Nanoform’s platform technology can give failed drug molecules a second chance. The patented technology is based on supercritical CO2. The drug solution is expanded through a controlled process to produce pure drug nanoparticles. The process is more controlled than conventional supercritical technologies, and it produces smaller and more uniformly sized particles. Besides the particle size, also the polymorphism can be controlled. Several active pharmaceutical ingredients have been successfully nanonized using our technology. We have produced particles ranging from 10 nm to 2 µm from both test molecules as well as proprietary APIs.
The reduction of particle size increases the active surface area of API and thus also the dissolution rate and bioavailability of the drug – a feature evident especially with APIs from BCS classes II and IV. The technology is suitable for both chemical and protein-based APIs. Favorable effects in preclinical studies have been shown.
Before and after process
Our nanoparticle production process is robust and reproducible. We can produce stable, pure drug nanoparticles.
Comparison to traditional RESS
Piroxicam microparticles produced with RESS-technology
Piroxicam nanoparticles produced with Nanoform's technology
Stability of Nanonized Particles
The chemical and XRD analysis both show that there is no indication of degradation of any of the processed molecules. The polymorphic purity tests showed that only pure known polymorphs were produced. Moreover, we have tested the stability of nanonized particles using the 10 months' non-accelerated tests and demonstrated that the nanonized particles are stable.
The Dissolution Rates
The dissolution rates of the bulk piroxicam and the nanoparticles in phosphate buffer at pH 6.8 up to 30 min.
