The Feasibility of the Repeated Administration of Acetylsalicylic Acid Mini-Tablets to Children with Kawasaki Disease: A Pilot Study.

: Mini-tablets are a novel pediatric dosage form designed to mask drug taste and facilitate easier administration. This study aimed to assess the feasibility and acceptability of uncoated acetylsalicylic acid (ASA) mini-tablets in Japanese children with Kawasaki disease (KD) aged 1 to 4 years. : A retrospective case series study of three pediatric patients with KD treated with ASA mini-tablets (3 mm diameter, 10 mg) was conducted at Showa University Hospital. ASA mini-tablets were administered for up to 68 days. Caregivers recorded daily medication intake and any issues in medication logbooks. : All three patients successfully took 100% of the prescribed doses. No adverse events related to mini-tablet ingestion were reported. Patients could take the mini-tablets for extended periods (63-68 days) as part of their KD treatment. : ASA mini-tablets showed potential acceptability in this small cohort of pediatric patients with KD. This study represents the first investigation into the acceptability of mini-tablets containing active ingredients in Japanese pediatric patients. Larger studies are needed to confirm these findings and evaluate long-term safety and efficacy.
