Co-polymer Stabilizers for Pressured Metered Dose Inhalers (pMDIs)
A series of novel co polymer surfactants with the general structure LAmEOnLAm were developed along with a Colloidal Probe Microscopy (CPM) method to optimize the surfactant composition using adhesion forces to improve stabilization of drug dispersions. This expands the range of biomolecules and micronized drug particles that can be formulated with pMDIs....
