Mercial health insurance carriers contract with AdvancePCS to manage their formularies and adjudicate their prescription drug claims. AdvancePCS maintains a computerized pharmacy system that records data on each drug dispensed. Our study included commercially insured patients whose insurance carriers required AdvancePCS to track claims at the patient level, excluding patients whose plans used a single identifier for multiple family members. The analysis data set included outpatient claims adjudicated for 6213824 patients aged 19 years and younger who were enrolled continuously from January through December 2001 and who filed at least one claim for any prescription drug during that period. Each patient's claims were linked using a unique identifier encrypted to ensure confidentiality. A total of 1171 insurers were represented, covering all 50 states as well as US territories. The institutional review board of Duke University Medical Center approved this study. We evaluated claims for 5 atypical antipsychotic drugs-- clozapine, olanzapine, quetiapine, risperidone, and ziprasidone. Period prevalence was defined as the number of children and adolescents per 100000 with at least one prescription drug claim for an atypical antipsychotic in 2001. We calculated the period prevalence for each atypical antipsychotic individually, and we stratified the analysis by sex and age to explore differences in use of the drugs. We used 2 or Fisher exact tests to test for differences in proportions and prevalence rates. All analyses were performed in SAS version 8.0 SAS Institute Inc, Cary, NC ; . RESULTS. Tion of pharmacogenetic and pharmacogenomic studies of antipsychotic drug response. In this presentation, we will review the first generation of candidate gene studies of clozapine response, discuss new data from novel candidate gene studies, and suggest new approaches to optimally utilize the developments in genomics in order to enhance the prospects of the next generation of pharmacogenomic studies of antipsychotic drug response.

Prolongation of the heart rate-corrected QT interval QTc interval ; is a risk factor for sudden cardiac death in a general population of older adults, according to this article. Doctors at the Erasmus Medical Centre in Rotterdam, the Netherlands, and other institutions studied 3, 105 men and 4, 878 women 55 years old participating in The Rotterdam Study. At baseline 19901993 ; and at the first follow up visit 1993-1995 ; , patients underwent electrocardiography to assess the QTc interval. Patients were followed up an average of 6.7 years to determine the incidence of sudden cardiac death. The association between sudden cardiac death and the QTc interval was examined by Cox proportional hazards analyses. During follow up, 125 sudden cardiac deaths occurred approximately 3 per 1, 000 person-years of follow up ; . Subjects with sudden cardiac death had a significantly longer mean QTc than did patients without sudden cardiac death 441.9 vs 431.3ms ; . After data adjustment for age, sex, body mass index, hypertension, cholesterol high-density lipoprotein ratio, diabetes mellitus, myocardial infarction, heart failure and heart rate, an abnormally prolonged QTc interval 450ms in men, 470ms in women ; was associated with a more than twofold higher risk of sudden cardiac death. The risk of sudden cardiac death was even higher in patients with an abnormally prolonged QTc interval who were below the median age of 68 years. These findings suggest that an abnormal QTc prolongation on ECG is an independent risk factor for sudden cardiac death in older adults.

