Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The aim of the study is to use the NK1 receptor antagonist aprepitant as a pharmacological tool to determine the physiological role of the regulation of adrenocortical secretions by the sympathetic system via SP. The influence of the compound on plasma aldosterone and cortisol concentrations will be evaluated in basal conditions and after stimulation. This pilot “proof-of-concept" study will allow us verifying that corticosteroid secretions are actually controlled in vivo by a neural stimulatory tone via SP ;Secondary Objective: To determine the physiological conditions that involve the regulation of corticosteroid production by tachykinins.;Primary end point(s): Plasma aldosterone levels during orthostatic test;Timepoint(s) of evaluation of this end point: Day 4 of treatment | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Basal aldosterone alteration, aldosterone variation during metoclopramide and hypoglycaemia tests. Basal and stimulated alterations of renin, cortisol and ACTH during 3 different stimulatory tests (upright, metoclopramide and hypoglycaemia tests) ;Timepoint(s) of evaluation of this end point: Day 4, day 5 and day 7 of treatment | — |
