Several patients with rash had signs and symptoms of associated systemic illness, e.g., elevated WBCs. The phase IV clinical study analyzes what interactions people who take Geodon and Benadryl have. Patients with low serum potassium and/or magnesium should be repleted with those electrolytes before proceeding with treatment. Each mL of ziprasidone mesylate for injection (when reconstituted) contains 20 mg of ziprasidone and 4.7 mg of methanesulfonic acid solubilized by 294 mg of sulfobutylether -cyclodextrin sodium (SBECD). In the 4- and 6-week placebo-controlled trials in adults, somnolence was reported in 14% of patients on ziprasidone compared to 7% of placebo patients. Hypokalemia may result from diuretic therapy, diarrhea, and other causes. It is not recommended to mix benadryl and ativan in the same syringe as they are both central nervous system depressants. Proliferative changes in the pituitary and mammary glands of rodents have been observed following chronic administration of other antipsychotic agents and are considered to be prolactin-mediated. chlorproMAZINE LORazepam. Can you. As ziprasidone is cleared substantially by the liver, the presence of hepatic impairment would be expected to increase the AUC of ziprasidone; a multiple-dose study at 20 mg twice daily for 5 days in subjects (n=13) with clinically significant (Childs-Pugh Class A and B) cirrhosis revealed an increase in AUC 012 of 13% and 34% in Childs-Pugh Class A and B, respectively, compared to a matched control group (n=14). If you are prescribed both medications, it is important to take them as directed by your healthcare provider. As with other antipsychotic drugs and placebo, sudden unexplained deaths have been reported in patients taking ziprasidone at recommended doses. The two drugs are so compatible that you can mix them together in the same syringe. In long-term (at least 1 year), placebo-controlled, flexible-dose studies in schizophrenia, the mean change from baseline in random total cholesterol for ziprasidone 2040 mg BID was +2.5 mg/dL (N=14); for ziprasidone 6080 mg BID was -19.7 mg/dL (N=10); and for placebo was -28.0 mg/dL (N=9). Over 325 of these subjects participated in trials involving the administration of multiple doses. Ziprasidone was significantly more effective than placebo in reduction of the MRS total score and the CGI-S score. Ketoconazole, a potent inhibitor of CYP3A4, at a dose of 400 mg QD for 5 days, increased the AUC and Cmax of ziprasidone by about 3540%. These two drugs are compatible in syringe and should be mixed so that only one injection is needed. Absorption: Ziprasidone is well absorbed after oral administration, reaching peak plasma concentrations in 6 to 8 hours. Titration within the range of 4080 mg twice daily (in 20 mg twice daily increments) was permitted for the duration of the study. A half-life of 7.1 hours was observed in subjects with cirrhosis compared to 4.8 hours in the control group. In the first phase of the trial, ECGs were obtained at the time of maximum plasma concentration when the drug was administered alone. It entirely depends on what you plan on starting the patient on the following day, and whether or not you're LOOKING for sedation (Geodon reportedly has less sedation compared to typicals). The mechanism of action of ziprasidone in the treatment of the listed indications could be mediated through a combination of dopamine type 2 (D2) and serotonin type 2 (5HT2) antagonism. In the trial, ECGs were obtained at the time of maximum plasma concentration following two injections of ziprasidone (20 mg then 30 mg) or haloperidol (7.5 mg then 10 mg) given four hours apart. Ziprasidone dosed adjunctively to lithium in a maintenance trial of bipolar patients did not affect mean therapeutic lithium levels. This higher dose group was not superior to placebo on the BPRS psychosis cluster or on the SANS. The developmental no-effect dose is 5 mg/kg/day (0.2 times the MRHD based on mg/m2 body surface area). Ziprasidone and other antipsychotic drugs should be used cautiously in patients at risk for aspiration pneumonia. In arriving at a diagnosis, it is important to exclude cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) In vitro studies using human liver subcellular fractions indicate that S-methyldihydroziprasidone is generated in two steps. Patients were observed for "impending psychotic relapse," defined as CGI-improvement score of 6 (much worse or very much worse) and/or scores 6 (moderately severe) on the hostility or uncooperativeness items of the PANSS on two consecutive days. GEODON for Injection is available in a single-dose vial as ziprasidone mesylate (20 mg ziprasidone/mL when reconstituted according to label instructions) [see Dosage