Arthroscopic irrigation solution and method for peripheral vasoconstriction and inhibition of pain and inflammation
A method and solution for perioperatively inhibiting a variety of pain and inflammation processes during arthroscopic procedures. The solution preferably includes a vasoconstrictor that exhibits alpha-adrenergic activity and one or more additional pain and inflammation inhibitory agents at dilute concentration in a physiologic carrier, such as saline or lactated Ringer's solution. The solution is applied by continuous irrigation of a wound during a surgical procedure for peripheral vasoconstriction and inhibition of pain and/or inflammation while avoiding undesirable side effects associated with systemic application of larger doses of the agents.
1. A composition for use in the inhibition of pain and inflammation at an anatomic site that is locally delivered to the anatomic site during an operative, therapeutic or diagnostic procedure, the composition comprising:
oxymetazoline;
a cyclooxygenase inhibitor; and
a pharmaceutical carrier, wherein the composition is locally delivered at the anatomic site and wherein oxymetazoline is included at a concentration of no greater than 300,000 nanomolar and the cyclooxygenase inhibitor is included at a concentration of no greater than 500,000 nanomolar.
2. The composition of claim 1 , wherein the cyclooxygenase inhibitor comprises ketoprofen.
3. The composition of claim 1 , further comprising amitriptyline.
4. The composition of claim 1 , wherein the pharmaceutical carrier comprises a liquid irrigation carrier.
5. A solution for inhibition of pain and inflammation at an anatomic site and adapted for local delivery to the anatomic site during an operative, therapeutic or diagnostic procedure, the solution comprising:
oxymetazoline and amitriptyline in a pharmaceutical carrier, wherein oxymetazoline is included at a concentration of no greater than 300,000 nanomolar, and amitriptyline is included at a concentration of no greater than 500,000 nanomolar.
6. The solution of claim 5 , wherein the solution further comprises an additional pain/inflammation inhibitory agent.
7. A solution for inhibition of pain and inflammation at an anatomic site and adapted for local delivery to the anatomic site during an operative, therapeutic or diagnostic procedure, the solution comprising:
at least one vasoconstrictive agent that is an α-adrenergic receptor agonist selected from the group consisting of oxymetazoline, p-aminoclonidine, naphazoline, tetrahydrozoline, anatazoline, tramazoline, monoxidine, apraclonidine, guanfacine, guanabenz and xylazine;
at least a first pain/inflammation inhibitory agent selected to act on a different molecular target than the α-adrenergic receptor agonist; and
a liquid carrier, wherein the α-adrenergic receptor agonist in the solution is delivered locally at a concentration of no greater than 300,000 nanomolar and the first pain/inflammation inhibitory agent in the solution is delivered locally at a concentration of no greater than 500,000 nanomolar, and wherein the solution is delivered locally at the anatomic site during the procedure.
8. A composition for use in the inhibition of pain and inflammation at an anatomic site that is locally delivered to the anatomic site during an operative, therapeutic or diagnostic procedure, the composition comprising:
oxymetazoline;
at least a first pain/inflammation inhibitory agent selected to act on a different molecular target than a α-adrenergic receptor, wherein the first pain/inflammation inhibitory agent is selected from the group consisting of cyclooxygenase inhibitors, serotonin receptor antagonists and histamine receptor antagonists; and
a pharmaceutical carrier, wherein the composition is locally delivered at the anatomic site and wherein oxymetazoline is included at a concentration of no greater than 300,000 nanomolar and the at least first pain/inflammation inhibitory agent is included at a concentration of no greater than 500,000 nanomolar.
9. A solution for inhibition of pain and inflammation at a joint of an extremity and adapted for local delivery to the joint during an operative, therapeutic or diagnostic procedure, the solution comprising:
oxymetazoline, amitriptyline and ketoprofen in a liquid carrier for local delivery to the joint.
