Serum levels of 7 alpha-hydroxycholesterol (7 alpha (OH)C) were found to increase considerably in hypercholesterolemic patients treated with cholestyramine. After 3-5 days, the normal level, which is in the range of 0.04 mg/l, rose to 1 mg/l. When the treatment was stopped it decreased rapidly with a half-life analogous to that of LDLs. This phenomenon was also observed in non-hypercholesterolemic humans. More than 75% of 7 alpha (OH)C is carried in blood by the LDLs.
