Physiologically Based Pharmacokinetic Modelling of Intravenous and Intranasal Formulations of Naloxone in Healthy Volunteers.

Parc de Salut Mar·interventional·Posted Mar 12, 2024·Updated May 6, 2026

In Brief

A Phase 1 clinical trial evaluating Intravenous naloxone and Intranasal naloxone for Healthy. Completed, enrolled 8 participants across 2 sites.

Detailed Summary

This is a phase I interventional clinical trial and the aim will be to characterize the PK and PD of two formulations of naloxone (intranasal and intravenous) in healthy subjects, which will be used to verify/validate nasal-CNS-PBPK (Physiologically Based Pharmacokinetic) model predictions following intranasal dosing.
