Dextrorotation oxiracetam orodispersible film made from above-described embodiment 1-3 is subjected to dissolution in vitro experiment, it is molten
Out-degree, which measures, uses slurry processes, measures the dissolution rate of the dextrorotation oxiracetam orodispersible film of embodiment, and dissolution medium is water,
Dissolution volume is 1000mL, and temperature is 37 DEG C, rotating speed 100rpm.As a result it shows：The dextrorotation oxiracetam oral cavity of embodiment 1-3
Disperse film to start to be disintegrated in 10s, drug release is rapid, and the interior dissolutions of 5min dissolve out completely substantially more than 80%, 10min.
Investigate influence of the membrane material to film property
With reference to the preparation method of embodiment 1, with 32 parts of dextrorotation oxiracetams, 47 parts of filmogens, 10 parts of plasticizer (three
Acetin), 10 parts of fillers (pregelatinized starch) and 1 part of corrigent (Aspartame) be that raw material prepares dextrorotation hydroxyl oxygen pyrrole vinegar
Amine orodispersible film.Choose acrylate (Eudragit), pulullan polysaccharide, polyoxyethylene, the polymer such as chitosan be at
Membrane material, and using thickness, elongation, tensile strength and disintegration time as evaluation index, investigate influence of the membrane material to film property.
Eudragit in embodiment: pulullan polysaccharide is mass ratio, such as Eudragit: pulullan polysaccharide (1:1) it is Eudragit: Pu Lu
Blue polysaccharide mass ratio 1:1；Similarly hereinafter.It the results are shown in Table 2.
2 membrane material of table to film property influence (N=6)
As shown in Table 2, using acrylate: the compound film material that pulullan polysaccharide is formed is relative to using chitosan, polyoxy
The dextrorotation oxiracetam orodispersible film that ethylene, acrylate or pulullan polysaccharide are prepared through hot melt extruded has more
Good mechanical performance and shorter disintegration time, dextrorotation oxiracetam orodispersible film prepared by embodiment 8-12 averagely collapse
The time is solved less than 25s, is very suitable for Clinical practice.
Dextrorotation oxiracetam orodispersible film made from above-described embodiment 8-12 is subjected to dissolution in vitro experiment, it is molten
Out-degree, which measures, uses slurry processes, measures the dissolution rate of the dextrorotation oxiracetam orodispersible film of embodiment, and dissolution medium is water,
Dissolution volume is 1000mL, and temperature is 37 DEG C, rotating speed 100rpm.As a result it shows：The dextrorotation oxiracetam mouth of embodiment 8-12
Chamber disperses film and starts to be disintegrated in 10s, and drug release is rapid, and the interior dissolutions of 5min dissolve out completely substantially more than 80%, 10min.Increase
Agent type is moulded to investigate with dosage
Plasticizer is an important factor for influencing film mechanical performance, and dosage can also influence film performance.With reference to embodiment 1
Preparation method, with 34 parts of dextrorotation oxiracetams, 45 parts of filmogens (acrylate EudragitE, pulullan polysaccharide quality
Than 1:4), 10 parts of plasticizer, 10 parts of fillers (pregelatinized starch) and 1 part of corrigent (xylitol) are that raw material prepares dextrorotation hydroxyl oxygen
Pyrrole vinegar amine orodispersible film.Plasticizer is chosen in this experiment：Propylene glycol, glycerine, triethyl citrate, glyceryl triacetate, with
Tensile strength and disintegration time are evaluation index, investigate its influence to film property.The result shows that with glycerine and propylene glycol system
Standby film is easily mutually adhered, and matter is soft, therefore selects glyceryl triacetate or triethyl citrate for film plasticizer.As a result it shows
Show, when glyceryl triacetate and membrane material ratio are less than 1: 12, the demoulding of film is poor；With the increasing of glyceryl triacetate dosage
Add, the tensile strength of film also gradually increases, and disintegration time is in increase trend.To take into account film tensile strength and fater disintegration
Characteristic, it is final to determine that the amount ratio of glyceryl triacetate and membrane material is 1: 6~1: 4.
Filler type and dosage are investigated
Filler can improve the dispersibility of film appearance and dextrorotation oxiracetam orodispersible film, to film mechanicalness
Can also there be certain influence.With reference to the preparation method of embodiment 1, with 30 parts of dextrorotation oxiracetams, 48 parts of filmogen (acrylic acid
Ester EudragitE, pulullan polysaccharide mass ratio 1:2), 10 parts of plasticizer (glyceryl triacetate), 10 parts of fillers and 1 part of flavoring
Agent (Aspartame) is that raw material prepares dextrorotation oxiracetam orodispersible film.This experiment is with mannitol, low substituted hydroxy-propyl
Cellulose, pregelatinized starch, croscarmellose sodium are filler, investigate it to film appearance, thickness and disintegration time
Influence.The result shows that making the film of filler preparation with mannitol, irregular crystal is precipitated in drying process, leads to film
Appearance uniform degree is poor；Sand type is apparent when using croscarmellose sodium as filler, uneven thickness；Using low-substituted hydroxypropyl
The products appearance even uniform of base cellulose, and dextrorotation oxiracetam fine dispersion can be made；Pregelatinized starch can then reduce film
Agent makes film faster disintegration in mouth to the adhesion of tooth and palate.The results show that filler loading is excessive, i.e. solid content
Increase, causes film partially thick, and film easily crimps, flatness is bad, and disintegration time also slows down；Consider from patient using angle,
Film thickness should not be too thin, therefore finally determines that filler and plasticizer consumption ratio are 1: 1~2: 1.
