Open Label, Three-Way Study to Assess the Absorption and Tolerability of Intranasal Ketorolac Tromethamine and to Assess the Effects of a Single Dose of Oxymetazoline Hydrochloride and Multiple Doses of Fluticasone Propionate on the Absorption and Tolerability of Intranasal Ketorolac Tromethamine in Participants With Allergic Rhinitis

Detailed Summary

This was an open label, three way study in participants with symptomatic allergic rhinitis. The following 3 treatments were administered to each subject during dosing periods 1, 2 and 3, respectively: * Treatment A: Single intranasal dose of 30 mg ketorolac tromethamine (one 15 mg spray into each nostril) on Day 1 of Period 1. * Treatment B: Single intranasal dose of oxymetazoline hydrochloride followed by a single intranasal dose of 30 mg ketorolac tromethamine (one 15 mg spray into each nostril) 30 minutes later on Day 1 of Period 2. * Treatment C: Seven days of treatment with intranasal fluticasone propionate (between Periods 2 and 3) followed by a single intranasal dose of 30 mg ketorolac tromethamine (one 15 mg spray into each nostril) on Day 1 of Period 3. Subjects remained resident in the Clinical Unit from Day 1 until the morning of Day 2 in each period and there was a washout period of 2 to 7 days between periods. A post study medical was performed within 7 days of Period 3. The objectives of this study were: * To assess the pharmacokinetics (PK) of intranasal ketorolac in participants with symptomatic allergic rhinitis. * To assess the effects of a single dose of intranasal oxymetazoline hydrochloride on the pharmacokinetics and tolerability of intranasal ketorolac in participants with symptomatic allergic rhinitis. * To assess the effects of chronic administration of fluticasone propionate on the bioavailability and tolerability of intranasal ketorolac in participants with symptomatic allergic rhinitis.
