IV Drip Rate Calculator 2 Patients who received intravenous Antiarrhythmics A-fib: 10 to 15 mcg/kg IBW given as above. Effective in @30% of patients. The discoloration resolves over several months after amiodarone is discontinued. Initial Daily Dose of Oral Cordarone 1 week 800-1600 mg 1-3 weeks 600-800 mg >3 weeks* 400 mg # Assuming a 720 mg/day infusion (0.5 mg/min). * Cordarone I.V. is not intended for maintenance treatment. HOW SUPPLIED Cordarone I.V. (amiodarone HCl) is available in packages of 10 ampuls (2 cartons each containing 5 ampuls), 3 mL each, as follows: RECOMMENDATIONS FOR ORAL DOSAGE AFTER I.V. Please see our, 2010synthroid-levoxyl-levothyroxine-342732. Patients who received intravenous amiodarone for less than one week should take 800 to 1,600 mg oral amiodarone per day.2 Patients who received intravenous amiodarone for one to three weeks should take 600 to 800 oral amiodarone per day, and patients who received intravenous amiodarone for more than three weeks should take 400 mg oral amiodarone per day. 4 0 obj Recommendations for conversion to intravenous amiodarone after oral administration: During long-term amiodarone therapy (ie, 4 months), the mean plasma-elimination half-life of the active metabolite of amiodarone is 61 days. Renal Dosing: CRCL 30-40 ml/minute: 100mg every 8 hours CRCL 15-30 ml/minute: 100mg every 12 hours CRCL <15 ml/minute: 100mg every 24 hours, Supplied: (Norpace): Capsule 100 mg, 150 mg (Norpace CR): Capsule (controlled release) 100 mg, 150 mg. A-fib/Flutter: Dosing (adults):: Usual initial dose: 500 mcg orally twice daily. (Glass bottle or polyolefin container) Hypotension, bradycardia, atrioventricular block. In most instances, the toxicity is reversible. Clinically significant hypotension during infusions was seen most often in the first several hours of treatment and was not dose related, but appeared to be related to the rate of infusion. Amiodarone and DEA cross the placenta and both appear in breast milk. Infusion: >3 weeks Amiodarone DEA serum concentrations above 0.05 mg/L are not usually seen until after several days of continuous infusion but with prolonged therapy reach approximately the same concentration as amiodarone. A filter is not required for IV direct administration. From in vitro studies, the protein binding of amiodarone is >96%. In the event of breakthrough episodes of VF or hemodynamically unstable VT, Give 150-mg/100 ml D5W over 10 minutes to minimize potential for hypotension. A patient started on oral (PO) amiodarone approximately 1 week ago (400 mg/day). Assuming that the plan was not to load the patient, you could simply convert to an equivalent IV dose. 2014;148:e15393. Dilution Amiodarone - GlobalRPH Postoperative atrial fibrillation following cardiac surgery: a persistent complication. 3.Drug in bag. If progressive hepatic injury or hepatomegaly occurs or hepatic enzyme levels increase to greater than 3 times normal (or double in a patient with elevated baseline levels): Consider dose reduction or discontinuation.

Dosing (adults): Arrhythmias: Oral: Initial: 200 mg every 8 hours with food (may load with 400 mg if necessary); adjust dose every 2-3 days; usual dose: 200-300 mg every 8 hours; maximum: 1.2 g/day (some patients respond to every 12-hour dosing). Infusion rate: 318 mL/hr. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. Half life: 9 minutes. Consensus follow-up recommendations from the NASPE are summarized in Table 4.4 A form to guide patient monitoring is provided in Figure 1. 1.Desired Dose. concentrations greater than 2 mg/mL should be administered via a central venous catheter). Hypotension should be treated initially by slowing the infusion; additional standard therapy may be needed, including the following: vasopressor drugs, positive inotropic agents, and volume expansion. CONTRAINDICATIONS There are no known contraindications to the use of DIGIBIND. Loading Dose (Daily): (Ventricular Arrhythmias) 800 to 1,600 mg x 1-3 weeks, then 600 to 800 mg x ~1 month, then start maintenance of 400mg/day. This drug should be used at the lowest effective dose in order to prevent the occurrence of side effects. Patients taking amiodarone should not eat grapefruit or drink grapefruit juice because it can inhibit the conversion of amiodarone to an active metabolite. Decrease dose by 30-50% in hepatic insufficiency. Overt liver disease can occur, however, and has been fatal in a few cases. Dosing (adults): IVPB: 0 to 1 mg/50 ml D5W or NS over 10 minutes. Hypotension Consider stopping amiodarone; causal relationship is uncertain. is about 1000 mg over the first 24 hours of therapy, delivered by the following infusion regimen: First Rapid: 150 mg Initiate this drug in a clinical setting where continuous ECGs and cardiac resuscitation are available. PO to IV Amiodarone Switch-Medscape-Apr22,2004. Monitoring: Pacerone, Cordarone, Nexterone, Cordarone IV. Typical amiodarone dosages in the ACLS setting are provided in Table 1.2,10 In patients who require long-term treatment, intravenous dosing should be switched to oral dosing. You've successfully added to your alerts. 6 0 obj Typical dosing regimens are provided in Table 1.10 Because dosages below 300 mg per day are associated with a reduced incidence of pulmonary adverse effects, physicians should aim for a long-term maintenance dosage of 200 mg per day or less.18.
