[0054] A preparation method of a syrup preparation of desloratadine as described above, said preparation method comprising the steps of:
[0055] (1) Hypromellose is dissolved with an appropriate amount of water to make a certain concentration;
[0056] (2) Desloratadine is dissolved in propylene glycol;
[0057] (3) Dissolve the pH regulator, stabilizer, and preservative with an appropriate amount of water, and then add sucrose to dissolve;
[0058] (4) Slowly add step (2) to step (3) while stirring to make the solution clear, then add the solution of step (1) and flavoring agent, stir evenly, filter and add water to the full amount, and sterilize at 60°C 6 hours.
[0059] The preferred scheme of the present invention is: in the described step:
[0060] In step (1), hypromellose is added with hot water at 70-80°C under stirring, and stirred for several minutes until it is uniformly dispersed, then an appropriate amount of water is added, and stirred to dissolve it;
