Interactions
Fluorouracil: Folinic acid may increase the toxicity associated with fluorouracil if the two are administered together. Some adverse effects that have occurred, particularly in elderly patients, include severe enterocolitis, diarrhea, and dehydration.
Sulfamethoxazole-trimethoprim: A potential drug interaction exists with concomitant use of sulfamethoxazole-trimethoprim and folinic acid. Folinic acid has been shown to decrease the efficacy of sulfamethoxazole-trimethoprim in the treatment of pneumocystis carinii, a common cause of pneumonia in AIDs patients
Side Effects
Side effects of Folinic Acid (Calcium folinate) :
Allergic sensitisation, rash, pruritus, eythema, urticaria, nausea, vomiting, pyrexia.
Mode of Action
Calcium folinate enters the cells as 5-methyl tetrahydrofolate and supplies the cofactor blocked by methotrexate. It stabilises the binding of 5-dUMP and thrymidylate synthetase, enhances flourouracil activity and neutralises the effects of folic acid antagonists such as methotrexate but increases those of 5-fluorouracil.
