Interaction Details
Rabeprazole is classified as belonging to the following category: Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, danshen may increase the levels and clinical effects of drugs metabolized by CYP2C9.
In vitro research shows that various constituents of danshen inhibit the activity of CYP2C9. So far, this interaction has not been reported in humans.
Interaction Rating
Likelihood of Occurrence
PossibleInteraction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists

Interaction Details
Rabeprazole is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates
Danshen might alter the levels and clinical effects of drugs metabolized by CYP3A4.
Preliminary clinical research in healthy males shows that the administration of danshen for 10-14 days induces intestinal CYP3A4 and increases the clearance of midazolam, a CYP3A4 substrate. The maximum concentration of midazolam was decreased by 31% to 67%, and drug levels were decreased by 27% to 80%. However, a single dose of danshen has the opposite effect, increasing maximum concentrations of midazolam by 87%.

Danshen Overview

Rabeprazole Overview
-
Rabeprazole is used to treat the symptoms of gastroesophageal reflux disease (GERD), a condition in which backward flow of acid from the stomach causes heartburn and possible injury of the esophagus (the tube that connects the throat and stomach) in adults and children 12 year of age and older. Rabeprazole is used to treat damage from GERD, allow the esophagus to heal, and prevent further damage to the esophagus in adults. Rabeprazole is also used to treat conditions in which the stomach produces too much acid, such as Zollinger-Ellison syndrome in adults. Rabeprazole is used to treat ulcers (sores in the lining of the stomach or intestine) and is used in combination with other medications to eliminate H. pylori (a bacteria that causes ulcers) in adults. Rabeprazole is in a class of medications called proton-pump inhibitors. It works by decreasing the amount of acid made in the stomach.
