What Is FOLFIRI Chemotherapy?

FOLFIRI or a modified version is an abbreviation from the drugs given:

FOLinic Acid (Trade Name: Leucovorin)

Flurouracil (5-FU) (Trade Name:Adrucil, Efudex)

IRInecan Hydrochloride (Trade Name: Campto, Camptostar)

It is a two combination therapy as the Folinic acid is in the regimen to potentiate the effects of the 5-Flurouracil.

Irinecan hydrochloride is a topisimerase 1 inhibitor, a camptothecan analog derived from Camptotheca acuminata or ‘Happy Tree’.

Topisimerase 1 is an enzyme that handles the modelling of DNA, required to for cells to actively divide.

By blocking the enzyme, Irinecan prevents cancer cells from dividing and growing.

The Folinic acid and Irinecan is given as a drip or infusion over 90 minutes to 2 hours and the 5-FU is given as a bolus injection through your line.
