GLIOZ 20MG CAPSULE

About

Glioz 20mg Capsule contains Temozolomide, an oral alkylating agent used in the treatment of certain brain tumors. Temozolomide is a prodrug that is rapidly converted to its active metabolite, MTIC (5-(3-methyl-1-triazen-1-yl)imidazole-4-carboxamide), at physiological pH. MTIC exerts its cytotoxic effects by methylating DNA at various sites, primarily at the N7-guanine and O6-guanine positions. This methylation leads to DNA damage, triggering cell cycle arrest and ultimately apoptosis in rapidly dividing cancer cells.

This medication is a cornerstone in the management of newly diagnosed glioblastoma multiforme, often used in combination with radiation therapy, and for refractory anaplastic astrocytoma. Its ability to cross the blood-brain barrier is crucial for its efficacy in treating central nervous system malignancies. Due to its potent cytotoxic nature, careful monitoring of hematological parameters is essential throughout the treatment course to manage potential myelosuppression.

Uses

• Treatment of newly diagnosed glioblastoma multiforme.
• Management of refractory anaplastic astrocytoma.
• Adjuvant therapy following surgery and radiation for brain tumors.
• Used in specific protocols for certain neuro-oncological conditions.

Safety Measures

• Alcohol - Avoid alcohol as it may exacerbate nausea, vomiting, and fatigue, and could potentially interact with the medication's metabolism.
• Pregnancy - Temozolomide is teratogenic and can cause fetal harm. It is contraindicated in pregnancy. Effective contraception is required.
• Breastfeeding - Due to the potential for serious adverse reactions in breastfed infants, breastfeeding is contraindicated during treatment.
• Liver - Use with caution in patients with severe hepatic impairment. Liver function tests should be monitored regularly.
• Kidney - Use with caution in patients with severe renal impairment. Renal function should be monitored during treatment.
• Lung - Rare but serious pulmonary adverse reactions, including pneumonitis, have been reported. Monitor for new or worsening respiratory symptoms.
