Compositions for the treatment of gastrointestinal inflammation
Provided herein are methods for treating, preventing or alleviating the symptoms of and inflammation associated with inflammatory diseases and conditions of the gastrointestinal tract, for example, those involving the esophagus. Also provided herein are pharmaceutical compositions useful for the methods of the present invention.
1. A method of treating or alleviating esophageal inflammation or symptoms of esophageal inflammation in an individual comprising orally administering to said individual a stable oral pharmaceutical composition comprising:
a) a topically active corticosteroid, wherein the topically active corticosteroid is budesonide, fluticasone, mometasone furoate, ciclesonide, triamcinolone, beclomethasone, a pharmaceutically acceptable salt or ester thereof, or a combination thereof,
b) a liquid vehicle,
c) maltodextrin in an amount of about 0.05 g to about 2 g per mL of the composition and a carboxymethyl cellulose (CMC) in an amount of about 1 mg to about 150 mg per mL of the composition, and
d) an antioxidant,
wherein the stable oral pharmaceutical composition is chemically and physically stable, and wherein the pharmaceutical composition remains substantially uniform for at least 1 month, and wherein the pharmaceutical composition does not comprise fatty oils.
2. The method of claim 1 , wherein the corticosteroid is budesonide.
3. The method of claim 1 , wherein the corticosteroid is fluticasone propionate.
4. The method of claim 1 , wherein at least 10% of the stable oral pharmaceutical composition adheres to the esophagus for at least 15 seconds after oral administration of the stable oral pharmaceutical composition.
5. The method of claim 1 , wherein at least 10% of the corticosteroid adheres to the esophagus for at least 15 seconds after oral administration of the stable oral pharmaceutical composition.
6. The method of claim 1 , wherein at least 10% of the corticosteroid adheres to or is absorbed by the esophagus at least 15 seconds after oral administration of the stable oral pharmaceutical composition.
7. The method of claim 1 , wherein about 0.1 mg to about 20 mg corticosteroid per day is administered to said individual.
8. The method of claim 1 , wherein 0.3 mg to about 4 mg corticosteroid per day is administered to said individual.
9. The method of claim 1 , wherein the antioxidant is selected from ascorbyl palmitate, butylated hydroxyanisole, butylated hydroxytoluene, monothioglycerol, sodium ascorbate, sodium formaldehyde sulfoxylate, sodium metabisulfite, BHT, BHA, sodium bisulfate, vitamin E or a derivative thereof, propyl gallate, edetate (EDTA) disodium edetate, Diethylenetriaminepentaacetic acid (DTPA), Triglycollamate (NT), and combinations thereof.
10. The method of claim 1 , wherein the antioxidant comprises sodium ascorbate.
11. The method of claim 1 , wherein the corticosteroid is administered in a unit dose formulation for oral administration.
