Embodiment 1

[0088] The formula for making 1000 capsules is as follows:

[0089]

[0090] Preparation Process:

[0091] 1) Take the prescribed amount of levocetirizine hydrochloride and microcrystalline cellulose, pass through an 80-mesh sieve, and use 8% gelatin solution as a binder, extrude and spheronize, prepare 20-30-mesh pellets, and dry at 50±5°C When the water content is less than 3%, levocetirizine hydrochloride gastric-soluble pellets are obtained;

[0092] 2) Mix montelukast sodium and micropowder silica gel evenly in the prescribed amount, use 8% hydroxypropyl cellulose solution as a binder, and sucrose round pellets to obtain montelukast sodium pellets. Dissolve methacrylic acid copolymer type C, talcum powder, and triethyl citrate in sodium hydroxide aqueous solution, enteric-coated to increase the weight by 15%, and dry to less than 3% moisture to obtain montelukast sodium enteric-coated pellets ;

[0093] 3) Calculate the filling amount of levocetirizine hydrochloride ...
