Brief Summary

This is a Phase I trial to evaluate Pharmacokinetics, Pharmacodynamics and Safety of Isosorbide Mononitrate gel for usage in participants with anal fissure and healthy volunteers. Three doses will be used in patients with anal fissure (0.5%, 1.0% or 2.0%) and healthy volunteers will receive 2.0% dose. All treatment will last 7 days.
