Brief summary

Groups 1, 3, 4, 5 and 6 of this research team adopted a single-center, open-label design. Group 2 used a three-sequence, three-period crossover design, where participants in this dose group were randomly assigned to the three sequences in a 1:1:1 ratio to undergo three-period crossover administration. Healthy adult subjects were selected to use TQC3302 inhalation spray to evaluate the safety, tolerability, and pharmacokinetic characteristics of single and multiple inhalations of TQC3302 inhalation spray in healthy participants.
