Manufacturer : AUREATE HEALTHCARE PVT LTDOrigin of Medicine : IndiaIntroduction:
GBMT 250mg Capsule consists of the active substance Temozolomide. It is prescribed to treat adults with brain cancer. It is the standard drug used in combination with radiotherapy to treat patients with glioblastoma multiforme and anaplastic astrocytoma. Glioblastoma and anaplastic astrocytoma are the most common and aggressive brain cancers with low chances of survival. Anaplastic astrocytoma is treated with GBMT 250mg Capsule or radiotherapy after biopsy, whereas Glioblastoma multiforme is treated with a combination of radiotherapy and GBMT 250mg Capsule, and then GBMT 250mg Capsule is continued as maintenance therapy.

- Treatment of refractory anaplastic astrocytoma in patients who experienced disease progression after being treated with nitrosurea and procarbazine.
How GBMT 250mg Capsule Works:
GBMT 250mg Capsule works by following a process called alkylation. After administration, GBMT 250mg Capsule gets converted into its active form called metabolite 5-(3-methyltriazen-1-yl) imidazole-4-carboxamide (MTIC). This metabolite reacts with water to form methyl diazonium ions. The methyl group from methyl diazonium ions transfer into the DNA and breaks the DNA strands that results in cell cycle arrest and cell death.
Interaction with other drugs:
Inform your doctor about any medications you are taking or have taken before the treatment.
