PVA for Sustained Release: Theory and Practice


By modifying the drug release characteristics, significant therapeutic benefits can be achieved, such as improved efficacy of the therapeutic agent, reduced adverse effects, optimization of the dosing scheme, and overall improvement in patient compliance. There are numerous approaches for modified release, each with its own benefits and drawbacks. This webinar will present PVA, a fully-synthetic polymer, for optimized sustained release matrix formulations. Combining robust and reliable gel-forming behavior with optimized tableting properties, PVA provides solutions for the most challenging sustained-release formulations.

In this webinar, you will learn:

  • How the gel-formation properties of PVA introduce sustained release
  • Why compatibility with direct compression leads to simplified formulations
  • That PVA can provide flexibility in sustained release formulation development
