Focus Areas of Research

  • Evaluation of pharmacological mechanisms and effects in human models of experimental pain.
  • Evaluation of analgesic effect in experimental visceral pain models.
  • Investigation of biomarkers and surrogate end points in healthy volunteer studies to provide pivotal information on efficacy, dose-response and time-effects of drugs.

The Pharmacology Research Unit is an academically based experienced unit providing expertise and capacity for running experimental pain and pharmacological studies while offering a range of trial-related services. The Pharmacology Research Unit is a combination of a Clinical Research Organization and a Clinical Trial Unit and professionally offers all tasks related to drug trials. The mission of the Pharmacology team is to evaluate and reveal pharmacological mechanisms and effects in models of experimental pain. This is based on qualified selection of reproducible and validated models, assessment and evaluation methods, resulting in high quality drug trials. The first sponsor initiated study was performed in 2003 and therefore the team has great experience in performing such studies. With fully equipped laboratories, the unit can provide safe research with access to healthy volunteers and a variety of patient groups.
