What class of drug is pemetrexed disodium?
Pemetrexed is in a class of medications called antifolate antineoplastic agents.
What is pemetrexed disodium used for?
Pemetrexed disodium is approved to be used alone or with other drugs to treat: Malignant pleural mesothelioma in patients who cannot be treated with surgery. Nonsquamous non-small cell lung cancer in certain patients whose disease is recurrent, locally advanced or has metastasized (spread to other parts of the body).
What enzyme does pemetrexed target?
Pemetrexed is a novel multitargeted antifolate that inhibits ≥ 3 enzymes involved in folate metabolism and purine and pyrimidine synthesis. These enzymes are thymidylate synthase, dihydrofolate reductase, and glycinamide ribonucleotide formyltransferase.
Is pemetrexed platinum-based?
A retrospective study has reported that platinum-based pemetrexed doublet leads to a significant improvement of disease control in comparison with platinum-based gemcitabine doublet in first-line setting for advanced NS-NSCLC patients.
What is pemetrexed and carboplatin?
Pemetrexed and carboplatin is a combination treatment used to treat mesothelioma and non-small cell lung cancer (NSCLC). It is best to read this information with our general information about chemotherapy and the type of cancer you have.
Is pemetrexed platinum based?
Why is folic acid needed with pemetrexed?
Dr. Bunn concluded that folic acid and vitamin B12 supplementation significantly reduces the number of episodes of grade 4 hematologic or grade 3-4 non-hematologic toxicity associated with pemetrexed disodium use. This may be attributed to decreases in homocysteine levels.
What is the mechanism of action of pemetrexed?
Mechanism of action By inhibiting the formation of precursor purine and pyrimidine nucleotides, pemetrexed prevents the formation of DNA and RNA, which are required for the growth and survival of both normal cells and cancer cells.
What is platinum pemetrexed?
Background/Aim: Pemetrexed plus platinum followed by pemetrexed maintenance has been one of the standard first-line treatments in advanced nonsquamous non-small cell lung cancer (NSCLC), but little is known regarding its safety and efficacy for patients with interstitial lung disease (ILD).
What is platinum chemotherapy?
Platinum-Based Drugs (Cisplatin, Carboplatin) These drugs form highly reactive platinum complexes that bind and crosslink DNA, a double-stranded molecule inside the nucleus of the cell that controls cellular activity. The chemical crosslinking within the DNA prevents cancer cells from growing and causes them to die.
What is pemetrexed injection?
Pemetrexed injection is used in combination with pembrolizumab and platinum cancer medicines to treat metastatic (cancer that has spread) non-squamous non-small cell lung cancer (NSCLC) with no EGFR or ALK gene mutations. It is also used together with cisplatin to treat advanced or metastatic, non-squamous NSCLC.
Can I take vitamin B12 during chemotherapy?
For supplements other than antioxidants: Use of vitamin B12 both before and during chemotherapy was associated with poorer disease-free survival and poorer overall survival. Use of iron during chemotherapy was associated with recurrence, as was use both before and during treatment.
How much folic acid is in pemetrexed?
The Food and Drug Administration’s patient package insert for pemetrexed (Alimta) reads as follows [1]: ‘You must start taking 350–1,000 mcg of folic acid every day for at least 5 days out of the 7 days before your first dose of Alimta’.
Is pemetrexed an immunotherapy?
The approval of pemetrexed and carboplatin with anti-PD-1 (pembrolizumab) for treatment of non-small cell lung cancer represents the first approved chemotherapy and immunotherapy combination.
Is Alimta platinum-based?
The FDA has expanded the indication for Alimta (pemetrexed) injection in combination with Keytruda (pembrolizumab) and platinum-based chemotherapy for the first-line treatment of patients with metastatic nonsquamous non–small cell lung cancer (NSCLC) without EGFR or ALK alterations.
Is it okay to have turmeric during chemotherapy?
Nutritional supplements and cancer treatment often don’t mix Turmeric is likely safe for most people, but it should be avoided during chemotherapy, radiation or blood-thinning therapies.
Why is folic acid and vitamin B12 given with pemetrexed?
SAN FRANCISCO—Adding vitamin B12 and folic acid to chemotherapy with pemetrexed disodium (Alimta) reduces the incidence of severe life-threatening toxicities, according to research presented at the 37th Annual Meeting of the American Society of Clinical Oncology (ASCO abstract 300).
Can you take B12 while on chemo?
What is pemetrexed disodium hydrate?

What is the molecular weight of pemetrexed?
Molecular Weight(MW): 471.37. Pemetrexed is a novel antifolate and antimetabolite for TS, DHFR and GARFT with K i of 1.3 nM, 7.2 nM and 65 nM in cell-free assays, respectively.
Does pemetrexed induce autophagy and apoptosis?
Pemetrexed induces autophagy and apoptosis. Pemetrexed Disodium Hydrate (LY-231514) is a novel antifolate and antimetabolite for TS, DHFR and GARFT with Ki of 1.3 nM, 7.2 nM and 65 nM, respectively. Pemetrexed Disodium Hydrate stimulates autophagy and apoptosis.
What is pemetrexed (ly231514) disodium?
Pemetrexed (LY231514) disodium is a novel classical antifolate, the antitumor activity of which may result from simultaneous and multipie inhibition of several key folate-requiring enzymes via its polyglutamated metabolites. Pemetrexed (LY231514) is one of the best substrates that is known for the enzyme FPGS (Km=1.6 μM and Vmax/Km=621).
