Abstract
The present invention relates to a microneedle patch system for continuously administering a large amount of drug to the skin. A microneedle patch provided by one aspect of the present invention may have increased drug content per unit area (1 cm2) to maximum of 100 mg unlike existing microneedles and thus has a higher drug content per unit area than an existing transdermal absorption agent, and is capable of delivering the drug into the body for a short time (within 24 hours) and a long time (approximately three days or more) via micropores formed by means of microneedles.
