  <brief_summary>
    <textblock>
      The study to be performed will utilize already FDA-approved marketed products in healthy&#xD;
      adults for the purpose to generate data for establishing rate of drug delivery of Transderm&#xD;
      Scop® TDDS (transdermal drug delivery system) in healthy adults and to ensure safety of&#xD;
      individuals utilizing these types of products.&#xD;

  </brief_summary>
  <detailed_description>
    <textblock>
      Transdermal drug delivery systems (TDDS) available in the form of patches are convenient,&#xD;
      attractive, and easy to use systems. Scopolamine patches are very popular TDDS available on&#xD;
      the United States market today. Accurate determination of the rate and extent of drug release&#xD;
      and absorption is crucial to ensure the safety of individuals using these and other types of&#xD;
      patches. Delivery rate can be determined early in the development process by using in vitro&#xD;
      skin flux permeation studies, and later in humans by accurately quantifying residual drug&#xD;
      from patches post-wear and in pharmacokinetic studies. In this proposal, the investigators&#xD;
      will employ two types of evaluation to determine the rate and extent of drug release and&#xD;
      absorption from RLD (reference listed drug) Transderm Scop® TDDS (transdermal drug delivery&#xD;
      system), namely residual drug analysis post-wear and pharmacokinetic analysis in healthy&#xD;
      adult volunteers. In addition, the investigators will compare the plasma drug concentrations&#xD;
      following patch and intravenous administration of Scopolamine, in order to determine the&#xD;
      absolute bioavailability of these patches. The investigators will conduct residual drug&#xD;
      analysis of TDDS following in vivo wear using highly sensitive validated quantification&#xD;
      methods. Positive outcomes of this project will identify appropriate methods to determine the&#xD;
      rate and extent of drug release and absorption from TDDS, and will help regulatory agencies&#xD;
      in the development of Guidances for Industry regarding the characterization of drug release&#xD;
      and absorption kinetics to ensure the safety of individuals utilizing these types of products&#xD;

The study to be performed will utilize already FDA-approved marketed products in healthy
      adults for the purpose to generate data for establishing rate of drug delivery of Transderm
      Scop® TDDS (transdermal drug delivery system) in healthy adults and to ensure safety of
      individuals utilizing these types of products.
Transdermal drug delivery systems (TDDS) available in the form of patches are convenient,
      attractive, and easy to use systems. Scopolamine patches are very popular TDDS available on
      the United States market today. Accurate determination of the rate and extent of drug release
      and absorption is crucial to ensure the safety of individuals using these and other types of
      patches. Delivery rate can be determined early in the development process by using in vitro
      skin flux permeation studies, and later in humans by accurately quantifying residual drug
      from patches post-wear and in pharmacokinetic studies. In this proposal, the investigators
      will employ two types of evaluation to determine the rate and extent of drug release and
      absorption from RLD (reference listed drug) Transderm Scop® TDDS (transdermal drug delivery
      system), namely residual drug analysis post-wear and pharmacokinetic analysis in healthy
      adult volunteers. In addition, the investigators will compare the plasma drug concentrations
      following patch and intravenous administration of Scopolamine, in order to determine the
      absolute bioavailability of these patches. The investigators will conduct residual drug
      analysis of TDDS following in vivo wear using highly sensitive validated quantification
      methods. Positive outcomes of this project will identify appropriate methods to determine the
      rate and extent of drug release and absorption from TDDS, and will help regulatory agencies
      in the development of Guidances for Industry regarding the characterization of drug release
      and absorption kinetics to ensure the safety of individuals utilizing these types of products

measure: Measurement of Time of Maximum Serum Scopolamine Concentration (Tmax)
time frame: Measured at time points: pre-dose, 1,2,3,4,5,6,8,10,12,24,36,48,60, and 72 hours during Intervention: Transderm Scop® and at time points: pre-dose, 2.5,5,10,20,30,45 minutes, 1.5,2,3,4,5,6,8,10,12 hours during Intervention: scopolamine HBr
measure: Determination of Area Under the Serum Concentration-time Curve (AUC)
time frame: Measured at time points:1,2,3,4,5,6,8,10,12,24,36,48,60,72,73,74,78,84,96,108,120 hours during Intervention: Transderm Scop® and at time points: 2.5,5,10,20,30,45 minutes, 1.5,2,3,4,5,6,8,10,12,24,36, and 48 hours during Intervention: scopolamine HBr
measure: Residual Drug Analysis in Worn TDDS
time frame: 3 - 6 months
description: This will be done in the TDDS after its removal to estimate total amount of absorbed scopolamine.
arm group label: Transderm Scop®
arm group type: Active Comparator
description: Each of the subjects will receive a single intravenous dose of 0.4 mg scopolamine hydrobromide and will wear the Transderm Scop® patch (1.5 mg) for 3 days in a crossover design with adequate washout in between. Subjects will be randomized to Group 1 (Transderm Scop® first followed by intravenous scopolamine hydrobromide) and remaining subjects will be randomized to Group 2 (intravenous scopolamine hydrobromide first followed by Transderm Scop®).
arm group label: Intravenous scopolamine hydrobromide
