|Active Comparator: A||
mifepristone 200 mg followed by 200 µg misoprostol per vaginam 36- 48 hours later at 4 hourly intervals (with a maximum of 10 administrations in 48 hours) until the foetus was delivered.
|Active Comparator: B||
mifepristone 200 mg followed by 400 µg misoprostol per vaginam 36- 48 hours later at 4 hourly intervals (with a maximum of 10 administrations in 48 hours) until the foetus was delivered.
