Description
Technical field
The invention belongs to oral solid formulation field, and in particular to a kind of patient of suitable dysphagia takes, and does not have
Taste masking coated preparation of bitter taste and preparation method thereof.
Background technology
Oral administration is the most frequently used administering mode, the advantage is that drug safety, conveniently, easily receives and adopt for patient
With disadvantage is however that absorption is slower, general oral half an hour is just effective, and is easily destroyed by intestines and stomach, has to intestines and stomach strongly
Stimulate or have bad smell or the medicine for the treatment of concentration is not suitable for being prepared into mouth needed for can not reaching in intestines and stomach absorption difference
Formulation.Wherein oral formulations include the formulations such as tablet, capsule, granule, oral liquid, have been swallowed for children, old man etc.
Difficult patient, preceding 2 and improper.
Research shows, dysphagia be not only refer to the autonomous swallow such as children, old man not yet develop completely/move back
The crowd of change, in addition to may temporary caused by congenital development imperfection, disease, physical damnification etc. or chronicity gulp down
Pharynx is difficult, for example, the imperfection that a minority is developed due to belch, causes when swallowing, medicine is easily accessible tracheae rather than oesophagus,
Also it is one kind of dysphagia.
Compared to liquid dosage forms such as oral liquids, granule (including granula subtilis), dry suspensoid agent etc. are used as non-aqueous solid system
Agent, the conventional substitute products of piece agent, capsule etc. are prepared, there is its unique advantage, such as to prepare cost cheap, easily stored
Carry etc..At present, for the patient of dysphagia, 2 kinds nothing more than of such oral solid formulation is taken, that is, is dissolved in point
Take after dissipating/dissolving, or directly swallow, however, which kind of mode no matter taken, because such preparation specific surface area is (relative to piece
The solid pharmaceutical preparations such as agent) increase, easily exposure medicine bad smell, made troubles to taking.In addition, investigation display, relatively
Mode is taken in former, many patients are more willing to directly swallow such preparation, rather than are taken after adding water dispersed/dissolved,
This is probably directly to take more convenient, and the bad smell of preparation is smaller.Also, particularly closed for unconscious crisis patient
It is suitable.
However, the non-aqueous solid pharmaceutical preparation prepared using prior art, is directly swallowed existing greatest problem and is, particle
Or particulate can produce certain astringent sense in mouth, the time for causing preparation to rest in mouth increases rather than quickly entered esophagus.Lose
Regret, this shortcoming, for dysphagia patients, further amplification.
Further, since most drug has the bad smells such as bitter taste, excitant, not relaxing for patient is brought when directly swallowing
Taking sensation can allow it to limit the application of such preparation significantly, therefore, taste masking is also directly to swallow system to taking generation mental handicape
One of problem that agent must solve.
Coating method is the most frequently used masking methods of solid pharmaceutical preparation, and coating refers to using Utech (Eudragit), ethyl cellulose

Or particle) be coated, reach the purpose of taste masking, including 3 kinds of film-coating, enteric coating and sugar-coat.Can be reduced after coating medicine with
The contact of taste bud, so as to taste masking.Protection against the tide, lucifuge, isolation air, raising medicine stability and control medicine can also be played simultaneously
Thing rate of release and the effect at position.
Coating material ethyl cellulose (EC), hydroxypropyl methyl cellulose (HPMC) clothing film are not influenceed by pH, in vivo respectively
Discharged in kind of environment in certain speed, for bitter taste than stronger medicine, taste masking clothing film can reach taste masking function but very
Difficulty makes medicine quick and completely discharged.WO1999/026608 provides a kind of coated granule of granulated crystalline ibuprofen, and it is adopted
With directly by the mode of drug coating, by insoluble polymer ethyl cellulose, the hydrophilic polymer of certain weight ratio
The coating membrane of hydroxypropyl methylcellulose and silica composition is coated on the drug core with certain particle diameter in water-alcohol dispersion liquid
On, make up to taste masking, stable ibuprofen granule.But employ the ethyl cellulose of water-insoluble, its discharge still by
Influence is arrived.
Utech dissolves in acid, is swelled in water and neutrality, alkaline environment, although overcoming ethyl to a certain extent
The shortcomings that cellulose, but influenceed by vivo environment excessive, and excessively rely on gastric acid environment.When different crowd is taken medicine
When, the difference of gastric acid environment also influences whether the release of medicine.
For bitter taste than more serious insoluble drug, how while excellent taste masking effect is provided, can protect again
The quick release of medicine is demonstrate,proved, ensures the validity of medicine, turns into a urgent problem to be solved in the prior art.
