Efficacy Study of Prophylactic Ibuprofen Versus Placebo on Pain Relief and Success Rates of Medical Abortion

This study has been completed.

In the current study, we want to evaluate the prophylactic use of ibuprofen versus a placebo for medical abortion by mifepristone and misoprostol, at a gestational age of up to 7 weeks, in regard to the effect on pain relief and the overall procedure success.

expected results:

The prophylactic use of NSAIDs could offer significant pain relief and thereby a reduction in the need for additional pain relievers compared to the placebo, without interfering with the outcome of medical abortion

Condition Intervention Phase
Pain Pregnancy Drug: ibuprofen Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: The Effect of Prophylactic Ibuprofen Versus Placebo on Pain Relief and Success Rates of Medical Abortion: A Double-blind Randomized Placebo Controlled Study

Further study details as provided by Prof. Daniel Seidman, Sheba Medical Center:

Primary Outcome Measures:
  • • Decrease in pain as assessed using an 11-point numeric pain scale from 0 (= no pain) to 10 (=most severe pain). [ Time Frame: 2 weeks ]

Secondary Outcome Measures:
  • • Success of medical abortion as assessed by follow-up ultrasound examination and the frequency of surgical intervention was recorded. [ Time Frame: 2 weeks ]

Enrollment: 61
Study Start Date: October 2009
Study Completion Date: October 2010
Primary Completion Date: October 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: ibuprofen
the group will receive 2 tablets of ibuprofen 400 mg at the time of misoprostol administration. The information about the effect of the analgesics on the pain, and on the course of medical abortion, will be prospectively gathered from questionnaires completed by the study participants
Drug: ibuprofen
The most common side effect observed during medical abortion using mifepristone together with misoprostol is abdominal pain. The use of ibuprofen was not shown to interfere with the action of misoprostol to induce uterine contractions and pregnancy expulsion.
Other Name: ibuprofen - Nonsteroidal anti-inflammatory drugs (NSAIDs)
No Intervention: placebo
this group will receive 2 placebo tablets together with the misoprostol
