Global spread of counterfeit medicines is an imminent threat for the patients' safety. Although major targets of counterfeits are still erectile dysfunction (ED) drugs in the industrialized countries, including Japan, anti-cancer agents and some medicines for metabolic syndromes are also being counterfeited and circulated to the market mainly through the Internet. Due to the global expansion of the business, pharmaceutical companies based in Japan are suffering from the damage of counterfeits, illegal sales including diversion, and thefts, which have never been experienced in the conventional domestic market.

LFDT consist of enteric-coated microgranules (mean particle size, approximately 300 microm) and inactive granules. In the design of the inactive granules, mannitol was used as a basic excipient.

In our previous study, it was clarified that sufficient flexibility of the enteric layer was achieved by the optimized combined ratio of methacrylic acid copolymer dispersion to ethyl acrylate-methyl methacrylate copolymer dispersion and adding the optimized concentration of triethyl citrate to reduce the damage during the compression process. However, since triethyl citrate has an unpleasant bitter taste and is especially incompatible with lansoprazole, it adversely affects the taste and stability of lansoprazole in the enteric-coated microgranules.
View Article and Find Full Text PDFLansoprazole fast-disintegrating tablet (LFDT) is a new patient-friendly formulation of lansoprazole. Since lansoprazole is an antiulcer agent and is unstable under acidic conditions, we have developed LFDT as an orally disintegrating tablet containing enteric-coated microgranules. The effect of compression on dissolution behavior was investigated, as compression affected cleavage and crushing of the enteric layer.
