The absorption of ketoconazole has been shown to be impaired in patients with drug-induced achlorhydria. The drug absorption was increased significantly to approximately 65% when the drug was taken with an acidic beverage such as Coca-Cola (pH 2.5). Ketoconazole is a synthetic azole antifungal agent and a weakly dibasic compound with pKa of 2.9 and 6.5. Using the information provided and the pH partition hypothesis, justify the use of Coca-Cola to improve the absorption of this antifungal agent.
