How it works:
Pemetrexed is an antimetabolite that inhibits enzymes involved in the folate pathway essential for DNA and RNA synthesis in cancer cells. It halts tumour growth and proliferation. The drug shows high efficacy in combination with cisplatin and as maintenance therapy.
Recommended for:
Patients with non-small cell lung cancer (NSCLC)
Individuals with malignant pleural mesothelioma
Those receiving platinum-based chemotherapy
Patients requiring maintenance treatment post initial response
Treatment of malignant pleural mesothelioma in combination with cisplatin
First-line or subsequent treatment of locally advanced or metastatic NSCLC
Maintenance therapy in NSCLC after initial response
Second-line therapy in cases of disease progression post-chemotherapy
PEMNAT is administered intravenously under hospital supervision. It is given in chemotherapy cycles, typically every 21 days. Dosage is calculated based on body surface area and clinical evaluation. Patients often require folic acid, vitamin B12 and corticosteroids to reduce side effects.
