BACKGROUND: In Italy, even though olanzapine has been discouraged for treatment of behaviour disorders in older patients affected by dementia, some physicians chose to prescribe for them. In response to this situation, the Italian Drug Agency (Agenzia Italiana del Farmaco, AIFA) promulgated a cautionary note. MATERIALS AND METHODS: This study examined epidemiological indices for olanzapine prescriptions between 2004 and 2007 in the Marche Region of central Italy and in its provinces, to assess physician compliance with the AIFA note, and to determine whether there were differences in drug prescription between populations of the same territory, or differences based on gender or age group. RESULTS: Our analyses revealed high olanzapine use among young men and mature women, suggesting that these groups are most prone to psychotic symptoms. Analysis revealed that olanzapine prescription in elderly patients was reduced in some provinces, in line with the AIFA note. CONCLUSIONS: Prudent use of olanzapine prescription, in compliance with the AIFA note, was noted throughout the Region. Furthermore, this work offers details that may be useful in future studies of adverse drug reactions.

BACKGROUND: In Italy, even though olanzapine has been discouraged for treatment of behaviour disorders in older patients affected by dementia, some physicians chose to prescribe for them. In response to this situation, the Italian Drug Agency (Agenzia Italiana del Farmaco, AIFA) promulgated a cautionary note. MATERIALS AND METHODS: This study examined epidemiological indices for olanzapine prescriptions between 2004 and 2007 in the Marche Region of central Italy and in its provinces, to assess physician compliance with the AIFA note, and to determine whether there were differences in drug prescription between populations of the same territory, or differences based on gender or age group. RESULTS: Our analyses revealed high olanzapine use among young men and mature women, suggesting that these groups are most prone to psychotic symptoms. Analysis revealed that olanzapine prescription in elderly patients was reduced in some provinces, in line with the AIFA note. CONCLUSIONS: Prudent use of olanzapine prescription, in compliance with the AIFA note, was noted throughout the Region.
