Renal Dose
Renal impairment:
CrCl (ml/min) Dosage Recommendation
<45 Usage is not recommended.
Administration
IV Preparation
Aseptically reconstitute with 20 mL of 0.9% NaCl (preservative free) to give a 25 mg/mL solution
Gently swirl until completely dissolved; resulting solution is clear and ranges in color from colorless to yellow/green-yellow without adversely affecting quality
Aseptically dilute required dose to 100 mL with 0.9% NaCl (preservative free)
IV Administration
Infuse over 10 min
Contra Indications
Hypersensitivity.
Precautions
Monitor CBC, platelet counts, and CrCl for nadir and recovery before each cycle. Periodic hepatic monitoring Premedication with folate and vitamin B12 are recommended as prophylaxis against haematological and GI toxicity during treatment. Pre-treatment with a corticosteroid also reduces the incidence and severity of skin reactions. Caution when used in renal or hepatic impairment. Not recommended for use in pregnancy.
Lactation: not safe
Pregnancy-Lactation
Pregnancy
Based on findings from animal studies and its mechanism of action, therapy can cause fetal harm when administered to a pregnant woman; there are no available data in pregnant women; in animal reproduction studies, intravenous administration of pemetrexed to pregnant mice during organogenesis was teratogenic, resulting in developmental delays and malformations at doses lower than recommended human dose of 500 mg/m²; advise pregnant women of the potential risk to a fetus
Contraception
Therapy can cause fetal harm when administered to a pregnant woman; because of potential for genotoxicity, advise females of reproductive potential to use effective contraception during treatment for at least 6 months after final dose
Advise males with female partners of reproductive potential to use effective contraception during treatment and for 3 months after final dose
Infertility
Therapy may impair fertility in males of reproductive potential; it is not known whether these effects on fertility are reversible
Lactation
There is no information regarding presence of drug or its metabolites in human milk, effects on breastfed infant, or on milk production; because of potential for serious adverse reactions in breastfed infants, advise women not to breastfeed during treatment and for 1 week after last dose
Interactions
High doses of NSAIDs and aspirin may reduce the elimination of pemetrexed; avoid usage 2 days (5 days for longer-acting NSAIDs) before, during and 2 days after treatment with pemetrexed in patients with impaired renal function. Additive GI side effects when used with SSRIs, acetylcholinesterase inhibitors, aripiprazole or ziprasidone. Additive sedation when used with psychotropics. Concurrent use with nephrotoxic drugs (e.g. aminoglycosides, loop diuretics, platinum compounds and ciclosporin) may decrease pemetrexed clearance, thus increasing the risk of toxicity. Clearance may be reduced when used with drugs that are cleared by tubular secretion e.g. probenecid and penicillin.

Mechanism of Action
Pemetrexed is a thymidylate synthase inhibitor. It works by inhibiting thymidylate synthase, dihydrofolate reductase, glycinamide ribonucleotide formyltransferase and aminoimidazole carboxamide ribonucleotide formyltransferase, the enzymes involved in folate metabolism and DNA synthesis, thus inhibiting purine and thymidine nucleotide and protein synthesis.
