They make it hard for someone to think clearly, make good judgments, respond emotionally, communicate effectively, understand reality, and behave appropriately. Assessment of the relationship between atypical antipsychotic use and glucose abnormalities is complicated by the possibility of an increased background risk of diabetes mellitus in patients with schizophrenia and the increasing incidence of diabetes mellitus in the general population. Given these confounders, the relationship between atypical antipsychotic use and hyperglycemia-related adverse events is not completely understood. However, epidemiological studies suggest an increased risk of treatment-emergent hyperglycemia-related adverse events in patients treated with the atypical antipsychotics. Precise risk estimates for hyperglycemia-related adverse events in patients treated with atypical antipsychotics are not available.
Extensively metabolized, principally in the liver via CYP2D6, to an active metabolite 9-hydroxyrisperidone; N-dealkylation is minor metabolic pathway. Monitoring of orthostatic vital signs should be considered in patients for whom this is of concern. Who should not take Risperdal?

No dosage adjustment is recommended based on race. No differences in pharmacokinetics were observed in a pharmacokinetic study conducted in Japanese and Caucasians. Further, because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. An examination of population subgroups did not reveal any evidence of differential responsiveness on the basis of gender, age, or geographic region. There were insufficient data to explore differential effects based on race.

In general, recommended dosing for elderly patients with normal renal function is the same as for younger adult patients with normal renal function. In patients with hepatic impairment, pharmacokinetics were similar to those in young healthy adults; however, the mean free-fraction of risperidone in plasma was increased by about 35% due to diminished albumin and α 1-acid glycoprotein concentrations. 1 Dosage adjustment recommended. 1 See Special Populations under Dosage and Administration.

Paliperidone is a centrally active dopamine Type 2 D 2 antagonist and with predominant serotonin Type 2 5HT 2A activity. Paliperidone is also active as an antagonist at α 1 and α 2 adrenergic receptors and H 1 histaminergic receptors, which may explain some of the other effects of the drug. Paliperidone has no affinity for cholinergic muscarinic or β 1- and β 2-adrenergic receptors. Elderly patients exhibit a greater tendency to orthostatic hypotension, careful titration with monitoring of orthostatic vital signs should be considered.

In a study of once-daily dosing, efficacy of 8-mg dosage generally was better than for 4-mg dosage. Efficacy was evaluated using two assessment scales: the Aberrant Behavior Checklist ABC and the Clinical Global Impression - Change CGI-C scale. The primary outcome measure in both trials was the change from baseline to endpoint in the Irritability subscale of the ABC ABC-I. The ABC-I subscale measured the emotional and behavioral symptoms of autism, including aggression towards others, deliberate self-injuriousness, temper tantrums, and quickly changing moods.

NMS is observed most frequently when high-potency agents like haloperidol are administered intramuscularly, but may occur with any neuroleptic agent given for any length of time. Clinical manifestations of NMS include hyperpyrexia, muscle rigidity, altered mental status and autonomic instability irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac arrhythmias. Additional signs may include elevated creatine phosphokinase, myoglobinuria, and acute renal failure. Neuroleptic agents should not be given to patients with active NMS and should be immediately discontinued if currently being administered in such patients. In patients with a history of NMS, introduction or reintroduction of neuroleptic agents should be carefully considered, since NMS may recur.
