Abstract

Simvastatin was investigated in an open multicenter study in 365 patients with primary hypercholesterolemia. After a four-week placebo phase the patients entered into the 12-week treatment phase. Simvastatin was administered in a daily dosage of 10 mg for 4 weeks. Depending on the lipid levels after 4 and 8 weeks of treatment, the dosage was to be maintained, or increased up to 40 mg/ day.

After 12 weeks of treatment a mean decrease in total cholesterol from 303.8 ± 54.5 mg/dl to 222.6 ± 42.1 mg/dl was observed, while LDL cholesterol decreased from 221.0 ± 54.8 mg/dl to 140.9 ± 40.6 and triglycerides decreased from 198.9 ± 133.1 mgldl to 164.7 ± 95.5 mg/dl. During the same time a mean increase in HDL cholesterol from 46.4 ± 15.2 mg/dl to 50.4 ± 15.5 mg/dl.

Adverse events were reported in 47 patients. Clinical adverse events were mainly gastrointestinal problems. Laboratory adverse events were most commonly slight increases of creatine phospho kinase (CPK) and of serum transaminases. The study was terminated prematurely by 17 patients. Clinical adverse events were responsible for two terminations and laboratory adverse events were the reason for the withdrawal of one patient.

Zusammenfassung

In einer offenen multizentrischen Studie wurde von 365 Patienten die Verträglichkeit und Wirksamkeit von Simvastatin untersucht. Nach einer vierwöchigen Diätphase und einer anschließenden vierwöchigen Plazebophase erhielten alle Patienten 12 Wochen lang abendlich Simvastatin.

Die Anfangsdosis betrug 10 mg. Nach jeweils vier Wochen wurde diese Dosis verdoppelt, sofern das Gesamtcholesterin weiterhin über 200 mg/dl lag. Die Simvastatindosis betrug bei 41% der Patienten nach acht Wochen 10 mg/Tag, bei 39% 20 mg/Tag und bei 20% 40 mg/Tag. Am Ende der Behandlungsphase war das Gesamtcholesterin im Mittel von 303,8 ± 54.5 mg/dl auf 222,6 ± 42,1 mg/dl, das Low density lipoprotein (LDL)-Cholesterin von 221,0 ± 54,8 mg/dl auf 140,9± 40,6 mg/dl, die Triglyzeride von 198,9± 133,1 mg/dl auf 164,7± 95,5 mg/dl abgesenkt und das High density lipoprotein (HDL)-Cholesterin von 46,4± 15,2 mg/dl auf 50,4 ± 15,5 mg/dl angehoben.

Simvastatin wurde gut vertragen. Unerwünschte Ereignisse wurden bei 47 Patienten berichtet. Klinische Ereignisse betrafen vorwiegend den Gastrointestinaltrakt. Laborereignisse waren vorwiegend leichte Creatinphosphokinasen(CPK)- und Transaminasenerhöhungen. 17 Patienten beendeten vorzeitig die Studie, bei drei Patienten wurde dies in Zusammenhang mit der Studienmedikation gesehen.