and Administration (2.1)]. The co-administration of 30 mL of Maalox with ziprasidone did not affect the pharmacokinetics of ziprasidone. Advise patients that GEODON may cause extrapyramidal and/or withdrawal symptoms (agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder) in a neonate. Contains 10 of NDC 0049-1203-01, Geodon for Injection Possible risk factors for leukopenia/neutropenia include pre-existing low white blood cell count (WBC) and history of drug induced leukopenia/neutropenia. Approximately 6.5% (18/279) of ziprasidone-treated patients in short-term, placebo-controlled studies discontinued treatment due to an adverse reaction, compared with about 3.7% (5/136) on placebo. Approximately 20% of the dose is excreted in the urine, with approximately 66% being eliminated in the feces. Depressive, manic, and mixed episodes accounted for 53%, 34%, and 13%, respectively, of the total number of relapse events in the study. Population pharmacokinetic analysis of schizophrenic patients enrolled in controlled clinical trials has not revealed evidence of any clinically significant pharmacokinetic interactions with benztropine, propranolol, or lorazepam. A person should not mix Ativan and Xanax. As with other drugs that antagonize dopamine D2 receptors, ziprasidone elevates prolactin levels in humans. But the LSD will likely not do anything on account of Geodon's high affinity blockade of the 5HT2a receptor. Data sources include IBM Watson Micromedex (updated 2 Apr 2023), Cerner Multum (updated 17 Apr 2023), ASHP (updated 10 Apr 2023) and others. Dose Dependency of Adverse Reactions in Short-Term, Fixed-Dose, Placebo-Controlled Trials. Any unused portion should be discarded. There are risks to the mother associated with untreated schizophrenia or bipolar I disorder and with exposure to antipsychotics, including GEODON, during pregnancy (see Clinical Considerations). Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. It is generally not recommended to mix Geodon and Ativan in the same syringe, as there is a potential for interaction between the two medications. yes. Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmia). Ziprasidone use should be avoided in combination with other drugs that are known to prolong the QTc interval [see Contraindications (4.1) and Drug Interactions (7.4)]. Introduction. Ziprasidone intramuscular has not been systematically evaluated in elderly patients (65 years and over). Unchanged ziprasidone represents about 44% of total drug-related material in serum. There was no clear evidence for a dose-response relationship within the 20 mg twice daily to 100 mg twice daily dose range. No appreciable affinity was exhibited for other receptor/binding sites tested, including the cholinergic muscarinic receptor (IC50 >1 M). There were insufficient data to examine population subsets based on age and race. The most common reaction associated with dropout was rash, including 7 dropouts for rash among ziprasidone patients (1%) compared to no placebo patients [see Warnings and Precautions (5.8)]. Dizziness which includes the adverse reaction terms dizziness and lightheadedness. However, the syndrome can develop, although much less commonly, after relatively brief treatment periods at low doses. Carbamazepine is an inducer of CYP3A4; administration of 200 mg twice daily for 21 days resulted in a decrease of approximately 35% in the AUC of ziprasidone. Additional signs may include elevated creatinine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure. The results of the intramuscular ziprasidone trials follow: GEODON for Injection should be stored at 25C (77F); excursions permitted to 15C to 30C (59F to 86F) [see USP Controlled Room Temperature] in dry form. Ziprasidone is an antagonist at the D2, 5HT2A, and 5HT1D receptors, and an agonist at the 5HT1A receptor. New York, NY 10017. Acute Treatment of Agitation in Schizophrenia. Dosage modifications for age or gender are, therefore, not recommended. Package insert / product label The efficacy of oral ziprasidone in the treatment of schizophrenia was evaluated in 5 placebo-controlled studies, 4 short-term (4- and 6-week) trials and one maintenance trial. This combination works faster than using either drug alone. None of these adverse reactions occurred individually at an incidence greater than 10% in bipolar mania trials. Therefore, a safe and effective dose for use could not be established. Although the prevalence of the syndrome appears to be highest among the elderly, especially elderly women, it is impossible to rely upon prevalence estimates to predict, at the inception of antipsychotic treatment, which patients are likely to develop the syndrome. While these symptoms can occur at low doses, they occur