Detailed Description:

Diagnosis and Main Criteria for Inclusion:

Healthy adult patients (18 to 76 years old), who scored PS-1 to PS-3 according to the American Society of Anesthesiologists Physical Status Classification System, requiring primary, unilateral, first metatarsal bunionectomy surgery alone or with ipsilateral hammertoe repair without additional collateral procedures.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Requires primary unilateral first metatarsal bunionectomy surgery alone or with ipsilateral hammertoe repair under regional anesthesia. The patient requires collateral orthopedic surgical procedures other than ipsilateral hammertoe repair may not be enrolled into the study.
  • 18 years of age or older
  • Moderate to severe pain within eight (8) hours following completion of the required bunionectomy surgery

Exclusion Criteria:

  • Allergy to shellfish
  • Signs of nasal congestion, nasal polyps, mucosal lesions of the nostrils, postnasal drip of any etiology or any clinically significant nasal pathology that may affect the absorption of study medication or the assessment of safety.
  • Chronic respiratory insufficiency such that treatment with an opioid analgesic is contraindicated
