Synopsis
Source of validity: Scientific
Rating (out of 5): 4
Acidulants, such as ammonium chloride, are used in clinical practice to help correct metabolic alkalosis—a condition characterized by elevated blood pH due to excess bicarbonate or loss of hydrogen ions. The scientific justification for their use is rooted in their ability to directly increase systemic acidity. For example, ammonium chloride is metabolized in the liver to urea, releasing hydrogen ions, which then combine with bicarbonate in the blood, thereby lowering blood pH toward normal levels. This mechanism is well-documented in medical literature and is referenced in clinical guidelines for the management of severe or refractory metabolic alkalosis, particularly when the underlying cause cannot be easily reversed.
While the use of acidulants is not the first-line treatment for alkalosis—addressing the underlying cause and correcting fluid/electrolyte imbalances are typically prioritized—they remain a scientifically validated option when these measures are not sufficient or feasible. The evidence base includes pharmacological studies, case reports, and recommendations in clinical reference texts. However, due to potential side effects, such as hyperchloremia or worsening renal dysfunction, their use is generally reserved for specific situations under careful medical supervision.
In summary, the use of acidulants for treating alkalosis is scientifically grounded, with a substantial body of evidence supporting their efficacy in selected clinical scenarios, earning a rating of 4 out of 5.
