[0002] Multilayer sustained-release tablets are tablets with a special structure composed of drug layers with different release rates. This allows for timed and quantitative drug release, improving therapeutic efficacy and reducing adverse reactions. In the production of multilayer sustained-release tablets, layer pressing is a key process. Different materials are layered and filled into a mold, and then pressed layer by layer to ensure strong bonding between layers and uniform drug content.
