Why the study?
Evidence suggests functional sympatholysis is endothelial-dependent but nitric oxide- and prostaglandin-independent, leaving its underlying pathways unclear.
Does cytochrome P450-2C9 inhibition attenuate functional sympatholysis in healthy young adults?

CYP450 pathways contribute to functional sympatholysis in young healthy humans.
CYP450-2C9 contributes to functional sympatholysis; extends endothelial mechanisms beyond NO/prostaglandins and warrants targeted studies in cardiovascular disease.
Evidence suggests that functional sympatholysis is an endothelial-dependent, nitric oxide and prostaglandin-independent process. We found that cytochrome P450-2C9 (CYP450-2C9) inhibition attenuated sympatholytic responses during dynamic handgrip exercise with superimposed lower body negative pressure. These data indicate that CYP450 pathways contribute to functional sympatholysis in young healthy humans.
