WebWhen a weakly acidic or basic drug is administered to the body, the drug will ionise to a greater or lesser extent depending on its piCa and the pH of the body fluid in which it is dissolved. The pH of the body varies widely, but the most important biological solution is the blood, which, as stated above, normally has a pH of 7.4. 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.
