This project examines experimental pain and chronic pain in the mouth, specifically the condition called atypical odontalgia (AO:atypical toothpain). In 16 patients with AO and 16 healthy persons, capsaicin (chili-pepper) is applied to the gingiva to cause pain. This pain is evaluated by the participants. In three sessions, 3 different medications are tested for effect on the pain. The medications are fentanyl, S-ketamine and placebo-treatment (saline). The aim is to know more about pain mechanisms in AO in order to develop an effective treatment.

Comparing patients receiving subanesthetic doses of Ketamine vs placebo to see if it can reduce narcotic needs for patients receiving a tonsillectomy and adenoidectomy
The efficient and secure techniques of anesthesia and sedation have always been needed for. One of these procedures is endoscopic retrograde cholangiopancreatography (ERCP), due to its painfulness and...
Ketamine, an antagonist of the N-methyl-D-aspartate receptor, has a rapid antidepressant effect, and its withdrawal may induce depression. However, the duration of depression and possibility of sponta...

A cyclohexanone derivative used for induction of anesthesia. Its mechanism of action is not well understood, but ketamine can block NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE) and may interact with sigma receptors.
A potent narcotic analgesic, abuse of which leads to habituation or addiction. It is primarily a mu-opioid agonist. Fentanyl is also used as an adjunct to general anesthetics, and as an anesthetic for induction and maintenance. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1078)
A hallucinogen formerly used as a veterinary anesthetic, and briefly as a general anesthetic for humans. Phencyclidine is similar to KETAMINE in structure and in many of its effects. Like ketamine, it can produce a dissociative state. It exerts its pharmacological action through inhibition of NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE). As a drug of abuse, it is known as PCP and Angel Dust.
A butyrophenone with general properties similar to those of HALOPERIDOL. It is used in conjunction with an opioid analgesic such as FENTANYL to maintain the patient in a calm state of neuroleptanalgesia with indifference to surroundings but still able to cooperate with the surgeon. It is also used as a premedicant, as an antiemetic, and for the control of agitation in acute psychoses. (From Martindale, The Extra Pharmacopoeia, 29th ed, p593)
A short-acting opioid anesthetic and analgesic derivative of FENTANYL. It produces an early peak analgesic effect and fast recovery of consciousness. Alfentanil is effective as an anesthetic during surgery, for supplementation of analgesia during surgical procedures, and as an analgesic for critically ill patients.
Pain is defined by the International Association for the Study of Pain as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage”. Some illnesses can be excruci...
