Area of Science:
- Pharmaceutical Sciences
- Drug Delivery Systems
- Clinical Pharmacology
Background:
- Increasing number of new drugs exhibit challenging pharmaceutical (e.g., solubility) and biopharmaceutical (e.g., permeability) properties.
- Pharmaceutical companies increasingly rely on human absorption studies for drug development guidance.
- Early clinical development necessitates efficient and non-invasive methods for drug administration.
Purpose of the Study:
- To introduce and evaluate the Enterion capsule as a novel tool for drug delivery in human absorption studies.
- To demonstrate the capsule's capability in delivering various drug formulations to specific gastrointestinal sites.
- To facilitate early-stage clinical development of drugs with challenging properties.
Main Methods:
- Utilized engineering-based capsules for non-invasive drug delivery within the human gut.
- Employed the Enterion capsule for targeted delivery of diverse drug formulations (solution, powder, granulate).
- Conducted human absorption studies to assess drug delivery efficiency and site-specificity.
Main Results:
- The Enterion capsule successfully delivered various drug formulations to targeted regions of the human gut.
- Demonstrated ease and efficiency in drug delivery across different formulation types.
- Provided a viable 'route map' for the development of drugs with challenging properties.

01:16Methods 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...

01:09Methods for Studying Drug Absorption: In situ
In situ experiments, such as the Doluisio method and Single-Pass Perfusion technique, provide critical insights into drug uptake by simulating in vivo conditions for drug absorption.
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...

01:27Bioavailability Enhancement: Drug Permeability Enhancement
After oral administration, poor permeability often limits the rate at which drugs are absorbed through the intestinal epithelium. Enhancing drug permeability is crucial for effective therapy, and several strategies have been developed to overcome this challenge.One effective strategy involves the use of lipid-based formulations. These formulations enhance dissolution and solubility, targeting physiological mechanisms to increase drug absorption. This includes stimulating bile salt secretion,...
01:17In Vitro Drug Dissolution: Alternative Methods
Alternative drug dissolution methods include the rotating bottle, intrinsic dissolution test, peristalsis, and the Franz diffusion cell method. The rotating bottle method involves meticulously rotating tightly capped controlled-release beads in a temperature-controlled bath. Periodic decanting of samples allows for residue assay, followed by refilling with fresh medium and testing at various pH levels to emulate the gastrointestinal tract conditions.In contrast, the intrinsic dissolution test...
01:18Formulation and Manufacturing Process: Physical Attributes of Generic Tablets and Capsules
Bioequivalence in generic drugs, such as tablets and capsules, refers to their pharmaceutical equivalence to the brand-name counterparts. However, for therapeutic equivalence, manufacturers must also consider physical attributes like size, shape, and weight (FDA Guidance for Industry, December 2003). Discrepancies in these aspects could impact patient compliance and cause medication errors. For instance, swallowing difficulties, often experienced with larger tablets or capsules, can lead to...
01:24Modified-Release Drug Delivery Systems: Site-Targeted
Site-targeted drug delivery systems enhance therapeutic efficacy while minimizing systemic toxicity and treatment costs. Unlike conventional methods, these systems ensure precise drug delivery, improving bioavailability and reducing side effects. Targeted drug delivery is classified into three levels. First-order targeting directs drugs to the capillary beds of specific organs or tissues. Second-order targets specific cell types, such as tumor cells, using receptor-mediated interactions.
