omeprazole
Treatment for Cluster Headache
Omeprazole is a proton pump inhibitor (PPI) that suppresses gastric acid secretion by irreversibly blocking the H+/K+ ATPase enzyme in gastric parietal cells. In the context of cluster headache treatment, it may have a potential modulatory effect on neurogenic inflammation and neuronal sensitization, though its precise mechanism in headache management is not fully established.
