titleOfInvention |
Microneedle array with applied drug |
abstract |
The present invention provides a practical microneedle preparation by solving the problem that drug remains in the stratum corneum when actually applied as a percutaneous absorption preparation even though the drug can be quantitatively applied to the front end of the microneedle. A microneedle array having a needle length of 350 μm or more and 900 μm or less, a diameter of the apex of the tip of the needle is 20 μm or more and 100 μm or less, a drug application part, and a bioinsoluble polymer base. The lower end is a microneedle array that is 200 μm or more from the root of the needle. |
