Title: Werner M Seidler: Innovator in Pharmaceutical Coatings
Introduction
Werner M Seidler is a notable inventor based in Indianapolis, IN (US). He has made significant contributions to the field of pharmaceutical formulations, holding a total of 3 patents. His work focuses on developing innovative coating technologies that enhance drug delivery systems.
Latest Patents
One of his latest patents is related to film coating formulations. This invention involves aqueous diffusion coating formulations suitable for use on pharmaceutical dosage forms. The formulations comprise an admixture of an insoluble polymer component of a copolymer of ethylacrylate and methylmethacrylate, along with the hydrophilic component, the polysaccharide pullulan. When applied to the substrate of choice, these formulations provide coatings that exhibit good mechanical strength and flexibility.
Another significant patent by Seidler is for a sustained release matrix. This invention provides a matrix composition for sustained drug delivery, which includes an active agent, a hydrophilic polymer, and an enteric polymer. The enteric polymer is impermeable to gastric fluids and aids in retarding drug release in regions of low pH. This allows for lower levels of hydrophilic polymer to be employed. At the pH range of intestinal fluids, this polymer dissolves, increasing the permeability of the dosage form. This approach is particularly useful for sustaining the release of numerous active agents whose solubility declines as the pH increases, a characteristic of weakly basic drugs.
