  33. Slide 33: Local Anesthetics Exist in a Balance Between Water- and Lipid-Soluble Forms

    Local Anesthetics Exist in a Balance Between Water-Soluble and Lipid-Soluble Forms • Local anesthetics have pKa values > 7.4, so at normal physiologic pH of 7.4, the majority of molecules exist as the water-soluble quaternary salt not able to penetrate nerve cell membrane Water-Soluble Ionized Form

  34. Slide 34: Local Anesthetics Exist in a Balance Between Water- and Lipid-Soluble Forms

    Local Anesthetics Exist in a Balance Between Water-Soluble and Lipid-Soluble Forms • The acidic environment associated with inflammation shifts the balance further to the left, resulting in far less drug penetrating the nerve membrane and reduced anesthetic effects. • With a pKa of 8.1, bupivacaine
