Insights
Children prefer bottled amoxicillin over phenoxymethylpenicillin, as indicated by prescription data. Early prescription switches suggest lower acceptance of phenoxymethylpenicillin in pediatric patients.
Area of Science:
- Pharmacology
- Pediatric Medicine
- Pharmacoepidemiology
Background:
- Assessing penicillin acceptance in children is crucial for effective treatment.
- Large-scale prescription data can provide insights into treatment adherence and preferences.
Purpose of the Study:
- To determine which penicillin formulation is most widely accepted by children.
- To identify potential taste-related therapeutic failures based on prescription patterns.
Main Methods:
- Utilized the Odense PharmacoEpidemiological Database (OPED) for prescription data from 2009.
- Analyzed penicillin prescriptions issued to children in the Region of Southern Denmark.
- Calculated the rate of early switch (within three days) as a proxy for acceptance.
Main Results:
- Examined 253,018 penicillin prescriptions for 90,054 children.
- Identified 2,599 early switches among Primcillin, Imacillin, and Flemoxin.
- Phenoxymethylpenicillin (Primcillin) showed a 14.7 times higher risk of switch compared to amoxicillin (Imacillin).
Conclusions:
- Phenoxymethylpenicillin demonstrates significantly lower acceptance among children.
- Children exhibit a preference for bottled amoxicillin formulations over phenoxymethylpenicillin.
Introduction:
We wanted to test whether we, by using data on thousands of prescriptions, could answer a prosaic yet very timely question: Which penicillin is most widely accepted?
Material And Methods:
By use of the Odense PharmacoEpidemiological Database (OPED) we extracted data on all penicillin prescriptions issued to children in the Region of Southern Denmark in 2009. We calculated the rate of early switch, defined by redeeming a new penicillin prescription within three days. Such a switch was believed to reflect taste-related therapeutic failure.
Results:
We analysed 253,018 penicillin prescriptions issued to 90,054 children. Among the three analysed penicillin brands, Primcillin (phenoxymethylpenicillin mixture), Imacillin (amoxicillin mixture) and Flemoxin (amoxicillin soluble tablets), we found 2,599 early switches. The relative risk of switch for Primcillin and Flemoxin using Imacillin as reference was 14.7 and 3.3.
Conclusion:
Phenoxymethylpenicillin is less accepted. Children prefer bottled amoxicillin.
