"Mutations in the TTN gene, which are commonly found in idiopathic dilated cardiomyopathy, also seem common in peripartum cardiomyopathyâ€”which may finally help explain why the latter condition occurs, new research suggests.
(amiodarone HCl) Injection for Intravenous Use
NEXTERONE contains amiodarone HCl (C25H29I2NO3•HCl), a class III antiarrhythmic drug. Amiodarone HCl is (2-butyl-3-benzo-furanyl)[4-[2-(diethylamino)ethoxy]-3,5diiodophenyl]methanone hydrochloride.
Amiodarone HCl has the following structural formula:
Amiodarone HCl is a white to slightly yellow crystalline powder, and is very slightly soluble in water. It has a molecular weight of 681.78 and contains 37.3% iodine by weight. NEXTERONE Premixed Injection is a sterile clear, colorless to slightly yellow solution visually free from particulates. NEXTERONE Premixed Injection is available as a ready-to-use, nonpyrogenic, iso-osmotic solution for intravenous administration in 100mL GALAXY containers with 150 mg of amiodarone HCl, USP (1.5mg/mL) in dextrose; and 200mL GALAXY containers with 360 mg of amiodarone HCl, USP (1.8 mg/mL) in dextrose.
NEXTERONE Premixed Injection (150 mg/100 mL, 1.5 mg/mL)
Each mL contains 1.5 mg of amiodarone HCl, USP; 15 mg Betadex Sulfobutyl Ether Sodium, NF; 0.362 mg citric acid anhydrous, 0.183 mg sodium citrate dihydrate and 42.1 mg dextrose anhydrous in water for injection. Sodium hydroxide or hydrochloric acid may have been added to adjust pH.
NEXTERONE Premixed Injection (360 mg/200 mL, 1.8 mg/mL)
Each mL contains 1.8 mg of amiodarone HCl, USP; 18 mg Betadex Sulfobutyl Ether Sodium, NF; 0.362 mg citric acid anhydrous, 0.183 mg sodium citrate dihydrate and 41.4 mg dextrose anhydrous in water for injection. Sodium hydroxide or hydrochloric acid may have been added to adjust pH.

The GALAXY container is fabricated from a specially designed multilayered plastic (PL 2501). Solutions are in contact with the polyethylene layer of the container and can leach out certain chemical components of the plastic in very small amounts within the expiration period. The suitability and safety of the plastic have been confirmed in tests in animals according to the USP biological tests for plastic containers, as well as by tissue culture toxicity studies.
