Topical agents for the treatment of sensory discomfort in the nasal cavity
View Patent ↗The present discovery pertains generally to the field of therapeutic compounds. More specifically the present discovery pertains to certain di-alkyl-phosphinoyl-alkanes as described herein, DIPA-1-8 and DIPA-1-9, and 2-6 and 2-7 that are collectively referred to herein as “DAPA compounds”, that are useful in the treatment of disorders (e.g., diseases) including: sensory discomfort (e.g., caused by inflammation, irritation, itch, or pain) in the nasal cavity. The applicant has found that localized delivery of DAPA compounds with a swab to the Kiesselbach's area of the human nose will relieve the discomforts of rhinitis and other nasal cavity discomforts.
1. A method of relieving sensory discomfort in a nasal cavity, comprising:
providing an aqueous liquid composition, the composition having a therapeutic amount of 1-[Diisopropyl-phosphinoyl]-nonane; and, topically applying the aqueous liquid composition to the Kiesselbach's area of a human nose in need thereof to relieve nasal discomfort caused by air pollutants, rhinitis, the common cold or rhinosinusitis.
2. The method of relieving sensory discomfort in the nasal cavity as in claim 1 , wherein the therapeutic amount of 1-[Diisopropyl-phosphinoyl]-nonane is 1 to 10 mg/mL of the composition.
3. The method of relieving sensory discomfort in the nasal cavity as in claim 2 wherein the aqueous liquid composition is saturating an absorbent material.
