http://howmed.net/pharmacology/absorption-of-drugs/ WebUnder the pKa definition, the lower the pKa, the stronger the acid. This quality is described based on the fact that strong acids completely dissociate in water while weak acids only do so partially, forming a dissociated state (A-) and an undissociated state (AH) that coexist in solution: AH ⇆ A- + H+

They are virtually the same as the fluids inside the body, it can provide a much more accurate picture of how drugs and their formulations are likely to dissolve in vivo. WebThe degree of ionization (pKa) of a drug is a unique physicochemical property that controls its ionization state when in solution. If the drug's p Ka is the same as the pH of the solution it is dissolved in, then 50% of the drug exists ionized and 50% exists nonionized. As the pH of the solution changes, the state of ionization changes as well.
