The present invention relates to a composition for preparing a microneedle, a soluble microneedle, and a microneedle percutaneous patch comprising the soluble microneedle. A soluble microneedle contained in a microneedle percutaneous patch of the present invention has a high drug loading capacity and excellent strength and thus may contain an effective amount of donepezil or a pharmaceutically acceptable salt thereof even with a small area of the microneedle. Accordingly, the present invention is economical and produces a lower level of skin irritation.
