Paclitaxel
is the active agent in ABRAXANE. It is a potent anticancer drug that stops cancer cells from growing and dividing by interfering with certain cell structures and killing the cancer cells. Paclitaxel can slow
tumor
growth or temporarily stop tumor growth altogether.
Solvent-based paclitaxel (Taxol® Injection) contains chemicals that are needed to dissolve the drug before it can be injected into the bloodstream. These solvents can cause side effects; therefore, patients usually need to take additional medications before they receive solvent-based paclitaxel to reduce the risk of getting these solvent-related side effects.
ABRAXANE offers a different approach for treating
metastatic breast cancer
with paclitaxel by using an
albumin
formulation to deliver the paclitaxel. Albumin is a human protein that carries nutrients throughout the body.
Because ABRAXANE does not contain solvents, there is a reduced risk of certain
hypersensitivity-related side effects,
so additional medications, such as steroids and antihistamines, are not necessary.
