The in vitro plasma protein binding of ziprasidone was not altered by warfarin or propranolol, two highly protein-bound drugs, nor did ziprasidone alter the binding of these drugs in human plasma. In a 4-week, placebo-controlled trial (n=139) comparing 2 fixed doses of ziprasidone (20 and 60 mg twice daily) with placebo, only the 60 mg dose was superior to placebo on the BPRS total score and the CGI severity score. Distribution: Ziprasidone has a mean apparent volume of distribution of 1.5 L/kg. When agitation presents as an acute risk, these medications can be given as an intramuscular (IM) dose for even more rapid onset of action, and when time is of essence. DRESS consists of a combination of three or more of the following: cutaneous reaction (such as rash or exfoliative dermatitis), eosinophilia, fever, lymphadenopathy and one or more systemic complications such as hepatitis, nephritis, pneumonitis, myocarditis, and pericarditis. The two drugs are so compatible that you can mix them together in the same syringe. Over 325 of these subjects participated in trials involving the administration of multiple doses. Weight gain has been observed with atypical antipsychotic use. In long-term (at least 1 year), placebo-controlled, flexible-dose studies in schizophrenia, the mean change from baseline in random triglycerides for ziprasidone 2040 mg BID was +26.3 mg/dL (N=15); for ziprasidone 6080 mg BID was -39.3 mg/dL (N=10); and for placebo was +12.9 mg/dL (N=9). Schizophrenia and bipolar I disorder are associated with increased adverse perinatal outcomes, including preterm birth. One patient had a history of prolonged QTc and a screening measurement of 489 msec; QTc was 503 msec during ziprasidone treatment. 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. 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. Ziprasidone intramuscular is intended for intramuscular use only and should not be administered intravenously. Consistent with these in vitro results, population pharmacokinetic evaluation has not revealed any significant pharmacokinetic differences between smokers and nonsmokers. Drugs in Syringe Compatibility Y-Site Injection Compatibility (1:1 Mixture) Additionally, in some cases one brand of product may be compatible but another brand of drug is not. Offspring developmental delays (decreased pup weights) and neurobehavioral functional impairment (eye opening air righting) were observed at doses of 5 mg/kg/day (0.2 times the MRHD based on mg/m2 body surface area) or greater. Patients with these diagnoses were excluded from premarketing clinical studies. Although a single fixed-dose haloperidol arm was included as a comparative treatment in one of the three short-term trials, this single study was inadequate to provide a reliable and valid comparison of ziprasidone and haloperidol. When taking any two medications, consider this in addition to the fact that they have different mechanisms of action. Patients being considered for ziprasidone treatment that are at risk of significant electrolyte disturbances should have baseline serum potassium and magnesium measurements. Chemically, ziprasidone mesylate trihydrate is 5-[2-[4-(1,2-benzisothiazol-3-yl)-1-piperazinyl]ethyl]-6-chloro-1,3-dihydro-2H-indol-2-one, methanesulfonate, trihydrate. 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)]. Dystonia - Class Effect: Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. Dopamine Epinephrine (Adrenalin) Esmolol (Brevibloc) Furosemide (Lasix) Heparin Insulin (regular) Lidocaine (Xylocaine) Lorazepam (Ativan) Magnesium . Severe cutaneous adverse reactions are sometimes fatal. Titration within the range of 4080 mg twice daily (in 20 mg twice daily increments) was permitted for the duration of study (beginning on Day 2). In the ziprasidone-treated patients, neither case suggested a role of ziprasidone. In one study, the higher dose was 20 mg, which could be given up to 4 times in the 24 hours of the study, at interdose intervals of no less than 4 hours. The easiest way to lookup drug information, identify pills, check interactions and set up your own personal medication records. The developmental no-effect dose is 5 mg/kg/day (0.2 times the MRHD based on mg/m2 body surface area). Answer (1 of 3): Generally, any two antipsychotics can be taken together. In clinical trial and postmarketing experience, events of leukopenia/neutropenia have been reported temporally related to antipsychotic agents. Cimetidine at a dose of 800 mg QD for 2 days did not affect ziprasidone pharmacokinetics. This is because the two drugs work with the body in the same. The co-administration of 30 mL of Maalox with ziprasidone did not affect the pharmacokinetics of ziprasidone. Medically reviewed by Drugs.com. chlorproMAZINE LORazepam. All reported reactions are included except those already listed in Table 11 or elsewhere in labeling, those reaction terms that were so general as to be uninformative, reactions reported only once and that did not have a substantial probability of being acutely life-threatening, reactions that are part of the illness being treated or are otherwise common as background reactions, and reactions considered unlikely to be drug-related. Most patients improved promptly with adjunctive treatment with antihistamines or steroids and/or upon discontinuation of ziprasidone, and all patients experiencing these reactions were reported to recover completely. Patients with an established diagnosis of diabetes mellitus who are started on atypical antipsychotics should be monitored regularly for worsening of glucose control. Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system (CNS) pathology. Tiger26 said: I've actually never used the B-52 during residency. Patients who are started on diuretics during Ziprasidone therapy need periodic monitoring of serum potassium and magnesium. Available for Android and iOS devices. . Contents should be mixed thoroughly by gently inverting the . The occurrence of rash was related to dose of ziprasidone, although the finding might also be explained by the longer exposure time in the higher dose patients. Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. Vital Sign Changes - Ziprasidone is associated with orthostatic hypotension [see Warnings and Precautions (5.9)]. 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). In this study, no patients had a QTc interval exceeding 500 msec. When meds are run together at a Y site, there is actually very little surface area of mixture between the two. Unchanged ziprasidone represents about 44% of total drug-related material in serum. Thus, the potential for drug interactions with ziprasidone due to displacement is minimal. 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. yes. Yes, you can mix geodon and benadryl in the same syringe. no its not good to mix any drugs together in a syringe inless its in a IV bag mixed by a professional but deffinitly dont mix in a single syringe. The BPRS psychosis cluster (conceptual disorganization, hallucinatory behavior, suspiciousness, and unusual thought content) is considered a particularly useful subset for assessing actively psychotic schizophrenic patients. Certain circumstances may increase the risk of the occurrence of torsade de pointes and/or sudden death in association with the use of drugs that prolong the QTc interval, including (1) bradycardia; (2) hypokalemia or hypomagnesemia; (3) concomitant use of other drugs that prolong the QTc interval; and (4) presence of congenital prolongation of the QT interval. This higher dose group was not superior to placebo on the BPRS psychosis cluster or on the SANS. GEODON contains the active moiety, ziprasidone in the form of ziprasidone mesylate salt for intramuscular use only. Hypokalemia may result from diuretic therapy, diarrhea, and other causes. The effects on fertility are reversible [see Warnings and Precautions (5.15) and Use in Specific Populations (8.3)]. 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%. Ziprasidone binds with relatively high affinity to the dopamine D2 and D3, serotonin 5HT2A, 5HT2C, 5HT1A, 5HT1D, and 1-adrenergic receptors (Ki s of 4.8, 7.2, 0.4, 1.3, 3.4, 2, and 10 nM, respectively), and with moderate affinity to the histamine H1 receptor (Ki=47 nM). Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. In cases of severe extrapyramidal symptoms, anticholinergic medication should be administered. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Whether ziprasidone will cause torsade de pointes or increase the rate of sudden death is not yet known [see Warnings and Precautions (5.3)]. However, some patients may require treatment with ziprasidone despite the presence of the syndrome. Therefore, ziprasidone should not be given with: Ziprasidone is contraindicated in individuals with a known hypersensitivity to the product. Ziprasidone should not be used with any drug that prolongs the QT interval [see Contraindications (4.1)]. Persistently prolonged QTc intervals may also increase the risk of further prolongation and arrhythmia, but it is not clear that routine screening ECG measures are effective in detecting such patients. One case of priapism was reported in the premarketing database. Any unused portion should be discarded. Agranulocytosis (including fatal cases) has also been reported. Therefore, a safe and effective dose for use could not be established. Metabolism and Elimination: Ziprasidone is extensively metabolized after oral administration with only a small amount excreted in the urine (<1%) or feces (<4%) as unchanged drug. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Ziprasidone and other antipsychotic drugs should be used cautiously in patients at risk for aspiration pneumonia. Somnolence led to discontinuation in 0.3% of the patients in short-term clinical trials in adults. Rather, ziprasidone should be avoided in patients with histories of significant cardiovascular illness, e.g., QT prolongation, recent acute myocardial infarction, uncompensated heart failure, or cardiac arrhythmia. 