Use of neuropeptides for ligament healing
Disclosed are a method and a corresponding pharmaceutical composition for treating damaged ligaments. Neurogenic compounds in general and neuropeptides in particular have been found to be highly effective in stimulated repair of ligaments damaged due to traumatic injury, ligament disease, and disuse. Preferred active ingredients for use in the method and corresponding pharmaceutical composition include calcitonin gene-related peptide (CGRP), cholecystokinin (CCK), dynorphin, enkephalin, galanin, neuropeptide Y (NPY), neurotensin, somatostatin, substance P (SP), thyrotropin-releasing hormone (TRH), vasoactive intestinal peptide (VIP).
1. A method of treating traumatic ligament injury in a subject in need thereof, the method comprising administering to the subject an amount of a neuropeptide selected from the group consisting of neuropeptide Y (NPY), substance P (SP), vasoactive intestinal peptide (VIP), and combinations thereof, the amount being effective to stimulate repair of the injured ligament.
2. The method of claim 1 , wherein the neuropeptide is administered in combination with a pharmaceutically suitable carrier.
3. The method according to any one of claim 1 or 2 , wherein the neuropeptide is administered to a mammal.
4. The method according to any one of claim 1 or 2 , wherein the neuropeptide is administered to a human.
5. A method of improving the strength of a damaged ligament, the method comprising administering to a subject having a damaged ligament a ligament strength-improving amount of a neuropeptide selected from the group consisting of neuropeptide Y (NPY), substance P (SP), vasoactive intestinal peptide (VIP), and combinations thereof.
6. The method according to claim 5 , wherein the neuropeptide is administered to a mammal.
7. The method according to claim 5 , wherein the neuropeptide is administered to a human.
