This invention relates to novel pharmaceutical compositions for inhalation comprising separately, sequentially or together, drugs having amine in the form of a dry powder in admixture with a pharmaceutically acceptable carrier, other than lactose, and its use in the treatment of respiratory condition selected from asthma, chronic obstructive pulmonary disease (COPD) and other obstructive airways diseases.
In addition, the present invention relates to novel pharmaceutical compositions for inhalation based on combinations of long acting muscarinic antagonists, long acting beta agonists, short acting beta-2 agonists, corticosteroids or a combination of two or more of them with drugs having amine.
Amines are organic compounds and functional groups that contain basic nitrogen atom with alone pair. Amines are derivatives of ammonia, wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group. Therefore drugs having amines can be selected from the group comprising aclidinium, glycopyrronium, daratropium, indacaterol, vilanterol, carmeterol, olodaterol or pharmaceutically acceptable salts, or esters thereof, or in enantiomerically pure form or as a racemic mixture.
Most dry powder inhaler (DPI) formulations rely on lactose as a carrier. However, lactose cannot be used for compounds that interact with the reducing sugar function of the lactose. Such drugs are the ones having amine groups, as described above, especially the ones having primary or secondary amine.
Another disadvantage can be the Maillard reaction which results from a chemical reaction between an amine group and a reducing sugar. Water content (humidity) and temperature are found to influence the degradation.
Thus, there is a need in the art to look for alternative carriers, other than lactose, that still possess the positive aspects but overcome the above mentioned disadvantages of lactose.
Other sugars may comprise but not limited to mannitol, glucose, trehalose, cellobiose, sorbitol and maltitol as potential carriers; especially it is mannitol.
In prior art, there are several patents and compounds used for the treatment of asthma but all these compounds include lactose as a carrier. None of them comprise mannitol as carrier.
Additionally, carriers are used as a flow aid and facilitate the dose of the active into the lungs. Therefore the properties of the particles of the carrier play an important role in the formulation of dry powder inhaler (DPI). Thus, carriers should be carefully selected, designed and controlled for the use in a dry powder inhalation formulation.
Accordingly, formulations of dry powder Inhalers (DPI) must fulfill a set of requirements, whereby in particular the following are to be considered:
Content Uniformity of the Active Drug:
In a single dose system, each capsule or blister needs to contain the same amount of drug. In a multi dose system, the same amount of drug must be released every time it is administered, to guarantee that the patient receives the same dose each time. The presence of carrier, should promote the content uniformity even in a low-dosage medication.
Flowability:
The design of the device, the characteristics of the active and the filling platform to be used will determine the appropriate characteristics of the carrier that will be needed. The flow properties of the formulation will be important to ensure that the overall device functions in the correct way and provides consistent performance. The choice of carrier is essential in ensuring that the device works correctly and delivers the right amount of active to the patient. Therefore to use mannitol as a carrier in two different particle sizes (fine and coarse) is essential.
Dose Consistency:
DPI devices have to show a consistent dose uniformity in order to guarantee that all doses from the device contain the correct quantity of the active. Regardless of a patient's inhalation ability, it is essential that the dose released by the DPI device is exactly the same every time. Therefore, using mannitol as a carrier with the right properties in the formulation assists dose-consistent delivery.
Accordingly, in order to penetrate into the deep lungs the active particles will have a particle size less than 10 microns and often lower than 4 microns. These small drug particles will have a tendency to agglomerate. By using the appropriate carrier (such as mannitol) this drug to drug agglomeration can be prevented. Furthermore, the carrier (such as mannitol) will help to control the flowability, the drug release from the device and helps to ensure the correct and consistent dosage of the active that reaches the lungs.
Additionally, the formulation should be a homogeneous mixture where the drug particles adhere to the carrier. The adhesion should not be too strong as the drug will not be able to release from the carrier particle during inhalation. Furthermore, a low dose of powder should be filled into the device and the drug should always be released in the same way. One of the main important parameters for the formulation is the particle size of the carrier. Therefore, it is found that using the right ratio of the fine (small) and coarse (large) particles of the selected carrier in the present formulations of the invention is essential.
To fulfill all these requirements the formulations of DPIs needs to be adapted in particular by a careful selection of the carriers used. In order to meet these requirements, the inhalable, fine or microfine particles of active compounds are mixed with carriers. By means of the mixing process, the particle size of the carrier can also be changed such that a certain proportion is inhalable. The particle size of the carrier employed depends on the requirements and specifications of the powder inhaler which is intended for the administration of the formulation. It is true for these mixtures that during all required processing, transport, storage and dosage operations no segregation must take place, i.e. the active compound particles must not detach from their carrier particles. During dispersion in the inhaler, induced by the respiratory flow of the patient, the active compound particles, however, must be detached as effectively as possible, i.e. as quantitatively as possible, in order to be inhaled.
Thus, there is still a need for carriers that are able to overcome the problems mentioned above and the problems related with interaction of carrier between the drugs having amine and furthermore the problems related to pulmonary administration of drugs. This invention also proposes the possibility to obtain different compositions and composition of combinations for pulmonary administration having satisfactory properties in terms of increasing drug deposition or accelerating drug release rate in a safe and effective way.
