Summary

This trial tests whether a benzydamine throat spray, an anti-inflammatory pain reliever, can reduce sore throat after surgery that uses a breathing tube. About 106 women undergoing gynecological surgery will be randomly assigned to receive the spray or usual care. The study will compare how many women have a sore throat right after surgery and four hours later, as well as pain severity and any side effects.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
benzydamine hydrochloride spray
What this could lead to
If effective, this over-the-counter spray could become a simple, low-cost way to reduce throat pain after surgery, improving comfort during recovery.
What could go wrong
This is a small early-stage trial, so results may not apply to all patients. The spray may not reduce sore throat significantly, and some people might experience side effects like numbness or irritation.
