Did the doctor tell you that your cholesterol level is a little high? At such times, when it is difficult to lower cholesterol through diet alone, a special medicine that doctors prescribe is a combination of two drugs called Ezetimibe and Simvastatin. This is very popular in Sri Lanka under the brand name Vytorin. So today, let's talk about this medicine, how it works in our body, and the things we need to be careful about.
What exactly is this medicine? How does it work?
Simply put, this pill works in two ways to lower your cholesterol levels. Think of it like two security guards working together.
1. The part called Ezetimibe: This works by stopping the absorption of cholesterol from the food we eat into the body from the intestines. It's like closing a door.
2. Simvastatin: This belongs to a class of drugs called 'statins'. It works by reducing the production of cholesterol by our liver.
Because it works in both ways, this medication helps lower the level of bad cholesterol (LDL cholesterol) in the blood, reducing the risk of diseases such as heart disease and stroke. But remember, this is only given to people who cannot control their cholesterol with diet and exercise alone.
