At a glance
Temozolomide Hydrochloride is an anti-cancer drug used for glioblastoma multiforme, anaplastic astrocytoma, and metastatic melanoma. It inhibits cell division by alkylating DNA in cancer cells.
Indications
- Glioblastoma multiforme (adults) – with focal radiotherapy
- Anaplastic astrocytoma (recurrent or progressive)
- Metastatic melanoma
Pharmacology
Temozolomide is an inactive prodrug that hydrolyzes at physiological pH to the active metabolite MTIC. MTIC alkylates DNA at O6 and N7 positions of guanine, causing DNA cross-linking and strand breaks, which arrests the cell cycle and induces apoptosis in cancer cells.
Dosage
Adult Dose (Oral):
- Glioblastoma (concomitant): 75 mg/m²/day (42 days) + radiotherapy
- Glioblastoma (adjuvant): 150-200 mg/m²/day (5 days) – 23 days break (6 cycles)
- Recurrent/progressive glioma (chemotherapy-naive): 200 mg/m²/day (5 days) – 23 days break
- Recurrent/progressive glioma (prior chemo): 150 mg/m²/day (5 days) – 23 days break; increase to 200 mg/m² for cycle 2
- Metastatic melanoma: 200 mg/m²/day (5 days) – every 28 days
