Ethylcellulose-based polymeric effervescent tablet with enhanced moisture resistance
A novel solid polymeric effervescent tablet formulation using ethylcellulose as the primary polymer to protect active pharmaceutical ingredients from moisture-induced degradation. Targets improved shelf life, structural integrity, and chemical stability for pharmaceutical products requiring effervescent delivery.
Overview
This research proposes a novel solid polymeric effervescent tablet formulation in which ethylcellulose serves as the primary polymeric component. The objective is to deliver enhanced moisture resistance, preserving the structural integrity and chemical stability of active pharmaceutical ingredients (APIs) during storage and handling. By mitigating moisture-induced degradation, the formulation aims to extend product shelf life, maintain therapeutic efficacy, and support consistent product quality for pharmaceutical manufacturers and formulators.
The approach addresses a long-standing challenge in effervescent tablet development: the hygroscopic nature of effervescent systems, which can compromise API stability. Ethylcellulose offers a promising solution through its well-known moisture barrier characteristics combined with controlled release and biocompatibility properties.
