Abstract

Compositions and methods for treatment, prevention, or amelioration of one or more symptoms of bronchoconstrictive disorders are provided. The compositions provided herein are nebulizable compositions comprising quaternary ammonium muscarinic receptor antagonists. The compositions are suitable for direct administration to a patient in need thereof via a nebulizer. Also provided are kits which comprise of the nebulizable composition of the invention in combination with a nebulizer. Also provided is a method of treating, preventing, or amelioration of one or more symptoms of bronchoconstrictive disorders by administering a therapeutically effective amount of the nebulizable composition of the invention via the use of a nebulizer to a patient in need thereof with minimal to no exposure of the nebulizable composition to the body surface of the patient.

Claims

1-8. -8. (canceled)

9. A method of treatment, prevention or amelioration of one or more symptoms of diseases or disorders associated with bronchoconstriction which comprises delivering a nebulizable composition which comprises:

(a) a quaternary ammonium muscarinic receptor antagonist in a concentration based on the ammonium of between about 0.0005% and about 5% by weight;

(b) a pharmacologically acceptable fluid; and

(c) a pharmacologically acceptable preservative, wherein the pH of the preparation is adjusted between about 2.0 to about 4.5 with an acid and the quaternary ammonium muscarinic receptor antagonist is dissolved in the fluid and optionally includes a pharmacologically acceptable complexing agent, stabilizer, a pharmacologically acceptable cosolvent, or other pharmacologically acceptable adjuvants and additives;

via a nebulizer, wherein the administration of the nebulizable composition by the nebulizer results in minimal exposure of the nebulized composition to the body surface of the patient.

10. The method of claim 9, wherein the body surface of the patient is the face and eyes.

11. The method of claim 10, wherein the loss of quaternary ammonium muscarinic receptor antagonists delivered to the mouth and lungs of the patient is less than 0.001% w/w.

12. The method of claim 11, wherein the nebulizer allows for the release of the nebulized composition upon inhalation by the patient and ceases release of the nebulized composition when inhalation has ended.

13. The method of claim 12, wherein the nebulizer is a breath actuated nebulizer.

14. The method of claim 13, wherein the quaternary ammonium muscarinic receptor antagonist is an ipratropium or tiotropium compound.

15. The method of claim 14, wherein the tiotropium compound is tiotropium bromide.

16. The method of claim 15, wherein the nebulizable composition further comprises an additional compound for the treatment of bronchostriction which is selected from the group consisting of a β

₂-adrenoreceptor agonist, a dopamine (D₂) receptor agonist, a steroidal anti-inflammatory agent, an anticholinergic agent, an IL-5 inhibitor, an antisense modulator of IL-5, a tryptase inhibitor, a leukotriene receptor antagonist, a 5-lapoxygenase inhibitor, an anti-IgE antibody, an antihistamine, an anti-allergic agent and mixtures thereof.

17. The method of claim 15, wherein the nebulizable composition is contained in a unit dose vial.

18. The method of claim 15, wherein the nebulizable composition are administered once a day administration prior to the patient going to sleep.
