Etoposide Injection

• Type: Chemotherapy medication

• Drug Class: Topoisomerase II inhibitor (plant-derived podophyllotoxin derivative)

• Form: Sterile solution or concentrate for intravenous (IV) infusion

How It Works

• Etoposide blocks the enzyme topoisomerase II, which is responsible for uncoiling and repairing DNA during cell division.

• This causes DNA strand breaks, leading to cell cycle arrest in the G2 phase and ultimately cancer cell death.

Common Uses

Etoposide injection is widely used in combination chemotherapy for:

• Small cell lung cancer (SCLC)

• Testicular cancer (in combination regimens like BEP: Bleomycin, Etoposide, Cisplatin)

• Lymphomas (Hodgkin’s and non-Hodgkin’s)

• Leukemias (some regimens for AML)

• Ovarian and other germ cell tumors

• Neuroblastoma, Wilms’ tumor (pediatric cancers, specialized protocols)

Advantages

• Effective in a variety of rapidly growing cancers

• Can be combined with cisplatin, bleomycin, or other drugs for synergistic effect

• Available in both oral and injectable forms, providing treatment flexibility

Possible Side Effects

Common:

• Low white blood cell counts (neutropenia) → infection risk

• Hair loss (alopecia)

• Nausea, vomiting

• Loss of appetite

• Mouth sores (mucositis)

Less Common but Serious:

• Severe bone marrow suppression

• Low platelet count (bleeding risk)

• Allergic reactions or infusion-related hypotension (requires slow infusion)

• Secondary leukemia (rare, risk increases with high cumulative doses)

Precautions

• Blood counts must be monitored before and during therapy

• Dose adjustment needed in kidney or liver impairment

• Administer via slow IV infusion to prevent low blood pressure

• Avoid live vaccines during treatment (immune suppression)

• Careful handling required (cytotoxic drug)
