A nasal spray form of sumatriptan known as AVP-825 has been developed by Avanir and is generically available in some countries. Controversy
According to the American Headache Society, "Patients frequently state that they have difficulty accessing triptans prescribed to them." In the U.S. triptans cost from $12 to $120 each, and more that 80% of U.S. health  insurance plans limit place a limit on the amount of pills available to a patient per month, which has been called "arbitrary and unfair."

The Gothenburg criterion consists of the presence of peristaltic contractions, with an amplitude of 180 mm Hg at any place in the esophagus. The Richter criterion involves the presence of peristaltic contractions with an amplitude of greater than 180 mm Hg from an average of measurements taken 3 and 8 cm above the lower esophageal sphincter. It has been incorporated into a number of clinical guidelines for the evaluation of dysphagia. The Achem criteria are more stringent, and are an extension of the study of 93 patients used by Richter and Castell in the development of their criteria, and require amplitudes of greater than 199 mm Hg at 3 cm above the lower esophageal sphincter (LES), greater than 172 mm Hg at 8 cm above the LES, or greater than 102 mm Hg at 13 cm above the LES. Treatment
People are usually reassured that the disease is unlikely to worsen. However, the symptoms of chest pain and trouble swallowing may be severe enough to require treatment with medications, and rarely, surgery. The initial step of treatment focuses on reducing risk factors. While weight reduction may be useful in reducing symptoms, the role of acid suppression therapy to reduce esophageal reflux is still uncertain. Very cold and very hot beverages may trigger esophageal spasms. Medications
Medications for nutcracker esophagus includes the use of calcium-channel blockers, which relax the lower esophageal sphincter (LES) and palliate the dysphagia symptoms. Diltiazem, a calcium-channel blocker, has been used in randomized control studies with good effect.
