Last Updated: 2025-02-17

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 12 participants
• Study Classification: INTERVENTIONAL

Brief Summary

This is a phase 1 randomized, double blind, crossover study examining the pharmacokinetic profile of two different doses of minoxidil sublingual tablets in healthy adult volunteers.

The main objective is to determine the pharmacokinetics of minoxidil following sublingual administration of a single dose in adult male and female healthy volunteers. The secondary objective is to evaluate the safety of minoxidil following sublingual administration of a single dose in adult male and female healthy volunteers.

A total of 12 participants (6 male and 6 female) will be recruited for study participation.

The duration of study participation is up to 43 days including screening and safety follow up. A single dose of study medication (strength A or strength B) will be administered on Day 1 to all study participants and PK samples will be taken periodically over a 12-hr period. After at least 7-day washout period the other dose of study medication (strength B or strength A, respectively) will be administered to all participants and PK samples will be taken periodically over a 12-hr period.
