Ranitidine (Zantac ® ) Syrup versus Ranitidine Effervescent Tablets (Zantac ® EFFERdose ® ) in Children Taste Preference Study

gastroesophageal reflux disease and healing of erosive esophagitis in children ≥1 month of age. A low-dose strength of ranitidine is now available in a citrus-flavored 25mg effervescent tablet (dissolved in 5mL of water); this formulation was developed to facilitate use in infants and smaller children. Ranitidine syrup is available in a peppermint-flavored 15 mg/mL formulation. Objective: To compare taste preferences for ranitidine (Zantac®) syrup and ranitidine effervescent tablets dissolved in water (Zantac® EFFERdose®) in healthy children aged 4–8 years and their adult caregivers. Study Design and Methods: A randomized, single-blind, crossover, taste test trial was conducted in 102 children and 102 parents/legal guardians. All subjects received a single 45mg dose of each formulation. After tasting both preparations children were asked: “Now that you have tasted both medicines, which one of these medicines do you think tastes better?” Adults were asked four questions to assess whether they would administer the medication to the children. Results: Seventy-one percent (72/102) of the children preferred the taste of the ranitidine effervescent tablets compared with 29% (30/102) who preferred the syrup (p < 0.001). The majority of adults (71%) responded that they would prefer to administer the effervescent formulation based on taste. Adverse events consistent with product labeling were mild and were reported in four children and three adults: headache (n = 3), drowsiness (n = 1), abdominal pain/cramps (n = 2), and bloating/gas (n = 1). Conclusion: The taste of the ranitidine effervescent formulation dissolved in water is preferred over the ranitidine syrup. Better taste acceptance may facilitate ease of administration and compliance in pediatric patients.
