Technical Field of the Invention
The present invention is related to a novel combination of ciclesonide and antihistamines for use in drug therapy in particular in the treatment of allergic rhinitis. In particular the novel combination is adminis¬tered in the form of an aqueous pharmaceutical composition that contains ciclesonide and antihista¬mine and having an osmotic pressure of less than 290 mOsm.
Background Art
Allergic rhinitis is a common disorder and the number of patients is steadily increasing. The disease is caused by ambient airborne allergens, which cause an allergic inflammation within the nasal mucosa and it is often accompanied by conjunctivitis. According to the allergen, the allergic rhinitis is subdivided into seasonal allergic rhinitis (allergens like grass pollen, cedar pollen) and perennial allergic rhinitis (indoor allergens like mould, allergens from animals and house dust mite). Allergic rhinitis has a great impact on the quality of life. The patients suffer from an itchy and running nose, nasal blockage, head¬ache and fatigue. Allergic conjunctivitis is often linked to allergic rhinitis and requires co-treatment. The major symptoms of conjunctivitis are burning and itching eyes and lacrimation. The basic mechanisms involved in this disease are the same as for allergic rhinitis.
The current treatment of allergic rhinitis is mainly focused on symptomatic relief. Oral and to a lesser extent topical antihistamines are the most widely used remedies. Oral antihistamines alleviate the his¬tamine driven symptoms only. Allergen contact causes degranulation of mucosal mast cells and hista¬mine is released. Histamine is responsible for the itching and sneezing and the increase in nasal secre¬tion. Antihistamines block the binding of histamine to the histamine-H1-receptor and thereof the hista¬mine mediated symptoms. Beside this obvious pathway, the allergens cause an eosinophilic inflamma¬tion of the nasal mucosa, which is mainly responsible for symptoms like nasal hyperreactivity, nasal blockage and the fear of the so called change of floors, which means that an untreated allergic rhinitis can develop to sinusitis and asthma bronchiale.
Treatment with glucocorticoids is currently the only one therapy, which targets the underlying allergic inflammation. To avoid systemic side effects typically for glucocorticoids, e.g. immunosuppression, reduced protein synthesis, impaired growth in children, topical treatment with glucocorticoids is the pre¬ferred way of administration.
A disadvantage of nasal steroids is the slow onset of action and the need for continuous treatment. It takes 4-6 days of continuous treatment before a symptom relief can be observed. Therefore, the pa-


tients are recommended to begin to take glucocorticoids before the pollen season starts. The slow on¬set of action, the need of consequent treatment and the fear of steroid induced side effects have a negative impact on the use of intranasal steroids and patient's compliance.
Other medications available for the treatment are just for symptomatic relief, for example intranasal muscarinic antagonists (ipratropium to reduce nasal secretion), adrenoreceptor agonists (xylometha-zoline to reduce nasal congestion).
WO 97/01337 describes a nasal spray or nasal drops formulation comprising beclomethasone, flunisol-ide, triamcinolone, dexamethasone or budesonide in combination with the antihistamines levocabas-tine, azelastine or azatadine and sterile water,

WO 03/049770 discloses compositions and methods for treating rhinitis with H1 antago-nists/antiallergics and safe steroids.
US 5164194 is related to nasal formulations for azelastine. Detailed Description of the invention
Surprisingly it has now been found that combined administration of ciclesonide and at least one antihis¬tamine results in a very effective and safe treatment of symptoms accompanied with allergic rhinitis and/or allergic conjunctivitis. In particular by combined administration of the ciclesonide and the antihis¬tamine as hypotonic aqueous pharmaceutical formulation a rapid onset of action and quick symptom relief is observed without the fear of glucocorticoid like side effects. By administering such hypotonic aqueous pharmaceutical composition according to the invention to the nasal mucosa the active ingredi¬ents rapidly enter the nasal mucosa and have a very long retention time. Therefore very low doses of ciclesonide and a once-daily, maximal twice-daily treatment is necessary to achieve aneffective treat¬ment.


