Problems solved by technology

[0005] The oral sprays currently on the market can directly act on the affected area, but due to the retention of saliva in the oral cavity, the drugs are diluted and ineffective; some oral sprays are applied to the affected area and can form a film on the affected area to prevent saliva from being taken away Drugs, but the slow-release effect of the drugs is not obvious, and the drugs acting on the affected area are limited, resulting in low utilization of the drugs; in addition, the existing oral sprays need to add a variety of chemical auxiliary agents to make them have a longer shelf life

Embodiment 1

[0030] This embodiment provides a kind of mouth spray preparation, is prepared by weight ratio by following composition:

[0031]

[0032] The preparation method is as follows:

[0033] (1) Dissolving fatty acid choline, glyceryl dioleate and amikacin under the effect of dehydrated alcohol, after dissolving, volatilize dehydrated alcohol to obtain phosphatidylcholine / glyceride dioleate lipid solution;

[0034] (2) Under stirring conditions, the above-mentioned fatty acylcholine / diolein lipid solution containing amikacin is dropped into ultrapure water, and then continue to stir for a period of time;

[0035] (3) The solution in step (2) was sheared at a high speed of 8000r / min for 2min, then subjected to high-pressure homogenization, the homogenization pressure was 200bar, and the homogenization cycle was performed 3 times to obtain drug-loaded liquid crystal nanoparticles;

[0036] c. Dissolve the calcium alginate in water as component X; dissolve the thiolated calcium al...

Abstract

The invention discloses a oral spray preparation and a preparation method thereof. The oral spray preparation is prepared from liquid crystal materials, alginate and mercapto polymer. The preparationmethod of the oral spray preparation comprises the following steps: firstly, dissolving and dispersing a medicine and the liquid crystal materials under an effect of a co-solvent so as to form medicine-carrier liquid crystal nanoparticles; then enveloping the medicine-carrier liquid crystal nanoparticles by adopting the alginate, so that the stability of the medicine-carrier liquid crystal nanoparticles can be greatly improved through the operations, a slow release effect is obvious, and deactivation of the medicine and aggregation and precipitation of the nanoparticles are prevented; the mercapto polymer and half-cystine in a body are combined on an affected part to form a film so as to play isolation and protection effects on the affected part, and therefore, the acting time of the medicine is prolonged, the concentration of the local medicines is obviously increased, development of the medicine is facilitated, the condition that a medicament is diluted due to retention of saliva inan oral cavity so as to lose efficacy is avoided.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to an oral spray preparation and a preparation method thereof. Background technique [0002] The skin tissue in the oral cavity often suffers from various skin injuries, such as ulcers, wounds, burns, etc., which may cause health problems in the body. Studies have shown that skin wound healing is a complex pathophysiological process. During the wound healing process, because the oral cavity is a humid and hot environment, and contains more bacteria, the wound healing process will be prolonged and healing will be difficult. [0003] Chinese patent No. CN105687247A discloses a preparation method of a spray film for the treatment of oral ulcers. Extract cod liver oil and propolis compound homogenate from cod liver to obtain propolis nano-emulsion, supplemented with pearl powder, secretly prepared in an autoclave, and steam sterilized. Thereby the preparation method of the s...
