Abstract:
The aim of this study was to develop a specific simulation program for the validation of a cytotoxic compounding robot, KIRO® Oncology, for the preparation of sterile monoclonal antibodies and anti-infectious drugs. The impact of excipient formulations was clearly measured using simulation accuracy tests with worst case excipient (i.e. viscous, foaming) and allowed to correct the robotic settings prior to real production. Corrections brought accuracies within the acceptable range of ±5%. KIRO® Oncology robot has also the capacity of self-cleaning and a simulation combining media fill test, and environmental monitoring was able to validate the aseptic process including simulation of worst case conditions and highlighting the areas not accessible to self-cleaning to be corrected by additional manual cleaning measures. The risk of chemical contamination was simulated by using fluorescent dye of the process with high-risk excipient formulation and overpressure vials. Quality control reliability was simulated by using a model drug, and final concentration was determined by high-performance liquid chromatography-ultraviolet detection. Finally, productivity was simulated using different models of production showing the impact of the type of drug, the number of vials and the poor standardization of the process.

Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
