Pemeta Injection 100 mg/4 ml contains Pemetrexed, a chemotherapeutic agent belonging to the class of antifolate antineoplastic drugs. It is used for the treatment of advanced malignancies, including non-small cell lung cancer (NSCLC) and malignant pleural mesothelioma. Pemetrexed works by interfering with the synthesis of nucleotides, which are essential for DNA and RNA production, thereby inhibiting cancer cell growth and proliferation.

This injectable formulation provides precise dosing and is intended for intravenous administration under strict medical supervision. Pemeta Injection is designed for use in hospital or clinical settings by trained healthcare professionals experienced in chemotherapy administration.

Mechanism of Action

Pemetrexed inhibits several key enzymes involved in folate-dependent metabolic pathways, including thymidylate synthase, dihydrofolate reductase, and glycinamide ribonucleotide formyltransferase. By blocking these enzymes, Pemetrexed disrupts nucleotide synthesis, leading to impaired DNA replication and RNA transcription in rapidly dividing cancer cells. This mechanism allows selective targeting of tumor cells while minimizing damage to normal tissues.

Indications

Pemeta Injection 100 mg/4 ml is indicated for:

• Non-small cell lung cancer (NSCLC): as a single agent or in combination with cisplatin for advanced or metastatic disease

• Malignant pleural mesothelioma: in combination with cisplatin for patients not suitable for surgery

• Other solid tumors: under investigational protocols or as determined by oncologists

Dosage and Administration

• Pemeta Injection should be administered intravenously by a healthcare professional.

• The recommended dose for NSCLC or mesothelioma is typically 500 mg/m² body surface area on day 1 of a 21-day cycle, administered as a 10-minute IV infusion.

• Patients are advised to receive premedication with folic acid, vitamin B12, and corticosteroids to reduce hematologic and gastrointestinal toxicities.

• Dosage adjustments may be necessary for renal impairment, liver dysfunction, or in the case of adverse reactions.

• Hydration and monitoring of renal function are essential during therapy.
