Filgrastim, sold under the brand name Neupogen among others, is a medication used to treat low blood neutrophils due to a number of causes. This includes when it occurs following chemotherapy, radiation poisoning, HIV/AIDS, or is of unknown cause.
Bradycardia and heart block occur in 1 to 3 percent of patients receiving amiodarone. 2 Amiodarone-induced proarrhythmia occurs at an annual rate of less than 1 percent.
Amiodaroneâs half-life is very long (58 days), therefore, you would not need to worry about the medication being pushed in the same way as adenosine. For cardiac arrest, Amiodarone should be pushed quickly and then followed with 20 ml of NS. This can be 15, 30, or 60 sec. The sooner that it is in the system, the sooner it will be able to have its antiarrhythmic effects on the body.
