Cisplatin

Introduction: What is Cisplatin?

Cisplatin is a chemotherapy medication primarily used to treat various types of cancer, including testicular, ovarian, bladder, and lung cancers. It belongs to a class of drugs known as platinum-based antineoplastic agents. Cisplatin works by interfering with the DNA in cancer cells, preventing them from dividing and growing. This medication is often part of a broader treatment regimen that may include other chemotherapy drugs or radiation therapy.

Uses of Cisplatin

Cisplatin is approved for several medical uses, including:

• Testicular Cancer: Often used in combination with other drugs to treat this type of cancer.
• Ovarian Cancer: Effective in treating advanced ovarian cancer, especially when combined with other agents.
• Bladder Cancer: Used for muscle-invasive bladder cancer and in combination with other treatments.
• Lung Cancer: Particularly non-small cell lung cancer, cisplatin is used in combination with other chemotherapy drugs.
• Head and Neck Cancers: Sometimes used in the treatment of cancers in these areas.

How It Works

Cisplatin works by forming crosslinks in the DNA of cancer cells. This means it binds to the DNA strands, preventing them from separating and replicating. As a result, the cancer cells cannot divide and grow, leading to cell death. In simpler terms, you can think of cisplatin as a "roadblock" that stops cancer cells from making copies of themselves, which is essential for their survival and growth.

Dosage and Administration

Cisplatin is typically administered by a healthcare professional. The standard dosage varies based on the type of cancer being treated, the patient's overall health, and other factors.

Adult Dosage:

For most cancers, the usual dose is 50-100 mg/m? given intravenously every 21 days.

Pediatric Dosage:

The dosage for children is often calculated based on body surface area and is usually similar to adult dosing.

Administration:

Cisplatin is given as an injection into a vein (intravenous infusion). It is not available in tablet form.

Side Effects of Cisplatin

Drug Interactions

Cisplatin can interact with several medications and substances, which may increase the risk of side effects or reduce its effectiveness. Major interactions include:

• Aminoglycoside antibiotics (e.g., gentamicin): Increased risk of kidney damage.
