This study is testing a new drug, ET-26, to see how well it helps put people to sleep for surgery. The trial will compare ET-26 to another drug called etomidate, which is already used for this purpose. **General anesthesia** means you're put into a deep sleep during surgery so you don't feel pain. **Multicenter** means the study happens in many places at once. **Randomized** means participants are chosen by chance to get either ET-26 or etomidate. **Double-blind** means neither the doctors nor the patients know which drug is being used, which helps keep the results fair.

Key Points:

• This study is for adults aged 18-70 who are having planned surgeries that need general anesthesia.
• Participants will be checked to ensure they are healthy enough for the study, with normal or safe levels of things like blood pressure and heart rate.
• Anyone allergic to the drugs, or with certain health conditions, can't participate.

If you join, you’ll need to follow the study rules closely, and you’ll get to help researchers learn more about a new way to put people to sleep for surgery.
