This is a Phase 1, open-label, repeat dose, ascending dose study assessing the PK, safety, tolerability, PD, and dose- or exposure-response of Topical Oxymetazoline for intra-anal application.~The primary objective of this study is to determine the plasma concentrations and PK parameters, as data allows, of oxymetazoline following single and repeated intra-anal application of oxymetazoline gel 1 mg, 5 mg or 10 mg in healthy male and female subjects.~The secondary objective of this study is to evaluate the safety and tolerability of repeated intra-anal application of oxymetazoline gel 1 mg, 5 mg or 10 mg in healthy male and female subjects.~A total of 32 healthy male and female subjects will be enrolled (16 subjects in the first cohort and 8 subjects in the remaining cohorts) and will be exposed to Topical Oxymetazoline 1 mg, 5 mg or 10 mg applied intra-anally QD for 11 consecutive days.
