Background of the invention
Decongestants are vasoconstrictors that help reduce the swelling in nasal passages and ease the stuffiness and sinus pressure. Known decongestant drugs include pseudephedrine and phenylephrine. Some decongestants, such as pseudephedrine (as well as pharmaceutically acceptable acid additional salts, e.g., those of HCI or H2SO4) are recognized as safe therapeutic agents, effective for treating nasal congestion and are commonly administered comcomitantly with an antihistamine for treatment of nasal congestion associated with allergic rhinitis.
U.S. Patent No. 5,314,697 describes a formulation of a pseudoephedrine-loratadine once-a-day product, achieving a release rate profile for pseudoephedrine component over an extended period in excess of twelve hours while maintaining the safety and effectiveness of the antihistamine loratadine.
It has long been known that histamine plays a very important role in allergic-type diseases, such as allergic rhinitis, conjunctivitis, rhinoconjunctivitis, dermatitis, urticaria and asthma. Antihistaminic compounds acting at the Hi-receptor histamine level are useful for treating such conditions. In this sense, documents EP 0818454 A1 and EP 0580541 A1 as well as patent application EP14382576.8 disclose benzimidazole compounds with selective Hi antihistaminic activity and devoid of arrhythmogenic effects.
A particular compound with the above properties is the second-generation antihistamine 2-[4-(2-{4-[1-(2-ethoxyethyl)-1 H-benzimidazol-2-yl]-1-piperidinyl}ethyl)phenyl]-2-methyl propanoic acid, also known as bilastine, having formula: and developed by Faes Farma, Spain. Bilastine is a Hi antagonist benzimidazole compound with no sedative side effects, no cardiotoxic effects, and no hepatic metabolism. In addition, bilastine has proved to be effective for the symptomatic treatment of allergic rhinoconjunctivitis and urticaria.
U.S. Patent Nos. 4,990,535 and 5,100,675 disclose a twice-a-day sustained release coated tablet wherein the tablet coating comprises descarbethoxyloratadine and a hydrophilic polymer and polyethylene glycol, and the tablet core comprises acetaminophen, pseudoephedrine or a salt thereof, a swellable hydrophilic polymer and pharmaceutically acceptable excipients.
U.S. Patent No. 5,314,697 and international PCT publication WO0145668A2 disclose a once-daily extended release tablet, containing a matrix core comprising pseudoephedrine sulfate and a coating comprising loratadine and desloratadine, respectively. Mexican patent application MX 2011 005 899 A describes microspheres encapsulated in gelatin capsules. The microspheres comprise inert cores coated with a polymeric matrix comprising phenylephrine, in turn coated with an immediate release layer of bilastine.
International PCT application WO 94/09761 A1 discloses tablets containing a matrix core comprising pseudoephedrine wherein the core is coated with an acrylate coating and a coating comprising desloratadine.
However, no solution exists to the problem of providing a drug system comprising a decongestant drug and the antihistamine bilastine, let alone as a once-daily formulation, capable of a reproducible adequate release profile.
Summary of invention
Despite the existence of previous pseudoephedrine formulations, the inventors have found that when matrix core tablets comprising pseudoephedrine were prepared, these released the drug in a manner that the release profiles were either too steep or too flattened as a function of time. Importantly, the inventors have also observed that the results varied significantly between batches as the release profiles were not reproducible. Also, when alternative formulations of non-matrix core tablets comprising pseudoephedrine were covered by an external layer, the dissolution results were also surprisingly inadequate, as a great deal of variability occurred between each batch.
Facing these observations, the inventors have unexpectedly found that the claimed composition solves all of these problems. The present invention provides an oral dosage form comprising a decongestant drug and optionally bilastine, with a reproducible profile characterized by a controlled release of the decongestant over a period in excess of twelve hours and preferably at least 16 hours and, if present, an immediate release of bilastine after oral administration. In a particular embodiment, the oral dosage form of the invention further provides a short burst release of up to 50 wt% of the total amount of the decongestant drug within the first hour after ingestion.
Thus, in a first aspect, the present invention provides a multi-layer oral pharmaceutical composition comprising:
- a matrix core, comprising a decongestant and a combination of at least two cellulose derivatives selected from the group consisting of Cre alkyl celluloses, Cre hydroxyalkyl celluloses, C1-3 carboxyalkyl celluloses and microcrystalline cellulose; and
- a first layer covering said core, comprising a cellulose derivative selected from the group consisting of Cre alkyl celluloses, Cre hydroxyalkyl celluloses, C1-3 carboxyalkyl celluloses and microcrystalline cellulose.
The pharmaceutical composition of the invention comprises at least two pharmaceutical ingredients. Therefore, in a second aspect, the invention is directed at the pharmaceutical composition of the invention, for use in medicine.
