Description

A SOLID ORAL PHARMACEUTICAL FORMULATION THAT CONTAINS TICAGRELOR Field of the Invention The present invention relates to a solid oral pharmaceutical formulation containing ticagrelor as the active pharmaceutical constituent and a method of preparing this formulation.
Background of the Invention The compound ticagrelor with the chemical name (1S, 2S, 3R, 5S) -3- [7 - [[(IR, 2S) -2- (3,4-difluorophenyl) -cyclopropyl] amino] -5- (propylthio) -3H-1,2,3-triazolo [4,5-d] pyrimidin-3-yl] -5- (2-hydroxyethoxy) -1,2-cyclopentanediol, which is represented by the formula (I), (I) it was described generically in WO 1999/005143 and specifically mentioned in EP 1135 391. This document also describes a method for its preparation, as well as the use of ticagrelor in the treatment or prevention of myocardial infarction, stroke, diseases of peripheral vessels, et cetera. WO 2001/092262 describes 4 polymorphs and an amorphous form of ticagrelor. WO 2011/067571 discloses co-crystals with various coforms such as glycolic, salicylic, succinic, malonic and 4-hydroxy-3-methoxybenzene carboxylic acid.
The pharmaceutical formulations have been described in 2 applications of the company Astra Zeneca, WO 2008/024044 and WO 2008/024045. WO 2008/024044 discloses a solid formulation comprising one or more fillers, one or more binder substances, preferably one or more disintegrating agents and preferably one or more lubricants. According to Example 1 of WO 2008/024044 the sodium salt of carboxymethyl starch was used as a disintegrating agent in the amount of 3% by weight. The document does not mention any example where a disintegrating agent would not be used. WO 2008/024045 discloses a very similar solid formulation comprising one or more fillers, one or more binder substances, preferably one or more disintegrating agents and preferably one or more lubricants. This document indicates that the use of disintegrating agents is necessary. The particular examples mentioned in the document they contain 2-6% by weight of a disintegrating agent, which is the sodium salt of carboxymethyl-starch.
WO 2011/076749 deals with the particle size of ticagrelor which was used in the formulation since ticagrelor is well known as a poorly soluble compound. In the cited examples of this application, disintegrating agents were used in amounts in the range of 4-6% by weight.
Ticagrelor is sold under the brand name Brilique for the prevention of arteriotrombotic events in the form of coated tablets. The commercialized formulation also contains the sodium salt of carboxymethyl starch as the disintegrating agent.
Detailed description of the invention This invention relates to a solid oral pharmaceutical formulation containing ticagrelor with the chemical name (1S, 2S, 3R, 5S) -3- [7 - [[(IR, 2S) -2- (3,4-difluorophenyl) cyclopropyl] ] amino] -5- (propylthio) -3H-1,2,3-triazolo [4,5-d] pyrimidin-3-yl] -5- (2-hydroxyethoxy) -1,2-cyclopentanediol, which contains in addition at least one non-hygroscopic filler material and / or at least one non-hygroscopic binder substance which does not have a disintegrating effect.
Non-hygroscopic filler means a water-soluble filler material, sugar alcohols are generally preferred, such as glucose, fructose, sucrose, lactose monohydrate, lactose anhydrous, raffinose, isomaltose, trehalose, dextrates, mannitol, erythritol, sorbitol, maltitol, xylitol, lactitol , compressible sugars. Hydroxypropylcellulose or maltose, for example, can be used as the non-hygroscopic binder substance. The composition according to this invention preferably contains 0.5-30% by weight of the binder, preferably 1-7% by weight of the binder and more preferably 2-4% by weight of the binder.
The term non-hygroscopic, used in this invention, refers to a material that has a low capacity to receive and retain water. Or, rather, the term non-hygroscopic refers to a material having an equilibrium moisture content of less than 6% by weight. This value is determined by Dynamic Vapor Sorption (DVS) at a relative humidity of 60% and a temperature of 25 ° C. The equilibrium moisture content is determined based on the isothermal sorption curve measured using the DVS method at 60% relative humidity and 25 ° C temperature.
