Review Article: Advancements in Sustained Release Tablets: Formulation, Mechanisms, and Applications

Sustained release tablets can now be considered as prominent developments in technologies of the drug delivery systems, where issues concerning the variation of drug concentration and regular administration of the medicines are critical. At present, this review aims to discuss factors concerning the formation, operation, and uses of sustained release tablets especially in terms of compliance, longevity of drug effects, and minimum systemic toxicity. These topics include the choice of drugs and polymers, the four classic drug release mechanisms: diffusion, erosion, osmosis, as well as hybrids between them, and the methods to assess the performance. It also identifies trends like the one noted above regarding the use of biodegradable polymers, nanotechnology, and environmentally sustainable processes. There is evidence on clinical effectiveness of sustained release systems but debates are still rife on the governmental aspects and the issues related to implementation of such a large populace. In this review, the author notes that sustained release tablets make a significant difference and remain in the category of drugs that can benefit from further research on soon include temperate advanced formulation and new patient designs. Subsequent studies should also introduce comprehensive investigation between smart polymers and digital components so as to enhance drug delivery and medication compliance for astounding patient outcomes.
