The aim of this review is to provide a broad perspective on intestinal absorption and the impact of intestinal first-pass metabolism on both clearance and drug-drug interaction prediction along with its historical perspectives. The review also considers abilities to bridge the gap between the increasing amount of intestinal in vitro data and the importance of intestinal first-pass metabolism in vivo. The significance of efflux transporters on the intestinal absorption is also discussed.

Aging is a complex and universal process marked by gradual functional declines at the cellular and tissue levels, often leading to a range of aging-related diseases such as diabetes, cardiovascular diseases, and cancer. Delaying the aging process can help prevent, slow down, and alleviate the severity of these various conditions, enhancing overall health and well-being. Alpha-glucosidase inhibitors (AGIs) are a class of widely used antidiabetic drugs that inhibit alpha-glucosidase in the small intestinal mucosa, delaying carbohydrate absorption and reducing postprandial hyperglycemia.

Establishment of a suitable animal model to evaluate sustained release (SR) formulations is very important because it reduces the development time of SR formulations. Beagle dogs are often used to evaluate prototype formulations since they can be directly administered powder, such as drug substance. However, the physiological condition of dogs is very different to that of humans.

Green tea (Camellia sinensis) is a commonly consumed beverage or dietary supplement. As a natural product with a myriad of proposed health benefits, patients are likely to consume green tea while taking their medications unaware of its potential to interact with drugs and influence drug efficacy and safety. Catechins are the abundant polyphenolic compounds in green tea (e.

Orally targeting nanostrategies of multiple nutraceuticals have attracted increasing attention in ulcerative colitis (UC) therapy for superior patient compliance, cost-effectiveness, and biocompatibility. However, the actual targeting delivery and bioefficacy of nutraceuticals are extremely restricted by their poor solubility, interior gastrointestinal retention, and base permeability. Herein, we developed controllable colon-targeting nanoparticles (NPs) composed of a quaternary ammonium chitosan (HTCC) shell and succinic acid-modified γ-cyclodextrin (SACD) core for precise UC treatment.

This study investigated the effects of on alleviating loperamide-induced constipation. To evaluate the efficacy of in Sprague-Dawley (SD) rats, fecal parameters, the intestinal transit rate, and changes in intestinal mucosal cells were measured through histological analysis. Additionally, serotonin levels, water absorption, tight junction-related gene expression, and the cecal short-chain fatty acid (SCFA) content were analyzed.
