Insights
Oblong tablets demonstrate comparable acceptability to syrup in children aged 1-5 years. These tablets also show superior swallowability and better palatability, making them a safe alternative to liquid medications.
Area of Science:
- Pediatric Pharmacology
- Drug Formulation Science
- Clinical Pharmacy
Background:
- Pediatric medication administration faces challenges with patient acceptability and adherence.
- Novel drug formulations are crucial for improving therapeutic outcomes in children.
- Mini-tablets have shown promise, but higher-dose requirements necessitate alternative options like oblong tablets.
Purpose of the Study:
- To assess the non-inferiority of oblong tablet acceptability compared to glucose syrup in children aged 1-5 years.
- To evaluate the acceptability, swallowability, and palatability of oblong tablets, mini-tablets, and glucose syrup in pediatric patients.
- To establish oblong tablets as a viable alternative for pediatric drug delivery.
Main Methods:
- An open-label, randomized, two-way cross-over study involving 280 children aged 1-5 years.
- Children were stratified into age groups and randomized to receive either an oblong tablet, glucose syrup, or mini-tablets.
- Acceptability, swallowability, and palatability were assessed using pre-defined criteria and video documentation.
Main Results:
- Non-inferiority in acceptability of oblong tablets versus syrup was demonstrated (84.4% vs. 80.1%).
- Oblong tablets showed superior swallowability compared to syrup (74.5% vs. 53.2%).
- Fewer children experienced unpleasant reactions with oblong tablets (<10%) compared to syrup (up to 40%).
Conclusions:
- Oblong tablets are a safe and promising alternative to liquid formulations for pediatric medication.
- The study supports the use of oblong tablets for improved drug administration in children.
- Oblong tablets offer advantages in swallowability and palatability over traditional syrup formulations.
Objective:
There is limited evidence for the acceptability of various drug formulations holding the potential to improve medicines administration to children. Suitable formulations need to meet the requirements of pediatric patients. Previous studies have demonstrated the acceptance of mini-tablets. Oblong tablets may carry more active ingredient content per unit than mini-tablets and could be an important alternative when the drug substance requires administration of higher doses. The primary objective was to demonstrate non-inferiority of acceptability of oblong tablets in comparison to 3 ml glucose syrup in children aged 1 to 5 years. Secondary objectives were investigation of acceptability, swallowability and palatability of mini-tablets, oblong tablets and glucose syrup in children between 1 and 5 years.
Methods:
An open, randomized, single dose two-way cross-over design in two parallel study arms was applied. 280 children were stratified to one of five age groups and randomized to receiving one oblong tablet (2.5 × 6 mm) in comparison either to 3 ml glucose syrup or to three mini-tablets (2 × 2 mm). Acceptability and swallowability were assessed according to pre-defined evaluation criteria. The application of the formulations was video documented to evaluate the palatability.
Results:
As primary objective, non-inferiority was observed regarding acceptability of the oblong tablet compared to syrup in all age groups (84.4% vs 80.1%, difference 4,29% points with 95% CI of -3.00%,11.57%). For swallowability, superiority of the oblong tablet compared to syrup could be shown (74.5% vs. 53.2%, difference 21.26% points, 95% CI of 11.29%, 31.23%). Regarding palatability, <10% of children demonstrated unpleasant reaction after intake of the oblong tablet or mini-tablets as graded by both raters, however, in contrast up to 40% of children after intake of syrup.
Conclusion:
Oblong tablets are a promising, safe alternative to liquid drug formulations and administration of multiple mini-tablets in children.
