Anti-Dyslipidemic Drugs: Statins Overview

Study Notes

Anti-Dyslipidemic Drugs: Statins

Statins are drugs used to lower cholesterol levels.
They work by inhibiting the enzyme HMG-CoA reductase.
This reduces cholesterol production in the liver.
LDL receptors are upregulated, taking up cholesterol from the blood.
Statins maximize LDL cholesterol lowering.
Common statins include Atorvastatin, Rosuvastatin, Pravastatin, Simvastatin, Fluvastatin, and Cerivastatin.
Some statins (e.g., Atorvastatin, Rosuvastatin) can be taken at any time of the day, while others (e.g., Pravastatin) are best taken after meals.
Statins are primarily metabolized by CYP3A4, except Pravastatin.
Combining statins with CYP3A4 inhibitors can lead to increased toxicity.
Statin toxicity can manifest as myopathy (muscle damage), diabetes mellitus, and hepatotoxicity.
Monitoring creatinine phosphokinase (CPK) levels is important when starting statins to assess for muscle damage.
Food increases statin absorption, so they are often taken with meals except for some types.
Some drugs ending in "-statin," aren't HMG-CoA inhibitors, such as Cilastatin, Pentostatin, and Somatostatin, used with other medications.
Cilastatin is given with Imipenem to block its breakdown, Pentostatin inhibits adenosine deaminase, and Somatostatin is a hormone.

Pleiotropic Effects

Pleiotropic effects are additional benefits of statins beyond their cholesterol-lowering properties.
These effects often include plaque stabilization, improved endothelial function, reduced inflammation, less oxidative stress, and lower risk of thrombosis.
