A new drug for cholesterol? Let's learn about Repatha (Evolocumab) in simple terms!
Table of Contents ▾

When we hear the word 'cholesterol', most of us cringe a little, don't we? Especially when the doctor says, "Your bad cholesterol, that is, LDL level, is a little high," we get a little scared. What we eat and drink, whether we exercise or not, and sometimes genetic factors also affect this. So, almost all of us have heard of 'statin' type pills that are given to control cholesterol. But for some people, these drugs alone are not enough, or they cannot be used. Today we are talking about a slightly advanced, new type of drug that is used in such cases. That is Repatha.

What is Repatha? How does it lower cholesterol?

Simply put, Repatha is a shot that lowers the "bad" cholesterol, or LDL (Low-Density Lipoprotein) cholesterol levels in our bodies. This is not a pill that we usually take, but an injection that is injected under the skin.

Now look at how this works. Imagine that our liver is the filter that removes bad cholesterol from the blood. But our body also has a protein called PCSK9 (Proprotein Convertase Subtilisin Kexin type 9) . This is like someone who reduces the efficiency of that filter, interferes with it. When the PCSK9 protein increases, the liver's ability to remove LDL from the blood decreases.

What Repatha does is inhibit the activity of that 'messing up' PCSK9 protein . When it is stopped, the liver's filter can work at maximum efficiency again without any interference, capturing and actively removing the bad cholesterol (LDL) in the blood. Do you understand? This means that this medicine helps our body's own natural process that controls cholesterol.

This is not a medicine for everyone. A doctor will only recommend it in a few specific cases.

  • For adults with existing heart disease: This medication is used to reduce the risk of heart attack, stroke, or other heart disease. It is usually given with other cholesterol medications, such as statins.
  • For people with genetically inherited high cholesterol: Some people have very high cholesterol levels due to genetic conditions that are passed down from generation to generation. These conditions are called Heterozygous Familial Hypercholesterolemia (HeFH) and Homozygous Familial Hypercholesterolemia (HoFH) . Repatha is recommended for adults and children over 10 years of age with these conditions to control LDL levels.

Most importantly, it is essential to follow a healthy diet and exercise while using this medication. Repatha is not magic, it is just one part of the treatment plan.

What are the benefits and effects of this medicine?

Clinical studies of Repatha have shown promising results. These studies compared Repatha with a placebo (a dummy treatment) and with other cholesterol medications, such as statins.

Let's explain this further with the table below.
