Insights
Children preferred strawberry-flavored carbocysteine oral solution over mint. This study used a facial action coding system to assess palatability in pediatric patients, finding strawberry taste more appealing.
Area of Science:
- Pediatric Pharmacology
- Sensory Science
- Clinical Trial Design
Background:
- Palatability of liquid medications is crucial for pediatric adherence.
- Carbocysteine oral solutions are commonly prescribed for respiratory conditions.
- Objective taste and preference data are needed to optimize pediatric formulations.
Purpose of the Study:
- To compare the palatability of strawberry versus mint flavored carbocysteine oral solutions.
- To evaluate the effectiveness of a facial action coding system for palatability assessment in children.
- To determine children's taste preferences for pediatric pharmaceutical products.
Main Methods:
- A randomized, triple-blind, crossover trial involving 42 healthy children aged 2-12 years.
- Palatability assessed using the FaceReader™ facial action coding system for emotional valence.
- Face-to-face interviews and taste preference rates collected for older children (5-12 years).
Main Results:
- Strawberry-flavored carbocysteine showed significantly higher emotional valence scores compared to mint.
- 69% of participants exhibited higher emotional valences for the strawberry preparation.
- 88.5% of children aged 5+ preferred the strawberry taste, with 77.8% choosing it for re-administration.
Conclusions:
- Strawberry-flavored carbocysteine oral solution is more palatable and better accepted by children.
- The facial action coding system offers a viable, objective method for assessing pediatric product palatability.
- Flavor optimization is key to improving medication adherence in pediatric populations.
Abstract:
Objective: To compare and evaluate the palatability of two carbocysteine oral solutions (strawberry vs. mint taste) among healthy children aged 2-12 years. Methods: A randomized, triple-blind, crossover, palatability trial in 42 children aged 2-12 years. All subjects received two preparations of carbocysteine oral solutions (strawberry vs. mint) according to randomized administration sequences, and the administration process was recorded by video. The palatability assessed by emotional valences was performed using a facial action coding system by FaceReader™, which reflected the quantification degree of emotion; a positive value represents positive emotion, and a negative value represents negative emotion. At the same time, a face-to-face interview was conducted for 5- to 12-year-old participants. Then, the taste preferential rates were compared to assess the palatability of two carbocysteine oral solutions. Results: Forty-two children were enrolled in this study. Twenty children first tasted the carbocysteine oral solution mint taste and then the strawberry taste preparation (M-S sequence), while 22 children tasted the strawberry preparation first and then the mint one (S-M sequence). The emotional valence of mint preparation (-0.9 in M-S and -1.2 in S-M) was both relatively lower than that of strawberry taste (both -0.7 in M-S and S-M) in two sequences; 69.0% (29/42) of participants' emotional valences for strawberry preparation were higher than those for mint preparation. Among 27 participants aged ≥5 years, the taste preference rate was 88.5% (23/26) for the strawberry preparation (one missing value for the taste preference), and 77.8% of participants (21/27) chose the strawberry preparation if they had to take the medicine one more time. Conclusion: The carbocysteine oral solution with strawberry taste is an appealing preparation since it was better received by children. The facial action coding system could be an effective alternative for palatability assessment of pediatric pharmaceutical products.
