Brief Overview
Mekinist, with the generic name trametinib, is a medication used in cancer treatment, particularly for melanoma, non-small cell lung cancer (NSCLC), thyroid cancer, solid tumors, and low-grade glioma with BRAF mutations. It belongs to a class of medications called kinase inhibitors and works by blocking the action of an abnormal protein that signals cancer cells to multiply, thereby helping to stop the spread of cancer cells.
Role in Treating Cancer
Mekinist is often prescribed when the cancer has spread to other parts of the body, when surgery is not an option, or to prevent the cancer from returning after surgery. It is particularly effective in cancers with specific genetic markers, such as BRAF mutations, and is used alone or in combination with other medications like dabrafenib (Tafinlar) for enhanced effectiveness.
What is Mekinist?
Mekinist is used to treat various types of cancer, including melanoma, NSCLC, and thyroid cancer. It is also used for certain types of solid tumors in adults and children aged 6 years and older, and for a specific type of glioma in children aged 1 year and older. As a kinase inhibitor, Mekinist targets and blocks the action of proteins that contribute to the growth and spread of cancer cells.
Trametinib, the active ingredient in Mekinist, is a selective MEK inhibitor, specifically targeting MEK1 and MEK2, which are part of the MAPK pathway.is part of the multikinase inhibitors drug class. These drugs target multiple kinases, which are enzymes that play a key role in the growth and spread of cancer cells. By inhibiting these enzymes, Mekinist helps to slow down or stop the progression of cancer.
How it Works in the Body
Mekinist works by targeting specific kinases involved in the growth and spread of cancer cells. BlockingBy blocking these kinases, it prevents the cancer cells from multiplying and spreading, thereby helping to control the disease. Mekinist is particularly effective in cancers that have specific genetic mutations, making it a targeted therapy for these conditions.
