Atypical antipsychotic drugs Page 11 of 230 Final Report Update 3 Drug Effectiveness Review Project INTRODUCTION “Atypical” antipsychotic agents are used to treat the symptoms of schizophrenia and bipolar disorder (see Table 1 for details). In general, atypical antipsychotics produce antipsychotic responses with fewer acute extrapyramidal side effects than “conventional” antipsychotic drugs. Extrapyramidal side effects are a set of movement disorders such as akathisia, dystonia, and pseudoparkinsonism that resolve when the drug is discontinued or the dosage is lowered. Tardive dyskinesia is a movement disorder that can develop with more prolonged use and may persist even after cessation of the antipsychotic agent. Atypical antipsychotics are associated with lower rates of the development of this neurological side effect in comparison with the older, conventional agents. Atypical antipsychotics may also treat negative symptoms and improve cognitive functioning. Table 1 describes drug indications approved by the US Food and Drug Administration, dosing, and mechanisms of action based on the current product labels for the 10 atypical antipsychotics available in the United States and Canada. Clozapine, the prototypic atypical antipsychotic, was introduced in 1989. Since then, 9 other atypical antipsychotics have been brought to market: risperidone (1993), risperidone long-acting injection (2003), olanzapine (1996), quetiapine (1997), ziprasidone (2001), aripiprazole (2002), extended-release paliperidone (2006), asenapine (2009), iloperidone (2009), and paliperidone long-acting injection (2009). Atypical antipsychotics vary from one another in receptor interaction selection and affinity. These differences in receptor activity are hypothesized to account for differences in efficacy, safety, and tolerability among atypical antipsychotics, as well as in comparison with conventional antipsychotics. Clozapine is an antagonist at dopamine (D1-5) receptors with relatively low affinity for D and D receptors and high affinity for D receptors. Its greater1 2 4 activity at limbic (opposed to striatal) dopamine receptors and lower affinity for D receptors2 may explain the low incidence of extrapyramidal side effects. The antipsychotic effect of risperidone, olanzapine, quetiapine, and ziprasidone is proposed to be primarily via D and serotonin (5-HT ) receptor antagonism. However, each drug2 2 has varying effects on these and other receptors (see Table 1). Antagonism of the 5-HT2 receptors is thought to reduce the extent of D receptor antagonism in the striatum and cortex2 while leaving blockade of D receptors in the limbic area unaffected. These properties are2 thought to account for fewer extrapyramidal side effects and better effects on the negative symptoms of schizophrenia compared with conventional antipsychotics. However, in doses higher than 6 mg daily, the profile for risperidone may become more similar to a conventional antipsychotic due to increased D receptor blockade. Aripiprazole is a partial agonist at D receptors; thus it is an antagonist in the2 presence of high levels of endogenous dopamine and, conversely, acts as an agonist when minimal dopamine is present. Aripiprazole is also a partial agonist at 5-HT1A receptors that may contribute to improvements in anxiety, depression, negative symptoms, and lower incidence of extrapyramidal side effects. Paliperidone is a major active metabolite of risperidone. While risperidone is subject to drug interactions affecting the CYP2D6 enzyme, in vivo studies suggest this isozyme plays a limited role in the clearance of paliperidone. Paliperidone does not require dose adjustments in mild to moderate hepatic impairment, but awaits studies for use in patients with severe hepatic impairment. Iloperidone is an antagonist at the D and 5-HT receptors. It2 2 targets the 5-HT and histamine H1 receptors, thought to play a role in counteracting6 Atypical antipsychotic drugs Page 12 of 230 Final Report Update 3 Drug Effectiveness Review Project extrapyramidal symptoms, sedation, and weight gain. Efficacy of asenapine is believed be a combination of antagonist activity at the dopamine D and 5-HT2 2A receptors. The variation in receptor interaction among these drugs is thought to lead to differences in symptom response and adverse effects.

