Will trametinib cause pimples during treatment?

Trametinib (Trametinib) is a drug used to treat certain cancers, particularly malignant melanomas with mutated BRAF genes. It belongs to a class of drugs called mitomycin kinase inhibitors (MEK inhibitors). Trametinib blocks intracellular signaling pathways by inhibiting the activity of MEK kinase, thereby inhibiting the growth and spread of cancer cells.

Some patients develop a rash, redness, or acne-like rash, which is more commonly known as pimples on the skin, during treatment with trametinib. This rash can become severe, leading to skin infection and hospitalization. The patient's skin may become very dry and if the skin cracks or bleeds, it is important to keep the skin clean to avoid infection. Although rash is one of the common side effects of trametinib, not every patient taking trametinib will develop rash. During the use of trametinib, if a rash or other skin reaction occurs, the patient should inform the doctor in time so that the doctor can make adjustments or provide appropriate treatment suggestions according to the situation.

The original drug of Trametinib has been launched in China and is included in the scope of medical insurance, but it may only be available to patients who meet the indications. The price of 2 mg*30 tablets is more than RMB 10,000. The original drug of Trametinib sold overseas, with the price of 2 mg*30 tablets, is more than RMB 7,000 (the price may fluctuate due to exchange rates). There are also generic trametinib drugs produced in other countries overseas, and their drug ingredients are basically the same as those of the original drugs sold domestically and abroad. For example, the price of a 2mg*30 tablet of a generic drug produced by a Laos pharmaceutical factory is more than 2,000 yuan (the price may fluctuate due to the exchange rate).
