Web12 dec. 2014 · Since the dermis is very hydrophilic, hydrophilic drugs would easily pass through it, while lipophilic drugs would experience difficulties in crossing it. Structures, like lymphatic and blood vessels, nerve endings, hair follicles, sebaceous and sweat glands are found in the dermis [ 12 ]. WebMost drugs are weak electrolytes, The ionization of a weak acid HA is given by the equation: pH pKa + log [A - If the concentration of ionized drug [A — ] is equal to concentration of unionized drug [HA], then since log I is 0, under this condition pH = pKa Thus, pKa is numerically equal to the pH at which the drug is 50% ionized.
