Preparation and evaluation of QbD based acemetacin loaded transdermal patch formulations for rheumatic diseases.

This research aimed to develop patches for transdermal delivery of acemetacin, which can be used to treat rheumatic diseasesand to determine their potential use. Patches were successfully created by solvent casting method using hydroxypropyl methylcellulose, propylene glycol, polyethylene glycol 400, tween 80, and dimethyl sulfoxide. Prepared patches were found using the Design of Experiments (DoE) method within the Quality by Design (QbD) approach.

Preparation and Evaluation of Poly(lactic acid)/Poly(vinyl alcohol) Nanoparticles Using the Quality by Design Approach.

The aim of the study was to prepare and evaluate the potential use of poly(lactic acid)/poly(vinyl alcohol) (PLA/PVA) nanoparticle formulations as a drug delivery system. The nanoparticle formulations were successfully developed by the double emulsification/solvent evaporation method. The developed formulations were optimized using the quality by design approach of the ICH Q8 (Pharmaceutical Development) guideline.

Critical Tools in Tableting Research: Using Compaction Simulator and Quality by Design (QbD) to Evaluate Lubricants' Effect in Direct Compressible Formulation.

As commonly known, the product development stage is quite complex, requires intensive knowledge, and is time-consuming. The selection of the excipients with the proper functionality and their corresponding levels is critical to drug product performance. The objective of this study was to apply quality by design (QbD) principles for formulation development and to define the desired product quality profile (QTPP) and critical quality attributes (CQA) of a product.

Applying Quality by Design Principles in the Development and Preparation of a New Radiopharmaceutical: Technetium-99m-Imatinib Mesylate.

The clinical impact and accessibility of Tc tracers for cancer diagnosis would be greatly enhanced by the availability of a new, simple, and easy labeling process and radiopharmaceuticals. In this study, Technetium-99m-imatinib mesylate ([Tc]Tc) was developed and prepared as a new radiopharmaceutical for breast cancer diagnosis. The effect of critical process parameters on the product quality and stability of [Tc]Tc was investigated using the quality by design concept of the ICH Q8 (Pharmaceutical Development) guideline.
