RDD Conferences
Respiratory Drug Delivery conferences deliver advanced technical education in pulmonary and nasal drug delivery at live conferences in the US, Europe and Asia, with virtual conferencing introduced in 2020. Conference hallmarks include themed podium sessions on hot topics, a vibrant Poster Session and Exhibition, and business-friendly venues. More Info
Realistic Testing: Polymer VCU Mouth-Throat Models

Realistic throat models can be used in place of the USP throat to provide clinically relevant in vitro testing and improved drug deposition prediction. Featuring internal geometry of the original VCU throats, polymer models are compatible with NGI or ACI connections and available in Small, Medium, and Large.

Realistic Testing: Stainless Steel VCU Mouth-Throat Models

Connect directly to a Pulmoguard filter for convenient Total Lung Dose measurement, and with zero-volume adaptors, they connect to NGI or ACI. Models can be separated into 'mouth' and the 'throat' regions, if desired.

Dosage Unit Sampler Apparatus for MDI and DPI
Dosage Unit Sampling Apparatus (DUSA) for Metered Dose Inhalers (MDIs) and Dry Powder Inhalers (DPIs) are used in inhaler testing to determine the amount of drug emitted from an inhaler. DUSAs from RDD Online are compliant with USP Chapter <601> and EP Chapter <0671> specifications. More Info
Education and Training
On-demand narrated presentations are available 24/7. Each themed module is narrated by Stephen P. Newman and coordinate with the RDD: Essential Theory and Practice textbook. In-built assessments make these suitable for industrial, regulatory and academic training. More Info
Realistic Testing: Nephele Mixing Inlets
Nephele Mixing Inlets allow cascade impactors to operate at constant air flow rates while variable air flows replicating patient inhalation pass through the test inhaler. Combined with a VCU Mouth Throat Model this allows measurement of aerodynamic particle size distributions under simulated patient use conditions. More Info
