A kind of method for preparing coated micropill comprises the steps:
With cinobufacin extract powder, mixing diluents evenly after, add binding agent and place in the extruder, extrudate places spheronizator, behind the round as a ball one-tenth micropill, place fluid bed, temperature 40-60 ℃ condition following drying time of 0.5-4 hour, spray again with coating solution, make coated micropill.
The another kind of method for preparing coated micropill comprises the steps:
With cinobufacin extract powder, mixing diluents evenly after, add binding agent system soft material, cross the 15-20 mesh sieve and granulate, place coating pan, behind the round as a ball one-tenth micropill, the blowing hot-air drying is 0.5-4 hour under temperature 40-60 ℃ condition, sprays with coating solution again, makes coated micropill.
The method that another prepares coated micropill comprises the steps:
Cinobufacin extract powder, diluent are placed centrifugal-fluid bed, with 0.5-2.5m
3/ min blasts air-flow, and mix homogeneously sprays into the solution of binding agent then, makes the micropill of particle size range at 0.5-2.5mm, and gained micropill in ebullated bed under 40-60 ℃ of condition hot air drying 0.5-4 hour sprays into coating solution again, makes coated micropill.
Described binding agent is the aqueous solution or the alcoholic solution of the aqueous solution of the aqueous solution of water, ethanol water, starch slurry, methylcellulose or alcoholic solution, sodium carboxymethyl cellulose or alcoholic solution, polyvinylpyrrolidone.
The described alcoholic solution concentration that is weight percentage is the 60-90% alcoholic solution.
Preparation cinobufacin extract powder is the method preparation of all knowing with those skilled in the art, for example:
Dry maxima skin is cleaned, decocted with water secondary, 45 minutes for the first time, 30 minutes for the second time, collecting decoction filtered, it is 1.1～1.2 that filtrate is concentrated into relative density, and the temperature that relative density is measured is 80 ℃, is cooled to 40 ℃, adding ethanol makes and contains alcohol amount and reach 60%, stir evenly, left standstill 24 hours, get supernatant and reclaim ethanol to there not being the alcohol flavor, adding ethanol makes and contains alcohol amount and reach 85%, stir evenly, left standstill 48 hours, filter, reclaim ethanol to there not being the alcohol flavor, under 80 ℃ of conditions, be condensed into the thick paste that relative density is 1.3-1.6,, pulverize again through the low-temperature reduced-pressure drying, cross 100 mesh sieves, promptly get (Chinese medicine ministry standard WS3-B-2687-97 the 14th).
Coated micropill of the present invention is the spherical shape solid dosage forms of particle diameter between 0.5-2.5mm, divides gastric solubleness coated micropill and enteric coated-pellet, has good fluidity, and medicine stability is good, and can cover the cinobufacin disagreeable taste, promotes the preparation exterior quality; Utilize the coated micropill size of preparation method preparation provided by the invention even, stripping absorbs fast, bioavailability height, instant effect, good looking appearance, preparation technology is simple, and production cost is low, can be loaded on hard capsule or packed, be convenient to store, transport, be convenient to patient again and take, carry.
The only disintegrate in intestinal of enteric-coating material that the inventor filters out from numerous coating materials through a large amount of tests, can avoid the zest of medicine to gastric mucosa, wherein preferred acrylic resin L30D-55, acrylic resin S100, acrylic resin L100, acrylic resin II number, acrylic resin III number, can be in intestinal disintegrate fast, and unexpectedly, the curative effect of cinobufacin also is greatly improved; The gastric solubleness coated micropill extensively distributes equably at gastric, and is wide with the contact area of gastric mucosa, overcome the local irritation of tablet to stomach.The influence of unable to take food things such as the transhipment in gastrointestinal tract, absorption and gastric emptying absorbs rapid-actionly, and infiltration rate is even, and bioavailability among individuals difference is little.
Clinical research confirmation, coated micropill of the present invention, this medicine in the treatment, diseases such as late tumor, chronic hepatitis B have significant curative effect.
The specific embodiment
Other has except the explanation, and the preparation method of cinobufacin extract powder is as follows among the embodiment:
Dry maxima skin is cleaned, decocted with water secondary, 45 minutes for the first time, 30 minutes for the second time, collecting decoction filtered, it is 1.1～1.2 that filtrate is concentrated into relative density, and the temperature that relative density is measured is 80 ℃, is cooled to 40 ℃, adding ethanol makes and contains alcohol amount and reach 60%, stir evenly, left standstill 24 hours, get supernatant and reclaim ethanol to there not being the alcohol flavor, adding ethanol makes and contains alcohol amount and reach 85%, stir evenly, left standstill 48 hours, filter, reclaim ethanol to there not being the alcohol flavor, under 80 ℃ of conditions, be condensed into the thick paste that relative density is 1.3-1.6,, pulverize again through the low-temperature reduced-pressure drying, cross 100 mesh sieves, promptly get (Chinese medicine ministry standard WS3-B-2687-97 the 14th).
