This terminated interventional trial (n=6) aimed to investigate the effects of low-dose ketamine on cardiovascular function.
This randomised, triple-masked, crossover Phase I study in six healthy adults assessed how low-dose ketamine affects sympathetic nervous system activity and cardiovascular function compared with saline placebo.
Primary outcome was the effect on muscle sympathetic nervous system activity and blood pressure; the crossover design allowed within-subject comparison between ketamine and isotonic saline.
Single low-dose ketamine administration in crossover design.
Ketalar (racemic ketamine); low dose not specified in registry text.
Isotonic/normal saline placebo comparator.
Normal saline placebo.
