Study Description

Brief 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.