Furthermore, the oral pharmaceutical composition of the invention is useful for treating patients showing the signs and symptoms associated with allergic and/or inflammatory conditions such as the common cold, as well as signs and symptoms associated with allergic and/or inflammatory conditions of the skin or upper and lower airway passages such as allergic rhinitis, seasonal allergic rhinitis and nasal congestion, to name a few.
In a third aspect, the present invention is directed at the pharmaceutical composition of the invention, for use in the treatment and/or prevention of a disorder or disease susceptible to amelioration by antagonism of Hi histamine receptor and/or decongestant responsive disease.
In a further aspect, the present invention is referred a process of preparation of the multi layer oral pharmaceutical composition of the invention.

Figure 6 shows the pseudoephedrine release profiles of the tablets prepared according to the invention (identified herein as tablet 1 , described in example 4 as formulation 2) and of comparative tablets.
In this example, comparative tablets 2, 3, 4 and 5 were prepared according to the procedure of example 3 except for their composition, which varied slightly as shown in detail in the table above and summarized as follows: Comparative tablets 2 (pseudoephedrine release profile depicted in figure 6 as “o”) corresponds to tablets that did not have ethylcellulose in the first layer. In this case, the pseudoephedrine profile was not controlled and almost all pseudoephedrine was released within the first 4 hours. The release profile was therefore not adequate. Comparative tablets 3 (pseudoephedrine release profile depicted in figure 6 as “·”) corresponds to tablets that did not have hydroxypropyl methylcellulose in the core. In this case, the pseudoephedrine profile was very slow and only half of the pseudoephedrine was released at 24 hours. The release profile was therefore not adequate. Comparative tablets 4 (pseudoephedrine release profile depicted in figure 6 as “n”) corresponds to tablets that were prepared with ethylcellulose in the core (mixed with HPMC) but without ethylcellulose in the first layer. This sample is similar to comparative sample 2 in the sense that it did not have ethylcellulose in the first layer. In this case, just as for sample 2, the pseudoephedrine profile was not controlled and almost all pseudoephedrine was released within the first 4 hours. The release profile was therefore not adequate.
Comparative tablets 5 (pseudoephedrine release profile depicted in figure 6 as “D”) corresponds to tablets that had the ethylcellulose in the first layer replaced with Eudragit RS 30 D. In this case, the pseudoephedrine profile was not controlled and more than 80% of the total pseudoephedrine was released within the first 6 hours. The release profile was therefore not adequate.
Example 6. Coated formulations, according to the invention
Preparation of the tablets In this example, 500 g cores with the composition,
Ingredient Mass (mg) Weight percentage ( wt%)
Pseudoephedrine hydrochloride 180 36,00
Metolose® 90 SH 4000 SR 135 27,00
Vivapur® 101 177 35,40
Magnesium stearate 5 1 ,00
PVP K30 3 0,60
Deionized water (for binding) were prepared according to the procedure of example 1, except that ethylcellulose was not added in the preparation of the cores.
First layer
The cores were then coated with three Ethylcellulose N-100 concentrations, so that the coating concentrations were 1,20 wt%, 1,30 wt%, and 1,40 wt%, the weight percentage being calculated on the basis of the final weight of the cores without coating. The coating procedure was as follows:
1) A 4 wt% Ethylcellulose N-100 ethanol (96 °) solution was prepared;
2) Coating the previously prepared tablets in a SAR LABORTECNIC coater.
This led to three tablets comprising increasing amounts of Ethylcellulose in the first layer. Second layer
The coated cores were then submitted to a second coating, comprising bilastine and pseudoefedrine. The procedure was conducted as follows:
20 mg of bilastine were micronized (D90 < 20 pm) and paddle mixed for 45 minutes with 60 mg of pseudoephedrine hydrochloride and 61 mg of Vivacoat® PA-1 P-000 in water (evaporated during coating). After sieving (300 pm), the resulting mixture was used for coating the coated cores obtained in the previous step.
Once coated, the final tablets comprised bilastine 4 wt%, pseudoefedrine 12 wt% and Vivacoat 12,2 wt%, the weights calculated on the basis of the final weight of the cores without coating.
Dissolution tests
Each dissolution test was conducted according to the conditions explained in Example 2.
Results
Figure 7 shows the pseudoephedrine release profiles of the tablets prepared according to the present example for each concentration of Ethylcellulose: 1 ,20 wt% “o”; 1,30 wt% and 1 ,40 wt% “D”. The profiles of these tablets were characterized by an immediate release of pseudoephedrine followed by the controlled release of the pseudoephedrine. Figure 7 also shows the release profile of the tablets according to example 4 (identified in Figure 7 as tablet 1 (■), described in example 4 as formulation 2).
