WitrynaConfined liquid impinging jets (CLIJ) were employed in this study to evaluate the feasibility and limitations in the production of nanodrugs (i.e., particle size in the nanorange). Four drugs from different pharmaceutical classes and water solubilities - salbutamol sulfate, mannitol, ibuprofen, and cyclosporine - were examined. Witrynacrystallizer is a design using jet mixers.20-27 In the design, two liquid streams of reactants form narrow, co-planar jets at high velocities impinging upon each other within a small mixing zone. Study on jet mixing as a technique for reactive crystallisation is still limited, in particular for crystallisation of pharmaceuticals.
