— Explanation · 中文詳解 —
Atorvastatin 屬於 HMG-CoA 還原酶抑制劑（HMG-CoA reductase inhibitor），又稱「史他汀類（statins）」。其藥理機轉是透過抑制肝臟細胞內膽固醇合成的速率限制酶，進而降低血清中的總膽固醇、低密度脂蛋白（LDL）及三酸甘油酯。護理師需確保病人了解該藥物旨在控制血脂，而非用於糖尿病、高血壓或溶栓治療。
Atorvastatin is an HMG-CoA reductase inhibitor, also called a 'statin.' Its pharmacologic mechanism is inhibition of the rate-limiting enzyme of cholesterol synthesis in hepatocytes, thereby lowering total cholesterol, LDL, and triglycerides in serum. The nurse must ensure the client understands that this medication is intended to control blood lipids, not to treat diabetes, hypertension, or to dissolve thrombi.
