About Ketamine
What is Ketamine?
"Ketamine" is the term study registrants used on ClinicalTrials.gov. Registry labels are not always standard medical terms, and close variants of the same label appear as separate entries. In this snapshot the term appears on 11 chronic pain registry records worldwide.
How is Ketamine usually assessed?
Assessment of chronic pain generally involves a clinician taking a detailed history, a physical examination and, where relevant, tests to look for underlying causes. Pain rating scales and questionnaires about function, sleep and mood are often used. The approach depends on the person and the condition.
What kinds of treatments are studied for Ketamine?
Registered studies cover medicines, medical devices (such as nerve stimulators), procedures (such as nerve blocks or injections), physical and movement therapies, psychological approaches (such as cognitive behavioural therapy), education programs and digital tools. Being studied in a trial does not mean a treatment works or is approved. The interventions listed on this page come directly from the registry records.
