A
medical device, comprising: an array of microneedles, and a
coating disposed on the microneedles, wherein the
coating comprises: a
local anesthetic selected from the group consisting of
lidocaine,
prilocaine, and a combination thereof; and a
local anesthetic dose-extending component selected from the group consisting of alpha 1
adrenergic agonists, alpha 2
adrenergic agonists, and a combination thereof; wherein the
local anesthetic is present in an amount of at least 1 wt-% based upon total weight of solids in the
coating, and wherein the
dose-extending component / local
anesthetic weight ratio is at least 0.0001; a
medical device, comprising an array of dissolvable microneedles, the microneedles comprising: a dissolvable matrix material; at least 1 wt-% of a local
anesthetic selected from the group consisting of
lidocaine,
prilocaine, and a combination thereof; and a local
anesthetic dose-extending component selected from the group consisting of alpha 1
adrenergic agonists, alpha 2 adrenergic agonists, and a combination thereof; wherein the dose-extending component / local anesthetic weight ratio is at least 0.0001, and wherein wt-% is based upon total weight of solids in all portions of the dissolvable microneedles which contain the local anesthetic; a method of extending a topically delivered local anesthetic dose in
mammalian tissue using the devices; and methods of making the devices are provided.
