Are there any other alternative sedatives to opioids that interact less with Valium dose?

Hi doctor,

I am going to undergo a laparoscopic fundoplication surgery after a week for severe GERD. For the past two months, I am taking Valium 5 mg for severe anxiety (mainly related to my health) three times daily. I am also taking Omeprazole 80 mg daily for several months.

I recently came across a study that stated the AUC and half-life of Valium are increased by 130 % with a dose of 40 mg Omeprazole. As I am taking double the dose of Omeprazole, I am afraid that it has raised my plasma level. I am concerned about the concurrent use of other drugs (opioids) that can help me.

I need to talk to an anesthesiologist before my surgery. Is this dangerous, or are there any other alternative sedatives to opiates that would interact less with my Valium dose? Is there any increased concentration in my body? This is my first major surgery, and I am terrified. I am taking Aspirin 81 mg and Crestor 10 mg. My past medications are Lorazepam, Citalopram, Escitalopram, Zoloft, Propranolol, Esomeprazole, and Ranitidine.
