Bioavailability Enhancement: Drug Stability Enhancement and GI Retention

Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...

Modified-Release Drug Delivery Systems: Bioavailability

Modified-release (MR) dosage forms are designed to extend drug release over time, thereby maintaining stable plasma concentrations and reducing dosing frequency. However, their bioavailability is typically below 100% due to incomplete drug release and presystemic metabolism, and limitations in drug permeability across the gastrointestinal epithelium, all of which can restrict the fraction of the drug reaching systemic circulation. Consequently, studying the in vivo bioavailability of MR...

Methods for Studying Drug Absorption: In vitro

In vitro experiments are crucial for understanding the transport and absorption of drugs through biological materials. These studies employ varied methods such as the diffusion cell method, the everted sac technique, and the everted ring technique.
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...
