Patent Application
20230277440
The invention relates to an oral preparation for medicine, food and healthcare product, specifically to an effervescent gel dry powder preparation and preparation method thereof.
Oral preparations generally include tablets, capsules, suspensions, granules, solutions, syrups and gels. For infants and some patients with special swallowing reflex dysfunction, due to their age, physical or disease reasons, their swallowing reflex is impaired, and during the swallowing process, it is easy to aspirate liquid or solid oral substances into the trachea, resulting in aspiration pneumonia or asphyxia or even death. Therefore, the most suitable oral dosage form for him/her is a gel with a certain viscosity and adjustable viscosity. A certain viscosity can make the gel adhere to the mucous membrane of the mouth and pharynx, so that it can only enter the esophagus through swallowing and prevent accidental aspiration into the trachea; a certain consistency can make the gel form a larger block and reduce its mobility, which is easy to swallow and can prevent the oral substance from flowing into the trachea due to the gravity of body position.
according to the different severity of the patient dysfunction, different eating habits, the different patient are met by the gel remove different viscosities. At present, there are few gels in the market, the viscosity is fixed, it is not adjustable, in the preparation process, it needs to add preservative, and it needs to be stored at low temperature.
Due to the defect of the current market gel, it can not meet the requirement of infant and some patient reflex dysfunction, and the current gel is not freshly prepared, the taste is bad, and it is not easy to obtain wide application.
The technical problem to be solved by the invention is to provide a new type oral effervescent gel with adjustable viscosity. The invention can meet the requirements of infants and some patient oral medicine and food with function of swallowing and reflecting functional disorder.
In order to realize the technical effect, the present invention provides an effervescent gel dry powder preparation, the effervescent gel dry powder preparation comprises one of pharmaceutical ingredient or active ingredient, gel particle, agent and auxiliary filler; the said gel the weight percentage of the quick-swelling gel in the effervescent gel dry powder preparation is 5% to 15%; and the weight percentage of the effervescent agent gel is not less than ⅕ of the weight percentage of the gel dry powder preparation of the effervescent gel.
In one embodiment, the pharmaceutical ingredient is cephalosporin medicine, macrolide medicine, ribavirin, oseltamivir, fumaric acid, ibuprofen, acetaminophen, vitamin medicine, dextromethorphan hydrobromide or Chinese patent medicine particles.
In one embodiment, the pharmaceutical ingredient is 1% to 50% of the weight percentage of the effervescent gel dry powder preparation.
In one embodiment, the active ingredient is Lactobacillus acidophilus, AKK, Bifidobacterium, Lactobacillus rhamnosus, Clostridium butyricum, Saccharomyces cerevisiae, Enterococcus, Bacillus licheniformis or Bacillus cereus.
In one embodiment, the gel particle card is BmM971P uniformly adhered to the polyethylene glycol 6000 wax particle surface to form a compact particulate matter
In one embodiment, the bubble agent sodium bicarbonate, the bubble is agent % to 5% of the weight percentage of the effervescent gel dry powder preparation.
In one embodiment, the auxiliary filler comprises flavouring agent, taste agent and agent, the flavouring agent accounts for 40% to 90% of the weight percentage of the effervescent gel dry powder preparation; the taste masking agent accounts for 0% to 10% of the weight percentage of the effervescent gel dry powder preparation; the weight percentage of the coloring is agent % to 6% of the effervescent gel dry powder preparation.
Another aspect of the present invention is to provide an effervescent gel dry powder pre-adjusting agent, the effervescent gel dry powder pre-adjusting agent for mixing with other granular preparation to prepare effervescent gel preparation, the effervescent gel dry powder pre-adjusting agent comprises gel agent and the weight percentage of the effervescing agent gel not less than ⅕ of the weight percentage of the gel dry powder pre-adjusting agent of the effervescent tablet gel the particle card of the gel the Bum 971P, which is uniformly adhered on the surface of the wax particle of the polyethylene glycol 6000 to form a compact particulate matter The bubble-making agent is sodium bicarbonate the gel particle diameter is particulate matter-250 microns, and because of the large amount of carboxyl of the carbomer or the carbophil; It reacts with sodium bicarbonate in the sodium bicarbonate solution to produce water and carbon dioxide gas, at the same time, the carbomer will become thick to form gel in the alkaline solution. Therefore, the quick-expansion gel of the present invention and the bubble agent mixture can quickly form bubbles gel mixing with water, at the same time, the drug or active substance is wrapped.
