General information about the trial
|
|||
Main objective of the trial |
To study the pharmacokinetic profile in plasma after naloxone administered intranasally in healthy volunteers.
Study the effect on sedation of oipioid after administration of the antidote naloxone
|
||
Protection of trial subjects |
The nasal spray was tested before the study to find out any pain or discomfort on administration. Any pharmacodynamic effects not expected because no opioid was administrated before the test drug.
|
||
Background therapy |
There was no background therapy or ongoing medication among the test subjects enrolled in this study | ||
