Document Type and Number:
WIPO Patent Application WO/2020/251156
Kind Code:
A1
Abstract:
The present invention provides a content carrier for intestinal retention, which is able to further prolong the residence time of contents, such as a drug or lactobacilli, accommodated in the carrier in the intestines, whereby, in the case of a drug, the efficacy of the drug in the intestines may be sufficient, and in the case of lactobacilli, some beneficial bacteria are protected to stay in the intestines without being excreted even during colon cleansing for a colonoscopy, and thus can relieve discomfort of the digestive system or discomfort due to abnormal symptoms of the immune system, which may occur after colonoscopy. The content carrier of the present invention comprises a carrying body which has a size sufficient to be administered orally and a seed-shaped appearance, and has formed therein an accommodation space capable of accommodating contents including a swelling agent. In addition, the carrying body has the same shape and size as those of a melon seed or a watermelon seed, and has, at an end portion at one side thereof, a fish hook-shaped fixing means or an irregular uneven portion.
