Interaction Details
Fexofenadine, Pseudoephedrine is classified as belonging to the following category: Organic Anion-Transporting Polypeptide Substrates (Oatp)
Theoretically, concomitant use of banaba with substrates of OATP might reduce the bioavailability of the OATP substrate.
In vitro research shows that banaba inhibits OATP, particularly OATP2B1. OATPs are expressed in the small intestine and liver and are responsible for the absorption of drugs and other compounds.

Banaba Overview
Banaba (Lagerstroemia speciosa) is a plant species in the family Lythraceae. It is native to tropical regions of Asia, including the Philippines, India, and Malaysia. It is commonly used as a natural remedy to lower blood sugar levels in people with diabetes, and has also been used to treat high blood pressure, obesity, and kidney problems. Banaba contains a number of active compounds, including corosolic acid, ellagitannins, and lagerstroemin, which are believed to be responsible for its medicinal effects. Dietary supplements are generally made from the leaf of the plant. Patented extracts of banaba, such as Glucosol (i.e., Glucofit), are often utilized in dietary supplements as well.