The extent to which a drug’s adverse effects impact the patient’s ability or willingness to continue taking the drug as prescribed order cardura 4 mg with amex blood pressure by age group. These adverse effects are often referred to as nuisance side effects discount 1 mg cardura with visa blood pressure medication and weight gain, because they are generally considered to not have long-term effects but can seriously impact compliance and adherence to a medication regimen. Treatment regimen: The magnitude of effect of a treatment versus no treatment or placebo; similar to “effect size”. Can be calculated in terms of relative risk (or risk ratio), odds ratio, or risk difference. Two-tailed test (two-sided test): A hypothesis test in which the values that reject the null hypothesis are located in both tails of the probability distribution. For example, testing whether one treatment is different than another (rather than testing whether one treatment is either better than another). Type I error: A conclusion that there is evidence that a treatment works, when it actually does not work (false-positive). Type II error: A conclusion that there is no evidence that a treatment works, when it actually does work (false-negative). Validity: The degree to which a result (of a measurement or study) is likely to be true and free of bias (systematic errors). Variable: A measurable attribute that varies over time or between individuals. Variables can be • Discrete: taking values from a finite set of possible values (e. Washout period: [In a cross-over trial] The stage after the first treatment is withdrawn, but before the second treatment is started. The washout period aims to allow time for any active effects of the first treatment to wear off before the new one gets started.

Cases of PML have been reported in patients taking TYSABRI who were recently or concomitantly treated with immunomodulators or immunosuppressants, as well as in patients receiving TYSABRI as monotherapy[see Warnings and Precautions (5. Under the TOUCH Prescribing Program, only prescribers, infusion centers, and Tysabri Natalizumab pharmacies associated with infusion centers registered with the program are able to prescribe, distribute, or infuse the product. In addition, TYSABRI must be administered only to patients who are enrolled in and meet all the conditions of ® the TOUCH Prescribing Program [see Warnings and Precautions (5. TYSABRI dosing should be withheld immediately at the first sign or symptom suggestive of PML. For diagnosis, an evaluation that includes a gadolinium- enhanced magnetic resonance imaging (MRI) scan of the brain and, when indicated, cerebrospinal fluid analysis for JC viral DNA are recommended [see Contraindications (4), Warnings and Precautions (5. It must never be given subcutaneously, intramuscularly, or intra-arterially. Severe local tissue damage may occur if there is extravasation during administration. Severe injury with Novantrone® Mitoxantrone permanent sequelae can result from intrathecal administration. In order to monitor the occurrence of bone marrow suppression, primarily neutropenia, which may be severe and result in infection, it is recommended that frequent peripheral blood cell counts be performed on all ® patients receiving NOVANTRONE. Cardiotoxicity: Congestive heart failure (CHF), potentially fatal, may occur either during therapy with NOVANTRONE® Disease-modifying drugs for multiple sclerosis Page 107 of 120 Final Report Update 1 Drug Effectiveness Review Project Drug names Active ingredients Boxed warnings or months to years after termination of therapy. Cardiotoxicity risk increases with cumulative NOVANTRONE dose and may occur whether or not cardiac risk factors are present. Presence or history of cardiovascular disease, radiotherapy to the mediastinal/pericardial area, previous therapy with other anthracyclines or anthracenediones, or use of other cardiotoxic drugs may increase this risk. In cancer patients, the risk of symptomatic CHF was estimated to be 2. To mitigate the cardiotoxicity risk with NOVANTRONE, prescribers should consider the following: NOVANTRONE mitoXANTRONE for injection All Patients: All patients should be assessed for cardiac signs and symptoms by history, physical examination, and ECG prior ® to start of NOVANTRONE therapy. All patients should have baseline quantitative evaluation of left ventricular ejection fraction (LVEF) using appropriate methodology (ex. Echocardiogram, multi-gated radionuclide angiography (MUGA), MRI, etc. Multiple Sclerosis Patients: MS patients with a baseline LVEF below the lower limit of ® normal should not be treated with NOVANTRONE.
