Background and Date of Approval
Meqsel 0.5mg Tablet has Trametinib as an active agent. It is a prescription medication used to treat certain types of cancers. Cancer is a disorder in which cells multiply uncontrolled and abnormally. This medication inhibits the cell growth and division of cancer cells and used to treat advanced melanoma. It is typically used with another drug (dabrafenib) to improve treatment outcomes. This drug used to treat skin cancer called melanoma which cannot be removed by surgery or has spread to other parts of the body. It also prevents melanoma from returning after being removed from surgery. Also used to treat a kind of lung cancer called non-small cell lung cancer (NSCLC).
Like all medications, it can cause side effects. The most common side effects include rash, diarrhea, nausea, vomiting, fatigue, and peripheral edema (hand and foot swelling). It is not recommended for adolescents and children under the age of 18 and for also who are allergic to it or one of its components. The recommended dose is one tablet daily, taken orally with or without food. Trametinib was approved by the U.S. Food and Drug Administration (FDA) in May 2013 for treating unresectable or metastatic melanoma.
Mechanism of Action of undefined
Trametinib is a medication called a mitogen-activated protein kinase (MAPK) kinase inhibitor. It inhibits the activity of the MEK enzyme, which is part of the MAPK pathway that is overactive in many cancer cells. In normal cells, the MAPK pathway plays an important role in regulating cell growth, differentiation, and survival. This pathway can become overactive and contribute to uncontrolled cell growth and tumour formation. It blocks the activity of the MEK enzyme, which is a key component of the MAPK pathway. Doing so helps slow down or stop the growth and spread of cancer cells with these specific genetic mutations. This can lead to a reduction in the size of tumours and an improvement in symptoms for patients with advanced or metastatic cancers.
Uses of undefined
- Unresectable or metastatic melanoma
- Non-small cell lung cancer in combination with Dabrafenib
- Advanced or metastatic thyroid cancer
- Metastatic solid tumours
undefined Drug administaration and Dosage available
Trametinib is typically administered orally as a tablet or capsule taken by mouth. The dose and frequency of it will depend on the specific type of cancer being treated and the patient's health status. For the treatment of melanoma, trametinib is usually taken once daily, either with or without food. It may be taken simultaneously as dabrafenib, another targeted therapy drug used in combination with trametinib for melanoma. In the management of non-small cell lung cancer, trametinib is usually taken once daily, at the same time as dabrafenib.
