Controlled Release of Bi-Layered Malvidin Tablets Using 3D Printing Techniques

Malvidin belongs to the class of anthocyanidin, a pigment compound present in fruits and vegetables like the colored berries, flowers, and vegetables which have pigments on it and it is available commercially as malvidin chloride. Malvidin is known to possess many medicinal characteristics like anti-microbial, anti-diabetic, anti-inflammatory, anti-obesity, and anti-cancer. In this research paper, a 3D printing technique is used which evolves a 3D printer based on desktop that extrudes tablets comprising the active drug which here is malvidin our main ingredient and the other excipients which are used as binders and disintegrants. Methods which are adapted here for the formulation of 3D printed tablet make the tablets appropriate for immediate and sustained release with its definite physical and mechanical properties like hardness, friability, and weight. Tablets that are extruded by the 3D printer are controlled release bi-layer tablets. Due to involvement of 3D printer, printing cost for the bi-layered tablets found very low that makes our method as cost efficient.
