Interaction Details

Simvastatin 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.

Interaction Rating

Moderate

Likelihood of Occurrence

Possible

Interaction 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

Banaba Overview

Banaba 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.

Simvastatin Overview

  • Simvastatin is used together with diet, weight-loss, and exercise to reduce the risk of heart attack and stroke and to decrease the chance that heart surgery will be needed in people who have heart disease or who are at risk of developing heart disease. Simvastatin is also used to decrease the amount of fatty substances such as low-density lipoprotein (LDL) cholesterol (''bad cholesterol'') and triglycerides in the blood and to increase the amount of high-density lipoprotein (HDL) cholesterol (''good cholesterol'') in the blood. Simvastatin may also be used to decrease the amount of cholesterol and other fatty substances in the blood in children and teenagers 10 to 17 years of age who have familial heterozygous hypercholesterolemia (an inherited condition in which cholesterol cannot be removed from the body normally). Simvastatin is in a class of medications called HMG-CoA reductase inhibitors (statins). It works by slowing the production of cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body.

  • Accumulation of cholesterol and fats along the walls of your arteries (a process known as atherosclerosis) decreases blood flow and, therefore, the oxygen supply to your heart, brain, and other parts of your body. Lowering your blood level of cholesterol and fats with simvastatin has been shown to prevent heart disease, angina (chest pain), strokes, and heart attacks.
