Effect of Intranasal Oxytocin on Headache in Chronic Daily Headache
The Effect of Intranasal Oxytocin on Headache Intensity and Headache-associated Symptoms in Patients Suffering From Chronic Daily Headache
The objective of this prospective, randomized, double-blind, parallel-group, placebo-controlled study is to determine the effectiveness of intranasal oxytocin in subjects suffering from chronic daily headache. The primary outcome measure is the reduction in headache intensity after drug administration; secondary outcome measures are the headache symptoms, nausea, vomiting, photophobia, and phonophobia. Additional secondary outcome measures are intake of rescue medication and patient satisfaction over a period of 24 hours.