more frequently and with greater severity with high potency and at higher doses of first generation antipsychotic drugs. Esophageal dysmotility and aspiration have been associated with antipsychotic drug use. While all of the drugs in the class have been shown to produce some metabolic changes, each drug has its own specific risk profile. It is essential to periodically monitor serum electrolytes in patients for whom diuretic therapy is introduced during ziprasidone treatment. . There is little potential for drug interactions with ziprasidone due to displacement [see Clinical Pharmacology (12.3)]. The ideal first line medications to use for rapid tranquilization of an acutely agitated patient are benzodiazepines and antipsychotics. The conditions and duration of treatment with ziprasidone included open-label and double-blind studies, inpatient and outpatient studies, and short-term and longer-term exposure. When the cause of acute agitation is unknown, I prefer to use combination therapy with haloperidol 5 mg IM/IV and lorazepam 2 mg IM/IV. The most common reactions associated with dropout in the ziprasidone-treated patients were akathisia, anxiety, depression, dizziness, dystonia, rash and vomiting, with 2 dropouts for each of these reactions among ziprasidone patients (1%) compared to one placebo patient each for dystonia and rash (1%) and no placebo patients for the remaining adverse reactions. GEODON for Injection is available in a single-dose vial as ziprasidone mesylate (20 mg ziprasidone/mL when reconstituted according to label instructions) [see Dosage and Administration (2.1)]. For patients with diseases, conditions, or medications that could exacerbate these effects, complete fall risk assessments when initiating antipsychotic treatment and recurrently for patients on long-term antipsychotic therapy. However, in some circumstances there may be compelling reasons for mixing two or more parenteral drug solutions in the same infusion bag, in the same syringe or at a Y . This question came up when I was asked why Haldol, Ativan, and Benadryl can't go in the same syringe. Geodon and Benadryl can interact with each other, which can cause serious side effects. Ziprasidone was significantly superior to placebo in time to relapse, with no significant difference between the different dose groups. Instruct patients to report the onset of any conditions that put them at risk for significant electrolyte disturbances, hypokalemia in particular, including but not limited to the initiation of diuretic therapy or prolonged diarrhea. Ziprasidone is primarily cleared via three metabolic routes to yield four major circulating metabolites, benzisothiazole (BITP) sulphoxide, BITP-sulphone, ziprasidone sulphoxide, and S-methyldihydroziprasidone. Anyone who finds an antipsychotic inadequate will most likely either never find any antipsychotic adequate or will find a different drug more helpful or more risk-effective tha. Each mL of ziprasidone mesylate for injection (when reconstituted) affords a colorless to pale pink solution that contains 20 mg of ziprasidone and 4.7 mg of methanesulfonic acid solubilized by 294 mg of sulfobutylether -cyclodextrin sodium (SBECD). Doses of 10 mg may be administered every two hours; doses of 20 mg may be administered every four hours up to a maximum of 40 mg/day. After intramuscular administration of single doses, peak serum concentrations typically occur at approximately 60 minutes post-dose or earlier and the mean half-life (T) ranges from two to five hours. Jun 27, 2014. There is no specific antidote to ziprasidone, and it is not dialyzable. Undesirable alterations in lipids have been observed in patients treated with atypical antipsychotics. In the patient taking the largest confirmed amount, 3,240 mg, the only symptoms reported were minimal sedation, slurring of speech, and transitory hypertension (200/95). Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Ziprasidone had no effect on serum prolactin in rats in a 5-week dietary study at the doses that were used in the carcinogenicity study. COMPATIBILITY OF DRUGS COMBINED IN A SYRINGE. Reconstitution of vial: Using aseptic technique, add 1.2 mL of Sterile Water for Injection, USP to the single-dose vial and shake vigorously until all the drug is dissolved. Ziprasidone was tested in the Ames bacterial mutation assay, the in vitro mammalian cell gene mutation mouse lymphoma assay, the in vitro chromosomal aberration assay in human lymphocytes, and the in vivo chromosomal aberration assay in mouse bone marrow. In the same long-term fixed-dose schizophrenia study, the proportion of subjects with 7% increase in weight from baseline for ziprasidone 20 mg BID was 5.6% (N=72); for ziprasidone 40 mg BID was 2.9% (N=69); for ziprasidone 80 mg BID was 5.7% (N=70) and for placebo was 2.9% (N=70). Although fewer patients have been treated with GEODON, it is not known if this more limited experience is the sole reason for the paucity of such reports. Metabolism and Elimination: Although the metabolism and elimination of IM ziprasidone have not been systematically evaluated, the intramuscular route of administration would not be expected to alter the metabolic pathways. Since no preservative or bacteriostatic agent is present in this product, aseptic technique must be used in preparation of the final solution. 