Lyfnua is used to treat chronic refractory or unexplained chronic cough in adults. It is specifically indicated for patients who do not respond to standard treatments or when the underlying cause of the cough is unknown.
How does gefapixant work?+
Gefapixant works by selectively antagonizing P2X3 receptors in sensory neurons. These receptors are involved in the cough reflex pathway. By blocking the binding of ATP to P2X3 receptors, gefapixant reduces the sensitivity of the cough reflex, thereby decreasing the frequency and intensity of coughing.
