Precision Dosing for In-Vivo & In-Vitro Studies
With its precisely controlled aerosol, PreciseInhale® offers versatility across various exposure modules. Whether sourced from dry powders, inhalers, or nebulized solutions, the aerosol optimization caters to a diverse array of substrates. Serving as an exposure platform, PreciseInhale® facilitates small-scale inhalation experiments, delivering accurate doses for in vivo animal studies, ex vivo lung experiments, and material deposition for in vitro exposure and dissolution testing.
Benefits
- Accuracy in dose delivered to the lungs
- Full PK test with minimal amounts of substance
- Consistency of aerosol generation across different formulations: from aqueous formulations (solutions or suspensions) to dry powders
- Substance delivered to the deep lungs
- Strong de-aggregation capability: possibility to aerosolize APIs without formulation
- Minimization of gastrointestinal exposure: accurate PK curves
