Sustained release coating are used in the pharmaceutical industry for the controlled release of medications. Among the most popular applications are cancer drug delivery and brain tumor-specific drug delivery. Currently, tablets are the most popular form of sustained release coatings, accounting for the majority of the market. However, mini-tablets have several advantages over traditional forms, such as low production cost, less inter-subject variability, and reduced dosage dumping. Additionally, mini-tablets are an excellent formulation for modified-release tablets. These products are becoming increasingly popular and will be available in the market soon.

The Global Sustained Release Coating Market is estimated to be valued at US$ 508.2 Mn in 2021 and is expected to exhibit a CAGR of 6.6% over the forecast period (2021-2028). 

While there are many other types of sustained-release coating materials, ethyl & methylcellulose are the most common. The primary mechanism of release is drug diffusion across a water-insoluble membrane. Moreover, this coating material is used in both sustained-release and moisture barrier applications. Additionally, it has taste-masking capabilities. In short, a sustained-release coating offers multiple advantages over conventional formulations.

The development of a new formulation for this type of drug delivery system has also enabled the development of an entirely new form of a pharmaceutical product. In a recent study, a polymer composition comprising a combination of ethyl cellulose and magnesium silicate was developed. These polymers were sprayed into the beads. These particles were coated in a suitable solvent to enhance their release properties. They were successfully tested and approved, and the formulation is suitable for a variety of applications. This new formulation also features pH-insensitive properties, which are desirable for sustained-release drug delivery. Further, it is a promising candidate for the development of sustained-release coatings for oral dosage forms. These coatings induced the release of a model drug, chloramphenicol. The results were impressive, and the study also revealed that ethyl cellulose polymer has a qualitative and quantitative effect on drug release.
