Description

FIELD OF THE INVENTION

[0002] This invention relates to novel orally administered pharmaceutical formulations of one or more active pharmaceutical ingredients (APIs), optionally comprising salts, complexes, prodrugs and metabolites thereof, further comprising cocoa powder, to the use of one or more active pharmaceutical ingredients (APIs), optionally comprising salts, prodrugs and metabolites thereof, for the manufacturing of a medicament to be administered orally for achieving a pharmacological effect, and to methods of medical treatment of humans or animals by oral administration of one or more active pharmaceutical ingredients (APIs), optionally comprising salts, prodrugs and metabolites thereof.

BACKGROUND

[0003] There is a need for orally administered pharmaceutical formulations of one or more active pharmaceutical ingredients (APIs) providing for a rapid, preferably intraoral uptake, such as sublingual and/or buccal uptake, and having sufficient masking of badly tasting ingredients.

PRIOR ART

[0004] In “Development of oral acetaminophen chewable tablets with inhibited bitter taste”, Suzuki et al, International Journal of Pharmaceutics 251 (2003) 123-132 is disclosed combined use of sucrose, cocoa powder and the commercial bittermasking powder mixture Benecoat BMI-40 as corrigent against bitter taste of acetaminophen. In reality the main taste-masking effect of the Suzuki et al formulation is though achieved through the lipid matrix. But, the lipid matrix used, Witepsol H-15, is normally used for suppositories and is not suitable for oral or peroral formulations. Further, the amount of acetaminophen in the formulations of Suzuki et al is well below the general therapeutic dose. In contrast to the present formulations the formulations of Suzuki et al are not intended for intraoral uptake, but for peroral administration and subsequent uptake in the gastro-intestinal tract. A therapeutically effective unit dose of acetaminophen is too high for being administered through uptake in the oral cavity.

[0005] Chocolate, which is different from cocoa powder as such, is very rarely used as an ingredient in pharmaceutical products, hitherto only in laxatives. One example is Ex-Lax® being chocolated laxative pieces marketed by Novartis comprising sennosides. Purex, a laxative wherein phenolphthalein was formulated with chocolate, was marketed in the 1950s.

[0006] It has now surprisingly been found that a rapid, preferably intraoral uptake of one or more APIs is achieved concomitantly with sufficient taste masking of badly tasting ingredients through use of a formulation comprising said one or more APIs and further comprising cocoa powder as taste masker, filler and texturizer.

SUMMARY OF THE INVENTION

[0007] The present invention provides an orally administered pharmaceutical formulation of one or more APIs, optionally comprising salts, complexes, prodrugs and metabolites thereof for achieving a pharmacological effect. The administration can be to a human being or to an animal.

[0008] It is a primary objective to provide a formulation for a rapid onset through essentially intraoral uptake of one or more APIs. With “rapid onset” is herein meant that a therapeutic effect is achieved within a short period of time, preferably in less than 1 hour, more preferably in less than 30 minutes, following administration.

[0009] The administration may be accomplished without the addition of liquid. Administration without added liquid is a big advantage in all those situations where e g clean water or other suitable liquid is not available, such as on travel. Also the administration is discreet being a big advantage e g at lectures and on the theater. Further, use of the present formulation, which should melt in the mouth rather than be swallowed, is of a great advantage to all those persons having difficulties in swallowing a traditional tablet. A particularly useful dosage form of the present invention is thus a formulation that disintegrates or melts in the mouth without need for drinking water or other fluid.

[0010] The formulation is a dosage form comprising a therapeutically effective amount of one or more APIs. It is preferred that the amount of the one or more APIs be lower than an amount causing significant side effects.

[0011] Also provided by the present invention are methods of use of formulations of the present invention for medical treatment of a human or animal subject. Other features of this invention will be in part apparent and in part pointed out hereinafter.

[0012] An object of the invention is to provide novel orally administered pharmaceutical formulations of one or more APIs comprising cocoa powder.

[0013] A second object of the invention is to provide methods for preparing said formulations

[0014] A third object of the invention is methods for using said formulations in therapy for medical treatment of a human or animal subject.

[0015] Formulations according to the present invention should preferably melt in the oral cavity, whereby intraoral uptake of the one or more APIs is favorized.

[0016] The invention is adapted for discreet self-administration. By “discreet self-administration” wherein is meant self-administration that does not draw attention to the existence of a need for therapy.

