Ziprasidone (Page 8 of 9)

14.2 Bipolar I Disorder (Acute Mixed or Manic Episodes and Maintenance Treatment as an Adjunct to Lithium or Valproate)

Acute Manic and Mixed Episodes Associated with Bipolar I Disorder

The efficacy of ziprasidone was established in 2 placebo-controlled, double-blind, 3-week monotherapy studies in patients meeting DSM-IV criteria for bipolar I disorder, manic or mixed episode with or without psychotic features. Primary rating instruments used for assessing manic symptoms in these trials were: (1) the Mania Rating Scale (MRS), which is derived from the Schedule for Affective Disorders and Schizophrenia-Change Version (SADS-CB) with items grouped as the Manic Syndrome subscale (elevated mood, less need for sleep, excessive energy, excessive activity, grandiosity), the Behavior and Ideation subscale (irritability, motor hyperactivity, accelerated speech, racing thoughts, poor judgment) and impaired insight; and (2) the Clinical Global Impression-Severity of Illness Scale (CGI-S), which was used to assess the clinical significance of treatment response.

The results of the oral ziprasidone trials in adult bipolar I disorder, manic/mixed episode follow: in a 3-week placebo-controlled trial (n=210), the dose of ziprasidone was 40 mg twice daily on Day 1 and 80 mg twice daily on Day 2. Titration within the range of 40–80 mg twice daily (in 20 mg twice daily increments) was permitted for the duration of the study. Ziprasidone was significantly more effective than placebo in reduction of the MRS total score and the CGI-S score. The mean daily dose of ziprasidone in this study was 132 mg. In a second 3-week placebo-controlled trial (n=205), the dose of ziprasidone was 40 mg twice daily on Day 1. Titration within the range of 40–80 mg twice daily (in 20 mg twice daily increments) was permitted for the duration of study (beginning on Day 2). Ziprasidone was significantly more effective than placebo in reduction of the MRS total score and the CGI-S score. The mean daily dose of ziprasidone in this study was 112 mg.

Maintenance Therapy

The efficacy of ziprasidone as adjunctive therapy to lithium or valproate in the maintenance treatment of bipolar I disorder was established in a placebo-controlled trial in patients who met DSM-IV criteria for bipolar I disorder. The trial included patients whose most recent episode was manic or mixed, with or without psychotic features. In the open-label phase, patients were required to be stabilized on ziprasidone plus lithium or valproic acid for at least 8 weeks in order to be randomized. In the double-blind randomized phase, patients continued treatment with lithium or valproic acid and were randomized to receive either ziprasidone (administered twice daily totaling 80 mg to 160 mg per day) or placebo. Generally, in the maintenance phase, patients continued on the same dose on which they were stabilized during the stabilization phase. The primary endpoint in this study was time to recurrence of a mood episode (manic, mixed or depressed episode) requiring intervention, which was defined as any of the following: discontinuation due to a mood episode, clinical intervention for a mood episode (e.g., initiation of medication or hospitalization), or Mania Rating Scale score ≥ 18 or a MADRS score ≥18 (on 2 consecutive assessments no more than 10 days apart). A total of 584 subjects were treated in the open-label stabilization period. In the double-blind randomization period, 127 subjects were treated with ziprasidone, and 112 subjects were treated with placebo. Ziprasidone was superior to placebo in increasing the time to recurrence of a mood episode. The types of relapse events observed included depressive, manic, and mixed episodes. Depressive, manic, and mixed episodes accounted for 53%, 34%, and 13%, respectively, of the total number of relapse events in the study.

PATIENT SUMMARY OF INFORMATION ABOUT
Ziprasidone Capsules
(ziprasidone HCl)

Information for patients taking ziprasidone or their caregivers

This summary contains important information about ziprasidone. It is not meant to take the place of your doctor’s instructions. Read this information carefully before you take ziprasidone. Ask your doctor or pharmacist if you do not understand any of this information or if you want to know more about ziprasidone.

What Is ziprasidone?

Ziprasidone is a type of prescription medicine called a psychotropic, also known as an atypical antipsychotic. Ziprasidone can be used to treat symptoms of schizophrenia and acute manic or mixed episodes associated with bipolar disorder. Ziprasidone can also be used as maintenance treatment of bipolar disorder when added to lithium or valproate.

Who Should Take ziprasidone?

Only your doctor can know if ziprasidone is right for you. ziprasidone may be prescribed for you if you have schizophrenia or bipolar disorder.

Symptoms of schizophrenia may include:

  • hearing voices, seeing things, or sensing things that are not there (hallucinations)
  • beliefs that are not true (delusions)
  • unusual suspiciousness (paranoia)
  • becoming withdrawn from family and friends

Symptoms of manic or mixed episodes of bipolar disorder may include:

  • extremely high or irritable mood
  • increased energy, activity, and restlessness
  • racing thoughts or talking very fast
  • easily distracted
  • little need for sleep

If you show a response to ziprasidone, your symptoms may improve. If you continue to take ziprasidone there is less chance of your symptoms returning. Do not stop taking the capsules even when you feel better without first discussing it with your doctor.

It is also important to remember that ziprasidone capsules should be taken with food.

What is the most important safety information I should know about ziprasidone?

Ziprasidone is not approved for the treatment of patients with dementia-related psychosis. Elderly patients with a diagnosis of psychosis related to dementia treated with antipsychotics are at an increased risk of death when compared to patients who are treated with placebo (a sugar pill).