This invention relates to novel pharmaceutical compositions for inhalation comprising separately, sequentially or together, drugs having amine in the form of dry powder in admixture with a pharmaceutically acceptable carrier, other than lactose which doesn't interact with the drugs especially having an amine group. The present invention further relates its use in the treatment of respiratory condition selected from asthma and chronic obstructive pulmonary disease (COPD) and other obstructive airways diseases.
Accordingly, the main object of the present invention is to provide pharmaceutical compositions for inhalation which is stable throughout the shelflife, in other words, which prevents any chemical reaction between an amine group and reducing sugar which may cause degradation of the active and furthermore resistant to humidity and temperature which may occur during the manufacturing process.
Another main object of the present invention is to provide pharmaceutical compositions for inhalation having an adequate content uniformity of the active in order to guarantee that the patient receives the same dose each time even in low-dosage formulations.
Another object of the present invention is to obtain the dose consistency of the active in order to guarantee that all doses from the device contain the correct quantity of the active. Using the carrier with the right properties and the right ratio in the formulation assists dose-consistent delivery. According to this preferred embodiment, the weight ratio of the fine carrier particles to coarse carrier particles, is between 0.01-0.25 by weight, preferably it is between 0.05-0.20 by weight.
According to a further embodiment of the invention, the fine carrier particles of the said pharmaceutically acceptable carrier have a particle diameter of d10 between 1.0-4.0 μm, d50 between 4.0-7.0 μm and d90 between 7.0-15.0 μm. The coarse carrier particles of the said pharmaceutically acceptable carrier have a particle diameter of d10 between 10.0-50.0 μm, d50 between 50.0-75.0 μm and d90 between 75.0-250.0 μm.
The coarse carrier particles are used to prevent (re)agglomeration of the fine particles of active. To provide this effect, carrier with a particle size of approximately ten times that of the active is used. Generally, a monolayer of the active particles is formed on the larger carrier particles. Since the active and carrier will have to be separated during inhalation, the shape and the surface roughness of the carrier particles is of significant importance.
Carrier particles with a smooth surface will separate from the active more easily than highly porous particles of equal size.
The fine carrier particles are used to help the active to reach the lungs in a safer way and higher doses. Because the surface energy is normally not equally spread over the carrier particle, the active will tend to concentrate on higher energy sites. This can make separation of the active from the carrier following pulmonary delivery more difficult, especially for low dose formulations. The presence of fine carrier particles, smaller than 10.0 micron or 5.0 micron, will help to prevent this, as the high energy sites will be occupied by the fine carrier particles and the active will tend to attach to the low energy sites. It is found that lung deposition will increase with an increasing fraction of fine carrier particles. Accordingly a reduction in particle size (having finer particles) increases the fluidization energy and this enhances the increase of the amount of drug particles that will get into the lung.
In this invention, the term “fine particles” means the fraction of active particles being less than 5.0 μm when assessed by a cumulative volume size distribution as tested by any conventionally accepted method such as the laser diffraction method.
The drug particles will then adhere to the lower adhesion sites and will be easier released during inhalation. With the addition of fines also the surface area increases significantly and the payload will be reduced. When the fine carrier particles are slightly coarser then the drug particles it could eliminate the friction forces between drug and carrier/mannitol in the mixing process.
Another object of the present invention is to obtain good flowability of the formulations to ensure that the right amount of the active is delivered by the devices for DPIs. In other words, in order to guarantee consistent production of the formulations, mechanical filling of the powder inhaler, correct dosage and release by the powder inhaler the present invention provides free-flowing formulations by selecting the right carrier.
Another object of the present invention is to prevent agglomeration by using appropriate carrier, other than lactose. Active particles have fine or sometimes microfine particles in order to penetrate into the deep lungs. Thus, these small drug particles will have a tendency to agglomerate.
In a preferred embodiment according to the present invention, the pharmaceutically acceptable carrier, other than lactose, is selected from the group comprising mannitol, glucose, trehalose, cellobiose, sorbitol, maltitol or a combination of two or more of them.
As a further embodiment, the carrier may be a combination of mannitol and glucose, or mannitol and trehalose, or mannitol and sorbitol, or mannitol and cellobiose, or mannitol and maltitol.
In a more preferred embodiment, the invention suggests to use mannitol as a carrier, more specifically to use spray-dried mannitol to achieve the best results.
In an ideal drug-carrier system, the adhesion of the active to the carriers is strong enough to prevent demixing during filling, handling and storage, but not so strong, since the active and carrier will have to be separated during inhalation. Therefore the shape and the surface roughness of the carrier particles is of significant importance. It is found that spray-dried mannitol particles will separate from the active more easily than highly porous particles of equal size. Because spray dried mannitol produces more spherical particles and a smooth surface. Such particles are characterized by a lower area of contact and a smaller, more homogeneous particle size distribution that result in a higher respirable fraction than mechanically micronized carriers. One of the advantages for using spray-dried mannitol is to achieve particle diameters of several micrometers with a narrow particle size distribution. This ensures, assuming an appropriate diameter, a maximum deposition of the embedded drug in the tracheo-bronchial and deep alveoli regions at normal inhalation rates. Moreover, spray-dried mannitol exhibited a narrow particle size distribution which means the ratio between the median particle size (d50) and d90 which is equal to or greater than 0.40. Preferably, the ratio between the median particle size and d d90 is between 0.45 and 0.50, more preferably it is 0.50 and 0.70.
