What Is Binimetinib?
Put simply, Binimetinib is a type of medicine known as a targeted therapy. Unlike older chemotherapy medicines that affect many normal cells in your body, this medicine focuses on specific proteins inside cancer cells to stop them from growing.
Think of it like finding one specific troublemaker in a crowded room instead of stopping everyone around them. This medicine is mainly used to treat melanoma, a serious type of skin cancer.
In medical pharmacies, this medicine is often known by the brand name Mektovi. Remember that this is a very powerful, specialized medicine and is not like a common pain reliever you pick up at the store.
