Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Medical termination of pregnancy is a common and safe alternative to surgical termination of pregnancy(8). The current protocol in the investigators unit includes oral administration of Mifepristone 600 mg and oral Misoprostol 400 mcg in a time interval of 48 hours. There is little data to compare the efficacy of concomitant administration of both drugs and different time intervals.

This study evaluates the success rate and side effects of medical termination of pregnancy while both drugs are administrated concomitantly in comparison to interval of 48 hours between the drugs.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Medical termination of pregnancy is a common and safe alternative to surgical termination of pregnancy(8). According to the original protocol ,the administration of oral Mifepristone 600 mg is followed by oral Misoprostol 400 mcg in an interval of 36 to 48 hours. Shortening this time interval may convince patients to avoid surgical termination of pregnancy, enhance patient's compliance to treatment and even be more economically.

The current protocol in the investigators unit includes oral administration of Mifepristone 600 mg and oral Misoprostol 400 mcg in a time interval of 48 hours. The patients are recommended to have an ultrasound examination after 2 to 3 weeks. There is little data to compare the efficacy of concomitant administration of both drugs according to the dosage of this protocol and different time intervals.

This study evaluates the success rate and side effects of medical termination of pregnancy while both drugs are administrated concomitantly in comparison to interval of 48 hours between the drugs.

Participants in the study group will be given both drugs at the same time while participants in the control group will be given Mifepristone and Misoprostol in an interval of 48 hours.

The investigators hypothesis is that administration of both drugs concomitantly will not change significantly the success rate of the procedure and will not enhance the side effects.
