Insights
A new mini-tablet formulation of acetylsalicylic acid (aspirin) offers a better-tasting alternative for children with Kawasaki disease. Pharmacokinetic studies in adults show no significant differences in absorption between the mini-tablet and powder forms, aiding pediatric drug therapy.
Area of Science:
- Pediatric Pharmacology
- Drug Formulation
- Pharmacokinetics
Background:
- Children with Kawasaki disease often receive acetylsalicylic acid (aspirin) powder.
- The powder's bitter taste can lead to poor medication adherence.
- A new mini-tablet formulation aims to improve palatability and compliance.
Purpose of the Study:
- To compare the pharmacokinetic parameters of a novel acetylsalicylic acid mini-tablet formulation against the standard powder form.
- To assess the safety and efficacy of the mini-tablet formulation in a clinical setting.
Main Methods:
- An open-label, crossover study was conducted with six healthy adult participants.
- Participants received both acetylsalicylic acid powder and mini-tablet formulations.
- Blood samples were analyzed to determine pharmacokinetic parameters like Cmax and AUC0-12.
Main Results:
- No statistically significant differences were observed in the pharmacokinetic parameters (Cmax, AUC0-12) for salicylic acid and acetylsalicylic acid between the powder and mini-tablet formulations.
- Adult pharmacokinetic data provides a basis for predicting pediatric responses.
Conclusions:
- The acetylsalicylic acid mini-tablet formulation demonstrates comparable pharmacokinetic profiles to the powder form in adults.
- This formulation has the potential to improve medication adherence in pediatric patients with Kawasaki disease.
- The study contributes to advancing pediatric drug therapy by offering a more palatable option.
Abstract:
Children with Kawasaki disease are prescribed acetylsalicylic acid powder as an antipyretic analgesic and antiplatelet agent; however, some of it remains in the mouth, leading to a bitter or sour taste. To address this issue, an in-hospital mini-tablet formulation of acetylsalicylic acid was developed. In order to use the mini-tablets safely and effectively, dissolution tests alone are not sufficient. Therefore, an open-label crossover study on six healthy participants was conducted to evaluate comparative pharmacokinetic parameters. The pharmacokinetic parameters of salicylic acid were Cmax: 4.80 ± 0.79 mg/L (powder; P), 5.03 ± 0.97 mg/L (mini-tablet; MT), AUC0-12: 18.0 ± 3.03 mg-h/L (P), 18.9 ± 4.59 mg-h/L (MT), those of acetylsalicylic acid Cmax: 0.50 ± 0.20 mg/L (P), 0.41 ± 0.24 mg/L (MT), AUC0-12: 0.71 ± 0.27 mg-h/L (P), 0.61 ± 0.36 mg-h/L (MT), with no significant differences between the mini-tablet and powder formulations. Although pharmacokinetic results obtained from adults cannot be directly applied to children, the results of this study are important for predicting pharmacokinetics. Furthermore, a formulation that can improve medication adherence in children who have difficulty taking acetylsalicylic acid powder, thus contributing to pediatric drug therapy.
