Embodiment 1
[0056] A kind of rabeprazole sodium element tablet, comprises the component of following weight portion:
[0057] Rabeprazole sodium 5-15 parts;
[0058] Mannitol 40-80 parts;
[0059] Betaine 1-2.5 parts;
[0060] 5-12 parts of light magnesium oxide;
[0061] Low-substituted hydroxypropyl cellulose 15-40 parts;
[0062] 0.5-1 part of pullulan polysaccharide;
[0063] 4-5.5 parts of calcium hydroxide;
[0064] 10-20 parts of talcum powder;
[0065] 0.5-3 parts of sodium stearyl fumarate.
[0066] Preferably, the granules of rabeprazole sodium, mannitol, betaine, light magnesium oxide, low-substituted hydroxypropyl cellulose, pullulan, calcium hydroxide, talc and hard sodium fumarate The diameter is 60-90 mesh; more preferably 80 mesh.
[0067] In some preferred embodiments, the mass ratio of mannitol to betaine is 30:1.
[0068] In some preferred embodiments, the rabeprazole sodium tablet also includes 4-5.5 parts by weight of meglumine, and more preferably, the mass ...

[0094] Experimental Example 2 Dissolution of Rabeprazole Sodium Tablets
[0095] Get Rabeprazole Sodium Tablets, adopt dissolution assay (Chinese Pharmacopoeia 2010 edition two appendix XC first method) device, with phosphate buffer (pH6.8) (get 0.1mol / L hydrochloric acid solution and 0.2mol / L sodium phosphate solution, mix uniformly according to 3:1, if necessary, use 2mol / L hydrochloric acid solution or 2mol / L sodium hydroxide solution to adjust the pH value to 6.8) 1000mL is used as the solvent, and the speed is 75 revolutions per minute. Operate according to the law. At 45 minutes, take 10 mL of the solution, filter it, take the subsequent filtrate, add phosphate buffer (pH6.8) to dilute to make a solution containing about 10 μg per 1 mL, shake well, and use it as the test solution; Sodium prazole reference substance 10mg, accurately weighed, put in a 100mL measuring bottle, dissolve with water and dilute to the mark, shake up, accurately measure 5mL, put in a 50mL measur...
