WebHistamine is an organic nitrogenous compound involved in local immune responses, as well as regulating physiological functions in the gut and acting as a neurotransmitter for the brain, spinal cord, and uterus. Since histamine was discovered in 1910, it has been considered a local hormone because it lacks the classic endocrine glands to secrete it; however, in … WebFor a weak acid: pH = pKa + log (A - /HA), where 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).
