Mechanism of Action

Etoposide is a derivative of podophyllotoxin that inhibits DNA synthesis resulting in the arrest of the cell cycle. At low doses, it inhibits cells from entering cell cycle and at high doses, cells entering mitosis are lysed. Absorption: Oral admin: 50% absorbed from the GI tract; plasma concentrations peak after 1 hr. Distribution: Rapid distribution but poor penetration of the blood-brain barrier. Protein-binding: 94%. Metabolism: Metabolised by CYP3A4. Excretion: Terminal half-life: 4-11 hr. Excreted in urine and faeces.

Special Precautions

Skin reactions may occur with accidental exposure; renal or hepatic disease. Periodic CBCs should be done before, during and after therapy. Increased risk of etoposide-toxicity in patients with low serum albumin. Acrylic material has been shown to crack and leak when used with undiluted etoposide inj.
