Let's learn about Larotrectinib capsules, which target cancer cells and treat them.

It is normal for anyone to feel a little scared and anxious when they are diagnosed with cancer. But the most important thing you need to know is that as medical science continues to advance, there are now very effective, new treatments for cancer . Today we are going to talk about one such new, advanced treatment. The name of this drug is Larotrectinib. This is a targeted therapy that has been specially designed for certain types of cancer .

Simply put, what is Larotrectinib?

Think of cancer cells as a type of weed that spreads out of control. There is a special 'switch' that helps these weeds grow and spread. This 'switch' is what we call a protein in medicine. This drug called Larotrectinib does a very smart thing. It goes straight to the 'switch' that helps the cancer cells grow, that is, that special protein. It turns it off. Then the cancer cells lose or greatly reduce their ability to divide, grow, and spread to other parts of the body.

This is not like regular cancer drugs. Regular drugs can sometimes damage healthy cells in the body. But this kind of targeted therapy mainly damages only cancer cells. Therefore, the side effects can be relatively reduced. This drug can be found in the market under the brand name VITRAKVI .
