Brief Summary:
Introduction. Statins are generally well tolerated but not devoid of side effects. Quite often it is manifested by asymptomatic increase in the level of aspartate and alanine aminotransferase. In such cases patients to administer hepatoprotective drugs, but most of them used for this purpose are ineffective. The aim of this study was assess the usefulness of melatonin in counteracting the adverse hepatic events from statins. Methods. The research program included 60 patients(aged 47-65 years, 41 women and 23 men)with hyperlipidemia taking atorvastatin or rosuvastatin in dose 20-40 mg daily. The patients were randomly allocated in two groups. Group I (n=30) was recommended to take the same statin at a standardized daily dose of 20 mg together with melatonin at a dose 2 x 5 mg, at 7:00 and 21:00. In group II (n=30) patients took statins with placebo at the same time of the day. Follow-up laboratory tests (AST, ALT, GGT, ALP, cholesterol, triglycerides) were evaluated after 2,4 and 6 mounts of treatment.
