Antipsychotics and pituitary tumors: an analysis of the European pharmacovigilance database (EudraVigilance).

One of the possible long-term consequences of antipsychotic-induced hyperprolactinemia is the development of pituitary tumors - prolactinomas. So far, two pharmacovigilance studies of spontaneous adverse event report databases have suggested an increased risk, whereas a longitudinal study carried out with risperidone showed no evidence of increased risk of tumors with mass effect. Besides, information on amisulpride and paliperidone is lacking.

Influence of an inconsistent appearance of antipsychotics on drug adherence in patients with schizophrenia.

In this study, we aimed to determine whether an inconsistent appearance of antipsychotic drugs dispensed was associated with poorer adherence in patients with schizophrenia.To conduct this study, we linked information from different administrative healthcare databases from the Basque Country. Patients with a medication possession ratio (<80%) were considered to be nonadherent.
