What is Ziprasidone HCL?

Ziprasidone is Food and Drug Administration (FDA) approved for the treatment of schizophrenia, and the intramuscular injection form of ziprasidone is approved for acute agitation in schizophrenic patients. Ziprasidone has also received approval for acute treatment of mania and mixed states associated with bipolar disorder. The brand name Geodon has been suggested to bring to mind the phrase ‘down (don) to earth (geo)’ referring to the goals of the medication.

The oral form of ziprasidone is the hydrochloride salt, ziprasidone hydrochloride. The intramuscular form, on the other hand, is the mesylate salt, ziprasidone mesylate trihydrate, and is provided as a lyophilized powder.

What is the Pharmacokinetics for Ziprasidone?

The systemic bioavailability of ziprasidone administered intramuscularly is 100%, or 60%, administered orally with food. After a single dose intramuscular administration, the peak serum concentration typically occurs at about 60 minutes after the dose is administered, or earlier. Steady state plasma concentrations are achieved within one to three days. The mean half-life ranges from two to five hours. Exposure increases in a dose-related manner and following three days of intramuscular dosing, little accumulation is observed.

Ziprasidone absorption is optimally achieved when administered with food. Without a meal preceding dose, the bioavailability of the drug is reduced by approximately 50%.

Ziprasidone is hepatically metabolized by aldehyde oxidase; minor metabolism occurs via cytochrome P450 3A4 (CYP3A4).Medications that induce (e.g. carbamazepine) or inhibit (e.g. ketoconazole) CYP3A4 have been shown to decrease and increase, respectively, blood levels of ziprasidone.

Ziprasidone Adverse effects

Ziprasidone received a black box warning due to increased mortality in elderly patients with dementia-related psychosis. It also slightly increases the QTc interval in some patients and increases the risk of a potentially lethal type of heart arrhythmia known as torsades de pointes. Ziprasidone should be used cautiously in patients taking other medications likely to interact with ziprasidone or increase the QTc interval.

Ziprasidone is known to cause activation into mania in some bipolar patients.This medication can cause birth defects, according to animal studies, although this side effect has not been confirmed in humans.

Adverse events reported for ziprasidone include severe chest pains, impaired erectile function and stimulation, sedation, insomnia, orthostasis, life-threatening neuroleptic malignant syndrome, akathisia, and the development of permanent neurological disorder tardive dyskinesia. Rarely, temporary speech disorders may result.

Recently, the FDA required the manufacturers of some atypical antipsychotics to include a warning about the risk of hyperglycemia and Type II diabetes with atypical antipsychotics. Some evidence suggests that ziprasidone may not be as bad as some of the other atypical antipsychotics (namely, olanzapine (Zyprexa)) at causing insulin resistance and weight gain. In fact, in a trial of long term therapy with ziprasidone, overweight patients (BMI > 27) actually had a mean weight loss overall.However, Ziprasidone is not a weight loss drug. The weight loss reflected in this study on ziprasidone was really reflective of patients who had gained weight on other antipsychotics who were now trending back toward their baseline. According to the manufacturer insert, ziprasidone caused an average weight gain of 2.2 kg (4.8 lbs) (which is significantly lower than other atypicals–clozapine and olanzapine).
