title: Long-term maintenance of therapeutic response to lovastatin in patients with familial and non-familial hypercholesterolemia: a 3-year follow-up.
abstract: The 3-year efficacy of lovastatin alone or in combination with colestipol was evaluated in 54 patients with type 2 hyperlipoproteinemia (22 non-familial and 32 familial hypercholesterolemic patients). A sufficient and sustained reduction in LDL cholesterol was achieved in non-familial hypercholesterolemia with lovastatin alone (average dose 74 mg/day, range 40-80 mg/d), whereas combination therapy with lovastatin 80 mg/d and colestipol (average dose 11.9 g/d, range 5-20 g/d) was required in familial hypercholesterolemia. The percentage changes from baseline at 3 years in serum LDL cholesterol, HDL cholesterol and total triglycerides were in the lovastatin-only group -53%, +10% and -15%, respectively, and in the two-drug group -58%, +22% and -18%, respectively. A subgroup analysis in patients with non-familial hypercholesterolemia indicated that the lipid-modifying effects of lovastatin were similar in type 2A and 2B phenotypes, except for a greater triglyceride lowering effect in type 2B. The lovastatin-alone regimen was well tolerated, whereas addition of colestipol caused subjective side effects in many patients. Serious side effects or discontinuations due to therapies did not occur. Both therapies caused slight but significant increases (within normal limits) in average serum transaminase levels. After 36 months a significant rise of 1.7 kg in mean body weight was observed in the lovastatin-only group. The ophthalmological follow-up did not reveal any cataractogenic effect attributable to treatment during the 3.8-year follow-up period.
