4 Drug and Medication Information
4.1 Drug Indication

* Malignant pleural mesothelioma:

Pemetrexed Krka in combination with cisplatin is indicated for the treatment of chemotherapy nave patients with unresectable malignant pleural mesothelioma.

* Non-small cell lung cancer :

Pemetrexed Krka in combination with cisplatin is indicated for the first-line treatment of patients with locally advanced or metastatic non-small cell lung cancer other than predominantly squamous cell histology.

Pemetrexed Krka is indicated as monotherapy for the maintenance treatment of locally advanced or metastatic non-small cell lung cancer other than predominantly squamous cell histology in patients whose disease has not progressed immediately following platinum-based chemotherapy.

Pemetrexed Krka is indicated as monotherapy for the second-line treatment of patients with locally advanced or metastatic non-small cell lung cancer other than predominantly squamous cell histology.

5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Nucleic Acid Synthesis Inhibitors

Compounds that inhibit cell production of DNA or RNA. (See all compounds classified as Nucleic Acid Synthesis Inhibitors.)


Folic Acid Antagonists

Inhibitors of the enzyme, dihydrofolate reductase (TETRAHYDROFOLATE DEHYDROGENASE), which converts dihydrofolate (FH2) to tetrahydrofolate (FH4). They are frequently used in cancer chemotherapy. (From AMA, Drug Evaluations Annual, 1994, p2033) (See all compounds classified as Folic Acid Antagonists.)


Antineoplastic Agents

Substances that inhibit or prevent the proliferation of NEOPLASMS. (See all compounds classified as Antineoplastic Agents.)


Enzyme Inhibitors

Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction. (See all compounds classified as Enzyme Inhibitors.)