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. In the second phase of the study, the effect of ziprasidone on QTc length was not augmented by the presence of a metabolic inhibitor (ketoconazole 200 mg twice daily). The mean change in QTc from baseline was calculated for each drug, using a sample-based correction that removes the effect of heart rate on the QT interval. Thus, the potential for drug interactions with ziprasidone due to displacement is minimal. The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. Mixing is best avoided. It is important to emphasize that, although the reactions reported occurred during treatment with ziprasidone, they were not necessarily caused by it. Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately. Ziprasidone at a dose of 20 mg twice daily did not affect the pharmacokinetics of concomitantly administered oral contraceptives, ethinyl estradiol (0.03 mg) and levonorgestrel (0.15 mg). Common interactions include weight increased among females and dyspnoea among males. A study directly comparing the QT/QTc prolonging effect of oral ziprasidone with several other drugs effective in the treatment of schizophrenia was conducted in patient volunteers. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Generally, in the maintenance phase, patients continued on the same dose on which they were stabilized during the stabilization phase. Because ziprasidone is highly metabolized, with less than 1% of the drug excreted unchanged, renal impairment alone is unlikely to have a major impact on the pharmacokinetics of ziprasidone. GEODON is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning and Warnings and Precautions (5.1)]. There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, including GEODON, during pregnancy. Ziprasidone should not be used with any drug that prolongs the QT interval [see Contraindications (4.1)]. Increased prolactin levels were also observed in animal studies with this compound, and were associated with an increase in mammary gland neoplasia in mice; a similar effect was not observed in rats [see Nonclinical Toxicology (13.1)]. Consistent with in vitro results, a study in normal healthy volunteers showed that ziprasidone did not alter the metabolism of dextromethorphan, a CYP2D6 model substrate, to its major metabolite, dextrorphan. Note that a 30 mg dose of intramuscular ziprasidone is 50% higher than the recommended therapeutic dose. It is recommended that patients being considered for ziprasidone treatment who are at risk for significant electrolyte disturbances, hypokalemia in particular, have baseline serum potassium and magnesium measurements. Applies to: Thorazine (chlorpromazine) and Ativan (lorazepam) Using chlorproMAZINE together with LORazepam may increase side effects such as dizziness, drowsiness, confusion, and difficulty concentrating. Other Adverse Reactions Observed During the Premarketing Evaluation of Oral Ziprasidone. Some people, especially the elderly, may also experience impairment in thinking, judgment, and motor coordination. In a 4-week, placebo-controlled trial (n=200) comparing 3 fixed doses of ziprasidone (5, 20, and 40 mg twice daily), none of the dose groups was statistically superior to placebo on any outcome of interest. Do not mix with other drugs (i.e., in the same syringe). Ziprasidone rebalances dopamine and serotonin to improve thinking, mood, and behavior. The possibility of multiple drug involvement should be considered. The possibility of a suicide attempt is inherent in psychotic illness or bipolar disorder, and close supervision of high-risk patients should accompany drug therapy. Close medical supervision and monitoring should continue until the patient recovers. There was no statistically significant change in the urinary dextromethorphan/dextrorphan ratio. My preferred agitation regimen is the following: 1) Known or suspected psychosis: 5mg Droperidol +/- 5-10 mg Versed, generally IM pending IV access--takes 5-10 min. There have been few reports of hyperglycemia or diabetes in patients treated with GEODON. Weight gain has been observed with atypical antipsychotic use.
