Second-Trimester Medical Abortion with Misoprostol Preceded by Two Sequential Doses of Mifepristone: An Observational Study

Introduction

Based upon the pharmacokinetics of mifepristone, we postulated that repeating a dose after its half-life period may potentiate its abortifacient effect.

Methods

We administered mifepristone (200 mg) on days one and two, and misoprostol on day three (200 or 400 μg, vaginally, six-hourly, upto three doses in 12 h) in 100 women (intervention group). We compared their outcome with that of another 100 women who received the one-dose mifepristone regimen (mifepristone on day one and misoprostol on day three) during the months immediately preceding the study period (historical controls).

Results

The mean age, parity and gestation (18 weeks) were similar in the two groups. On day three (before initiating misoprostol), cervix admitted one finger in significantly more women in the intervention group (36 versus 8% in historical controls; p = 0.001). All women aborted successfully in the two groups. The IAI of the intervention group was significantly shorter than the IAI of historical controls (10.45 vs 13.75 h; p = 0.013), and the misoprostol requirement was also significantly lower (mean 434 vs 500 μg among historical controls, p = 0.04).

Conclusions

Second-trimester medical abortion using two sequential doses of mifepristone followed by misoprostol reduced the IAI and misoprostol requirement without adding any extra days to the existing regimen. Further randomized studies can assess if the 'two-dose' mifepristone regimen is more efficient than the 'one-dose' regimen.

Second trimester medical abortion in a primigravida with lupus nephritis and rapidly progressive renal failure: challenges and outcome

In the second trimester, medical abortion is preferred as it is less invasive, and the surgical method carries more risk. There is a paucity of published literature on medical abortion in women with renal failure requiring haemodialysis. We came across a woman who presented with rapidly progressive renal failure at 18 weeks of gestation and required therapeutic abortion. We are reporting the challenges, outcomes, and precautions to be taken while performing a medical abortion in such a case.
