    ABSTRACT: Hyperprolactinemia is an unwanted adverse effect present in several typical and atypical antipsychotics. Aripiprazole is a drug with partial agonist activity at the level of dopamine receptors D2, which may be effective for antipsychotic-induced hyperprolactinemia. Therefore, we analyzed the literature concerning the treatment of antipsychotic-induced hyperprolactinemia with aripiprazole by updating a previous paper written on the same topic. More recent studies were reviewed. They showed that there are two options for the treatment of antipsychotic-induced hyperprolactinemia with aripiprazole. The safest strategy may require the addition of aripiprazole to ongoing treatments, in the case patients had previously responded to antipsychotic drugs and then developed hyperprolactinemia. However, it is advisable to monitor the patients in case relapses and/or side effect, although rare, might occur. Switching drugs should be considered when a patient does not appear to be responding to the previous antipsychotic, thus developing hyperprolactinemia. A cross-taper switch should always be considered, but the risk of a relapse in the disorder may occur more frequently and the patients should be closely monitored. However, limitations must be considered and further studies are needed to definitely elucidate this important issue. Some relevant patents are also described in this review.

    ABSTRACT: Akathisia is a common and potentially debilitating adverse effect of many psychotropic agents. To a physician not specifically screening for this phenomenon, symptoms can appear similar to depression, anxiety, and/or psychosis. Further complicating matters, akathisia may also occur at different points during the treatment period with varying levels of severity in terms of patient distress. Treatment options have been limited by our somewhat poor understanding of akathisia's neurological basis, but dopamine dysregulation is theorized to play a central role. Most pharmacotherapy regimens focus on beta-adrenergic antagonists (eg, propranolol, the current gold-standard), which are thought to affect noradrenergic inputs into the dopamine pathways of the brain. However, new research suggests a role for serotonin-based pharmacotherapy, particularly those affecting 5-HT2a/c receptors (eg, mirtazapine) in regulating dopamine.
