Tablet splitting is a common practice in clinical settings to lower doses, facilitate swallowing or save costs. Splitting devices can be used when hand splitting is difficult or painful. However, data on the accuracy of tablet splitting are limited and it presents a number of patient or formulation-related problems. Thirty nebivolol IR tablets on the Turkish market were split by hand, a tablet cutter (Rabır®) or a knife, and tested for weight variation, loss of mass, disintegration, and friability. The accuracy of split tablets was in the range of 75.4–121, 82.4–115, and 86.9–115% when split by hand, the cutter, and knife, respectively. No significant difference in accuracy was determined between the left and right sides split by the cutter (p = 0.222). The differences were significant for hand and knife splittings (p |
