neurokinin-1 receptor antagonists

Neurokinin-1 receptor antagonists are medications that block a specific protein called neurokinin-1 (NK1) receptors in the brain and body. These receptors bind to a substance called substance P, which plays a role in processes like nausea and vomiting. By blocking NK1 receptors, these drugs help prevent and reduce nausea and vomiting, especially in patients undergoing cancer treatments like chemotherapy. They are often used alongside other anti-nausea medications to improve comfort and recovery during treatments.
