3D Quantitative Co-Mapping of Pulmonary Morphology and Nanoparticle Distribution. Yang, L. et al. (2019).

Inhaled Drug Delivery

Inhaled drug delivery is a crucial route for administering pharmaceuticals, particularly for respiratory conditions like asthma, chronic obstructive pulmonary disease (COPD), and infectious diseases. This route offers several advantages, including rapid onset of action, localized drug delivery to the affected areas of the respiratory system, and reduced systemic side effects. In preclinical research, inhaled drug delivery allows scientists to investigate the efficacy, safety, and pharmacokinetics of novel compounds, as well as to model and explore the mechanisms underlying respiratory disease.

SCIREQ offers turn-key solutions for advancing preclinical research in the field of inhaled drug delivery:

  • The inExpose system enables precise and controlled inhaled drug delivery, allowing researchers to replicate real-world inhalation scenarios accurately. This precision is essential for evaluating the pharmacokinetics and pharmacodynamics of inhaled medications, as well as for assessing their therapeutic efficacy.
  • The flexiVent system synchronizes inhaled dosimetry with ventilation, optimizing drug deposition and distribution in animal models, which is crucial for understanding the therapeutic potential of various drugs and formulations.
  • The expoCube system provides a controlled environment for the exposure of pulmonary tissues in vitro to diverse aerosols, allowing researchers to investigate the effects of different medications and environmental factors on lung tissues.

Reproducible intervention, predictive outcomes

The administration of drugs or novel therapeutic carriers through the lung could be desirable for many reasons. The large surface area and high vascularization of the lung can provide a fast and effective delivery of substances either locally or systemically, via the blood. When considering inhalation as the route for drug delivery, SCIREQ’s intervention platform, the inExpose, offers a significant positive impact on study reproducibility and research efficiency by ensuring process standardization. Integrated with the Aeroneb nebulizer, the inExpose provides sophisticated computer control which enables automated, precise, and repeatable aerosol exposure sessions to small laboratory animals. Furthermore, the inExpose offers small internal volumes, reducing exposure ramp-up times and minimizing the need for large quantities of material.

Inhaled dosimetry

Ventilator Assisted Drug Delivery (VAAD) is a hybrid between nose-only inhalation and intratracheal instillation. The approach consists in intubating the subject and using optimized computer-controlled ventilation profiles to administer the inhaled compound deep into the subject’s lungs, over several breaths. This strategy minimizes subject-to-subject variability, and fosters a highly homogenous aerosol deposition within the lung. It further allows researchers to measure the lung function of the subject prior to and post administration. VAAD can therefore be used for drug delivery and disease modelling (e.g. for IPF studies with Bleomycin).

expoCube with Tray

Reliable and effective in vitro exposure

The expoCube is a novel Air Liquid Interface (ALI)/Transwell in vitro exposure system which permits highly reliable and effective deposition of aerosols onto cells and tissues. This exposure takes advantage of Thermophoresis, which guides small particles and gas onto the target tissue through a temperature gradient and increases the deposition rate from 2% to ~40%.
