Webwhere A-is the ionized drug and HA the unionized drug. For a weak base: pH = pKa + log(B/HB +), where B is the unionized drug and HB + is the ionized drug. Thus, when the local pH is equal to the pKa of the drug, the drug will be 50% ionized and 50% unionized (log 1 = 0). There is further information on this area in the suggested reading.
