In Vitro Drug Dissolution: Compendial Testing Models II01:09

In Vitro Drug Dissolution: Compendial Testing Models II

81
Various dissolution methods are utilized to assess a drug’s dissolution rate, including the flow-through cell, paddle-over-disk, cylinder, and reciprocating disk methods.The flow-through cell apparatus (USP (United States Pharmacopeia) method 4) comprises a reservoir for the dissolution medium and a pump that propels the medium through the cell containing the test sample. This method is crucial for assessing modified-release dosage forms with minimally soluble active ingredients,...

Methods for Studying Drug Absorption: In situ

486
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,...

In Vitro Drug Dissolution: Alternative Methods

84
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...

Methods for Studying Drug Absorption: In vitro

467
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...

Area of Science:

  • Occupational Health and Safety
  • Industrial Hygiene
  • Materials Science

Background:

  • Dermal exposure to volatile organic compounds (VOCs) is a significant occupational health concern.
  • Activated charcoal cloth (ACC) has previously shown potential for assessing dermal VOC exposure.
  • Standardized testing for personal protective equipment (PPE) may not fully represent real-world exposure scenarios.

Purpose of the Study:

  • To evaluate ACC patches as an under-glove indicator for toluene ingress through disposable gloves.
  • To compare ACC-based assessment with standardized chemical permeation testing methods.
  • To investigate toluene ingress under various simulated work-exposure scenarios (vapor, spray, immersion).

Main Methods:

  • ACC patches were placed on a mannequin hand under different glove types (latex, nitrile, neoprene, polymer laminate) within a test chamber.
  • Simulated occupational exposure scenarios included vapor, spray, and immersion.
  • Standard permeation tests using diffusion cells were conducted with glove materials for comparison.

Main Results:

  • ACC testing consistently showed toluene ingress in the order: latex > neoprene > nitrile > Barrier.
  • Standardized testing reversed the order for neoprene and nitrile, indicating higher toluene ingress in nitrile gloves.
  • Discrepancies highlight limitations of standardized methods in replicating real-world glove performance.

Conclusions:

  • ACC patches offer a valuable 'application-style' testing method for assessing dermal exposure to toluene.
  • This approach provides a more realistic evaluation of glove integrity compared to standard permeation tests.
  • Findings emphasize the need for advanced testing strategies beyond traditional methods for occupational hazard assessment.
