Ziprasidone hydrochloride monohydrate (0-500 nM, 150 seconds) blocks wild-type hERG currents [2]. Cell Viability Assay[2] Cell Line: HEK-293 Cell Concentration: 0-500 nM Incubation Time: 150 sec Results: Blocks wild-type hERG current (IC50 = 120 nm) in a voltage- and concentration-dependent manner.

Ziprasidone hydrochloride monohydrate (oral gavage; 20 mg/kg; once daily; 7 weeks) results in weight loss, lower physical activity levels, higher resting energy expenditure, and increased thermogenesis in the cold [3] . Animal model: 8-week-old female Sprague-Dawley rats, weighing 200 to 250 g[3] Dosage: 20 mg/kg Administration method: oral gavage; 20 mg/kg; once a day; 7-week results: significant weight loss (P = 0.031), had lower levels of physical activity (P = 0.016), had higher resting energy expenditure (P < 0.001), and showed greater thermogenic capacity when cold (P < 0.001).

Effects During Pregnancy and Lactation
◉ Summary of Use during Lactation
Because there is little published experience with ziprasidone during breastfeeding, other antipsychotic agents may be preferred, especially while nursing a newborn or preterm infant. A safety scoring system finds ziprasidone possible to use cautiously during breastfeeding. Infants breastfed during maternal use of ziprasidone should be monitored for excess sedation, irritability, poor feeding, and extrapyramidal symptoms, such as tremors and abnormal muscle movements.
◉ Effects in Breastfed Infants
A woman took ziprasidone 40 mg and citalopram 60 mg daily throughout pregnancy and postpartum. She breastfed extensively, except for occasional formula feedings by others. At 6 months of age, a pediatrician found the infant to be healthy with normal growth and development.
Patients enlisted in the National Pregnancy Registry for Atypical Antipsychotics who were taking a second-generation antipsychotic drug while breastfeeding (n = 576) were compared to control breastfeeding patients who were not treated with a second-generation antipsychotic (n = 818). Of the patients who were taking a second-generation antipsychotic drug, 60.4% were on more than one psychotropic. A review of the pediatric medical records, no adverse effects were noted among infants exposed or not exposed to second-generation antipsychotic monotherapy or to polytherapy. The number of women taking ziprasidone was not reported.
◉ Effects on Lactation and Breastmilk
Prolactin elevation has occurred during ziprasidone treatment, and galactorrhea has been reported, often in adolescents. However, prolactin elevation might be more transient and less severe than with phenothiazines. The prolactin level in a mother with established lactation may not affect her ability to breastfeed.
Patients enlisted in the National Pregnancy Registry for Atypical Antipsychotics who were taking a second-generation antipsychotic drug while breastfeeding (n = 576) were compared to control breastfeeding patients who had primarily diagnoses of major depressive disorder and anxiety disorders, most often treated with SSRI or SNRI antidepressants, but not with a second-generation antipsychotic (n = 818). Among women on a second-generation antipsychotic, 60.4% were on more than one psychotropic compared with 24.4% among women in the control group. Of the women on a second-generation antipsychotic, 59.3% reported “ever breastfeeding” compared to 88.2% of women in the control group. At 3 months postpartum, 23% of women on a second-generation antipsychotic were exclusively breastfeeding compared to 47% of women in the control group. The number of women taking ziprasidone was not reported.
