A post hoc analysis of the risperidone (RIS)/paliperidone (Pali) clinical trials database comprising 64 studies was conducted. Risk of sudden death, cardiovascular (CV), and cerebrovascular events during RIS or Pali treatment was estimated. Treatment emergent CV adverse events were identified using 7 prespecified Standardised MedDRA Queries as follows: embolic/thrombotic events, cerebrovascular disorders, ischemic heart disease, cardiac arrhythmias, cardiac failure, torsades/QT prolongation, and convulsions. Risk in the RIS/Pali pooled group was significantly increased compared to placebo for the following adverse events: syncope, tachycardia, palpitations, edema peripheral, dysarthria, and transient ischemic attack. Incidence of death related to CV events was low and similar across groups. Consistent with the known pharmacologic profile and product information, this analysis of treatment emergent adverse event data from a large, randomized, controlled clinical trials database described increased risk versus placebo for several specific CV events. Apart from events described in existing product labeling, no new safety findings emerged.
