title: [A study on the optimal regimen of mifepristone with prostaglandin for termination of early pregnancy].
abstract: One thousand and thirty-five women in early pregnancy (< or = 49 days), who requested medical abortion were randomly allocated into 8 groups. Mifepristone and 15-methyt-PGF2 alpha vaginal suppository (PG05) and misoprostol oral (tablets) were given as the following 8 regimens: group 1 (n = 195): a single dose of mifepristone 200 mg + PG05 1 mg on the 3rd or 4th day; group 2 (n = 249): mifepristone 25 mg b.i.d. (total amount of 150mg) + PG05 1mg on the 3rd or 4th day; group 3 (n = 67): mifepristone 25 mg b.i.d. (total amount of 125mg) + PG05 1mg in the morning of the 3rd day; group 4 (n = 108): a single dose of mifepristone 200mg + misoprostol 600 micrograms on the 3rd day; group 5 (n = 199): a single dose of mifepristone 150mg + misoprostol 600 micrograms on the 3rd day; group 6 (n = 60): mifepristone 50 mg was given immediately, then 25 mg b.i.d. (total amount of 150mg + misoprostol 600 micrograms; group 7 (n = 123): mifepristone 50 mg in the morning and 25mg in the evening for two days (total amount of 150 mg) + misoprostol 600 micrograms; group 8 (n = 34): mifepristone 25 mg b.i.d. (total amount of 125mg) + misoprostol 400 micrograms. As a result, the complete abortion rate of each group was 92.8%, 95.2%, 92.5%, 93.5%, 87.4%, 98.4%, 92.7% and 94.1% successively. The rate of group 5 was significantly lower than that of group 2 and 6 (P < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
