Keytruda 100mg Injection

Keytruda 100mg Injection, with the active ingredient pembrolizumab, is an immunotherapy drug designed to bolster the body’s immune system in combating various cancers. It is approved for treating cancers such as melanoma, non-small cell lung cancer, classical Hodgkin lymphoma, urothelial carcinoma, gastric cancer, head and neck squamous cell carcinoma, cervical cancer, and primary mediastinal large B-cell lymphoma.

Mechanism of Action

Pembrolizumab functions by inhibiting the PD-1 protein on immune cells, thereby enhancing the immune system’s ability to detect and attack cancer cells. This mechanism can lead to durable responses and improved survival rates in certain patients with advanced cancers. However, individual responses can vary, and not all patients may experience these benefits.

Administration Guidelines

Administered intravenously by healthcare professionals, Keytruda 100mg Injection is typically given every three to four weeks. The specific dosage and treatment duration depend on the cancer type, its stage, and the patient’s overall health. During the infusion, patients are closely monitored for any adverse reactions.
