Safety and Tolerability Study of Transscleral Iontophoresis by the EyeGateÂ® II Drug Delivery Device System
The purpose of this study is to evaluate the safety and tolerability of a single iontophoretic dose of buffered solution administered through the EyeGate® II Drug Delivery System in healthy adult human volunteers.
This is a single center, randomized, single-masked, comparative group, safety and tolerability study of single dose levels of citrate buffer delivered through transcleral iontophoresis administered via the EyeGate® II Drug Delivery System. The current study will also determine the safety and tolerability of the dose ranges of transcleral iontophoresis from 2 mA through 7 mA and will determine the safety and tolerability of the application of the Eyegate II system on the eye for time ranges of up to 10.5 minutes.
Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Safety Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Treatment
EyeGate II® Drug Delivery System, Citrate buffer

Medical and Biotech [MESH] Definitions
Forms to which substances are incorporated to improve the delivery and the effectiveness of drugs. Drug carriers are used in drug-delivery systems such as the controlled-release technology to prolong in vivo drug actions, decrease drug metabolism, and reduce drug toxicity. Carriers are also used in designs to increase the effectiveness of drug delivery to the target sites of pharmacological actions. Liposomes, albumin microspheres, soluble synthetic polymers, DNA complexes, protein-drug conjugates, and carrier erythrocytes among others have been employed as biodegradable drug carriers.
Drug Delivery Systems
Systems for the delivery of drugs to target sites of pharmacological actions. Technologies employed include those concerning drug preparation, route of administration, site targeting, metabolism, and toxicity.
A chemical system that functions to control the levels of specific ions in solution. When the level of hydrogen ion in solution is controlled the system is called a pH buffer.
Artificial, single or multilaminar vesicles (made from lecithins or other lipids) that are used for the delivery of a variety of biological molecules or molecular complexes to cells, for example, drug delivery and gene transfer. They are also used to study membranes and membrane proteins.
Economic aspects of the fields of pharmacy and pharmacology as they apply to the development and study of medical economics in rational drug therapy and the impact of pharmaceuticals on the cost of medical care. Pharmaceutical economics also includes the economic considerations of the pharmaceutical care delivery system and in drug prescribing, particularly of cost-benefit values.
