bioresorbable polymers platform innovations

Ashland's bioresorbable polymers innovation platform has primary applications in life science. 

Designed for use in the pharmaceutical and medical industries, the platform portfolio contains​

In pharmaceutical applications, formulators typically use these polymers to formulate long-acting injectables (LAI’s) or controlled release systems that are realized in microsphere, nanoparticle, solid implant, in-situ depots, sustained release coatings, long-acting orals (LAO’s) or transdermal microneedle delivery formats. 

In medical device applications, these polymers are used to fabricate degradable devices such as orthopedic screws and plates, vascular grafts, meshes and sutures. In regenerative medicine, these polymers are widely used to create dermal fillers to reduce appearance of lines and wrinkles, and in tissue engineering scaffolds to support cellular and tissue growth.

Bioresorbable polymers are easily broken down or excreted by the body and are designed to support the needs of drug formulation and medical device strategies.

The aim of this study was to develop a hydrophilic oral controlled release system (CRS) using the amorphous form of gliclazide, a BCS class II compound, listed on the WHO list of essential medicines. For this purpose, spray-dried dispersions (SDDs) of gliclazide were produced using various grades of hydroxypropyl methylcellulose acetate succinate (HPMCAS) or copovidone as carrier under fully automated conditions Lu, Zheng, Yonglai Yang, Rae-Ann Covington, Yunxia Vivian Bi, Thomas Dürig, and Reza Fassihi polysaccharides, acetylenics

Hot Melt Extrudates Formulated Using Design Space: One Simple Process for Both Palatability and Dissolution Rate Improvement

This work aimed at obtaining an optimized itraconazole (ITZ) solid oral formulation in terms of palatability and dissolution rate by combining different polymers using hot melt extrusion (HME), according to a simplex centroid mixture design. For this, the polymers Plasdone® (poly(1-vinylpyrrolidone-co-vinyl acetate) [PVP/VA]), Klucel® ELF (2-hydroxypropyl ether cellulose [HPC]), and Soluplus® (SOL, polyvinyl caprolactam-polyvinyl acetate-polyethylene glycol) were processed using a laboratory HME equipment operating without recirculation at constant temperature.

Investigation of the interactions of enteric and hydrophilic polymers to enhance dissolution of griseofulvin following hot melt extrusion processing

Binary, ternary and quaternary dispersions containing GF, enteric polymer (Eudragit L100-55 or AQOAT-LF) and/or vinyl pyrrolidone-based polymer (Plasdone K-12 povidone or S-630 copovidone) were processed by HME.