An expert in the field knows that the use of agents Disintegrants in a formulation need not have an impact on the increase of biological availability of the active substance. This property is more influenced by sufficient humidification of the active substance that is present in the formulation. If a composition can be prepared in such a way that it will dissolve quickly enough without the use of disintegrating agents, the disintegrating agents only become a superfluous constituent that has no real effect.
The disintegrating agents represent a class of excipients that are generally considered as special excipients. The price of special excipients, i.e. disintegrating agents, is much higher than the price of commonly used excipients such as fillers. The price of the disintegrating agents such as the sodium salt of carboxymethyl starch or the sodium salt of croscarmellose can normally be several times higher than the price of general fillers such as mannitol or calcium acid phosphate.
The manner in which the disintegrating agents act is not clear until now. The mechanisms assumed in the past include, for example, impregnation with water, swelling, shape memory, repellency to other constituents, heating during humidification. The ability of the disintegrating agents to carry water to the porous network of the tablet is essential for efficient disintegration. This explanation was provided by the Encyclopaedia of Pharmaceutical Technology, 3rd edition, Informa Healthcare USA, Inc., 2007. As a natural consequence of the ability to carry water to tablets, the disintegrating agents are generally hygroscopic or very hygroscopic materials. According to the Handbook of Pharmaceutical Excipients, 6th edition, Pharmaceutical Press, 2009, the sodium salt of croscarmellose and the sodium salt of carboxymethyl starch exhibit the same characteristics.
Due to the hygroscopic nature of the excipients it is necessary to pack the formulation of ticagrelor in PVC / PVDC bubble type packaging. The use of non-hygroscopic bubble-type packaging makes it possible to replace expensive PVS / PVDC with more affordable PVC bubble-type packaging. With regard to lower excipient costs and lower packaging costs it is desirable to prepare a formulation containing non-hygroscopic excipients that have no disintegration effect.
The document W02008 / 024045 describes that the use of a composition containing one or more materials of filler, one or more binder substances, preferably one or more disintegrating agents and preferably one or more lubricants is suitable for the efficient release of at least 90% ticagrelor. Contrary to the findings of the foregoing, it has been found that a ticagrelor composition with any known form of ticagrelor (crystalline, amorphous or in a co-crystal form) containing at least one non-hygroscopic filler material and / or at least a non-hygroscopic binder that does not exhibit the disintegration effect will achieve an efficient release of at least 90% ticagrelor.
The term "disintegrating agent", used in this document, refers to any material that swells or soaks in contact with water. The term disintegrating agent comprises, for example, the group of compounds such as: povidone, crospovidone, starch, pregelatinized starch, sodium salt of carboxymethylcellulose, hydroxypropyl starch, microcrystalline cellulose, calcium salt of carboxymethylcellulose, sodium salt of crosslinked carboxymethylcellulose, potassium salt of polacrilin, low substituted hydroxypropyl cellulose, sodium or calcium alginate, docusate sodium, methylcellulose, agar, guar gum, chitosan and alginic acid. The composition of ticagrelor conveniently contains nothing or less than 2% of a disintegrating agent.
In the most preferred embodiment the pharmaceutical composition of ticagrelor does not substantially contain disintegrating agent.
The ticagrelor composition contains a non-hygroscopic filler material. Generally, a water-soluble filler material is preferred. Suitable fillers are, for example, monosaccharides, oligosaccharides and sugar alcohols such as glucose, fructose, sucrose, lactose monohydrate, lactose anhydrous, raffinose, isomaltose, trehalose, dextrates, mannitol, erythritol, sorbitol, maltitol, xylitol and lactitol, compressible sugars, calcium acid phosphate dihydrate and their mixtures. Lactose, mannitol and xylitol are preferred.
