In particular, the quality of the split tablets, intended as the uniformity of dosage units (content uniformity and weight variation), was assessed, and the compliance with the limits imposed by the European Pharmacopoeia in the case of whole and split tablets was discussed. Clozapine is well known for its side effects, which include agranulocytosis (with a fatality rate as high as 30 percent), sedation, seizures, sialorrhea, hypotension, weight gain, tachycardia, and hyperthermia.21 A complete blood count must be checked frequently in patients taking this medication.

Formulations such as oral suspensions would allow more precise dose personalization, but to date, they are an unmet need [44]. Introduction. In the absence of specific tests, the quality of sub-divided tablets has been discussed by comparing our results with the European Pharmacopoeia limits indicated on the uniformity of mass of single-dose preparations, the uniformity of the content of single-dose preparations, and the subdivision of tablets [27,28,29]. In the specific case of quetiapine fumarate tablets, the marked weight variation could be correlated to the absence of score lines and the small tablet size.
