Usage
This combination medication is primarily prescribed for managing mixed dyslipidemia, hypercholesterolemia, and hyperhomocysteinemia, while also addressing deficiencies in folic acid, methylcobalamin (vitamin B12), vitamin B6 (pyridoxine), and vitamin D3 (cholecalciferol). It aims to lower total cholesterol, LDL cholesterol, and triglycerides, while increasing HDL cholesterol. This helps reduce the risk of cardiovascular events. The vitamins contribute to overall health, including nerve function, red blood cell formation, and bone health.
Pharmacological Classification: Antihyperlipidemic agent (statin) combined with vitamin supplements.
Mechanism of Action: Atorvastatin inhibits HMG-CoA reductase, an enzyme crucial for cholesterol synthesis. Folic acid, methylcobalamin, and vitamin B6 work together to lower homocysteine levels (a cardiovascular disease risk factor). Vitamin D3 promotes calcium absorption and bone health.
Alternate Names
This combination lacks a single international nonproprietary name (INN). It’s often referred to by its component drugs. Brand names vary regionally and include Lipifol-D3.
How It Works
Pharmacodynamics: Atorvastatin reduces cholesterol synthesis, leading to lower LDL and total cholesterol levels. The vitamins exert their respective effects on nerve function, red blood cell production, and bone health. Folic acid, Vitamin B6, and B12 lower homocysteine, thus reducing cardiovascular risk. Vitamin D supports bone health through calcium metabolism regulation and absorption.
Pharmacokinetics: Atorvastatin is absorbed orally, metabolized by the liver (primarily CYP3A4), and excreted in bile. Folic acid is absorbed in the small intestine, Vitamin B6 is readily absorbed and stored in the liver and muscle tissue, and Vitamin B12 absorption requires intrinsic factor and occurs in the ileum. Vitamin D is absorbed through the skin from sunlight and through dietary sources, then metabolized in the liver and kidneys into its active form. The exact pharmacokinetic interactions of this specific combination are not fully elucidated.
Mode of Action: Atorvastatin competitively inhibits HMG-CoA reductase. This reduces cholesterol biosynthesis in the liver, increasing LDL receptor expression. Enhanced LDL receptor expression increases the clearance of LDL cholesterol from the bloodstream. The vitamins act as coenzymes in various metabolic pathways.
Elimination Pathways: Atorvastatin is primarily eliminated via hepatic metabolism and biliary excretion. The other components, as described above, have different elimination pathways depending on their form and usage, mostly renal excretion.
