However, the solubility of Ibu is significantly increased to 3 and 60 mg/ml in phosphate buffer (pH7.4) and ethanol, respectively [76, 77]. The solubility of FITC is 1 mg/ml in PBS (pH 7.4) and 20 mg/ml in ethanol [78,79]. However, the measured value clearly shows that sink conditions are fulfilled during the drug release studies. Additional porous solid dispersions were prepared by increasing the concentration of drug (i.e., 5%, 7.5%, 10%, 12.5% of the total weight of polymer). Hence, COSMO-RS was used to screen suitable IL combinations for the selection of potential ILs. Creative Commons Attribution-NonCommercial 3.0 Unported Licence.

In 1961, Higuchi proposed the first mathematical model to describe drug release from a matrix system.27 For PG-ethanol system, a linear increase in both enthalpy and entropy of solution as a function of PG mole fraction was found. Fetching data from CrossRef. However, the interaction of ibuprofen with various transporters may result in clinically relevant drugdrug interactions. Solubility, the phenomenon of dissolving a solute in solvent to create a homogenous system, is an important parameter to achieve the drug concentration in systemic circulation required for the desired (anticipated) pharmacological response.1 Paracetamol has a solubility of 14,000 mg/L at 25 C[2].

The apparatus was assembled, and the dissolution medium was heated to 37C 0.5C before a drug sample was added to the vessel. The ionic structure with a protonated amine group on an L-valine ester and melting points below 100 C allowed inclusion of these ibuprofen derivatives into the pharmaceutically active protic ionic liquids. The developed ILGELM was applied for the extraction of Ibf. Aqueous solubility is an important parameter for the development of liquid formulations and in the determination of bioavailability of oral dosage forms. Ibuprofen (IB), a nonsteroidal anti-inflammatory drug, is a chiral molecule and is currently used clinically as a racemate (racIB).
