Abstract

The use of β-adrenergic inverse agonists provides a new and highly efficient way of treating a number of pulmonary airway diseases, including asthma, emphysema, and chronic obstructive pulmonary diseases. In general, such a method comprises administering a therapeutically effective amount of a β-adrenergic inverse agonist to the subject to treat the pulmonary airway disease. Particularly preferred inverse agonists include nadolol and carvedilol.

Claims

1. A method for treatment of pulmonary airway disease in a subject suffering from pulmonary airway disease comprising chronically administering a therapeutically effective amount of a β

-adrenergic inverse agonist to the subject to treat the pulmonary airway disease by action of inverse agonism to promote long-term upregulation of the population of β

-adrenergic receptors upon chronic administration of the β

-adrenergic inverse agonist, wherein the β

-adrenergic inverse agonist exhibits inverse agonist activity at the β

₂ receptor of bronchial tissue, wherein the β

-adrenergic inverse agonist is selected from the group consisting of nadolol, bupranolol, butoxamine, carazolol, ICI-118,551, levobunolol, metoprolol, and timolol, and wherein such chronic administration requires increasing dosages over time.

2. The method of claim 1 wherein the β

-adrenergic inverse agonist is nadolol.

3. The method of claim 1 wherein the β

-adrenergic inverse agonist is administered by a route selected from the group consisting of oral, sustained-release oral, parenteral, sublingual, buccal, insufflation, and inhalation.

4. The method of claim 3 wherein the β

-adrenergic inverse agonist is administered by the sustained-release oral route.

5. The method of claim 1 wherein the pulmonary airway disease is selected from the group consisting of asthma, bronchiectasis, bronchitis, chronic obstructive pulmonary disease, Churg-Strauss syndrome, pulmonary sequelae of cystic fibrosis, emphysema, allergic rhinitis, and pneumonia.

6. The method of claim 5 wherein the pulmonary airway disease is asthma.

7. The method of claim 5 wherein the pulmonary airway disease is chronic obstructive pulmonary disease.

8. The method of claim 5 wherein the pulmonary airway disease is emphysema.

9. The method of claim 1 wherein the β

-adrenergic inverse agonist is administered over time in a series of graduated doses starting with the lowest dose and increasing to the highest dose, wherein such graduated doses are determined by determination of the increase of receptor density.

10. The method of claim 9 wherein, when the highest dose is reached, the β

-adrenergic inverse agonist continues to be administered at that dose.

11. The method of claim 1 further comprising administering a therapeutically effective amount of an additional agent selected from the group consisting of:

a β

₂-selective adrenergic agonist;

a steroid;

an anticholinergic drug;

a xanthine compound;

an anti-IgE antibody;

a leukotriene modifier; and

a phosphodiesterase inhibitor in order to treat the pulmonary airway disease by action of inverse agonism to promote long-term upregulation of the population of β

-adrenergic receptors upon chronic administration of the β

-adrenergic inverse agonist, wherein the β

-adrenergic inverse agonist exhibits inverse activity at the β

₂ receptor of bronchial tissue.

12. The method of claim 11 wherein the additional agent is a β

₂-selective adrenergic agonist and the β

₂-selective adrenergic agonist is selected from the group consisting of albuterol, bitolterol, clenbuterol, clorprenaline, dobutamine, fenoterol, formoterol, isoetharine, isoprenaline, levabuterol, mabuterol, metaproterenol, pirbuterol, ritodrine, salbutamol, salmeterol, terbutaline, and the salts thereof.

13. The method of claim 11 wherein the additional agent is a steroid and wherein the steroid is selected from the group consisting of beclomethasone, budenoside, ciclesonide, flunisolide, fluticasone, methylprednisolone, prednisolone, prednisone, and triamcinolone, and the salts thereof.

14. The method of claim 11 wherein the additional agent is an anticholinergic drug and wherein the anticholinergic drug is selected from the group consisting of ipratropium bromide, tiotropium bromide, and oxitropium bromide, and the salts thereof.

15. The method of claim 11 wherein the additional agent is a xanthine compound and wherein the xanthine compound is selected from the group consisting of theophylline, extended-release theophylline, aminophylline, theobromine, enprofylline, diprophylline, isbufylline, choline theophyllinate, albifylline, arofylline, bamifylline and caffeine.

16. The method of claim 11 wherein the additional agent is an anti-IgE antibody and wherein the anti-IgE antibody is a monoclonal antibody or a genetically engineered antibody that is derived from a monoclonal antibody.

17. The method of claim 11 wherein the additional agent is a leukotriene modifier and wherein the leukotriene modifier is selected from the group consisting of ibudilast, montelukast, pranlukast, and zafirlukast, and the salts thereof.

18. The method of claim 11 wherein the additional agent is a phosphodiesterase IV inhibitor and wherein the phosphodiesterase IV inhibitor is selected from the group consisting of roflumilast and cilomilast, and the salts thereof.