[0017] Further objects of the invention will become apparent to one skilled in the art, and still other objects will become apparent hereinafter from the specification and claims.

[0018] The main advantages provided by a formulation according to the present invention are:

[0019] 1) The formulation provides for a rapid onset through essentially intraoral uptake of the one or more APIs;

[0020] 2) The formulation does not require any added liquid at the time of administration;

[0021] 3) The formulation provides for good taste masking;

[0022] 4) The formulation does not give an immediate patient-perceived association with medicines, as do traditional tablets;

[0023] 5) The formulation provides for discreet self-administration;

[0024] 6) The formulation is easy to administer for persons having problems in swallowing;

[0025] 7) The formulation provides for increased bioavailability due to reduced first-pass metabolism;

[0026] 8) The formulation may provide for an association of pleasure.

DETAILED DESCRIPTION OF THE INVENTION

[0027] It is the primary object of the present invention to provide orally administered cocoa-powder-containing pharmaceutical formulations useful for medical treatment.

[0028] Cocoa powder is defamed as cocoa nib with some fat removed and ground into a powder. Cocoa nib is defamed as cocoa beans with the shell removed. Cocoa butter is defined as fat expelled from the center (kernels or nib) of cocoa beans. Cocoa powder is prepared from roasted cocoa beans. It is a complex compound, which consists of starch, cocoa butter, amino acids, proteins, xanthines, amines, mono- and polysaccharides, phospholipids, flavonoids, pyrazines, etc.

[0029] More specifically it is the object of the invention to provide such a formulation that disintegrates and/or melts in the oral cavity with or without the aid of salivary fluid or mechanical erosion, or a combination thereof after which the formulation may show adhesiveness towards the tissues in the oral cavity.

[0030] Preferably the formulation is such that it does not require addition of liquid at the time of administration.

[0031] Optional addition of buffering agents provides for a transient change in local pH of the saliva, which facilitates uptake in the oral cavity.

[0032] It has surprisingly been found that a sufficient taste masking of badly tasting ingredients is achieved through the use of cocoa powder. The cocoa powder acts as taste masker, filler and texturizer.

[0033] A general embodiment of a formulation according to the present invention has a weight of around 200-1000 mg and has the following composition (w/w):

	Amount
Ingredient	(%)	Function
One or more APIs (base, prodrug,	0.03-12	API
metabolite, salt or complex)
One or more lipid ingredients	30-60	Lipid

EXAMPLES

[0034] Below follows non-limiting examples on preparation of embodiments of the present invention.

Example 1

[0035] A formulation, weighing around 400 mg, is prepared having the following composition (w/w):

	Ingredient	Amount (%)	Function
	Eletriptan hydrobromide	5.0	API
	Hydrogenated soybean oil	43.55	Lipid ingredient
	Cocoa powder	18.00	Taste masker, filler,
			texturizer
	Mannitol	12.00	Diluent
	Maize starch	14.90	Diluent
	Aspartame	0.15	Sweetener
	Acesulfame-K	0.10	Sweetener
	Titanium dioxide	2.00	Coloring agent
	Sodium Chloride	0.60	Taste modifier
	Coffee and vanilla flavors	3.00	Flavoring agents
	Soy lecithin	0.70	Emulsifier

[0036] Cocoa powder may be used in a non-alkalized form and in an alkalized form. Both are useful in the present formulations. Alkalized cocoa powder is preferred when a somewhat milder taste is desirable.

[0037] A part of the hydrogenated soybean oil is melted. The solid components, i e the API if solid (eletriptan hydrobromide is solid), cocoa powder, mannitol, maize starch, aspartame, acesulfame-K, titanium dioxide, sodium chloride and the flavoring agents if solid, are added and mixed. A reduction of particle size of the solid components is performed by milling in a roll-refiner. If the solid components have already got the required particle size, e g by milling before the mixing with the fatty components, roll refining is dispensed with. After treatment in the roll-refiner the mixture is mixed with the rest of the melted fatty components or remelted, if solidified, and mixed with the rest of the melted hydrogenated soybean oil. A mixing of the melt is performed in a suitable mixer. The liquid components, i e the API if liquid (eletriptan hydrobromide is though solid and is handled as above), soy lecithin and the flavoring agents if liquid, are added. Tablets or other solid dosage forms are subsequently made using suitable techniques, such as molding, extrusion or congealing, including pastillation, when necessary after suitable preconditioning. Also other suitable manufacturing methods may be used.
