摘要:
Particles of an organic acid salt of an amino acid amide or ester local anesthetic are employed as agents for the improved alleviation of pain. Particularly, the particles find use with surgically created wounds, where the particles may be administered directly into the bed of the wound or topically for transdermal transport.
