The invention discloses a preparation method and a formula of an aquatic feed. The preparation method of the aquatic feed comprises the following steps of: S1, selecting the following raw materials in a weight ratio: dry flour of yellow mealworms, dry flour of barley pests, dry flour of black soldier flies, puffed soybean meal, pregelatinized starch, high-gluten flour, spirulina powder, blood worm powder, shrimp shell powder, beer yeast powder, bentonite powder, multivitamin for eels, glycerol monolaurate, choline chloride and calcium dihydrogen phosphate; S2, uniformly stirring the raw materials to form a mixed raw material; S3, adding water into the mixed raw material, continuing stirring, and then puffing the mixed raw material, wherein the water content in the mixed raw material is 17-20% by mass; and S4, after the puffing is completed, cooling and drying the granulated feed formed by puffing. The preparation method and the formula of the aquatic feed are applied to the technical field of aquatic feeds.

The invention discloses acarbose pharmaceutical composition and a preparation method thereof in order to overcome defects that conventional acarbose tablets are prone to moisture absorption, slow to disintegrate, difficult to prepare and the like. The acarbose pharmaceutical composition is prepared from components in parts by weight as follows: 1 part of the acarbose, 1-4 parts of a filling agent, 0.001-0.005 parts of a lubricating agent and 0.005-0.01 parts of a flow aid, wherein the filling agent comprises microcrystalline cellulose and pregelatinized starch. The preparation method comprises steps as follows: the acarbose and the pregelatinized starch with good fluidity are subjected to first-stage mixing, a mixture and the residual filling agent are subjected to second-stage mixing, and finally, the lubricating agent and the flow aid are added for third-stage mixing. The acarbose pharmaceutical composition is free of a disintegrating agent, and a disintegration property of a product is realized by the aid of disintegration performance or a disintegration assistant effect of auxiliary material characteristics of the pregelatinized starch and the microcrystalline cellulose. The requirement for product quality is met with a staged mixing and powder direct-tabletting technology, the technology is simple, and large-scale production is facilitated.

The invention provides a preparation method of domperidone tablets, comprising the following steps: (1) material preparation: performing site-clearing inspection, getting a raw material domperidone, and ingredients lactose G200, pregelatinized starch, low-substituted hydroxypropyl cellulose, povidone K30, lauryl sodium sulfate, silica and magnesium stearate; (2) pelleting: sieving and uniformly mixing raw material and ingredients except povidone K30, silica and magnesium stearate, then slowly adding a povidone K30 solution, uniformly stirring, and sieving to prepare wet particles, drying, sieving and collecting to obtain dry particles; (3) generally blending: respectively adding silica and magnesium stearate into the dry particles obtained in the step (2), to obtain generally mixed particles; and (4) tabletting, and the like. The method is high in production efficiency, and can enable the prepared domperidone tablets to be high in dissolving-out speed and relatively long in expirationdate while ensuring relatively high streptomycin hardness.
