Human Small Intestinal Epithelial Cells Differentiated from Adult Intestinal Stem Cells as a Novel System for Predicting Oral Drug Absorption in Humans

open access: yesDrug Metabolism And Disposition, 2014
Adult intestinal stem cells (ISCs) possess both a long-term proliferation ability and differentiation capability into enterocytes. As a novel in vitro system for the evaluation of drug absorption, we characterized a human small intestinal epithelial cell

Role of gastrointestinal multidrug resistance (MDR1) gene and P-glycoprotein (P-gp) in the oral absorption of methadone in horses [PDF]

open access: yes, 2010
Methadone is a mu-opioid receptor agonist which is a very effective analgesic used to treat moderate to severe acute and chronic pain in humans. Due to methadone’s minimal undesirable side-effects in people, we believed it could be of use in horses as an

Novel Orally Swallowable IntelliCap® Device to Quantify Regional Drug Absorption in Human GI Tract Using Diltiazem as Model Drug

open access: yesAAPS PharmSciTech, 2014
Typically, colonic absorption of a drug is mandatory for a sustained release formulation to hold the drug’s plasma level for more than 12 or 24 h above the minimum therapeutic plasma concentration (efficacy). According to Drugs@FDA, only 7.4% of the oral

How do antimalarial drugs reach their intracellular targets?

open access: yesFrontiers in Pharmacology, 2015
Drugs represent the primary treatment available for human malaria, as caused by Plasmodium spp. Currently approved drugs and antimalarial drug leads generally work against parasite enzymes or activities within infected erythrocytes.

Pharmacometrics Modeling via Physics-Informed Neural Networks: Integrating Time-Variant Absorption Rates and Fractional Calculus for Enhancing Prediction Accuracy [PDF]

open access: yesCMBE 2024 Proceedings Vol. 2
We present a novel method to improve pharmacokinetics modeling, an essential step of drug development. Conventional models frequently fail to fully represent the intricacies of drug absorption and distribution, which limits their predictive abilities required for personalized treatment strategies.
