Cladribine is an antineoplastic drug of the purine group and it is an antimetabolite. It is recommended in the treatment of hairy cell leukemia, which is a type of blood cancer caused by overproduction of B lymphocytes (type of white blood cells). The term "hairy cell" refers to protuberances on the surface of lymphocytes that are similar to hair.

What is Cladribine?

Cladribine is a cytotoxic agent (capable to damage cells and eventually cause their death), analogue of the purines, which are one of the fundamental chemicals in the structure of the DNA. Once inside the body, more precisely in the lymphocytes, Cladribine is converted in a chemical substance able to intervene in the production of new DNA, to prevent cell division and to slow down the progression of leukemia.

How should Cladribine be taken?

Cladribine is administered via intravenous infusion.
