The present invention provides compositions, and methods for local administration of certain peptides or combination with certain small molecules that produce analgesia and anti-
inflammation in a
mammal. Exemplary polypeptides provide
peripheral analgesia and anti-
inflammation when administered via local topical, subcutaneous, intradermal, or intranasal administration, to provide analgesia and anti-
inflammation. Through
antagonism of
peripheral CGRP receptors alone, or in combination with inhibition of sensory
sodium channels or anti-inflammation, the compositions of the invention provide local therapeutic
pain relief with minimal undesired systemic side effects in a subject. Also provided are improved
peptide delivery techniques including microneedle unit
dose administering apparatus and methods. Also provided are hydrogel formulations for sustained local delivery to a subject of one or more of the compositions according to the invention in a therapeutically effective amount, thereby providing
local pain relief and / or reducing associated inflammation.
