winikoff said.
Expert Perspectives on the Path Forward
Despite the study’s encouraging results, experts stress that ulipristal acetate is not ready to replace mifepristone in medication abortions. Additional clinical trials are needed to assess its long-term safety and efficacy, particularly across diverse patient populations. Regulatory approvals and updated guidelines from medical organizations would also be required before ulipristal could be routinely prescribed for this purpose.
“While this study provides a potential backup option, it’s important to remember that mifepristone has been the gold standard for decades,” said Grossman. “Any new alternative will need to undergo rigorous evaluation before it can be adopted widely.”
Potential Impact on Patients and Providers
For patients, the availability of ulipristal acetate as an abortion drug could offer more flexibility, particularly in regions where access to mifepristone is restricted. For providers, having additional options could help mitigate the impact of legal and political pressures on abortion care.
“This is about ensuring that women have access to the care they need, no matter what obstacles they face,” Winikoff said. “Having more options is always better.”
A Critical Moment for Reproductive Health
The study’s findings highlight the importance of research and innovation in reproductive healthcare, especially in the face of mounting legal and political challenges. While ulipristal acetate shows promise as an alternative to mifepristone, its potential adoption underscores the need for ongoing advocacy to protect access to all forms of abortion care.
As legal battles over mifepristone continue, the results of this study offer hope for safeguarding reproductive rights in an increasingly uncertain landscape.
