Registration Number
NCT01744964
Lead Sponsor
Rambam Health Care Campus
Brief Summary

The aims of this study were to assess the effects of the dopamine agonist apomorphine on experimental pain models in healthy subjects and to explore the possible association between these effects and a common polymorphism within the dopamine transporter gene.

Detailed Description

Healthy volunteers (n=105) participated in this randomized double-blind, placebo-controlled, cross-over trial. Heat pain threshold and intensity, cold pain threshold, and the response to tonic cold pain (latency, intensity, and tolerance) were evaluated before and for up to 120 min after the administration of 1.5 mg apomorphine/placebo. A polymorphism (DAT-1) within the dopamine transporter gene (SLC6A3) was investigated.
