[Effect of Food Thickeners on the Disintegration, Dissolution, and Drug Activity of Rapid Oral-disintegrating Tablets].

For patients with dysphagia in medical facilities and nursing homes, food thickeners are routinely used to aid the ingestion of medicines such as tablets. However, some types of thickeners affect the disintegration and dissolution of tablets, such as rapidly-disintegrating magnesium oxide tablets and donepezil hydrochloride orally disintegrating tablets. Additionally, delayed disintegration and dissolution of tablets affect a drug's efficacy. As an example, with Voglibose orally disintegrating tablets, marked differences are observed in changes in glucose levels during glucose tolerance testing. When using food thickeners to aid tablet ingestion, it is therefore necessary to select a product that has little effect on drug disintegration, dissolution, and activity.