Prescription of antipsychotic drugs by physicians in nonfederal office-based practice in the United States increased significantly from an estimated 3.2 million visits in 1989 CI 2.1 to 4.2 ; to 6.9 million visits in 1997 CI 5.0 to 8.8, p .01 ; . The proportion of antipsychotic visits among all medical visits increased from .46 percent of all visits CI .35 to .57 ; to .88 percent CI .69 to 1.07, p .01 ; . In 1997 prescriptions for atypical antipsychotics constituted 44 percent of prescriptions for all antipsychotic drugs. Two atypical agents were the most widely prescribed antipsychotic drugs in 1997. Risperidone was prescribed during 1.65 million visits, or 22.8 percent of all antipsychotic drug visits. Olanzapine was prescribed during 1.23 million visits, or 17.1 percent of such visits. Clozapine was prescribed during .1 million visits, or 1.4 percent of such visits. Trends in the use of typical and atypical antipsychotic drugs are depicted in Figure 1. Table 1 shows the proportions of and compazine. Been shown that a greater number of ECS treatments produce greater increases in proliferation [49]. Clinically, patients receive multiple, not single, ECS sessions [53]. It is not known if the increased cell proliferation from the multiple sessions translates into clinical efficacy. Following these studies, further investigations examined the question of duration of drug treatment on cell proliferation and cell survival. There was no additional increase in cell proliferation when animals were given fluoxetine for either 14 or 28 days. This indicates that after 14 days of fluoxetine treatment, a plateau in the increased rate of proliferation was reached [3]. This effect was also reported by Santarelli [50], who saw no further increase in proliferation between 11 and 28 days of fluoxetine administration. In contrast to these results, it was found that a longer amount of treatment time was required for fluoxetine to increase cell survival. In a study designed to determine the effect of duration of treatment on cell survival, animals were given an injection of BrdU followed by either 14 or 28 days of fluoxetine and sacrificed on Day 28 [13]. It was shown that 28 but not 14 days of fluoxetine was necessary to increase the total number of cells, which in this study represented the effect of antidepressants on cell survival. Thus, a longer period of antidepressant administration is needed to increase cell survival compared to proliferation. These different time courses may represent different pathways for proliferation and survival, with a longer time course needed for activation of survival pathways. Following these investigations, it was of interest to determine the ultimate differentiation of the proliferating stem cells. In antidepressant- and ECS-treated animals, the majority of the BrdU-positive cells became neurons and not glia, as identified by triple labeling and confocal microscopy [3, 13]. This indicates that antidepressant treatment produces a net number of new neurons neurogenesis ; . The percentage of BrdU-positive cells that became neurons or glia was the same between antidepressant, ECS and control-treated animals, indicating that the antidepressants do not have an influence on the differentiation of cells into their phenotypes. Further studies demonstrated that an antidepressantinduced increase in neurogenesis is restricted to the SGZ of the hippocampus, with no affect on subventricular zone neurogenesis [3]. Additionally, the ability to increase proliferation seems to be restricted to the antidepressant drugs, since antipsychotic drugs such as haloperidol and clozapine do not produce changes in hippocampal proliferation [3, 19]. Other psychotropic drugs such as morphine and heroin produce decreases in proliferation and neurogenesis [54] and cocaine has no effect [19]. Taken together, these studies demonstrate that antidepressants specifically increase hippocampal cell proliferation and neurogenesis. Based on the fact that multiple drug classes and ECS increase proliferation and neurogenesis, this increase may represent a novel mechanism or pathway from which the new generation of antidepressants will be discovered. A working hypothesis in many laboratories is that a factor or factors within neurogenic pathways may represent a novel target for antidepressant drugs. In addition to investigating neurogenic pathways for new targets, another hypothesis from a drug screening perspective.

