Drug ionization
WebThe combined effect of ionization and complexation on drug solubility has been derived similarly to this scenario of solubilization by ionization and micellization. The total drug solubility has been derived by different researchers 69–71 by considering the various species in solutions (ie, free unionized drug, ionized drug, unionized drug-ligand … WebSince drug ionization are greatly dependent on the solvent pH, the above partition behavior is often considered as a function of solvent pH, and pKa is often used as a parameter