In one aspect the present invention therefore relates to the combined administration of ciclesonide and at least one antihistamine for the treatment of allergic rhinitis and/or allergic conjunctivitis. Another sub¬ject of the invention therefore is a pharmaceutical composition for the treatment of allergic rhinitis and/or allergic conjunctivitis comprising as active ingredients a combination of at least one antihistami¬ne, a pharmaceutically acceptable salt and/or a solvate or physiologically functional derivative thereof and ciclesonide, pharmaceutically acceptable salts of ciclesonide, epimers of ciclesonide in any mixing ratio with ciclesonide, solvates of ciclesonide, physiologically functional derivatives of ciclesonide or solvates thereof and a pharmaceutically acceptable carrier and/or one or more excipients.
It will be appreciated that the compounds of the combination may be administered simultaneously, ei¬ther in the same pharmaceutical formulation (hereinafter also referred to as fixed combination) or in different pharmaceutical formulations (hereinafter also referred to as free combination)'or sequentially in any order. If there is sequential administration, the delay in administering the second compound should not be such as to lose the beneficial therapeutic effect of the combination. As an example, both drugs may be provided separately as oral formulations, or one may be an oral preparation and the other an inhalant, or both may be provided in a form suitable for application to mucosa (nasal application). Administration may be at the same time. Or they may be administered either close in time or remotely, such as where one drug is administered in the morning and the second drug is administered in the eve¬ning.
Accordingly, the present invention also provides a method for the prophylaxis or treatment of allergic rhinitis and/or allergic conjunctivitis in a mammal, such as a human, which comprises administration of a therapeutically effective amount of a pharmaceutical formulation comprising at least one antihista¬mine or a pharmaceutical acceptable salt, solvate, or physiologically functional derivative thereof and ciclesonide or a pharmaceutical acceptable salt, solvate, or physiologically functional derivative thereof, and a pharmaceutical acceptable carrier and/or one or more excipients. In a preferred aspect, there is provided such a method, which comprises administration of a therapeutically effective amount of a combination comprising at least one antihistamine and ciclesonide, and a pharmaceutical acceptable carrier and/or one or more excipients.
The formulations include those suitable for oral, parenteral including subcutaneous, intradermal, intra¬muscular, intravenous and intraarticular, intranasal, inhalation (including fine particle dusts or mists which may be generated by means of various types of metered dose pressurised aerosols, nebulisers or insufflators), rectal and topical (including dermal, buccal, sublingual and intraocular administration) although the most suitable route may depend upon for example the condition and disorder of the recipi¬ent. In a preferred embodiment according to the invention the formulation is suitable for topical admini¬stration. In a preferred embodiment the formulation according to the invention is a formulation suitable for application to mucosa in the case of treatment of allergic rhinitis. In the case of treatment of allergic conjunctivitis a preferred formulation is a formulation suitable for conjunctival administration (application to the conjunctival sac). The formulations may conveniently be presented in unit dosage form and may

