Temozolomide

What is Temozolomide

Temozolomide is a prescription medicine used to treat certain types of brain tumors, including glioblastoma and anaplastic astrocytoma. It belongs to a class of drugs called alkylating agents. The medicine works by interfering with the DNA of cancer cells, preventing them from growing and dividing. Patients often experience improved treatment outcomes when this therapy is combined with radiation or other prescribed treatments.

Temozolomide used for

• Glioblastoma treatment — Temozolomide helps slow tumor growth and prolong survival in adults diagnosed with aggressive brain cancers.

• Anaplastic astrocytoma — The medicine improves response rates when used after radiation therapy.

• Adjunct therapy — Doctors may prescribe it alongside other treatments for better tumor control.

• Other brain tumors — Certain off-label uses may be recommended under strict medical supervision.

Chemical composition

Temozolomide capsules contain the active ingredient temozolomide, usually in strengths of 5 mg, 20 mg, 100 mg, 140 mg, 180 mg, or 250 mg per capsule. Each strength allows doctors to customize dosing according to patient needs.

Mechanism of action

Temozolomide works by attaching alkyl groups to DNA in cancer cells. This action damages the DNA, preventing cell replication and triggering cancer cell death. Healthy cells recover more efficiently, while tumor cells are selectively targeted. The medicine provides a systemic approach to managing brain tumors.

How it helps recovery

Regular use according to a doctor’s prescription can slow tumor progression and improve overall response to therapy. Patients may experience stabilization of disease and longer survival rates. Temozolomide supports other treatments, helping maximize the effectiveness of comprehensive cancer care.

Other benefits
