A Trial to Assess the Safety and Efficacy of Topical Salbutamol in Healthy Volunteers.

• Status: Completed
• Trial end date: 2019-07-01
• Target enrollment: 0
• Participant gender: All

Summary

This will be a single centre, double-blind, placebo (vehicle) controlled, randomised, dose escalation trial. Three concentrations of topical salbutamol gel will be compared, in a group-wise fashion, with a placebo administration at one incision site on each arm of the trial subjects. Each participant will be allocated to only one dosing group. The treatments will be paired anatomically so that for each pair of sites, one closed incision site will receive the active substance, while the other will receive placebo.
