10. Although lidocaine is marketed as its hydrochloride salt, it doesn't exhibit the same level of
physiological activity as the free amine. The free amine is more lipophilic and diffuses across a
neuron cell membrane more rapidly than the ionic salt, resulting in a more rapid onset of
anesthesia. Therefore, sodium bicarbonate (NaHCO3) is added to a solution of lidocaine prior to
injection. How does the addition of sodium bicarbonate promote a faster anesthetic effect?
