Pemetrex Injection 500 mg/20 ml contains Pemetrexed, an antifolate chemotherapy agent used in the treatment of certain cancers. It interferes with folate-dependent enzymes required for DNA and RNA synthesis, thereby inhibiting cancer cell growth. This higher-strength formulation is used in oncology settings for appropriately dosed chemotherapy regimens.

Composition

• Active Ingredient: Pemetrexed

Mechanism of Action

Pemetrexed inhibits multiple folate-dependent enzymes involved in purine and pyrimidine synthesis. This disruption blocks the formation of DNA and RNA in rapidly dividing cells, leading to suppression of tumor growth and cancer cell death.

Indications

Pemetrex Injection is indicated for:

• Non-small cell lung cancer (NSCLC), particularly non-squamous type
• Malignant pleural mesothelioma
• Maintenance therapy in selected lung cancer patients
• Combination chemotherapy regimens as prescribed by an oncologist

Dosage and Administration

• Administered intravenously by qualified healthcare professionals only
• Dosage is based on body surface area and treatment protocol
• Used in cyclic chemotherapy schedules
