Leucovorin: Drug Interaction

Risk Factor C (Monitor therapy)

Capecitabine

Leucovorin Calcium-Levoleucovorin may enhance the adverse/toxic effect of Capecitabine.

Floxuridine

Leucovorin Calcium-Levoleucovorin may enhance the adverse/toxic effect of Floxuridine.

Fluorouracil (Systemic)

Leucovorin Calcium-Levoleucovorin may enhance the adverse/toxic effect of Fluorouracil (Systemic). This effect is associated with the ability of leucovorin or levoleucovorin to enhance the anticancer effects of fluorouracil.

Fluorouracil (Topical)

Leucovorin Calcium-Levoleucovorin may enhance the adverse/toxic effect of Fluorouracil (Topical).

Fosphenytoin

Leucovorin Calcium-Levoleucovorin may decrease the serum concentration of Fosphenytoin.

PHENobarbital

Leucovorin Calcium-Levoleucovorin may decrease the serum concentration of PHENobarbital.

Phenytoin

Leucovorin Calcium-Levoleucovorin may decrease the serum concentration of Phenytoin.

Primidone

Leucovorin Calcium-Levoleucovorin may decrease the serum concentration of Primidone. Additionally, leucovorin/levoleucovorin may decrease concentrations of active metabolites of primidone (e.g., phenobarbital).

Tegafur

Leucovorin Calcium-Levoleucovorin may enhance the adverse/toxic effect of Tegafur. This effect is associated with the ability of leucovorin or levoleucovorin to enhance the anticancer effects of fluorouracil.

Risk Factor D (Consider therapy modification)

Glucarpidase

May decrease serum concentrations of the active metabolite(s) of Leucovorin Calcium-Levoleucovorin. Specifically, 6S-5-methyltetrahydrofolate concentrations may be reduced. Glucarpidase may decrease the serum concentration of Leucovorin CalciumLevoleucovorin. Management: Avoid leucovorin administration within 2 hours of glucarpidase dosing. Continue to administer the pre-glucarpidase leucovorin dose for at least the first 48 hours after glucarpidase administration, and dose based on methotrexate concentration thereafter.

Risk Factor X (Avoid combination)

Raltitrexed

Leucovorin Calcium-Levoleucovorin may diminish the therapeutic effect of Raltitrexed.

Trimethoprim

Leucovorin Calcium-Levoleucovorin may diminish the therapeutic effect of Trimethoprim. Management: Avoid concurrent use of leucovorin or levoleucovorin with trimethoprim (plus sulfamethoxazole) for Pneumocystis jirovecii pneumonia. If trimethoprim is used for another indication, monitor closely for reduced efficacy.

Monitoring Parameters:

Monitoring in patients on high-dose methotrexate therapy:

Monitor plasma methotrexate concentration. Leucovorin is continued until the plasma methotrexate level is less than 0.05 micromoles/L.


Monitoring in patients on Fluorouracil therapy:

  • Monitor CBC with differential and platelet counts
  • Liver function tests
  • Serum electrolytes.

Monitoring when methotrexate is used for tubal ectopic pregnancy:

  • Measure serum HCG on the days of methotrexate administration. When HCG levels decrease by more than 15%, continue monitoring weekly until non-pregnant levels are reached. If the HCG does not decrease after 4 doses, consider surgical management.
  • CBC with differential counts.
  • Liver function tests
  • Serum creatinine
  • Blood type and Rh.

How to administer Leucovorin?

  • Since leucovorin (or calcium folinate) contains calcium, the intravenous formulation should not be administered at a rate exceeding more than 160 mg/minute.
  • It can be administered orally, as an Intramuscular injection, Intravenous push, or Intravenous infusion over 15 minutes to 2 hours.

Leucovorin use in patients on Methotrexate:

  • Leucovorin should not be administered concurrently with methotrexate. To reduce the risk of toxicity associated with methotrexate without compromising the efficacy of methotrexate, leucovorin is commonly initiated one day after the start of methotrexate.
  • In case toxicity develops, it may be irreversible if leucovorin is not initiated within 40 hours after the start of methotrexate.

As a rescue after folate antagonists:

  • Administer Intravenously or as intramuscularly or orally. If the patient has nausea and vomiting, oral administration should be avoided. Oral administration
  • Do not administer orally in the presence of nausea or vomiting. Oral leucovorin at doses greater than 25 mg is not recommended.

Combination therapy with fluorouracil:

  • Fluorouracil is usually given after or at the midpoint of leucovorin infusion. It may be administered as an intravenous bolus injection or as an intravenous infusion over 10 -  120 minutes.

For the treatment of methanol toxicity:

  • Infuse leucovorin over 30 - 60 minutes.

Mechanism of action of Leucovorin:

  • Leucovorin calcium can be described as the activated or reduced form folic acid.
  • It displaces methotrexate intracellular binding sites and restores active folate stocks required for DNA and synthesis by competing against methotrexate.

It increases fluorouracil's activity stabilizes and stabilises the binding of 5-dUMP & thymidylate synthetase. Leucovorin lowers the riskHematologic toxicities of pyrimethamine(for the treatment of opportunistic infection). It is also useful in eliminating toxic metabolites of methanol, such as formic acid, from the body.Patients with methanol toxicities. Leucovorin provides a source of tetrahydrofolate, enhancing the action of 10-formyltetrahydrofolate dehydrogenase that converts methanol to carbon dioxide and water. [select-faq faq_id='7317'] It is well absorbed when administered orally or as an intramuscular injection. It is metabolized by the liver and the intestinal mucosa to the active form - 5-methyltetrahydrofolate (5MTHF). Bioavailability depends on the strength of oral tablets. Bioavailability is 97% at doses of 25 mg, 75% at doses of 50 mg, and 37% at doses of 100 mg. It has a Half-life elimination of about 4 - 8 hours The time to peak serum concentration is about 2 hours after oral ingestion, 10 minutes after intravenous administration, and 52 minutes after intramuscular administration.It is primarily excreted in the feces.
