However, it is important to note that temozolomide can cause side effects, including nausea, vomiting, fatigue, and low blood cell counts. These side effects can vary in severity and may require supportive care or dose adjustments.
Temozolomide Mechanism of Action
Temozolomide is an oral chemotherapy drug primarily used in the treatment of certain brain tumors, including glioblastoma multiforme (GBM). It belongs to the class of alkylating agents and works by damaging the DNA in rapidly dividing cancer cells, which inhibits their growth and ultimately leads to cell death.
Specifically, temozolomide methylates the DNA at specific sites, primarily on guanine bases. This methylation alters the structure of the DNA molecule, making it difficult for the cancer cells to repair the damage. As a result, the tumor cells accumulate DNA lesions, leading to their inability to replicate and survive.
Temozolomide’s mechanism of action is directly related to its ability to cross the blood-brain barrier, allowing it to effectively target brain tumors. Once inside the body, it is rapidly converted into an active form called MTIC (methyl-triazeno-imidazole-carboxamide). MTIC then breaks down further to generate a highly reactive compound called methyl diazonium ion, which is responsible for the DNA methylation process.
Combining temozolomide with other treatment modalities like radiation therapy has shown synergistic effects, enhancing the drug’s effectiveness in treating brain tumors. The use of temozolomide in combination with radiotherapy is often referred to as the Stupp protocol and has become a standard approach in the management of GBM.
It is important to note that temozolomide can have side effects, such as myelosuppression (reduced blood cell counts), nausea, vomiting, fatigue, and potential long-term effects on the bone marrow. Therefore, its administration requires careful monitoring and management by healthcare professionals.
