Description

GENERAL DESCRIPTION OF THE INVENTION

[0010] The drugs or medicaments administered orally are administered to the patient under various presentation or dosage forms, such as liquid solutions, emulsions or suspensions, in solid form as capsules or tablets (any solid moulded or compressed dosage form, including oblong pills), among other known dosage forms in the art.

[0011] The drugs administered in the form of tablets or capsules are usually considered as being fully ingested. Thus, the often unpleasant taste of the active substance is not taken into account in medical formulations, unless the purpose is to provide a means to prevent the taste is noticed during the short period of time in which the medicament remains in the mouth. Such means may include a thin coating and of rapid dissolution, or customizing the use of gelatin or jelly capsules (the outer layer of gelatin capsule maintains the active substance inside until the capsule has been swallowed), or simply a drug or medicament firmly compressed in a way that it doesn't start to disintegrate during the short period of time in which it is supposed to stay in the mouth.

[0012] Children and the elder, among other people, or animals, have difficulty in swallowing the whole dosage forms of medicaments, regardless of its formulation, whether by its flavor, size, rigidity, period of dissolution, etc.

[0013] Thus, in those cases where the dosage to be administered cannot be produced in a ready to use form, such as very small tablets or capsules, it is desirable to provide a liquid presentation form or a soluble form, in addition to tablets or capsules that are designed to be swallowed whole. Even when the pharmaceutical formulation can be formulated as a liquid it is also desirable to provide a solid form because it is usually more convenient, light and less fragile regarding transportation purposes.

[0014] A common issue with liquid or soluble forms of medication is their flavor, often unpleasant, and associated to the active substance, which is perceived by the consumer/patient during the period of time that it contacts with the mouth. Frequently, the taste of the active substance in a medicament is controlled and masked by adding flavoring ingredients to the formulation. For example, in the case of aspirin for children where the dosage is small enough so that the amount of flavoring agents required to mask the taste of medicinal formulation is also low, not requiring a big dosage form for the medicament. However, this flavor masking is usually achieved by the use of sugars and/or other harmful ingredients to the consumer's health condition.

[0015] The esophagus is a muscular tube that carries food from the mouth to the stomach, being located mainly at the level of the human's chest. Normally we don't perceive this organ, except when we swallow. However, if the internal coating (called mucosa) of the esophagus becomes inflamed, we may feel chest pain or difficulty in swallowing. This inflammation of the esophagus is called esophagitis.

[0016] Some common medication can cause chemical burn of the esophagus. Pills that have a greater probability to cause esophagitis include: aspirin, doxycycline, iron supplements, non-steroidal anti-inflammatory drugs, such as ibuprofen or naproxen, medicines for osteoporosis, such as alendronate or risedronate.

[0017] Dysphagia is a term that refers to the difficulty in swallowing (oropharyngeal dysphagia) and the sensation of solid food and/or liquids stuck in the throat or esophagus (esophageal dysphagia). This condition causes discomfort and difficulty in chewing and swallowing, which can lead to poor nutrition and also dehydration or in the case of the need of medication intake, this condition may impair the treatment and therapeutics. This is a worldwide problem that affects approximately 60% of the population in developed countries, especially the children and elderly.

[0018] Resisting and/or crying is the means used by many children to reject medication, which is normal, given its unpleasant taste or inadequate form of presentation, challenging both parents and doctors, and compromising the success of treatments. To aid the administration of drugs, in general, pharmaceutical companies chose the simplest way available: if the taste is bitter, just add sugar to make it more pleasant and easier to ingest. But this solution also brings negative consequences, since a large part of pediatric medicines contain an excessive amount of sugar (between 60% to 80%), some with more than 80% of total weight or volume, contributing to generating caries and also for the excess weight and diabetes in more than 50% of the children who take these medicines. One would not expect that a medicament could be so harmful. A child rarely likes medicines, but the majority of children often like sweets. The solution is to produce gum, lollipops, candy, drops, lozenges, chewing-gum and chocolates, among other sweets, comprising up to 100% natural and healthy ingredients, among other adaptable formulations, without synthetic sugars, lactose-free, gluten-free, without coloring agents or artificial preserving agents and adding them active substances for obtaining stable formulations to be comprised by medicaments to be easily administered to humans and animals, without the drawback of high sugar level in regular medicaments.

[0019] The adopted definition of an ingredient is any substance, including additives, used in the manufacture or preparation of formulations and drugs or medicaments according to the present invention, which remains in the final product, unchanged or in a modified form.

[0020] Natural Ingredients are usually foods that are minimally processed, or do not contain food additives or do not contain other additives, such as hormones, antibiotics, sweeteners, coloring agents, flavoring agents, and others which are not found in food in its original composition. The Codex Alimentarius from Food and Agriculture Organization of the United Nations (FAO) does not recognize the term natural but has a definition for organic food. A natural ingredient is that which is organic, that is, originates from conventional agriculture, such as fruit, vegetables and/or originating from animals and that have no harmful effect in a human or animal body.

[0021] A natural product is a mixture of several natural ingredients.

[0022] A harmless ingredient is that which does not impairs the health of its consumer/user, that does not cause harm; harmless and not dangerous.

