Description

  The present invention relates to a granular solid preparation containing a cephalosporin ester and a method for producing the same.

The granular solid preparations such as powders, fine granules, granules and dry syrups can be freely changed in dosage. Therefore, these formulations are important in improving medication compliance for children and / or the elderly. In granular solid preparations that can be easily taken by children and / or the elderly, it is required to suppress unpleasant tastes such as astringency and bitterness of medicinal ingredients (Non-patent Document 1).
In recent years, it has been reported that resistant bacteria of Streptococcus pneumoniae and Haemophilus influenzae are increasing in the pediatric field and the otolaryngology field (Non-Patent Documents 2, 3, and 4).
Based on such current situation, it is predicted that high-dose administration of oral cephalosporin esters such as cefteram pivoxil, cefcapene pivoxil, and cefditoren pivoxil will be essential (Non-patent Documents 4 and 5). .

Cephalosporin esters are β-lactam antibiotics, and for example, cefteram pivoxil, cefcapene pivoxil, cefditoren pivoxil, and the like are known. However, these drugs can have an unpleasant bitter taste. In order to obtain a granular solid preparation that is easy to take a drug having a bitter taste, it is necessary to devise methods such as imparting sweetness and masking the bitter taste.
So far, composite granular solid preparations in which the bitter taste of cefteram pivoxil is reduced are known (Patent Document 1).
