Insights

Proton pump inhibitors (PPIs) are increasingly used, but their toxicity risks, especially in children, are not fully understood. Studies link PPI use to infections, nutrient deficiencies, fractures, and rebound acid issues.

Area of Science:

  • Pediatric pharmacology
  • Gastroenterology
  • Drug safety

Background:

  • Proton pump inhibitor (PPI) use is rising globally.
  • The toxicity profile of PPIs, particularly in pediatric populations, requires further investigation.
  • Existing data suggest potential adverse effects associated with PPI therapy.

Purpose of the Study:

  • To review the known and potential toxicity risks of proton pump inhibitors.
  • To highlight the specific concerns regarding PPI use in infants and children.
  • To inform prescribers about the current understanding of PPI-associated risks.

Main Methods:

  • Literature review of studies on proton pump inhibitor use and adverse events.
  • Analysis of reported toxicities in pediatric and adult populations.
  • Synthesis of evidence regarding gastrointestinal, metabolic, and skeletal effects.

Main Results:

  • PPIs are associated with increased risks of gastrointestinal and respiratory infections.
  • Potential adverse effects include vitamin B12 deficiency and hypomagnesaemia.
  • Other reported risks involve bone fractures and rebound hyperacidity upon discontinuation.

Conclusions:

  • The toxicity of proton pump inhibitors is not well-characterized, especially in children.
  • Prescribers must consider the potential risks associated with PPI use in pediatric patients.
  • Further research is needed to fully elucidate the safety profile of PPIs in infants and children.

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Acid Suppressive Drugs for Peptic Ulcer Disease: Proton Pump Inhibitors

Peptic ulcers, often induced by H. pylori infections or NSAID usage, arise from disruptions in the delicate balance of gastric acid production. Peptic ulcers stem from heightened gastric acid levels due to H. pylori infections or NSAID use. The protective mucus layer diminishes in the presence of these factors, allowing gastric acid to erode the stomach lining and form ulcers.
Gastric acid, a potent cocktail of hydrogen and chloride ions, is produced in specialized parietal cells within the...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Acid Suppressive Drugs for Peptic Ulcer Disease: Antacids

In the complex environment of the gastric lumen, excessive acid secretion can lead to the formation or worsening of ulcers within the delicate mucosal layer. Antacids, such as sodium bicarbonate and calcium carbonate, provide relief by neutralizing this acid, transforming it into harmless salt and water. This neutralization process raises the gastric pH from a highly acidic level of 1 to a more basic 3-4, reducing the acidity within the stomach.
However, this neutralization reaction between...

Acid Suppressive Drugs for Peptic Ulcer Disease: Histamine H2-Receptor Antagonists

Histamine H2 receptors, which are intricately located on the basolateral membrane of parietal cells, play a crucial role in modulating gastric acid secretion. When released from enterochromaffin-like cells, histamine engages H2 receptors, initiating the cyclic AMP (cAMP) pathway. In this pathway, adenylyl cyclase converts ATP into cAMP, elevating intracellular cAMP levels. The activation of protein kinase A follows, stimulating the proton pump. This stimulation prompts the secretion of hydrogen...
