Preclinical assessment of the potential of a 3D chitosan drug delivery system with sodium meloxicam for treating complications following tooth extraction.

Summary of "Preclinical assessment of the potential of a 3D chitosan drug delivery system with sodium meloxicam for treating complications following tooth extraction."

Current medical healthcare has no sufficient innovative drug delivery formulations for treating patients with alveolar osteitis. This study presents a portion of research conducted to design, fabricate, and characterize systems for the treatment of alveolar osteitis. The results demonstrate that intra-alveolar formulations can be designed to function as drug carriers, facilitate wound dressing, and promote tissue regeneration. Our aim was to design cone-shaped implants made of microcrystalline chitosan filled with sodium meloxicam, i.e., a nonsteroidal anti-inflammatory agent. SEM analysis revealed the porous structure and monophasic characteristic of the formulation. Moreover, textural analysis demonstrated the effect of different factors (shape, hydration, addition of an active substance) on the hardness, springiness and cohesiveness of the studied systems. The active substance was released in a two-phase process. In vitro biocompatibility tests performed according to ISO 10993-5 confirmed the lack of cytotoxicity of the tested formulations. The designed formulations did not stimulate human THP1-XBlue™ monocytes to activate the transcription nuclear factor NF-κB, which ensures that the performed systems do not induce local inflammation. These initial results indicate that the innovative sodium meloxicam release system can improve safety and efficacy in clinical settings.

Medical and Biotech [MESH] Definitions

Preclinical testing of drugs in experimental animals or in vitro for their biological and toxic effects and potential clinical applications.

Forms to which substances are incorporated to improve the delivery and the effectiveness of drugs. Drug carriers are used in drug-delivery systems such as the controlled-release technology to prolong in vivo drug actions, decrease drug metabolism, and reduce drug toxicity. Carriers are also used in designs to increase the effectiveness of drug delivery to the target sites of pharmacological actions. Liposomes, albumin microspheres, soluble synthetic polymers, DNA complexes, protein-drug conjugates, and carrier erythrocytes among others have been employed as biodegradable drug carriers.

Systems for the delivery of drugs to target sites of pharmacological actions. Technologies employed include those concerning drug preparation, route of administration, site targeting, metabolism, and toxicity.

Artificial, single or multilaminar vesicles (made from lecithins or other lipids) that are used for the delivery of a variety of biological molecules or molecular complexes to cells, for example, drug delivery and gene transfer. They are also used to study membranes and membrane proteins.

Studies determining the effectiveness or value of processes, personnel, and equipment, or the material on conducting such studies. For drugs and devices, CLINICAL TRIALS AS TOPIC; DRUG EVALUATION; and DRUG EVALUATION, PRECLINICAL are available.
