In this Phase I, proof of concept pilot study, we propose to study the safety and efficacy of transcutaneous neostigmine and glycopyrrolate facilitated by iontophoresis. The study design will consist of a screening visit to determine each individual's response to a previously established IV dose of NEO and GLY, followed by a dose titration study (two visits) of iontophoresed NEO and GLY. Study visits will be separated by no less than 2 days and no more than 14 days.
