There are multiple interactions reported between these two agents.

Interaction Details

Aspirin, Omeprazole is classified as belonging to the following category: Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, phellodendron might increase serum levels of drugs metabolized by CYP2C9.
Phellodendron contains berberine. Preliminary clinical research shows that berberine can inhibit CYP2C9. Theoretically, phellodendron might also inhibit CYP2C9.

Aspirin, Omeprazole Overview

  • The combination of aspirin and omeprazole is used to reduce the risk of stroke or heart attack in patients who have had or are at risk of these conditions and are also at risk of developing a stomach ulcer when taking aspirin. Aspirin is in a class of medications called antiplatelet agents. It works by preventing platelets (a type of blood cell) from collecting and forming clots that may cause a heart attack or stroke. Omeprazole is in a class of medications called proton-pump inhibitors. It works by decreasing the amount of acid made in the stomach.
