Transdermal delivery technology that improves drug delivery system to increase drug
efficacy has recently become a key research and development field in the medical field.

The safest and most scientific system for delivering the
effects of pharmaceuticals and cosmetics to the skin

Transdermal Drug Delivery System (TDDS) Overview

A film-type patch contains a drug formulation designed to deliver the drug through the skin at a constant rate.
The drug is permeated at a constant rate to the skin. Therefore, it has the advantage of continuously maintaining the drug efficacy.
In addition, the Peak & Trough phenomenon does not appear in the blood concentration profile over time
of the use of the drug, so side effects are reduced while the effect is enhanced.

Blood Level	-Constant blood concentration -Increased therapeutic efficacy	-Savere flutation in blood concentration -Reduced therapeutic effect
Side Effect of the Drug	-Reduced adverse effects -Easy to remove when necessary	-Intial dreg burst -Gastrointestial disorder, hepatic effect, high blood pressure etc.
Medication Convenience	-Long lasting effect -Imporved patient compliance	-Frequent dosing -Taking promblem due to dyshagia
Marketablility	-High Price compared with generics -Securing monopolistic status	-High cost for NCE -HIghly competitive in generic market
