Mechanism of Action
Temozolomide, the active ingredient in Temosure 100, is an alkylating agent that damages the DNA of cancer cells, preventing them from replicating and eventually leading to their death. It crosses the blood-brain barrier, making it particularly useful in treating brain tumors.
Indications
Temosure 100 Capsule is primarily prescribed for:
- Glioblastoma multiforme: A fast-growing brain tumor.
- Anaplastic astrocytoma: A less aggressive, but still malignant brain tumor.
Temozolomide is also occasionally used for other types of cancer, depending on the doctor’s assessment.
Dosage Guidelines
The dosage of Temosure 100 depends on several factors, including the patient’s body surface area (BSA), health condition, and the type of tumor being treated. The recommended dosing schedule typically follows one of these two regimens:
1. Standard Initial Therapy:
- For Newly Diagnosed Glioblastoma Multiforme (in combination with radiotherapy):
- Oral dose: 75 mg/m² once daily for 42 days (with a maximum of 49 days) concurrently with focal radiotherapy, followed by maintenance therapy.
- For Maintenance Therapy (following radiotherapy):
- The dose may vary:
- Cycle 1: 150 mg/m² once daily for 5 consecutive days, followed by a 23-day rest period.
- Cycle 2 and Beyond: The dose may be increased to 200 mg/m² once daily for 5 days, depending on the patient’s tolerance and blood counts.
- The dose may vary:
2. Recurrent Anaplastic Astrocytoma:
- Oral dose: 150-200 mg/m² once daily for 5 days in a 28-day treatment cycle.
Important Notes:
- Body Surface Area (BSA): Dosage is calculated based on BSA, so adjustments are made for each individual patient.
- Blood Count Monitoring: Regular blood tests are essential to monitor white blood cells, platelets, and other parameters, which help determine whether dose adjustments are needed.
