Abstract
AIM
Tablets can be manipulated in several ways to obtain a fraction as the dose-a practice frequently seen in paediatric care due to lack of suitable formulations. Splitting tablets prior to fragment dispersion in a small volume of liquid is one such method. The objective of this study was to investigate the accuracy and precision of this method.
METHODS
Four different types of aspirin tablets (two dispersible, one conventional and one chewing) were split with a tablet splitter into half and quarter fragments. The fragments were dispersed in a medicine measure or an oral syringe. The amount recovered was determined by UHPLC analysis.
RESULTS
The largest quarter fragments ranged from 26.7% to 31.5% of the full tablet weight. Dispersing the fragment in an oral syringe, the amount recovered was greater than 90.8% of the fragment manipulated for all four tablet types, when rinsing was performed. Dispersing the fragment in a medicine measure, the amounts recovered spanned from 32.9% for the conventional tablets to 98.7% for one of the dispersible tablets.
CONCLUSION
Dispersion of half or quarter tablets directly in an oral syringe, but not a medicine measure, could give satisfactory recovery from fragments of all the investigated aspirin tablets.
