Compositions and methods for safe treatment of rhinitis
Methods for treating rhinitis in a subject are provided herein. The methods of the present invention comprise intranasal administration of a topical composition comprising a purified botulinum neurotoxin, a carrier and a viscosity modifier to one or more inner surfaces of the nose. The methods disclosed herein provide alternative methods for delivery of botulinum neurotoxin to the nasal anatomy for the treatment of rhinitis.
1. A method for treating rhinitis, the method comprising
intranasally administering a therapeutically effective amount of a botulinum toxin composition to a patient in need of treatment; wherein said botulinum toxin composition comprises a purified 150 kDa botulinum neurotoxin isolated from botulinum toxin type A;
a carrier molecule comprising a polypeptide having the amino acid sequence RKKRRQRRR-Q-(K) 15 -Q-RKKRRQRRR (SEQ ID NO: 18); and
a viscosity modifier in the form of a gel or a solution that forms a gel upon an increase in temperature;
wherein said intranasal administration provides a dose of the purified botulinum neurotoxin of 250 U to 12,500 U to said patient.
2. The method according to claim 1 wherein said intranasal administration provides a dose of the purified botulinum neurotoxin of about 1,250 U to said patient.
3. The method according to claim 1 , wherein the concentration of said botulinum toxin composition is 6,250 U/mL.
4. The method according to claim 1 , wherein the viscosity modifier agent is poloxamer 407.
5. The method according to claim 1 , wherein said composition is applied using a single intranasal application for a duration of 5 seconds to 60 minutes.
6. The method according to claim 1 , wherein said composition is applied using a single intranasal application for a duration of 30 seconds to 45 minutes.
7. The method according to claim 1 , wherein said composition is applied using a single intranasal application for a duration of 1 minute to 30 minutes.
8. The method according to claim 1 , wherein said composition is applied using a single intranasal application for a duration of 30 minutes.