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. Can you. Ziprasidone rebalances dopamine and serotonin to improve thinking, mood, and behavior. Other severe cutaneous adverse reactions, such as Stevens-Johnson syndrome, have been reported with ziprasidone exposure. Some people, especially the elderly, may also experience impairment in thinking, judgment, and motor coordination. 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. If antiarrhythmic therapy is administered, disopyramide, procainamide, and quinidine carry a theoretical hazard of additive QT-prolonging effects that might be additive to those of ziprasidone. 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. Fertility rate was reduced at 160 mg/kg/day (8 times the MRHD based on mg/m2 body surface area). It has a molecular weight of 412.94 (free base), with the following chemical name: 5-[2-[4-(1,2-benzisothiazol-3-yl)-1-piperazinyl]ethyl]-6-chloro-1,3-dihydro-2H-indol-2-one. As with other antipsychotic drugs, ziprasidone should be used cautiously in patients with a history of seizures or with conditions that potentially lower the seizure threshold, e.g., Alzheimer's dementia. In vivo studies have revealed no effect of ziprasidone on the pharmacokinetics of estrogen or progesterone components. The types of relapse events observed included depressive, manic, and mixed episodes. Can you mix geodon and lorazepam in the same syringe? Based on in vitro studies utilizing human liver enzymes, ziprasidone is not a substrate for CYP1A2; smoking should therefore not have an effect on the pharmacokinetics of ziprasidone. Conditions that lower the seizure threshold may be more prevalent in a population of 65 years or older. Single-dose vials require reconstitution prior to administration. The efficacy of intramuscular ziprasidone in the management of agitated schizophrenic patients was established in two short-term, double-blind trials of schizophrenic subjects who were considered by the investigators to be "acutely agitated" and in need of IM antipsychotic medication. Patients with a pre-existing low WBC or a history of drug induced leukopenia/neutropenia should have their complete blood count (CBC) monitored frequently during the first few months of therapy and should discontinue GEODON at the first sign of decline in WBC in the absence of other causative factors. Intramuscular administration of ziprasidone for more than three consecutive days has not been studied. Increases in serum prolactin were observed in a 1-month dietary study in female, but not male, mice at 100 and 200 mg/kg/day (or 2.5 and 5 times the MRHD based on mg/m2 body surface area). Steady-state concentrations are achieved within one to three days of dosing. Each mL of reconstituted solution contains 20 mg ziprasidone. Pooled data from short-term, placebo-controlled studies in schizophrenia and bipolar disorder are presented in Tables 58. Prescriptions for ziprasidone should be written for the smallest quantity of capsules consistent with good patient management in order to reduce the risk of overdose. 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. Analyses of 17 placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. The effect on fertility appeared to be in the female since fertility was not impaired when males given 160 mg/kg/day (8 times the MRHD based on mg/m2 body surface area) were mated with untreated females. Ziprasidone's activity is primarily due to the parent drug. Introduction. 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. Published data from observational studies, birth registries, and case reports on the use of atypical antipsychotics during pregnancy do not report a clear association with antipsychotics and major birth defects. There is no information on the effects of ziprasidone on milk production. 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. Generally, in the maintenance phase, patients continued on the same dose on which they were stabilized during the stabilization phase. Ziprasidone should be discontinued in patients who are found to have persistent QTc measurements >500 msec [see Warnings and Precautions (5.3)]. 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. Geodon and Benadryl can interact with each other, which can cause serious side effects. Advise patients that GEODON may cause extrapyramidal and/or withdrawal symptoms (agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder) in a neonate. There was a reproducible mutagenic response in the Ames assay in one strain of S. typhimurium in the absence of metabolic activation. All interactions studies have been conducted with oral ziprasidone. Note that for the flexible dose studies in both schizophrenia and bipolar disorder, each subject is categorized as having received either low (2040 mg BID) or high (6080 mg BID) dose based on the subject's modal daily dose. -1-Piperazinyl ] ethyl ] -6-chloro-1,3-dihydro-2H-indol-2-one, methanesulfonate, trihydrate QTc was 503 msec during ziprasidone therapy need monitoring!
