Interaction Details
Fluvastatin is classified as belonging to the following category: Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, black seed might increase levels of drugs metabolized by CYP2C9.
In vitro research suggests that thymoquinone, a constituent of black seed, can decrease the metabolism of phenytoin by a mechanism possibly related to the inhibition of CYP2C9. The effect of black seed on CYP2C9 is unclear. This has not been shown in humans.

Black Seed Overview
Black seed, also known as black cumin, is a flowering plant belonging to the Ranunculaceae family. It is used in traditional medicine for the treatment of several conditions, including bronchitis, colic, fatigue, fever, headache, toothache, back pain, and infections. Most dietary supplements containing black seed market it as supporting the respiratory and digestive system, as well as improving immune health. Black seed oil is obtained from the seeds being cold-pressed.
In regard to supplements, whole black seeds contain both the oil and other components such as fiber and proteins, while black seed oil is a concentrated source of the oil only. Both can be taken as supplements, but black seed oil contains larger amounts of active components, while whole seeds can provide additional nutrients and fiber.
Fluvastatin Overview
-
Fluvastatin 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. Fluvastatin 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. Fluvastatin 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). Fluvastatin 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 fluvastatin has been shown to prevent heart disease, angina (chest pain), strokes, and heart attacks.
