[Simvastatin in the treatment of familial hypercholesterolemia].
BACKGROUND
The association between hypercholesterolemia and premature atherosclerosis is almost universally accepted. Treatment of hyperlipoproteinemias represents a reasonable approach in preventive cardiology. The aim of the study was to prove a hypolipidemic effect of simvastatin, Zocor tablets à 10 mg, produced by MSD, U:S.A. in patients with familial hypercholesterolemia.


RESULTS
29 familial hypercholesterolemia heterozygotes have been treated with increasing dose of simvastatin (10 and 20 mg/day with the evening meal) for three months. All patients have been on AHA step I diet. The basic parameters of lipid and lipoprotein metabolism have been measured, as well the concentrations of apolipoproteins A-I and B, and the level of lipoprotein(a). Concentration of total cholesterol decreased after treatment with 10 and 20 mg of simvastatin by 20%, resp. 26%. The hypolipidemic effect was even more pronounced in LDL-cholesterol level, which was reduced by 24% respectively 34%. On the other hand therapy with simvastatin did not influence HDL-cholesterol at all. Also triglycerides concentration did not changed very significantly after administration of simvastatin (triglycerides levels were reduced by 7% respectively by 18%). Decline of LDL-cholesterol has been accompanied by decrease of apolipoprotein B concentration by 24%, resp. 26%. The concentration of lipoprotein (a) has not been statistically significantly influenced, even its level increased slightly. The body weight of the patients did not changed during the study. Simvastatin treatment has been well tolerated by the patients.


CONCLUSIONS
Simvastatin, Zocor, seems to be powerful hypolipidemic drug, which is to be used even in the treatment of familial hypercholesterolemia heterozygotes, who are usually very resistant to the therapy. The dose of 10 mg of simvastatin is usually sufficient to influence plasma lipids and lipoproteins. A double dose intensifies the hypolipidemic effect but this additional effect is not so expressive. Zocor is tolerated well by the patients and in safety laboratory we did not notice any important undesirable result.
