Risperidone (N=69) Ziprasidone (N=135) Cost Utility of the Latest Antipsychotic Drugs in Schizophrenia Study (CUTLASS)  227 patients with schizophrenia who were judged by their treating clinician to potentially benefit from a new antipsychotic medication trial "because of inadequate response or adverse effects" were randomized to receive either a first- or a second-generation antipsychotic (excluding clozapine). The specific antipsychotic was chosen by the treating clinician. The primary outcome measure, assessed by blind raters at 12, 26, and 56 weeks, was "quality of life" reflecting social and vocational function. Symptom changes were secondary outcomes.  There was no difference in any outcome measures between groups. Average Monthly Symptom Scores Rosenheck R et al. Cost Effectiveness of Second-Generation Antipsychotics and Perphenazine in a Randomized Trial of Treatment for Chronic Schizophrenia Am J Psychiatry 2006; 163:2080-89 Comparison of second-generation vs firstgeneration drugs for schizophrenia: a meta-analysis (Leucht, et al, Lancet 2009)    Clozapine, olanzapine and risperidone were better than firstgeneration drugs for overall efficacy, with small to medium effect sizes Other second generation drugs were NOT more efficacious, even for negative symptoms Second-generation drugs induced fewer EPSE than haloperidol, but only a few have fewer EPSE than low potency first-generation drugs  BUT:     Second-generation drugs induced more weight gain (except ziprasidone and aripiprazole) Only clozapine demonstrated improved quality of life compared to older drugs Atypicals are very expensive – cost effectiveness not proven Need more rigorous studies to accurately define older firstgeneration drugs Antipsychotic medication reduces relapse rates: but……not all SGA > FGA Risk of relapse in one year: Consistently taking medications: 20-30% Not taking medications consistently: 65-80% Leucht, et al; Lancet 2009: olanzapine and risperidone significantly better than first-generation antipsychotics in preventing relapse. Aripiprazole and clozapine: no significant difference. No studies available for other second-generation antipsychotics Updated APA Practice Guidelines for Treatment of Schizophrenia Guideline Watch (November 2009): The 2004 guideline recommends that selection of an antipsychotic agent be guided by the patient's past medication history, current symptoms and co-occurring conditions, other concurrent treatments, and preferences. The guideline states that secondgeneration agents should be considered first-line options for patients in the acute phase, mainly because of the decreased risk of extrapyramidal side effects and tardive dyskinesia, but acknowledges debate over the relative advantages, disadvantages, and cost-effectiveness of first- and secondgeneration agents. The guideline also states that for some patients, a first-generation agent may be an appropriate first-line option. This latter recommendation has been strengthened by the results of several recently published effectiveness studies that suggest that the first-generation antipsychotics perphenazine and molindone may be equally effective as second-generation agents. In fact, the distinction between first- and second-generation antipsychotics appears to have limited clinical utility. Updated NICE Guidelines for Treatment of Schizophrenia (UK) Pharmacological interventions For people with newly diagnosed schizophrenia, offer oral antipsychotic medication. Provide information and discuss the benefits and side-effect profile of each drug with the service user. The choice of drug should be made by the service user and healthcare professional together, considering: − the relative potential of individual antipsychotic drugs to cause extrapyramidal side effects (including akathisia), metabolic side effects (including weight gain) and other side effects (including unpleasant subjective experiences) − the views of the carer where the service user agrees. Do not initiate regular combined antipsychotic medication, except for short periods (for example, when changing medication).

Delay eating by choosing to do another activity before you eat or snack. - Learn relaxation or mindfulness, and practice it daily ↓↓↓ Try to keep your intake down ↓↓↓ - Keep a journal or log to make yourself aware of your food intake - Use smaller sized plates & glasses to make a “full” portion with less food. - Keep a calorie count - Beware “hidden” calories, especially in soda etc. - Make sure you have plenty of low calorie and high fiber (makes you feel full) food around to do your eating with, especially the food you use to eat small portions often - Swap vegetables for sweets, swap pretzels for chips - Drink plenty of water - Avoid fruit juices and sodas – drink water or seltzer instead of other cold drinks - Drink your coffee or tea “black” – without sugar, creamer, milk or sweeteners - ↑↑↑ Try to keep your energy output up ↑↑↑ - Exercise daily – brisk walks (striding fast enough so you could converse but it would be “breathy”) are thought to be a “best” exercise – 30 minutes to an hour daily. Two 15 minute walks equals one 30 minute walk if time is a problem. - Seek active rather than sedentary activities - Take stairs rather than elevators. - Plan your errands and activities to include walking - Keep a journal or log to make yourself aware of your activity level - Pharmacologic Interventions for weight loss  FDA- approved  use only if BMI >30 or >27 if metabolic syndrome is present  Initiate only after a 6-month period with weight loss <1 lb/week despite adherence to “healthy lifestyle regimen”  Sibutramine, Orlistat, Phentermine  Off-label  Glucophage (Metformin)  Topiramate  Bupropion + naltrexone, phentermine + topiramate, bupropion + zonisamide  New/investigational  Lorcaserin (selective serotonin 2C receptor agonist)  Betahistine (H1 agonist/H3antagonist) Managing Side Effects of Your Medication The most common side effects of antipsychotic medications are: Dry mouth, constipation, lack of energy, drowsiness, upset stomach, dizziness, feeling hungrier than usual, gaining weight, insomnia, tremors, and restlessness. These side effects generally do not bother people enough to stop taking their medications. Here are some suggestions for managing side effects: If you experience this… Sleep disturbance Try this:   Feeling hungrier than usual  Gaining weight      Dizziness  Dry mouth  Constipation  Upset stomach    Restlessness Talk with your doctor about adjusting the doses or timing of your medication schedule Drink plenty of water or other sugar-free drinks – 6 to 8 glasses a day. Drink a glass of water before meals to help you feel fuller. When you want a snack, try eating a half-cup of fruit or raw vegetables or a rice cake. Chew sugar-free gum. Instead of snacking, try taking a walk. Get some extra exercise each day. Talk with your doctor before making any major changes in your exercise routine. Stand up slowly if you have been sitting or lying down. If you become anxious, try diaphragmatic breathing or relaxation. Enjoy sugar-free mints or sugar-free hard candy. Let them melt in your mouth. Eat foods that are high in fiber, such as bran cereals and raw vegetables. Try taking your medication with a meal Talk to your doctor about a dosage change. Talk to your doctor about medication options for managing this side effect. **Contents of this handout courtesy of Eli Lilly and Co. – modified by Julie Pease, M.D. Informed Consent PATIENT MEDICATION CONSENT, AGREEMENT TO REPORT ADVERSE SYMPTOMS, and ASSUMPTION OF RISK AGREEMENT Note: No medication is absolutely positively 100% risk free. Even taking over-the-counter medicines, like Aspirin and Tylenol for example, can result in serious side effects or even death. However, all prescribed medicines are approved as safe and effective by the Food and Drug Administration (FDA), and most of the time they cause little or no harm. Nevertheless, there are some specific concerns that you should be aware of with certain medicines that are commonly prescribed, and that is the purpose of this medication consent. 1. Atypical Antipsychotics (ABILIFY, CLOZARIL, GEODON, RISPERIDAL, SEROQUEL, SYMBYAX, and ZYPREXA): These may cause or result in certain adverse medical problems: a. Elevated blood sugar, diabetes, and weight gain: elevated blood sugars, in some cases extreme and associated with coma or death, have been reported in patients treated with these medications. These changes may occur with or without weight gain. I agree to report any significant weight gain and/or symptoms of elevated blood sugar (including increased thirst, increased urination, increased eating, and weakness) to my doctor. Patients who develop any of these symptoms should have a test for elevated blood sugar and cholesterol. b. Increased risk of stroke and a higher death rate in elderly patients with dementia. These medications are not indicated for the treatment of agitation except in patients with schizophrenia or bipolar disorder. a. Neuroleptic Malignant Syndrome (NMS): this is a rare but potentially life-threatening condition with symptoms of unstable blood pressure, confusion, coma, delirium, fever, and/or muscle stiffness. b. Elevated prolactin levels: this may be associated with enlarged breasts, breast discharge, sexual dysfunction, osteoporosis, and very rarely pituitary (brain) tumors. 2. Tardive Dyskinesia (TD): All antipsychotic medications, including haloperidol (HALDOL) and fluphenazine (PROLIXIN), those listed in #1 above, and others such as _______________________ may result in a condition called tardive dyskinesia (TD). The symptoms of TD, which are primarily abnormal movements or muscle cramps and which may be irreversible, have been explained to me and I accept the risk and agree to report any muscle cramps or abnormal movements to my doctor immediately. 6.Pregnancy: Taking medication during pregnancy exposes the fetus to medication and can present a risk to the unborn child. Some psychiatric medications are known to have a higher risk of birth defects (e.g. Depakote); others may be continued during pregnancy with minimal risk depending upon the medication and the circumstances. This needs to be considered carefully in the decision making process for medication use by women of childbearing ages. If planning to become pregnant, I agree to discuss my medications with my doctor before trying to conceive. If I do become pregnant while taking medication, I agree to call my doctor immediately so that we can discuss the risks/benefits of continuing medication or the need/process by which to stop the medication if the situation and risks of continuing warrant that. All medications are passed into breast milk in differing amounts. Some may be used with relative safety during breastfeeding and others are not recommended for use during lactation. 10. Off-label Use: One or more of the medications I have been prescribed is or are prescribed “off-label.” This means that the medication is prescribed for a use not approved by the Food and Drug Administration (FDA), use at doses above those recommended, or use for periods of time longer than approved. 11. Driving a Car or Use of Machinery OR Use With Alcohol: One or more of the medications prescribed to me may adversely affect my ability to drive a motor vehicle or operate machinery.
