Title: Improving the Effectiveness of Emergency Contraception with Levonorgestrel Plus Piroxicam
Introduction:
Emergency contraception provides women with a valuable option to prevent unintended pregnancies after unprotected sexual intercourse. Levonorgestrel, a first-line oral emergency contraceptive pill, has been widely used for this purpose. In a recent study published in The Lancet, researchers explored the potential of adding oral piroxicam, a nonsteroidal anti-inflammatory drug (NSAID) and cyclooxygenase enzyme inhibitor, to levonorgestrel to enhance its efficacy without increasing adverse outcomes.
Key Findings from the Study:
The study involved 860 women who received levonorgestrel within 72 hours of unprotected sexual intercourse. They were randomly assigned to receive a single supervised dose of 1.5 mg levonorgestrel plus 40 mg oral piroxicam or 1.5 mg levonorgestrel plus a placebo. The researchers followed up with the participants 1 to 2 weeks after their next expected period to determine pregnancy status.
The results showed that the combination of levonorgestrel plus piroxicam significantly decreased the chance of pregnancy compared to levonorgestrel plus placebo. Only 0.2% of women who received levonorgestrel plus piroxicam became pregnant, while 1.7% of women who received levonorgestrel plus placebo experienced pregnancy. This translates to a 94.7% prevention of expected pregnancies with levonorgestrel plus piroxicam, compared to 63.4% with levonorgestrel plus placebo.
Furthermore, the study found no significant difference between the two groups in terms of adverse events or changes in menstrual patterns. Both groups reported similar rates of fatigue or weakness, nausea, lower abdominal pain, dizziness, and headaches.
The Mechanism of Action:
The researchers hypothesize that piroxicam, as an inhibitor of the cyclooxygenase enzyme involved in prostaglandin production, might act synergistically with levonorgestrel to improve the effectiveness of emergency contraception. Prostaglandins play a crucial role in various reproductive processes, including ovulation, fertilization, tubal function, and embryo implantation. By inhibiting the production of prostaglandins, piroxicam may help regulate ovulation and post-ovulatory processes, thereby reducing the chance of pregnancy.
Implications and Recommendations:
Based on the study findings, the researchers suggest that adding piroxicam to levonorgestrel may be considered when emergency contraception is chosen. However, further studies are needed to validate these results and determine the strength of this recommendation. If reproducible, these findings could lead to changes in clinical guidelines for emergency contraception, improving the options available for women in need.
Additional Insights and Perspectives:
While the study provides encouraging results regarding the effectiveness of levonorgestrel plus piroxicam, it is essential to consider the broader context of emergency contraception. Emergency contraception plays a crucial role in reproductive health, allowing women to have control over their fertility and prevent unintended pregnancies. Therefore, ongoing research and innovation in this field are vital.
One aspect that future studies could explore is the potential impact of levonorgestrel plus piroxicam on other variables related to emergency contraception. For example, researchers could investigate the impact of this combination on the timing and predictability of ovulation after unprotected intercourse. Understanding the effects on ovulation could shed light on the optimal timing for initiating emergency contraception and enhance its overall efficacy.
Moreover, exploring potential differences in efficacy among different subgroups of women, such as age or body mass index, would be valuable. By identifying any variations in effectiveness, healthcare providers can tailor their recommendations and ensure that all women have access to the most suitable form of emergency contraception for their specific circumstances.
Conclusion:
The study’s findings provide evidence that the addition of piroxicam to levonorgestrel improves the efficacy of emergency contraception without increasing the risk of adverse outcomes. This combination could offer women an enhanced option for preventing unintended pregnancies after unprotected sexual intercourse. While further research is needed to corroborate these findings and guide clinical guidelines, the study represents an important step forward in expanding the choices available for reproductive healthcare.
Summary:
The addition of piroxicam, an NSAID and cyclooxygenase enzyme inhibitor, to levonorgestrel, a first-line oral emergency contraceptive pill, improves the efficacy of emergency contraception without increasing adverse outcomes, according to a recent study. The combination of levonorgestrel plus piroxicam significantly decreased the chance of pregnancy in women who received it compared to those who received levonorgestrel plus placebo. Furthermore, no significant differences in adverse events or changes in menstrual patterns were observed between the groups. These findings suggest that levonorgestrel plus piroxicam could be a valuable option for emergency contraception, pending further research to validate and refine its use.

Key takeaways:
- Women who received levonorgestrel plus piroxicam had a lower chance of pregnancy than those who received levonorgestrel plus placebo.
- Overall, levonorgestrel plus piroxicam prevented 94.7% of expected pregnancies.
Oral piroxicam given together with levonorgestrel improved the effectiveness of emergency contraception without increasing the risk of adverse outcomes, according to trial data published in The lancet.
Piroxicam is an NSAID and a cyclooxygenase enzyme inhibitor, while levonorgestrel is a first-line oral emergency contraceptive pill.
“Prostaglandins facilitate several reproductive processes, including ovulation, fertilization, tubal function, and embryo implantation.” Raymond Hang Wun Li, doctor, from the department of obstetrics and gynecology, Faculty of Clinical Medicine, University of Hong Kong and the Hong Kong Family Planning Association, and colleagues. “Therefore, it is possible that an inhibitor of the enzyme cyclooxygenase, the key enzyme involved in prostaglandin production, could act synergistically with emergency oral contraceptive methods to improve their effectiveness in regulating ovular and post-ovular processes.”
Li and colleagues conducted a randomized, double-blind, placebo-controlled trial of 860 women who received levonorgestrel within 72 hours of unprotected sexual intercourse between August 2018 and August 2022 at a large community-based sexual and health service. reproduction in Hong Kong. All participants were randomly assigned to a single supervised dose of 1.5 mg levonorgestrel plus 40 mg oral piroxicam (n = 430; mean age, 31 years) or 1.5 mg levonorgestrel plus placebo (n = 430; average age, 30 years).
The researchers followed up all participants 1 to 2 weeks after their next expected period and obtained pregnancy status by history or pregnancy test. The primary efficacy outcome was the proportion of pregnancies averted.
Compared with 1.7% of women receiving levonorgestrel plus placebo, 0.2% of women receiving levonorgestrel plus piroxicam became pregnant during follow-up (OR = 0.2; 95% CI, 0.02 -0.91; P= .036). Levonorgestrel 1.5 mg plus piroxicam 40 mg prevented 94.7% of expected pregnancies compared to 63.4% of pregnancies prevented with levonorgestrel 1.5 mg plus placebo.
Additionally, researchers found no significant difference between those who received piroxicam and those who received placebo in the proportion of women who had their next period earlier or later by more than 7 days (25% for the piroxicam group vs. 23% for the placebo) or adverse events including fatigue or weakness (10% for the piroxicam group versus 12% for placebo), nausea (8% for both groups), lower abdominal pain (7% for both groups), dizziness (6% for both groups) and headache (5% for the piroxicam group vs. 6% for the placebo group).
“[Piroxicam plus levonorgestrel] “It may be considered when emergency contraception with levonorgestrel is the option of choice,” the researchers wrote. “The strength of this recommendation and changes to clinical guidelines can be determined upon demonstration of reproducible results in additional studies.”
