Definitions
- the present invention relates to coatings for tablets for pharmaceutical, nutraceutical and/or veterinary use. More specifically, the present invention relates to flavoured coatings that have a pleasant mouthfeel. The present invention also relates to processes for preparing coated pharmaceutical and/or nutraceutical tablets and/or veterinary tablets.
- Pharmaceutically active agents such as drugs or medicaments can be used to treat diseases or for prophylactic purposes.
- Nutraceutically active agents can be used for a variety of medical and non-medical purposes including supplementing dietary intake, enhancing performance, and the like.
- Oral administration of active agents is the most common mode of administration. In many cases it is desirable to administer active agents as compressed (solid) tablets for oral administration due to reasons of stability, economy, simplicity, and convenience of dosing. Tablets typically deliver a pharmacologically effective amount of an active agent to the gastrointestinal tract of the human or animal to which they are administered.
- Tablets can have one or more coatings that provide a variety of benefits, including the masking of objectionable flavours or odors, protecting unstable tablet compositions, improving the ease with which the tablets are swallowed, providing protection of the tablets through the stomach with enteric coatings, improving the appearance of the tablets, improving the mouthfeel of the tablets, colouring the tablets, and the like.
- Numerous methods for coating tablets with one or more coatings are known. They include sugar coating, solvent film coating, aqueous film coating, delayed release coating and granule coating techniques.
- polymeric film coating agents Some of the most commonly used coatings today are polymeric film coating agents. Advantages of polymeric coatings include the ability to produce a tablet in which the coating comprises less than 5% of the weight, better resistance to chipping, and increased tablet strength. Polymers have been applied to tablets using both aqueous and non-aqueous solvents. Many tablet coatings are formed from low viscosity hydroxypropylmethylcellulose (HPMC) and an appropriate plasticiser. The coating is typically applied by a spraying system or device to a tablet in a coating process.
- HPMC low viscosity hydroxypropylmethylcellulose
- the present invention arises from the finding that the use of a powdered flavour composition, which can be obtained, for example, by spray drying a flavourant with a carrier, such as maltodextrin, provides certain manufacturing efficiencies and product benefits for pharmaceutical, nutraceutical and/or veterinary tablets having a flavoured coating.

- Maltodextrin is a polysaccharide that is widely used as a food additive and pharmaceutical excipient and is widely available commercially.
- the maltodextrin ideally has a Dextrose Equivalent (DE) of about 15 to about 20. As the DE of the maltodextrin increases, so does sweetness and solubility.
- DE Dextrose Equivalent
- materials having a DE of greater than about 20 are corn syrup solids and dextrose which are more hygroscopic. Dextrose is also less favoured by diabetics and consumers may also prefer "sugarless" products having fewer calories.
- the powdered flavour composition may contain flavourant in an amount from about 1% to about 20%, by weight, with the remainder being carrier and, optionally, other components.

- the powdered flavour composition may contain a sweetener, such as a natural or artificial sweetener.
- the powdered flavour composition may contain a gum, such as sodium carboxymethylcellulose, acacia gum or xanthan gum (e.g. Keltrol F). Gums can be added to improve mouthfeel as they rapidly swell when put in the mouth and quickly release the flavour from the coating by breaking it up.
- Benefits of using the powdered flavour composition and subsequently combining it with other components to form the tablet coating composition is that it becomes both a flavour and a functional ingredient, there are less ingredients to weigh out, and the powdered flavour composition is normally less volatile than if a liquid flavourant is used, which is useful for stability and manufacturability. Indeed, the volatility of liquid flavourants makes accurate dosing of the flavourant difficult under normal manufacturing conditions. Also, the solvent (or other volatile component(s)) of liquid flavourants can have detrimental effects on the tablet core when the tablets are coated because the flavour can tend to leach through to the tablet.
- a coating fluid containing the powdered flavour composition the viscosity of the coating fluid is greater than if a liquid flavourant is used and the film forming behaviour of the coating fluid is improved.
- Including a powdered flavour composition provides a film with good strength and adhesion.
- a powdered flavour composition in formulating the tablet coating composition gives rise to a coated tablet that may have improved gloss and/or mouthfeel compared to a coated tablet formed from a coating composition in which a liquid flavourant is used.
- the carrier that is used in the tablet coating composition may provide for improved gloss and mouthfeel in the final product.
- the powdered flavour composition is combined with the cellulose polymer, the plasticiser, and the sweetener to form the tablet coating composition.
- the tablet coating composition is suitable for coating a tablet to produce a coated tablet that has a pleasant taste and mouthfeel and is easy to swallow.
- the tablet to be coated may contain one or more of any active agent.
- active agents which may be effectively coated are not limited and include pharmaceutically active agents, nutraceutically active agents and veterinarally active agents, such as those typically delivered in a tablet dosage form.

In determining the therapeutically effective amount a number of factors are to be considered including but not limited to, the species of animal, its size, age and general health, the specific condition involved, the severity of the condition, the response of the patient to treatment, the particular compound administered, the mode of administration, the bioavailability of the preparation administered, the dose regime selected, the use of other medications and other relevant circumstances.
- a preferred dosage will be a range from about 0.01 to 300 mg per kilogram of body weight per day.
- a suitable dose can be administered in multiple sub-doses per day.
- Coated tablets of the present invention typically have one or more enhanced properties such as higher gloss, better mouthfeel, good coating adhesion, non- tackiness (slipperiness when wet), being swallowable with little or no accompanying liquid, better taste, and the like. Any of these properties may help people remember that they have taken the tablet, i.e. there is improved compliance. Examples of materials and methods for use with the compositions and methods of the present invention will now be provided. In providing these examples, it is to be understood that the specific nature of the following description is not to limit the generality of the above description.
- Example 1 Formation of a coated tablet having a vanilla flavoured coating
- a tablet coating fluid was formed by combining the following ingredients.
- the tablet coating fluid was then sprayed via a nozzle onto a bed of moving tablets. Typically exhaust temperatures of approximately 40 degrees Celsius are used. Typically a 3-4% coat weight is applied.
- the example tablet composition was as follows:
- Example 2 Formation of a coated tablet having a very sweet berry flavoured coating
- a coated tablet having a berry flavour was formed according to the methods described in Example 1 with a tablet coating fluid formed with the following ingredients.
- Example 3 Formation of a coated tablet having a berry flavoured coating
- a coated tablet having a berry flavour was formed according to the methods described in Example 1 with a tablet coating fluid formed with the following ingredients. This coating has less flavour and is not as sweet as the coating of Example 2.
- Example 4 Formation of a coated tablet having a citrus flavoured coating
- a coated tablet having a citrus flavour was formed according to the methods described in Example 1 with a tablet coating fluid formed with the following ingredients.
