example 1
[0119] Example 1: Parenteral formulations
[0120] Transfer 250 mL of milliQ water to a suitable glass bottle, then add 50 g of hydroxypropyl beta-cyclodextrin. The mixture was stirred at 500 rpm for 30 minutes, forming a clear solution. Add 556 mg (accurately weighed) of 1-{4-[(1E)-N-{[4-cyclohexyl-3-(trifluoromethyl)benzyl]oxy}ethylimidoyl]-2-ethane benzyl}-3-azetidinecarboxylic acid / fumaric acid (2:1) co-crystal, and the mixture was stirred at 500 rpm for 15 minutes to form a suspension. 305 mg of 2-amino-2-(hydroxymethyl)propane-1,3-diol (Tris, trometamol) was added and the mixture was stirred at 500 rpm for 60 minutes, forming a clear solution with a pH of 7.897. Addition of 250 μl of 1 N NaOH, after stirring at 500 rpm for 2 minutes, resulted in a clear solution with a pH of 7.983. 15 g of mannitol was added and the mixture was stirred at 500 rpm for 15 minutes to form a clear solution. MilliQ water was added to give a clear solution with a pH of 8.015 in a volume of...