Additionally, this narrow particle size distribution also applies to mannitol in the compositions of the present invention which is equal to or greater than 0.40. Preferably, the ratio of narrow particle size distribution is between 0.45 and 0.50, more preferably it is 0.50 and 0.70.
According to a preferred embodiment of the present invention, the average particle diameter (d50) of the drugs having amine is between 1.5-2.5 μm, and the amine is primary amine and/or secondary amine.

Asthma, chronic obstructive pulmonary disease and other related disorders have been known to be treated with beta-2 adrenergic receptor agonists as they provide a bronchodilator effect to the patients, resulting in relief from the symptoms of breathlessness. Beta-2 adrenergic receptor agonists can be short acting for immediate relief, or long acting for long-term prevention, of asthma symptoms. Long actings are long acting beta agonists (LABA) whose effect lasts for 12 hours or more. In a preferred embodiment, LABAs are selected from the group comprising salmeterol, formoterol, arformoterol, indacaterol, olodaterol, vilanterol, carmoterol, bambuterol or a pharmaceutically acceptable salt or ester thereof, or in enantiomerically pure form or as a racemic mixture or a combination of two or more of them. Preferably LABAs can be salmeterol xinofoate, arformoterol tartarate, indacaterol tartarate, olodaterol hydrochloride, vilanterol trifenatate, carmoterol hydrochloride, bambuterol hydrochloride, formoterol fumarate or a combination of two or more of them.
Short actings are short acting beta-2 agonists (SABA). They are bronchodilators. They relax the muscles lining the airways that carry air to the lungs within 5 minutes, increasing airflow and making it easier to breathe. They relieve asthma symptoms for 3 to 6 hours. They do not control the inflammation. In a preferred embodiment, SABAs are selected from the group comprising salbutamol, levosalbutamol, terbutaline, pirbuterol, procaterol, fenoterol, biltolterol, ritodrine, metaproterenol or a pharmaceutically acceptable salt or ester thereof, or in enantiomerically pure form or as a racemic mixture or a combination of two or more of them. Preferably SABAs can be salbutamol sulphate, salbutamol hemi-sulphate, levosalbutamol sulphate, terbutaline sulfate, pirbuterol hydrochloride, pirbuterol acetate, procaterol hydrochloride, fenoterol hydrobromide, bitolterol mesylate, ritodrine hydrochloride, metaproterenol sulfate or a combination of two or more of them.
Whilst it is also known that, beta-2 agonists provide symptomatic relief of bronchoconstriction in patients, another component of asthma, i. e. inflammation, often requires separate treatment. According to this, involves treatment with a steroid. Treatment with an inhaled corticosteroid is considered one of the most potent and effective therapies currently available for persistent asthma. In a preferred embodiment, inhaled corticosteroids are selected from the group comprising fluticasone, ciclesonide, budesonide, mometasone, beclomethasone, triamcinolone, flunisolide, dexamethasone or a pharmaceutically acceptable salt or ester thereof, or in enantiomerically pure form or as a racemic mixture or a combination of two or more of them. Preferably, the corticosteroids can be fluticasone propionate, fluticasone furoate, ciclesonide, budesonide, mometasone furoate, beclomethasone dipropionate, triamcinolone acetonide, flunisolide acetate, dexamethasone sodium phosphate or a combination of two or more of them.
Bronchoconstriction and inflammation are also associated with bronchial plugging with secretions, which may be treated with long acting muscarinic antagonists (LAMA). In a preferred embodiment LAMAs are selected from the group comprising tiotropium, glycopyrronium, ipratropium, aclidinium, oxitropium or a pharmaceutically acceptable salt or ester thereof, or in enantiomerically pure form or as a racemic mixture or a combination of two or more of them. Preferably the LAMAs can be tiotropium bromide, glycopyrronium bromide, glycopyrronium acetate, ipratropium bromide, aclidinium bromide, oxitropium bromide or a combination of two or more of them.
According to this preferred embodiment of the present invention, the said pharmaceutical compositions may further comprise one or more additional active agents selected from long acting muscarinic antagonists, long acting beta agonists, short acting beta-2 agonists, inhaled corticosteroids or a combination of two or more of them.
To assist better patient compliance, combination products are still needed. It would be highly desirable, however, to provide a combination therapy suitable to reduce bronchial inflammation, bronchial constriction and bronchial secretions in a single product or dosage form. It would also be desirable to provide such a combination product or composition in a form whereby the correct dosage of the various components is easily and safely administered.
Therefore, in a preferred embodiment of the invention, the pharmaceutical compositions comprise the drugs having amine and long acting muscarinic antagonists, or comprise the drugs having amine and long acting beta agonists, or comprise the drugs having amine and short acting beta-2 agonists, or comprise the drugs having amine and inhaled corticosteroids.
