Accurate estimation of the solubility solid drugs (SDs) in supercritical carbon dioxide (SC-CO2) plays an essential role related technologies. In this study, artificial intelligence models (AIMs) by gene expression programming (GEP) and adaptive neuro-fuzzy inference system (ANFIS) methods were applied to estimate SDs SC-CO2. Hence, a comprehensive database (1816 datasets) comprising operational conditions (T, P) wide ranges (308–348.2 K 80–400 bar), SD's molecular weight (MWSDs), melting point (MPSDs) gathered. Investigation analysis models' strength showed that model developed ANFIS exhibited more satisfactory approximation than GEP model. According optimized model, statistical parameters R2, RMSE, MAE, AARD% obtained, equivalent 0.991, 0.260, 0.167, 13.890% for training 0.990, 0.256, 0.157, 15.273% validation, order. Sensitivity highest effect independent variables on calculating SC-CO2 belong MWSDs, P, MPSDs, T, respectively. Therefore, MWSDs is key factor modeling various Comparing estimated results obtained from AIM with previous semi-empirical AIMs could be accurate

In order to provide the facilities design supercritical fluid (SCF) processes for micro or nanosizing of solid solute compounds such as drugs, it is essential obtain their solubility in green solvents like pressurized CO2. This important role first stage assessing each SCF technology. A statistical method was developed time and employed determine 5-fluorouracil (5-Fu) solubility. The measurements were performed at different pressures (120-270 bar) temperatures (308-338 K) through UV-vis spectrophotometry, time. obtained between 0.0024 0.0176 g/L. 5-Fu mole fraction constant temperature, increases with an increase pressure. Whereas, a crossover point has been seen. Three models approaches applied correlate model experimental data set: (i) seven density-based models, (ii) PR equations state (vdW2 mixing rule), (iii) machine learning-based namely non-linear regressions, Random Forest, Gradient Boosting, Decision Tree, Kernel Ridge. All tested successfully within acceptable accuracy. Meanwhile, empirical suggested by Sodeifian 2, superior lowest AARD% (AARD = 4.12%).

Supercritical anti-solvent (SAS) method is a solvent-free approach where supercritical carbon dioxide (SC-CO2) used as and one can control the output particle size without disturbing nature of particles. The primary objective this study to develop SAS for production Tamsulosin (TML) nanoparticles investigate parameters affecting resultant size. In order optimize nano-sized particles, response surface methodology (RSM) based on Box-Behnken design (BBD (was used. Using dynamic light scattering (DLS) scanning electron microscopy (SEM) analyses, morphologies mean diameter ranges were examined. To look into how process affects TML's chemical physical characteristics, Fourier-transform infrared spectroscopy (FT–IR), X-ray diffraction analysis (XRD) differential calorimetry (DSC) further performed. acquired results demonstrated that pressure imposes largest impact TML production, with exhibiting an inverse correlation pressure. Observations indicated increase in increasing temperature from 35 50 °C. By flow rate drug solution, average exhibited initial decrease followed by trend. Results optimization showed at pressure, temperature, injection 25 MPa, 41.3 °C, 2.9 mL/min, respectively, particles shrink 600 nm.
