Interaction Details

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

Theoretically, gymnema might increase or decrease levels of drugs metabolized by CYP2C9.
Animal research shows that gymnema can induce the CYP2C9 enzyme. In one animal study, gymnema caused a 2.4-fold increase in the clearance of tolbutamide, a CYP2C9 substrate, in rats. In vitro research also shows that gymnema can inhibit CYP2C9.

Gymnema Overview

Gymnema Gymnema (Gymnema sylvestre) is a plant species native to India and Africa that has been used traditionally in Ayurvedic medicine for centuries to treat a range of conditions, including diabetes, obesity, and digestive problems. Gymnema is thought to work by inhibiting the absorption of sugar in the intestines and by increasing the production of insulin in the pancreas. If applied topically to the tongue, it reduces the sweetness and bitter sensation of foods, which may deter excess sugar intake (the plant is sometimes referred to informally as 'the sugar destroyer'). One of the most popular natural medicines utilized for dietary supplements, an extract of the leaf (Gymnema leaf extract) is the most often standardized for use, although the root can be used as well.