be prepared by any of the methods well known in the art of pharmacy. All methods include the step of bringing the active ingredients into association with the carrier, which constitutes one or more accessory ingredienls/excipients. In general the formulations are prepared by uniformly and intimately bringing into association the active ingredients with liquid carriers or finely divided solid carriers or both and then, if necessary, shaping the product into the desired formulation.
In a preferred embodiment the present invention relates to an aqueous pharmaceutical composition for the treatment of allergic rhinitis for application to the mucosa, comprising as active ingredients a combi¬nation of at least one antihistamine and ciclesonide. In particular the aqueous pharmaceutical composi¬tion is a sterile aqueous pharmaceutical composition.
The present invention further relates to an aqueous pharmaceutical composition for the treatment of allergic rhinitis for application to the mucosa comprising as active ingredients a combination of at least one antihistamine and ciclesonide together with one or more water-insoluble and/or water-low soluble substance and having an osmotic pressure of less than 290 mOsm. Preferably the osmotic pressure is 150 mOsm or lower, more preferably 72 mOsm or lower, more preferably 60 mOsm or lower, more pre¬ferably 40 mOsm or lower, more preferably 30 mOsm or lower and still more preferably 20 mOsm (e.g. 10 mOsm or lower).
According to the present invention it is not particularly required to add a substance for controlling osmo¬tic pressure (osmotic pressure-controlling agent) but when it is added any substance can be used. In the present invention, a substance for controlling osmotic pressure (osmotic pressure controlling agent) can be added to control osmotic pressure, specific examples of which include salts such as sodium chloride and water-soluble sugars such as glucose, with glucose being a particularly preferable exam¬ple.
In a preferred embodiment the pharmaceutical composition is a pharmaceutical composition as de¬scribed for ciclesonide in WO 01/28562 or WO 01/28563.
Thus in one aspect the present invention relates to an aqueous pharmaceutical composition for the treatment of allergic rhinitis for application to the mucosa, comprising as active ingredients a combina¬tion of at least one antihistamine and ciclesonide together with one or more water-insoluble and/or wa¬ter-low soluble substance and having an osmotic pressure of less than 290 mOsm.
The water-insoluble or water-low soluble substance may be any substance, and preferred examples include celluloses, more preferably crystalline celluloses and particularly preferred microcrystalline cel¬luloses.

Carboxymethyl cellulose so¬dium blended with microcrystalline cellulose, is an example of a combination of these water-soluble substance and water-insoluble substance that can be used in the present invention. Furthermore, in the case of adding these water-soluble polymer substances, the concentration of said substance is pref¬erably 1% w/w to 30 % w/w relative to the water-insoluble substance and/or water-low soluble sub¬stance.
In a preferred embodiment of the invention hydroxypropylmethyl cellulose is contained in the pharma¬ceutical compositions according to the invention. The hydroxypropylmethyl cellulose may be any grade, a specific example is hydroxypropylmethyl cellulose 2910. Although said hydroxypropylmethyl cellulose may be present at any concentration, its concentration is preferably from 0.001 % w/w to 30 % w/w, particularly preferably form 0.01 % w/w to 5 % w/w, more particularly preferably from 0.01 % w/w to 1 % w/w, and most preferably from 0.01 % w/w to 0.5 % w/w, relative to the total amount of composition.
A surfactant and/or wetting agent, although not essential in the present invention, can be added, spe¬cific examples of which include Polysorbate 80, glycerin monosterarate, polyoxyl stearate, lauro-macrogol, sorbitan oleate and sucrose fatty acid esters.
An effective amount of ciclesonide and the topical antihistamine used in the present invention can be determined according to the type and degree of the respective disease, as well as the age and body weight of the patient, and so forth. Preferably the pharmaceutical composition according to the inven¬tion is administered as one to four sprays per nostril once or twice a day. The dose of ciclesonide per actuation is expediently from 10 ug to 400 ug, preferably 20 ug to 200 ug.

Due to the unique galenic formulation, ciclesonide rapidly enters the nasal mucosa and has a very long retention time. Therefore, very low doses of ciclesonide and the once daily, maximal twice-daily treat¬ment is necessary to achieve an effective treatment. A low dose of ciclesonide in a hypotonic watery suspension in combination with a topical antihistamine (e.g. azelastine or levocabastine) results in a very effective and safe treatment of all symptoms accompanied with allergic rhinitis. A clear advantage of this combination is the rapid onset of action and quick symptom relief without the fear of glucocorti¬coid like side effects.
In another embodiment the present invention relates to a combination of ciclesonide with azelasine and ciclesonide is applied in a pharmaceutical composition as described for ciclesonide in WO 01/28562 or WO 01/28563 and azelastine is applied in a pharmaceutical formulation according to US 5164194.
When given to the nasal mucosa the formulation according to the present invention may be filled into plastic squeeze bottles or plastic or glass bottles, which are fitted with a metering atomising pump and a nasal adapter or with a suitable dropper. When given to the eye the formulation according to the pre¬sent invention may be filled into plastic squeeze bottles or plastic or glass bottles, which are fitted with a suitable dropper.
