Embodiment 1
[0027] Ratio of each raw material:
[0028]
[0029] The preparation process is as follows The preparation process is as follows:
[0030] (1) Measure 1200ml of water for injection, slowly add 80g of chitosan nanoparticles, and stir until dissolved;
[0031] (2) take by weighing sotalol hydrochloride 40g, then add the water for injection of 600ml, stir and make dissolving, by weight to volume, add the activated carbon for needles of 0.15% g / L of the total volume, stir and adsorb for 20 minutes, and ( 1) the middle chitosan nanoparticle solution is mixed;
[0032] (3) Add water for injection to 2000ml, and circulate and filter for 20-30 minutes, decolorize and filter until the feed liquid is clear, adjust the pH value to 5.0 with an appropriate amount of citric acid, and filter with a 0.22 μm filter membrane;
[0033] (4) Spray-dry the finely filtered medicinal liquid obtained in (3) at low temperature to obtain sterile powder, fill it, completely press the stopper, crimp ...
