Definitions
- the present invention refers to a platform for masking the bitter or unpleasant taste of an active ingredient, characterized in that it is a composition in the form of a water-in-oil emulsion, in which the active ingredient with a bitter taste is freely found soluble in the internal phase (aqueous solution), with an external phase composed of oil, for administration to companion animals.
- the pills are considered problematic, especially with regard to administration, due to the difficult swallowing and the chances of not being ingested in their entirety by the animal, which can consume only a part of it.
- palatable chewable compositions known as soft chews, but they are only possible for some drugs and for some species, and they also have a complex and costly manufacturing process, in which several factors must be considered in addition to the final acceptability of the drug, such as the compatibility of the asset and the stability of the palatabiliser.
- a composition in the form of single or multiple emulsion can be applied according to the physical-chemical need of the active or the required release for the drug, in order to obtain the controlled release of a drug, both to protect it from a certain pH, and to maintain the activity of the active ingredient for a prolonged period of time.
- microemulsions and nanoemulsions are similar systems, which also need high concentrations of the surfactant to obtain stability, according to Kale et al.: Emulsion, Micro-emulsion and Nano Emulsion (Sys Rev Pharm. 2017;8(1):39-47).
- a reverse A/O microemulsion for example, can be used to mask the unpleasant taste of a water-soluble drug, where the external phase prevents direct contact of the active substance dissolved in the aqueous phase with the taste buds of the tongue and then the bitter taste of the tongue.
- active after oral administration according to Bhattacharya R. et al. Review on microemulsion-As a potentlal novel drug delivery system. World Journal of Pharmacy and Pharmaceutical Sciences. (2016) 5(6); ISSN 2278-4357.
- its production process is complex and costly, which often makes it unfeasible.
- Patent application PI0211794 describes a pharmaceutically acceptable excipient liquid base that masks the taste, for administration of relatively quantities of unpleasant tasting medications by adding sucralose in an excipient base.
- Patent application PI0012326 describes a liquid composition for oral administration comprising an active ingredient coated with an effective taste masking amount composed of a mixture of a polymer of (a) dimethylaminoethyl methacrylate and neutral methacrylic acid ester (MM/MMAE ) and (b) a cellulose ester, in an aqueous vehicle.
- an effective taste masking amount composed of a mixture of a polymer of (a) dimethylaminoethyl methacrylate and neutral methacrylic acid ester (MM/MMAE ) and (b) a cellulose ester, in an aqueous vehicle.
- the document EP0140225 describes a stable W/O emulsion with unique ability to rapidly dissolve aqueous solutions, obtained by adding water-soluble polymers or copolymers, which has an aqueous phase, a polymeric phase, an inert hydrophobic liquid, one or more emulsifying agents in addition to invert surfactants, without the presence of active ingredients.
- the document WO9302664 deals with stable self-emulsifying (W/O) microemulsions, composed of (i) a lipophilic phase with medium chain fatty acid triglyceride and a low HLB surfactant, (ii) an aqueous-based hydrophilic phase containing a soluble therapeutic agent, and (iii) a high HLB surfactant.
- the present invention provides a platform for masking the bitter or unpleasant taste of an active ingredient, characterized by being a water-in-oil emulsion, in which the active ingredient of bitter taste is freely soluble in the internal phase (solution aqueous), with an external phase composed of oil, which has superior characteristics of palatability and acceptability to animals, and without the addition of sweeteners, for administration to companion animals.
- Figure 1 shows the graph with the percentage of salivation of the animals.
- Figure 2 shows the result of the animals' vomiting craving.
- Figure 3 shows the result of the act of "shaking the head" of the animals.
- Figure 4 shows the percentage of elimination of compositions by animals.
- the present invention is directed to a platform for masking the bitter or unpleasant taste of an active ingredient, characterized by being a water-in-oil emulsion, in which the active ingredient with a bitter taste is freely soluble in the internal phase (aqueous solution), with an external phase composed of oil , with superior characteristics of palatability and acceptability by animals, without the addition of sweeteners, for administration to companion animals.
- composition of the present invention has improved palatability through the development of a water-in-oil (W/O) emulsion, in which an active ingredient was solubilized in water (internal phase), using a polymeric surfactant derived from dimethicone.
- W/O water-in-oil
- This surfactant has the advantage of being efficient at low concentrations, being able to form emulsions by hot or cold processes, and provide superior thermal stability, as well as compatibility with electrolytes and several active ingredients.
- an oil phase known for having low toxicity being liquid at storage temperature (approximately 25°C), and having low molecular weight is used.
- a platform is obtained in the form of a water-in-oil emulsion for masking the bitter or unpleasant taste of an active ingredient, containing a surfactant / solubilizer and a vehicle as an oil phase, in addition of pharmaceutically acceptable excipients.
- compositions of the present invention are preferably selected from those pharmaceutically acceptable and may be selected from, but not restricted to, one or more of the groups consisting of:
- Oil phase carrier agents light and heavy chain mineral oil, vegetable oils and derivatives (eg soy, canola, corn, castor, cotton, peanut, coconut, avocado, olive), esters (eg medium chain triglycerides and long ethyl oleoate, isopropyl myristate, benzyl benzoate, isopropyl palmitate, propylene glycol monocaprylate, Propylene glycol di/monocaprylocaprate, Glyceryl monooleate, Propylene Glycol Caprylate;
- vegetable oils and derivatives eg soy, canola, corn, castor, cotton, peanut, coconut, avocado, olive
- esters eg medium chain triglycerides and long ethyl oleoate, isopropyl myristate, benzyl benzoate, isopropyl palmitate, propylene glycol monocaprylate, Propylene glycol di/monocaprylocaprate, Glyceryl monoole
- Antimicrobial preservatives and/or preservatives methylparaben, propylparaben, benzyl alcohol, parabens, benzalkonium chloride, bronopol, cetrimide, chlorobutanol, phenoxyethanol, imidazolidinyl urea, isothiazolinones, benzoic acid, sorbic acid and derivatives, feruhydroacetic acid;
- Antioxidant and/or reducing agents BHT, BHA, disodium and tetrasodium EDTA, propylgallate, sodium metabisulfite, tocopherols, phenolic acids, acid ascorbic and its derivatives and citric acid.
- composition of the present invention comprises:
- Figures 1 to 4 show the graph with the percentage of the specific reaction observed in cats and, based on the results obtained, it is possible to infer that the animals in groups I and II had very similar reactions in the treatments with the formulation of the invention and the placebo. While animals in group III, treated with the commercially available product, showed more signs incompatible with the palatability of this formulation, which can be evidenced by the frequency and degree of salivation, greater occurrence of vomiting, head shaking and greater elimination of treatment.
- the present invention provides a platform for masking the bitter or unpleasant taste of active ingredients, being useful for administration to companion animals, especially felines.
