Ari pi prazole, olanzapine, quetiapine, risperidone, and ziprasidone are effective as monotherapy or as add-on therapy to lithium or valproate for acute mania. Prophylactic use of antipsychotics can be needed for some patients with recurrent mania or mixed states, but the risks versus benefits must be weighed in view of long-term side effects (e.g., obesity, type 2 diabetes, hyperlipidemia, hyperprolactinemia, cardiac disease, and tardive dyskinesia). 

When an antipsychotic is needed, we prefer using one of the newer atypical agents olanzapine, ziprasidone, risperidone, quetiapine, or aripiprazole. Each of these medications reliably reduces agitation and is well tolerated. In particular, they decrease the potential for acute dystonic reactions and tardive dyskinesia caused by the typical antipsychotics. Both ziprasidone and olanzapine are now available in an injectable form that is very rapidly acting and effective in this setting. 

Tardive dyskinesia refers to uncontrollable facial movements. It is more likely to occur in the elderly. Tardive dyskinesia is commonly associated with the use of antipsychotic drugs, such as haloperidol. The atypical antipsychotics, such as clozapine, olanzapine, risperidone and quetiapine are less likely to cause tardive dyskinesia. 

The main indications for atypical antipsychotics are the acute and maintenance treatment of schizophrenic disorders, with an emphasis on the treatment of refractory and chronic disorders. However, because of the lower risk of EPS and in particular of tardive dyskinesia, there is a tendency toward a wider range of indications for some of the atypical neuroleptics. Favorable effects in drug-induced psychoses have been demonstrated for olanzapine. Clozapine seems effective in the treatment and relapse prevention of manic episodes and bipolar disorders, and risperidone has been shown to have good efficacy in conduct disorders and in the pervasive developmental disorders. 

Atypical neuroleptics. Because of the limited effectiveness and safety of conventional neuroleptics in TS, clinicians have turned to a new generation of neuroleptics that have been introduced for the treatment of schizophrenia. Risperidone, a member of a class of antipsychotics that blocks both DA and serotonin receptors, has been established as superior to placebo and equal, or superior, to haloperidol in the treatment of schizophrenia (Chouinard et al. 1993 Marder and Meibach 1994]. Risperidone has a more favorable side-effect profile than that of conventional neuroleptics and may have less potential for producing tardive dyskinesia. Compared with haloperidol, fewer extrapyramidal side effects are observed with risperidone in doses of 6 mg/ day or less. As encouraging reports appear in the literature (Lombroso et al. 1995 Stamenkovic et al. 1994 van der Linden et al. 1994], risperidone is currently being widely used by clinicians to treat tic disorders. 

In CONCLUSION, the use of the "classical" neuroleptics, as exemplified by the phenothiazines, thioxanthines, butyrophenones and diphenylbutyl-piperidines, has been a landmark in the pharmacotherapy of schizophrenia and psychotic disorders. The efficacy of such drugs in the alleviation of the symptoms of schizophrenia is universally accepted. However, it is also evident that they have a spectrum of adverse effects that frequently renders their long-term use problematic. Side effects such as akathisia, Parkinsonism, tardive dyskinesia and the all too frequent changes in peripheral autonomic activity are largely predictable from the structure of the molecules and the basic animal pharmacology data. Such adverse effects, and the difficulties encountered when attempting to reduce their frequency and severity by concurrent medication, has stimulated the development of "atypical" neuroleptics such as clozapine and risperidone which, hopefully, will combine efficacy with a reduction in side effects.

Extrapyramidal effects Parkinsonian symptoms, akathisia (motor restlessness), and tardive dyskinesia (inappropriate postures of the neck, trunk, and limbs) occur with chronic treatment. Blocking of dopamine receptors in the nigrostriatal pathway probably causes these unwanted parkinsonian symptoms. Clozapine and risperidone exhibit a low incidence of these symptoms. 

