An Efficacy and Safety of Proprietary Formulations of Oral Ketamine + Aspirin in Treatment of Acute Headache

Headaches affect over 50% of patients annually, with close to 4% of ED visits for headache. Most headaches managed in the ED are benign, with 90% of these headaches classified as tension, migraine, or cluster. At present, the satisfaction with ED treatment of headache is low, and despite the multitude of available medications, the evidence- based treatment options are often quite limited. There are over twenty different types of medications available to the ED clinicians for managing headache, many with different routes of administration (parenteral, intranasal, subcutaneous, and oral). Many of these medications are provided in so-called "headache cocktail", which varies based on the physician, institution, and patient preferences.
