INTRODUCTION: Little information is available on the pattern of use of antipsychotics in naturalistic conditions in persons initially treated with "conventional" mood stabilizers (lithium and anticonvulsants). METHODS: Data on community prescriptions were extracted from the 2004-2006 claims database of a French health care insurance fund for self-employed workers. Patients included were those continuously exposed to mood stabilizers without concomitant dispensing of antipsychotics over at least a 3-month period. RESULTS: Of the 3 958 persons included, 17.8% had at least one addition/switch to antipsychotics over the follow-up period. The most frequent pattern was addition of second-generation antipsychotics (SGAPs) (41%) or first-generation antipsychotics (FGAPs) (23%) to the mood stabilizer for a relatively short period of time. A switch from mood stabilizer to SGAPs (20%) or FGAPs (15%) was less frequent. Mood stabilizers alone were prescribed again in most patients with the addition of FGAPs (72%) or SGAPs (61%) to mood stabilizers. Conversely, the majority of patients with a switch from mood stabilizers to FGAPs (55%) or SGAPs (58%) went on with these latter treatments over the follow-up. CONCLUSIONS: SGAPs are preferentially prescribed in combination with mood stabilizers and their pattern of use is similar to that of FGAPs. (c) Georg Thieme Verlag KG Stuttgart . New York.