Autonomic Nervous System Adverse Effects Hypersalivation Clozapine induced hypersalivation can be socially embarrassing and potentially life threatening due to the risk of asphyxiation. The incidence of hypersalivation is estimated to be at 31% 15 ; . Hypersalivation is particularly worse at night and during the early stages of therapy 24 ; . Nonpharmacological strategies that can be useful adjuncts include lowering the dose of clozapine and the use of sugar-free gum to increase the swallowing rate 24 ; . A variety of pharmacological strategies have been employed to counteract hypersalivation, however there have been no large randomly controlled studies completed at this stage. The following agents have been effective in treating clozapine-induced hypersalivation in a few case reports; amitriptyline, benzhexol, benztropine, atropine, hyoscine hydrobromide, ipratropium bromide, terazosin, clonidine and botulinum toxin 24-30 ; . Effective treatment is usually achieved with the use of amitriptyline at a dose of 25-50mg at night. There is a case report of amitriptyline being administered to four patients at a dose of 87100mg and this resulted in either an improvement or cessation of hypersalivation in all patients 25 ; . Hyoscine hydrobromide tablets sucked and swallowed three times a day is widely used in clinical practice, however, there are no publications supporting its efficacy 24 ; . Caution is required when administering clozapine with other anticholinergic drugs 2 ; . Nocturnal Enuresis The incidence of nocturnal enuresis is about 1%, but it may be under-reported because of the embarrassing nature of this adverse effect 15 ; . The pathophysiological cause requires investigation, as nocturnal enuresis can be due directly to the sedative nature of the medication, due to epileptic seizures presenting as nocturnal enuresis or due to diabetes mellitus 31 ; . Nocturnal enuresis can occur at any time during therapy 31 ; . Patients should be advised to avoid fluids in the evening and to void before going to bed. Scheduled night awakenings to empty the bladder can be practised. If necessary, an enuresis alarm can be used 4 ; . Pharmacological methods to manage nocturnal enuresis include desmopressin -4 and losartan. Were initially reported in the late 1960s, 1, 2 and have been more recently documented in larger clinical trials and various national registries.3-8 Although all these studies make it possible to obtain an accurate estimate of the cumulative incidence 0.8% over 15 months ; , the period of occurrence first 6-18 weeks of treatment ; and the predisposing risk factors older age, female gender, ethnic groups ; , the mechanisms underlying the development of clozapine-associated blood dyscrasia have not yet been identified. It has been suggested that bone marrow damage may be caused by immunologic9 or toxic processes that are mediated by metabolites rather than by clozapine itself.5, 8, 10, 11 Furthermore, on the basis of results obtained from human bone marrow cultures incubated with increasing concentrations of clozapine or its metabolites, Gerson and Meltzer10 have postulated that the drug target is likely to be the early hemopoietic stem cell compartment. A similar analysis of cytotoxicity was made in the present study but, in addition, the effects of clozapine and its major metabolite, N-desmethylclozapine, on clonogenic potential were also assessed on purified bone marrow CD34 + progenitor cells, cytokine-driven liquid long term cultures and early hematopoietic progenitor long term culture initiating cells LTC-IC ; . Our results show that the drug and its metabolite have a direct effect on committed but not on primitive hematopoietic cells.

The rapid ionic equilibrium drug exchange at gastric pH from DRC can be retarded by treating the complexes with dilute PEG solutions 2% wt vol ; . The trend of increased residual particle size, proportionate increase in water absorption time, and hence retardation of release with time of PEG immersion is evident. Thus, the drug release from ion exchange resin is retarded at gastric pH. The drug-release retardant effect of PEG treatment is interesting considering properties of Indion 234 and the uses of PEG in formulations and rosuvastatin.

Clinical evidence indicates that the catecholamines dopamine and norepinephrine ; play an important pathophysiologic role in the development of mania. Serotonin also appears to be involved. The original drugs currently available that can effectively alleviate the major symptoms of mania are the lithium salts. Lithium also continues to be shown effective in maintenance treatment of BPD. One theory on its effectiveness is that it is thought to potentiate serotonergic neurotransmission. A variety of medications may be used in conjunction with lithium to regulate mood or stabilize manic patients. Some of these adjunctive medications are benzodiazepines, carbamazepine, clozapine, dopamine receptor agonists, L-tryptophan, and calcium channel blockers CCBs ; . More recently approved medications for acute manic episodes include the anticonvulsant valproic acid see Chapter 13 ; and the antipsychotic agent olanzapine see the Atypical Antipsychotics section later in this chapter ; . Antidepressants are often needed as well to control the depressive side of bipolar disorder. A pharmacologic challenge is to choose antidepressants that are less likely to. 2005 mar 01; : 1-1 clozapine, risperidone, olanzapine, and conventional antipsychotic drug effects on glucose, lipids, and leptin in schizophrenic patients.

The newer atypical antipsychotics such as clozapine, risperidone, olanzapine, quetiapine, ziprasidone, and aripiprazole are safer than the older typical or conventional antipsychotics such as haloperidol and fluphenazine in terms of parkinsonism and tardive dyskinesia.
Clozapine is the only well-documented therapy. The development of a drug from the original idea to the stage of clinical trials takes about 9 years. It can then take a further 15 years for the drug to reach the stage of marketing. As a patent on the drugs expires after about 17 years, the drug companies endeavor to get their product on the market as quickly as possible. Research and development costs millions of dollars so the drug companies try to streamline their clinical trials to save as much money and time as they can and mebeverine.
