Description
Description:
Keytruda is a medication manufactured by Merck Pharmaceuticals Ltd. containing the active ingredient Pembrolizumab. It is formulated as a 100 mg/4 mL injection.
Purpose and Indications:
Keytruda is a type of immunotherapy medication known as a programmed death receptor-1 (PD-1) blocking antibody. It is indicated for the treatment of various types of cancer, including:
- Melanoma: Keytruda is approved for the treatment of unresectable or metastatic melanoma, either as a single agent or in combination with other therapies.
- Non-Small Cell Lung Cancer (NSCLC): Keytruda is used in the treatment of advanced or metastatic non-small cell lung cancer (NSCLC) that has progressed despite prior chemotherapy.
- Head and Neck Squamous Cell Carcinoma (HNSCC): Keytruda is indicated for the treatment of recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) that has progressed on or after platinum-containing chemotherapy.
- Hodgkin Lymphoma: Keytruda is also approved for the treatment of classical Hodgkin lymphoma (cHL) in patients who have relapsed or progressed after autologous stem cell transplantation and post-transplantation brentuximab vedotin.
Mechanism of Action:
Pembrolizumab works by blocking the interaction between the PD-1 receptor on T cells and its ligands, PD-L1 and PD-L2, on tumor cells and other immune cells. By inhibiting this interaction, pembrolizumab helps to restore the ability of the immune system to recognize and attack cancer cells, leading to tumor regression and improved patient outcomes.
Administration:
Keytruda is administered as an intravenous infusion over a period of time determined by the healthcare provider. The dosage and frequency of administration depend on factors such as the type and stage of cancer being treated, the patient’s overall health, and their response to treatment.
Monitoring and Side Effects:
Patients receiving Keytruda should be monitored for potential side effects, which may include:
- Fatigue
- Nausea and vomiting
- Diarrhea
- Rash or itching
- Decreased appetite
- Muscle or joint pain
- Thyroid disorders (such as hypothyroidism or hyperthyroidism)
- Pneumonitis (inflammation of the lungs)
- Immune-mediated colitis
It is important for patients to report any unusual or severe side effects to their healthcare provider.
Prescription Requirement:
Keytruda is a prescription medication and should only be used under the guidance of a qualified healthcare professional. It is important to discuss with a doctor before starting pembrolizumab therapy, especially if there are underlying health conditions or concurrent medications.
Clinical Considerations:
Pembrolizumab represents a significant advancement in the treatment of cancer and has demonstrated durable responses and improved survival outcomes in many patients. However, treatment with Keytruda can also be associated with immune-related adverse events, which require careful monitoring and management.
Patient Education:
Patients receiving Keytruda should receive education about the purpose of the medication, proper administration techniques, potential side effects, and the importance of adherence to the prescribed treatment regimen. They should also be advised on strategies to manage side effects and maintain overall health during treatment, such as staying hydrated, eating a balanced diet, and getting regular exercise.
