Clinical Mechanism — How the API Targets the HMG-CoA Reductase Enzyme
The Atorvastatin API is classified as a competitive inhibitor of the HMG-CoA reductase enzyme. This enzyme is the "rate-limiting" step in the liver's production of cholesterol, meaning it controls how fast the body makes its own fat.
How it Works in the Body: When a patient swallows a tablet made from Atorvastatin API, the substance travels to the liver. There, it mimics the natural substance the enzyme usually acts upon. Because the API binds to the enzyme much more strongly than the natural substance does, it effectively "plugs" the enzyme, preventing it from producing mevalonate—a precursor to cholesterol.
LDL Reduction: Because the liver can no longer make enough cholesterol, it starts "pulling" LDL (bad cholesterol) out of the bloodstream to compensate, significantly lowering the patient's blood levels.
Plaque Stabilization: Beyond just lowering numbers, the API has "pleiotropic effects," meaning it helps reduce inflammation in the blood vessels and strengthens the "caps" on…
