The Pharmacokinetics of Ketorolac Tromethamine Administered Intranasally (IN) for Postoperative Pain in Children Aged 12 Through 17 Years

This was an open-label PK study in pediatric subjects who had undergone general surgery. Each subject's study participation consisted of a screening visit, a single-dose treatment with intranasal ketorolac (IN) tromethamine, and a follow-up visit. Following surgery, subjects received IN ketorolac 15 mg (weight \ or = 50 kg) when pain relief was indicated. For pain not relieved by the study drug, the subjects had access to an opioid analgesic administered by patient-controlled analgesia (PCA). Blood samples for pharmacokinetic analysis were obtained at specified time points following the dose of ketorolac.
