Step 1: Understand the principle of drug absorption for weak bases. Weakly basic drugs are absorbed most effectively when they are in their unionized (non-polar, lipid-soluble) form, as this form can readily pass through cell membranes. The degree of ionization of a weak base depends on the pH of the environment and its pKa. Step 2: Apply the Henderson-Hasselbalch equation for a weak base. For a weak base (B), the equilibrium is B + H^+ BH^+. The unionized form is B, and the ionized form is BH^+. The Henderson-Hasselbalch equation relating pH, pKa, and the ratio of unionized