Risperdal was first marketed in 1994 as an atypical neuroleptic. The clinical trials, most of which lasted a few weeks, were too short to determine the rate of tardive dyskinesia and many other adverse effects. Indeed, the brief controlled clinical trials used for the approval of both clozapine and risperidone do not provide sufficient information to determine either efficacy or safety since the drugs would be used for months and years in individual patients, rather than for a few weeks (see chapter 13). Patients taking the medications over the coming years will provide the experimental data. However, since Risperdal is a potent dopamine blocker, it should have been anticipated that it would cause similar adverse reactions as the older neuroleptics. In my own experience, I have evaluated many cases of tardive dyskinesia caused by Risperdal, Zyprexa, and Geodon. Meanwhile, the Food and Drug Administration (FDA) has required the same tardive dyskinesia and neuroleptic malignant syndrome warnings on the labels of clozapine and risperidone as on the labels of the older neuroleptics. 

All the neuroleptics (see the appendix) can cause TD, including the atypical neuroleptics such as clozapine (Weller et al., 1993), olanzapine (Her-ran, 1999), and risperidone (Addington et al., 1995 Buzan, 1996 Kumar et al., 2000 Kwon, 2004). Aripiprazole (Abilify) has been considered one of the safer atypicals, but there are already reports of tardive dyskinesia (Maytal et al., 2006 Oommen et al., 2006). Given that the atypicals,... 

Tardive or withdrawal dyskinesias, some transient but others irreversible, seen in 8%-51% of antipsychotic-treated children and adolescents, mandate caution regarding casual use of these drugs. Tardive dyskinesia has been documented in children and adolescents after as brief a period of treatment as 5 months and may appear even during periods of constant medication dose. Cases of tardive dyskinesia have been reported in youths treated with risperidone, indicating that atypical antipsychotics may also cause this serious adverse reaction.

The medical records of 151 hospitalized elderly psychiatric patients (mean age 71 years) have been analysed (8). Of 114 patients treated with risperidone (mean duration of treatment 17 days mean dose 3 mg/day), 78% responded. Adverse events were reported in 20 patients, including new-onset extrapyramidal effects in four tremor in four sedation in three hypotension in three diarrhea in two tardive dyskinesia in two and chest pain, anxiety, restlessness, itching, insomnia, and falls in one each. 

Risperidone has also been used in combination with topiramate in a Spanish multicenter study in 58 patients (28 men and 30 women mean age 41 years) with bipolar I disorder, with manic but not mixed episodes (20). Risperidone (mean dose 2.7 mg/day) and topiramate (mean dose 236 mg/day) were started with a maximum 48-hour time difference risperidone was used for acute manic symptoms and topiramate for longer-term stabilization and prevention of relapse. The incidence of any adverse event was 64%, mostly somnolence, paresthesia, dizziness, tremor, weight loss (n = 27 mean change -1.1 kg), extrapyramidal disorders, gastrointestinal effects, and cognitive disturbances. One patient developed tardive dyskinesia during the study and there were five dropouts because of adverse effects adverse effects that required withdrawal of risperidone but not topiramate were amenorrhea (n = 3) and sexual dysfunction (n = 1). 

Tardive dyskinesia has occasionally been reported with risperidone (SEDA-20, 53 SEDA-21, 59 SEDA-22, 68) (82-87).

Tardive dyskinesia was studied in 330 elderly patients with dementia (mean age 83 years) (94). They were enrolled in a 1-year open study, in which the modal risperidone dose was 0.96 mg/day and the median duration of use was 273 days. The 1-year cumulative incidence of persistent tardive dyskinesia among the 225 patients without dyskinesia at baseline was 2.6%, and patients with dyskinesia at baseline had significant reductions in severity. 

Attention deficit hyperactivity disorder (ADHD) may be a susceptibility factor for risperidone-induced tardive dyskinesia and withdrawal dyskinesia. Both conditions have occurred in patients with a past or recent history of attention deficit hyperactivity disorder.