The composition of ticagrelor contains a non-hygroscopic binder substance. Suitable binding substances are, for example, povidone, copovidone, powdered cellulose, crystalline or microcrystalline, silicone microcrystalline cellulose, cellulose derivatives such as hydroxymethylcellulose, hydroxyethylcellulose and hydroxypropylmethylcellulose, starch, pregelatinized starch, polymethacrylates and mixtures thereof. In a preferred composition, the ticagrelor formulation contains from 0.5 to 30% by weight of the binder substance, preferably from 1 to 7% and more conveniently from 2 to 4% by weight of the binder substance.
The ticagrelor composition typically contains at least one surfactant. Suitable surfactants are, for example, anionic, cationic, ampholytic and / or nonionic surfactants such as the sodium salt of lauryl sulfate, cetrimide, N-dodecyl-N, N-dimethyl-betaine, polysorbates (for example, Tweens ™). , poloxamers and their mixtures. The sodium salt of lauryl sulfate is the preferred compound. The surfactant is used, in the ticagrelor formulation, in an amount of 0.1 to 4.0% by weight, more preferably in the range of 0.5 to 2.0%.
The ticagrelor composition typically contains at least 1 lubricant and / or an antiadhesive compound selected, for example, from magnesium stearate, stearic acid, hydrogenated vegetable oil, hydrogenated castor oil, talc, sodium stearyl fumarate, silicon dioxide. colloidal, magnesium trisilicate and their mixtures. Especially preferred are stearic acid, magnesium stearate, sodium stearyl fumarate and colloidal silicon dioxide.
The ticagrelor tablet can be conveniently coated with any suitable coating. A suitable coating agent for ticagrelor tablets is selected, for example, from methylcellulose, hydroxypropylmethylcellulose, hydroxypropylcellulose, polymers of acrylic acid, ethylcellulose, cellulose acetate phthalate, polyvinyl acetate phthalate, hydroxypropylmethylcellulose phthalate, polyvinyl alcohol, sodium salt of carboxymethylcellulose, cellulose acetate, gelatin, methacrylic acid copolymers, polyethylene glycol, shellac, sucrose, dioxide titanium and carnauba wax. Polyethylene glycol, hydroxypropylmethylcellulose and polyvinyl alcohol are preferred.
Examples Example 1 Wet granulation Ticagrelor is granulated in wet conditions together with either lactose or xylitol monohydrate or mannitol or maltitol (either using granulation by means of kneading or with the use of a common granulator with a fluidized bed) with an aqueous solution of either hydroxypropylcellulose or maltose. The sodium lauryl sulfate is preferably added to the granulation solution. He The granulated material obtained is dried and sieved through a 1 mm mesh. The screened granulate material is then mixed with either lactose monohydrate or xylitol or mannitol or isomaltose or maltose in a suitable mixing device for 20 minutes. After this premixing, magnesium stearate is added to the mixture and the mixture is stirred for another 3 minutes so that a suitable tablet manufacturing mixture can be obtained. This mixture is then compressed into tablets in a rotary tablet manufacturing device.
Example 2 Dry granulation The ticagrelor was granulated under dry conditions together with mannitol or lactose monohydrate or xylitol and preferably with sodium lauryl sulfate in a rotary compactor with a variable aperture size. The granulated material obtained was sieved through a 1 mm mesh. The screened granulate material is mixed with either lactose monohydrate or xylitol or mannitol or isomaltose or maltose or lactitol in a suitable mixing device for 20 minutes. After the premixing, magnesium stearate is added to the mixture and the mixture is stirred for another 3 minutes so that a mixture ready for the manufacture of tablets can be obtained. This The mixture is then compressed into tablets in a rotary tablet making device.
Example 3 Direct compression Ticagrelor is mixed with lactose monohydrate or xylitol or mannitol or isomaltose or maltose or lactitol in a suitable mixing device for 20 minutes. After the premixing, magnesium stearate is added to the mixture and the mixture is stirred for another 3 minutes so that a ready mix for the manufacture of tablets can be obtained in a rotary tablet manufacturing device.
Example 4 Coating of the tablets The tablets obtained according to Examples 1 to 3 are conveniently coated with a common coating material The constituents of the coating mixture are dissolved or suspended in a sufficient amount of water to provide the coating solution Then, the tablets are coated with this solution in a suitable device and finally dried.