Ziprasidone is an effective drug to treat the symptoms of schizophrenia and the manic or mixed episodes of bipolar disorder. However, one potential side effect is that it may change the way the electrical current in your heart works more than some other drugs. The change is small and it is not known whether this will be harmful, but some other drugs that cause this kind of change have in rare cases caused dangerous heart rhythm abnormalities. Because of this, ziprasidone should be used only after your doctor has considered this risk for ziprasidone against the risks and benefits of other medications available for treating schizophrenia or bipolar manic and mixed episodes.

Your risk of dangerous changes in heart rhythm can be increased if you are taking certain other medicines and if you already have certain abnormal heart conditions. Therefore, it is important to tell your doctor about any other medicines that you take, including non-prescription medicines, supplements, and herbal medicines. You must also tell your doctor about any heart problems you have or have had.

Who should NOT take ziprasidone?

Elderly patients with a diagnosis of psychosis related to dementia. Ziprasidone is not approved for the treatment of these patients.

Anything that can increase the chance of a heart rhythm abnormality should be avoided. Therefore, do not take ziprasidone if:

  • You have certain heart diseases, for example, long QT syndrome, a recent heart attack, severe heart failure, or certain irregularities of heart rhythm (discuss the specifics with your doctor)
  • You are currently taking medications that should not be taken in combination with ziprasidone, for example, dofetilide, sotalol, quinidine, other Class Ia and III anti-arrhythmics, mesoridazine, thioridazine, chlorpromazine, droperidol, pimozide, sparfloxacin, gatifloxacin, moxifloxacin, halofantrine, mefloquine, pentamidine, arsenic trioxide, levomethadyl acetate, dolasetron mesylate, probucol or tacrolimus.

What To Tell Your Doctor Before You Start Ziprasidone

Only your doctor can decide if ziprasidone is right for you. Before you start ziprasidone, be sure to tell your doctor if you:

  • have had any problem with the way your heart beats or any heart related illness or disease
  • any family history of heart disease, including recent heart attack
  • have had any problem with fainting or dizziness
  • are taking or have recently taken any prescription medicines
  • are taking any over-the-counter medicines you can buy without a prescription, including natural/herbal remedies
  • have had any problems with your liver
  • are pregnant, might be pregnant, or plan to get pregnant

  • have ever had an allergic reaction to ziprasidone or any of the other ingredients of ziprasidone capsules. Ask your doctor or pharmacist for a list of these ingredients
  • have low levels of potassium or magnesium in your blood

Your doctor may want you to get additional laboratory tests to see if ziprasidone is an appropriate treatment for you.

Ziprasidone And Other Medicines

There are some medications that may be unsafe to use when taking ziprasidone, and there are some medicines that can affect how well ziprasidone works.

Possible Side Effects

Because these problems could mean you’re having a heart rhythm abnormality, contact your doctor IMMEDIATELY if you:

  • Faint or lose consciousness
  • Feel a change in the way that your heart beats (palpitations)

Common side effects of ziprasidone include the following and should also be discussed with your doctor if they occur:

For a list of all side effects that have been reported, ask your doctor or pharmacist for the ziprasidone Professional Package Insert.

What To Do For An Overdose

In case of an overdose, call your doctor or poison control center right away or go to the nearest emergency room.

Other Important Safety Information

A serious condition called neuroleptic malignant syndrome (NMS) can occur with all antipsychotic medications including ziprasidone. Signs of NMS include very high fever, rigid muscles, shaking, confusion, sweating, or increased heart rate and blood pressure. NMS is a rare but serious side effect that could be fatal. Therefore, tell your doctor if you experience any of these signs.

Delayed-onset drug reaction called drug reaction with eosinophilia and systemic symptoms (DRESS) can occur with ziprasidone. Signs of DRESS may include rash, fever, and swollen lymph nodes. Other severe cutaneous adverse reactions (SCAR), such as Stevens-Johnson syndrome can occur with ziprasidone. Signs of Stevens-Johnson syndrome may include rash with blisters which could include ulcers in mouth, skin shedding, fever and target-like spots in the skin. DRESS and other SCAR are sometimes fatal; therefore, tell your doctor immediately if you experience any of these signs.

Adverse reactions related to high blood sugar (hyperglycemia), sometimes serious, have been reported in patients treated with atypical antipsychotics. There have been few reports of hyperglycemia or diabetes in patients treated with ziprasidone, and it is not known if ziprasidone is associated with these reactions. Patients treated with an atypical antipsychotic should be monitored for symptoms of hyperglycemia.

Dizziness caused by a drop in your blood pressure may occur with ziprasidone, especially when you first start taking this medication or when the dose is increased. If this happens, be careful not to stand up too quickly, and talk to your doctor about the problem.

Before taking ziprasidone, tell your doctor if you are pregnant or plan on becoming pregnant. It is advised that you don’t breast feed an infant if you are taking ziprasidone.

Because ziprasidone can cause sleepiness, be careful when operating machinery or driving a motor vehicle.

Since medications of the same drug class as ziprasidone may interfere with the ability of the body to adjust to heat, it is best to avoid situations involving high temperature or humidity.

It is best to avoid consuming alcoholic beverages while taking ziprasidone.

Call your doctor immediately if you take more than the amount of ziprasidone prescribed by your doctor.

Ziprasidone has not been shown to be safe or effective in the treatment of children and teenagers under the age of 18 years old.

Keep ziprasidone and all medicines out of the reach of children.

How To Store ziprasidone

Store ziprasidone capsules at room temperature (59°F to 86°F or 15°C to 30°C).
