Atromid S is a cholesterol-lowering medication that is widely used for managing elevated levels of triglycerides in the bloodstream. This drug contains cholestyramine, a compound that acts as a resin to absorb cholesterol and fatty acids from the digestive system. There are several synonyms for Atromid S, such as Lopid, Lipofib, Plavix, Crestor, and Zocor. These drugs are classified as statins, and they work by inhibiting the activity of an enzyme that is responsible for producing cholesterol in the liver. While these medications are highly effective in reducing cholesterol levels, they may also cause certain side effects, such as muscle pain, weakness, and liver damage. Therefore, it is essential to consult a healthcare specialist before taking any cholesterol-lowering drug.
