What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests whether misoprostol can reduce fluid loss during surgery to remove uterine fibroids, which are noncancerous growths in the uterus. Participants will receive either misoprostol or a placebo before their procedure. The trial aims to determine if misoprostol enhances surgical safety by controlling fluid levels. Women who require surgery for uterine fibroids, have fibroids between 1-3 cm, and are comfortable with the treatment method may be suitable for this trial. As a Phase 4 trial, this research focuses on understanding how this FDA-approved and effective treatment can benefit more patients.

Do I have to stop taking my current medications for the trial?

The trial information does not specify if you need to stop taking your current medications. However, it mentions that you can have been previously treated with certain medications like Depo-Lupron, Depo-Provera, or Oral Contraceptive pills, which suggests some medications might be allowed.

What is the safety track record for this treatment?

Previous studies have found misoprostol to be generally safe for patients. Research shows it primarily reduces blood loss during procedures by causing stronger uterine contractions, which help stop bleeding. As a result, patients typically lose less blood and experience smaller decreases in hemoglobin and hematocrit levels, key measures of blood health. Overall, the treatment is well-tolerated, with no major safety concerns reported in these studies. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Unlike the standard treatments for uterine fibroids, which often involve surgery or hormonal therapies, misoprostol offers a unique approach by being administered rectally. This method targets the fibroids directly, potentially reducing the need for more invasive procedures. Researchers are excited about misoprostol because it could provide a less invasive, more convenient alternative for patients, with fewer side effects compared to traditional surgical options.

What evidence suggests that misoprostol might be an effective treatment for uterine fibroids?

Research has shown that misoprostol can help reduce bleeding during uterine surgery. In one study, patients who used misoprostol needed fewer blood transfusions and experienced less bleeding during their procedures. Another study found that taking misoprostol before a fibroid removal procedure helped reduce postoperative pain. Misoprostol is also known to shrink fibroids, which are non-cancerous growths in the uterus. In this trial, participants will receive either misoprostol or a placebo before their procedure. These findings suggest that misoprostol could effectively manage symptoms related to fibroids and improve surgical outcomes. ^{1 4 6 7 8}

• Misoprostol

Trial Overview

The study tests if misoprostol reduces fluid loss compared to a placebo during surgery. Patients will be randomly given either 800 mcg of rectal misoprostol or placebo tablets before their operation in this double-blinded study.

How Is the Trial Designed?

Group I: Misoprostol (treatment aem) Experimental Treatment 1 Intervention

Patients will received 800 mcg of misoprostol per rectum prior to procedure.

Group II: Zeebo (Placebo arm) Placebo Group 1 Intervention

Patient will receive 4 tablets of placebo (ZEEBO) per rectum prior to procedure.
