Folate analogues are drugs that mimic folic acid and are used in cancer treatment, inflammatory conditions, and ectopic pregnancies.

Folate analogues are a class of drugs that mimic the action of folic acid, a necessary nutrient for the formation of DNA, RNA, and various amino acids. These drugs work by interfering with the production of these essential cellular components, thus affecting cell growth and replication. Folate analogues are commonly used in the treatment of certain types of cancer, as well as various inflammatory and autoimmune conditions.


Folate analogues have a wide range of uses in the field of medicine. One of the most common applications is in the treatment of cancer, particularly certain solid tumors, leukemias, and lymphomas. These drugs are often used in combination with other chemotherapy agents to hinder the growth and spread of cancer cells. Additionally, folate analogues are employed in the management of chronic inflammatory and autoimmune conditions such as rheumatoid arthritis and psoriasis. By targeting rapidly dividing cells, these drugs help reduce inflammation and alleviate symptoms associated with these conditions. Furthermore, due to their ability to interfere with DNA synthesis, folate analogues have shown efficacy in treating ectopic pregnancies, where the fertilized egg implants outside the uterus. These drugs can halt the growth of the ectopic pregnancy, helping to prevent rupture and preserve the health of the mother.

It is important to note that this list is not exhaustive and there are other brands of folate analogues available.

Folate analogues, like any medication, carry the potential for side effects and interactions. Before starting treatment with these drugs, it is crucial to inform your healthcare provider about any existing medical conditions, allergies, or medications you may be taking.
