Interaction Details
Atorvastatin is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, breadfruit might inhibit cytochrome P450 3A4 (CYP3A4) and increase levels of drugs metabolized by these enzymes; until more is known, use with caution. In vitro, the breadfruit constituent artocarpin can inhibit CYP3A4 enzymes. Also, animal research shows that breadfruit leaf extract can weakly inhibit CYP3A4 enzymes. However, it is unclear if this inhibitory activity causes a clinically meaningful effect on the metabolism of CYP3A4 substrates.
Some drugs metabolized by CYP3A4 include amitriptyline (Elavil), amiodarone (Cordarone), citalopram (Celexa), felodipine (Plendil), lansoprazole (Prevacid), ondansetron (Zofran), prednisone (Deltasone), sertraline (Zoloft), and many others.

Interaction Details
Atorvastatin is classified as belonging to the following category: Glucuronidated Drugs
Breadfruit might increase the levels of drugs metabolized by uridine diphosphoglucuronosyl transferase (UGT). So far, this interaction has not been reported in humans. However, in vitro evidence shows that the breadfruit constituent artocarpin inhibits UGT. Theoretically, this could decrease the clearance and increase levels of glucuronidated drugs. Some drugs that are metabolized through glucuronide conjugation include acetaminophen (Tylenol, others) and oxazepam (Serax), haloperidol (Haldol), lamotrigine (Lamictal), morphine (MS Contin, Roxanol), zidovudine (AZT, Retrovir), and others.

Atorvastatin Overview
-
Atorvastatin 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. Atorvastatin 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. Atorvastatin 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). Atorvastatin 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 atorvastatin has been shown to prevent heart disease, angina (chest pain), strokes, and heart attacks.