[0023] An active substance is any substance with pharmacological activity or other direct effect in the diagnosis, such as: cure, relief, treatment or prevention of diseases, clinical conditions and their symptoms; or that could affect any function of the human body.

[0024] The present invention is intended to incorporate any active substance applicable and stable in ingestible formulations for administration to humans and animals, such as paracetamol, ibuprofen, acetylsalicylic acid, among other substances for analgesics, antipyretics, anti-conception, anti-inflammatory, anti-allergic, muscle relaxants, diuretics, etc.

[0025] A formulation or pharmaceutical dosage form is the final state presented by active substances after being submitted to the necessary pharmaceutical operations in order to facilitate its administration and optimize the desired therapeutic effect. The subjection of the active substances to pharmaceutical operations is necessary due to the fact that the majority of the active substances cannot be directly administered to the patient.

[0026] The pharmaceutical operations involve all preparations and implemented actions with the purpose of transforming an active substance, also called a drug or active principle, in a pharmaceutical form. In some cases only one single operation is used, however, for the obtaining of a pharmaceutical form, several pharmaceutical operations are frequently implemented, namely: [0027] Weighing [0028] Grinding [0029] Dissolution in appropriate solvent [0030] Incorporation [0031] Homogenization of the mixture [0032] Packaging [0033] Etc.

[0034] Medicament is a pharmaceutical product, technically obtained or prepared, with prophylactic, curative, palliative or for diagnostic purposes. Medicaments comprising the formulations of the present invention may be presented in the following forms: [0035] tablets [0036] capsules [0037] dragees [0038] pills [0039] solution [0040] suspension [0041] emulsion [0042] ovules [0043] ointments [0044] suppositories [0045] liniments

[0046] The casing of capsules may usually comprise starch or gelatin.

[0047] The choice of pharmaceutical formulation depends mainly: [0048] of the physical and chemical nature of the active substance; [0049] of its action mechanism; [0050] of the target site of the drug or medicament. [0051] of the dosageamount of active substance in the pharmaceutical form.

[0052] An excipient is defined as a pharmacologically inactive substance, used as a vehicle for carrying the active substance. In the formulation, it can act as a binding agent, disintegrating agent, ligand, lubricant, surfactant, solubilizing agent, suspension agent, thickening agent, diluent, emulsifier, stabilizer, preservative, coloring agent, flavoring agent.

[0053] The present invention refers to the formulation of medicines based on healthy, natural, gluten-free, lactose-free excipients without coloring agents or artificial preservatives.

[0054] Medicaments comprise mainly two elements, the active substance (that cures or attenuates the symptom(s) or the disease) and the excipient (which embodies the active substance). In the present invention the traditional excipient of a given medicament is replaced by healthy and natural sweet tasting elements (chocolates, lozenges, sweets, gum, among others). The manufacturing method of such formulations and medicaments should always be adapted and arranged to fit the optimal conditions of manufacturing the active substance and the selected excipient, by at least one of two main methods: inclusion on pre-production and inclusion on co-production.

[0055] The inclusion on pre-production, in a first phase, the sweet product/candy (whilst excipient) is completely produced, fulfilling the requirements of natural and healthy food and in the second phase the active substance is introduced (e.g. by injection within the excipient, compression, or by other means).

[0056] On inclusion by co-production, during phase 1 the sweet product (whilst excipient) is produced but not into its final presentation form (being kept in the liquid state, without solidification), complying with the requirements of natural and healthy, and in the second phase the active substance is introduced (by direct adding) and on a third phase, the excipient is solidified.

[0057] During inclusion on co-production, it is also possible to add the active substance during the manufacture stage of the sweet product (whilst excipient) together with the remaining ingredients comprised by the excipient.

[0058] The present disclosure regarding manufacturing methods are not limiting, other methods may be used, such as traditional methods of introducing active substances in excipients, or other useful methods which are also effective and easy to implement and perform, once they are optimized.

[0059] Scope of Use

[0060] For example, each healthy chocolate generates, on average, 25 calories, has no contraindications and even diabetics can eat it, because it does not contain sugar, or lactose, comprises more than 50% of cocoa, soya flour and is sweetened with naturally sweet plant extracts (without sugar), rendering it a good excipient for medicaments such as, for example, those which are based on iron (Fe), magnesium (Mg) or phosphorus (P).

[0061] Lollipops are an additional vehicle for drug administration. The sweet product dissolves slowly while in the mouth, releasing the drug for absorption. Lollipop with glutamine, for example, accelerates healing of aphthas and aphthous stomatitis. This pharmaceutical form is also particularly indicated for patients with swallowing difficulties, such as the elderly or cancer patients under treatment. Due to the a pleasant appearance and taste, this pharmaceutical form increases the patient's adherence to the treatment.

[0062] Gums are naturally flavored with fruit in order to minimize the characteristic unpleasant flavors of medicament's formulation components, and are capable of incorporating a great volume of substances. They are also good options for children who are over-weight, providing them with a large variety of flavors in order to render them more attractive.

[0063] The present invention provides medicament production in the form of sweet products (chocolates, candy, lozenges, gum, etc.) with pleasant flavor, such as fruit, cocoa, and others. This is an easier way to administer medication to human and animal patients, therefore allowing a more effective dosage routine and being less laborious for people who administrate medication.
