Exclusion Criteria

• •Known metastatic disease of any type.
• •Known pulmonary infectious disease.
• •Pregnancy, nursing, or planning to become pregnant during the study or within one month after study drug administration.
• •Use of any of the following medications within the times specified before surgery:
• •1. Long-acting opioids within 3 days.
• •2. Any opioid medication within 24 hours.
• •Concurrent painful physical condition or concurrent surgery that may require analgesic treatment in the postoperative period for pain that is not strictly related to the surgical site being administered study drug (e.g., significant pain from other joints, chronic neuropathic pain, concurrent abdominal surgery, etc.), which have the potential to confound the postoperative study assessments.
• •Body weight less than 50 kilograms (110 pounds).
• •History of hypersensitivity or idiosyncratic reaction to amide-type local anesthetics, opioid medication, epinephrine, or sulfites.
• •Contraindication to epinephrine, such as concurrent administration of ergot-type drugs, monoamine oxidase (MAO) inhibitors or antidepressants of tryptoline or imipramine types, conditions where the production or exacerbation of tachycardia could prove fatal (e.g., poorly controlled thyrotoxicosis or severe heart disease), or any other pathological conditions that might be aggravated by the effects of epinephrine.
• •Administration of an investigational product within 30 days or 5 elimination half-lives of such investigational product, whichever is longer, prior to study drug administration, or planned administration of another investigational product or procedure during the subject's participation in this study.
• •History of, suspected, or known addiction to or abuse of illicit drug(s), prescription medicine(s), or alcohol within the past 2 years.
• •Uncontrolled anxiety, schizophrenia, or other psychiatric disorder that, in the opinion of the Investigator, may interfere with study assessments or compliance with the protocol.
• •Significant medical conditions or laboratory results that, in the opinion of the Investigator, indicate an increased vulnerability to study drugs and procedures, and expose the subject to an unreasonable risk as a result of participating in this clinical trial, such as: debilitating diseases, acute illnesses, hypotension, partial or complete conduction block, impaired cardiac function, untreated hypertension, advanced arteriosclerotic heart disease, cerebral vascular insufficiency, pre-existing abnormal neurological or neuromuscular disease (e.g., epilepsy, myasthenia gravis), advanced liver disease, sever renal impairment, advanced diabetes, co-morbid conditions associated with an immunocompromised status, such as blood dyscrasias, HIV/AIDS, or recent chemotherapy.
