Abstract
A drug delivery device is provided. The drug delivery device includes a drug reservoir in fluid communication with a microneedle array. The drug delivery device has a sliding actuation mechanism that may be activated by a button or lever. Actuation of the drug delivery device inserts the microneedle array into the skin of a subject and causes a piston to compress the drug reservoir, thereby delivering the drug through the microneedle array to the subject.
