Poor solubility of APIs is a critical challenge in drug development. One formulation technique to address this challenge is hot melt extrusion (HME). Our Parteck® MXP range of polymers includes two polyvinyl alcohol-based excipients designed for hot melt extrusion to increase solubility and allow for stable and high drug loads for a broad range of APIs.
Parteck® MXP 3-82 Polymer
With a lower degree of hydrolysis along the PVA chain, Parteck® MXP 3-82 polyvinyl alcohol is especially beneficial in forming strong interactions with hydrophobic drug molecules – in the solid state and in solution. Due to this, Parteck® MXP 3-82 excipient has very high capabilities as a precipitation inhibitor and can maintain high levels of supersaturation for physiologically relevant timescales. As a result, Parteck® MXP 3-82 polyvinyl alcohol can provide solubility enhancement for even the most challenging molecules.
Parteck® MXP 4-88 Polymer
With a hydrolysis grade of 88%, Parteck® MXP 4-88 polyvinyl alcohol is more hydrophilic, which provides unique benefits for stabilization of certain molecules in the amorphous form. Furthermore, with a uniquely high thermal application range, Parteck® MXP 4-88 excipient can be utilized for molecules across a broad range of melting temperatures while still providing strong performance, including those classically seen as unsuitable for extrusion due to high melting points.
There’s no such thing as a one-size-fits all formulation, all APIs have individual and specific needs. With our two grades of polyvinyl alcohol for hot melt extrusion, we provide you with the possibility to fine tune your hot melt extrusion formulation to your specific API.
