Outcome Measures
Primary Outcomes (1)
Single and multiple dose Pharmacokinetic parameters
Single- and multiple-dose PK parameters for topical DTZ and single-dose PK parameters for oral DTZ including AUC(0-t), AUC(0-∞), Cmax, tmax, t1/2 and CL/F. PK parameters for DTZ, and its two metabolites (N-desmethylditiazem and O-desacetyldiltiazem) will be presented in Data Listings and summarized by Day (Study Day 1, 7 and 14). Descriptive statistics will include n, mean, SD, %CV, geometric mean,median, minimum, and maximum.
up to 6 months after enrollment begins
Secondary Outcomes (1)
Safety as determined by nature, severity and relationship of adverse events, clinical labs, physical exam findings, vital signs and Electrocardiogram
Up to 6 months after enrollment begins
Study Arms (1)
Diltiazem Hydrochloride
EXPERIMENTALTopical cream and oral pill
