Soluble Fiber
Lovastatin
Soluble fiber is found primarily in fruit, beans, and oats, but it is also available separately as pectin, oat bran, and glucomannan. Two sources of soluble fiber—pectin (found in fruit) and oat bran (a component of oatmeal also available by itself)—have been reported to interact with lovastatin. The fiber from these two sources appears to bind the drug in the gastrointestinal tract and reduce absorption of the drug as a consequence. People taking this drug should avoid concentrated intake of soluble fiber, as taking lovastatin with a high soluble-fiber diet leads to reduced drug effectiveness.
