• Example 1 1 H-purine-2,6-dione, 8-[(3R)-3-amino-1 -piperidinyl]-1 -[[4-[[2-[[8-[(3R)-3-amino- 1 -piperidinyl]-7-(2-butynyl)-2,3,6,7-tetrahydro-3-methyl-2,6-dioxo-1 H-purin-1 - yl]methyl]-1 ,4-dihydro-4-methyl-4-quinazolinyl]methyl]-2-quinazolinyl]methyl]- -(2-butynyl)-3,7-dihydro-3-methyl
• NH 4 OH stands for concentrated aqueous ammonia.
• the ratio of the eluent components refer to volume units.
• Copovidone is dissolved in purified water at ambient temperature to produce a granulation liquid.
• a DPP-IV inhibitor (active ingredient), mannitol, pregelatinized starch and corn starch are blended in a suitable mixer, to produce a pre-mix.
• the pre-mix is moistened with the granulation liquid and subsequently granulated e.g. using a high shear mixer.
• the moist granulate is optionally sieved through a suitable sieve (e.g. with a mesh size of 1 .6-3.0 mm).
• the granulate is dried at about 60 °C inlet air temperature in a fluid bed dryer until a loss on drying value of 1 -4 % or 2-4 % is obtained.
• the dried granulate may be sieved through a sieve with a mesh size of 1 .0 mm.
• Magnesium stearate is passed through a sieve for delumping and added to the granulation.
• a final blend is produced by final blending in a suitable blender. The final blend is compressed into tablet cores.
• the tablet cores may be film-coated: Hydroxypropyl methylcellulose, polyethylene glycol, talc, titanium dioxide and iron oxide are suspended in purified water in a suitable mixer at ambient temperature to produce a coating suspension. The tablet cores are coated with the coating suspension to a weight gain of about 3 % to produce film-coated tablets.
• the following tablet compositions can be obtained:
