Cisplatin is given intravenously in a clinical setting by healthcare professionals. The drug is usually administered slowly over several hours, typically in a hospital or chemotherapy clinic, under the supervision of an oncologist or a trained nurse.

Steps for Administration:

1. Pre-treatment: Patients are often pre-treated with fluids or other medications to help prevent some of the common side effects of Cisplatin, such as kidney toxicity or nausea.
2. Intravenous Infusion: Cisplatin is administered as an intravenous infusion over a period of several hours. The dosage and infusion time depend on the type of cancer being treated.
3. Monitoring: During administration, vital signs, kidney function, and blood counts are closely monitored.

Post-treatment Care: After administration, patients may be given fluids or diuretics to help flush the drug from the body and reduce the risk of kidney damage.

Cisplatin exerts its anticancer effects by forming covalent bonds with the DNA inside cells. Once Cisplatin enters a cell, it binds to the DNA, causing cross-links between the DNA strands. This cross-linking prevents the DNA strands from unwinding and replicating, a necessary step for cell division and cancer cell proliferation.

The inhibition of DNA replication triggers cell cycle arrest, particularly at the G1/S checkpoint. The damage to the DNA also activates cellular repair mechanisms, but because the damage caused by Cisplatin is overwhelming, these repair processes are unable to correct it, leading to cell death (apoptosis).

While Cisplatin targets cancer cells, it can also affect healthy cells, especially those that divide rapidly, such as those in the bone marrow, gastrointestinal tract, and hair follicles, leading to potential side effects.

Despite its effectiveness, Cisplatin can cause a range of side effects, some of which can be severe. These side effects are related to the drug’s action on both cancerous and healthy cells. Common and serious side effects include:

• Common Side Effects:
  • Nausea and vomiting: Often severe, especially within 24 hours of administration.
  • Fatigue: Many patients experience significant tiredness during treatment.
  • Hair loss: Hair loss is common but temporary.
  • Mouth sores: Patients may experience sores or ulcers in the mouth and throat.
  • Loss of appetite: A decrease in appetite is common during treatment.
• Serious Side Effects:
  • Kidney damage (nephrotoxicity): Cisplatin can cause significant kidney damage, especially if hydration is not managed properly.
  • Hearing loss (ototoxicity): Cisplatin can cause permanent hearing loss, especially with higher doses or prolonged use.
  • Peripheral neuropathy: Numbness, tingling, or pain in the hands and feet can occur due to nerve damage.
  • Bone marrow suppression: Cisplatin can suppress the production of blood cells in the bone marrow, leading to low white blood cell count (increased risk of infections), low red blood cell count (anemia), or low platelet count (risk of bleeding).

Cisplatin should be used with caution in certain patients. Key warnings and precautions include:

• Kidney Function: Cisplatin is nephrotoxic and can cause acute kidney injury, particularly in patients with pre-existing kidney conditions. Kidney function should be monitored closely before, during, and after treatment.
• Hearing Loss: Cisplatin can cause permanent hearing loss, especially with higher doses. Hearing tests may be conducted before, during, and after treatment.
• Pregnancy and Breastfeeding: Cisplatin is contraindicated during pregnancy due to its potential to cause harm to the fetus. It is also not recommended for breastfeeding, as it can be excreted in breast milk.
• Bone Marrow Suppression: Cisplatin can lead to bone marrow suppression, increasing the risk of infections, anemia, and bleeding. Blood counts should be monitored regularly.
• Hydration and Electrolyte Balance: Adequate hydration is crucial during Cisplatin treatment to reduce kidney toxicity. Electrolyte imbalances, such as low potassium or magnesium, may need to be corrected.

Cisplatin may interact with other medications, including:

• Nephrotoxic Drugs: Combining Cisplatin with other nephrotoxic drugs, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or certain antibiotics, may increase the risk of kidney damage.
• Ototoxic Drugs: Cisplatin has ototoxic (hearing-damaging) properties, and combining it with other ototoxic drugs like aminoglycoside antibiotics may increase the risk of hearing loss.
• Live Vaccines: Patients undergoing chemotherapy with Cisplatin should avoid live vaccines, as their immune system may be weakened during treatment.

Always inform your healthcare provider about all medications, including over-the-counter drugs and supplements, to avoid harmful interactions.

Cisplatin is administered in various doses depending on the type of cancer, the treatment protocol, and the patient’s condition. Here are general guidelines for dosage:

• Testicular Cancer: 20 mg/m² IV for 5 days as part of a combination regimen.
• Ovarian Cancer: 50-100 mg/m² IV every 3-4 weeks.
• Bladder Cancer: 70-100 mg/m² IV every 3-4 weeks.
• Lung Cancer: 75-100 mg/m² IV every 3-4 weeks.
• Head and Neck Cancer: 100 mg/m² IV every 3-4 weeks.
• Renal Adjustments: If renal impairment is present, doses should be reduced, and Cisplatin should be given with caution.

Cisplatin is a prescription-only chemotherapy agent and must be administered by trained healthcare professionals in a clinical setting, typically as part of a comprehensive cancer treatment regimen. Due to its potent toxicity and the need for careful monitoring, it is not suitable for home use.

Before starting Cisplatin, healthcare providers will conduct a thorough evaluation, including assessments of kidney function, hearing, and overall health. Regular monitoring during treatment is essential to detect and manage potential side effects promptly.
