Definitions
- the present invention relates to an oral preparation containing a biguanide drug having an improved feeling of taking
- Biguanide drugs such as metformin are effective for the treatment of non-insulin-dependent diabetes mellitus and the like, and are widely used because of their excellent drug efficacy. At present, tablets are marketed in Japan, Europe, etc., and tablets and solutions are marketed in the United States.
- Biguanides such as metformin have an unpleasant taste such as unique bitterness and irritation as described above. These have made it difficult to develop oral dosage forms other than tablets. Many methods have been proposed so far for blocking or reducing the unpleasant taste of drugs having a bitter taste or the like.
- a method of adding a sweetener or flavoring is known.
- microencapsulation powder coating with a gastric-soluble coating agent, spray drying with a eutectic with a low-melting waxy solid, and
- a method of adding lecithin to the above composition is used.
- simply adding sweeteners and flavors does not improve the unpleasant taste of metformin.
- Other formulations are clearly inferior in terms of ingestibility other than taste, such as high cost due to complicated processes and insufficient effect, and lack of disintegration in the oral cavity, which makes them rough.
- lecithin there is currently no quality raw material available for use as a medical additive.
- a method for containing an oral preparation of metformin containing an organic acid as a bitterness masking agent Japanese Patent Application Laid-Open No. 2000-512293 (corresponding patent: US Pat. No. 6,517,870)) It has been known. This method is effective to some extent when the drug does not disintegrate in the oral cavity at the time of ingestion or the drug is disintegrated or dissolved in the oral cavity when the concentration of metformin is low. In the case of containing, the unpleasant taste cannot be sufficiently masked.
- the problem to be solved by the present invention is to provide a preparation of a biguanide drug which requires a large amount of administration, which has less discomfort such as bitterness and irritation, especially a mushroom preparation which has less discomfort even at a high concentration. It is in.
- the present inventors have found that by using an oral preparation containing an organic acid (or a salt thereof) and sucralose to a biguanide drug, the feeling of ingestion is significantly improved compared to the case of using other sweeteners. That the prepared oral preparation is obtained. Even without using film coating, outer layer formation, inclusion, etc., the formulation can reduce the discomfort such as bitterness and irritation of biguanide drugs and improve the feeling of taking biguanide drugs. I found it to be. As a result of further studies, the present inventors have found an oral preparation that can be easily taken by elderly patients and children and that does not require the ingestion of water when taken, and completed the present invention.
