Amiodarone (AMI) has proven to be a potent anti-arrhythmic compound. Due to the structural similarity between AMI and thyroidhormone, it is possible that the drug could inhibit the activity of the 5'-thyroxine-deiodinase. METHODS AMI analogues resulting from (1) dealkylation, (2) deiodination and (3) deamination were synthesised and used as inhibitors in an in vitro biotransformation reaction of thyroxine
The present invention relates to a stable, sterile, ready to administer parenteral dosage form of amiodarone or its pharmaceutically acceptable salt. Particularly, the present invention provides a stable, sterile, ready to administer parenteral dosage form of amiodarone comprising an aqueous solution comprising amiodarone or its pharmaceutically acceptable salt, an acid, and a polyol, wherein the pH of the solution is in the range of about 2.0 to 4.0, wherein the solution is filled in a plastic container and wherein the solution is free of a solubilizer.
The present invention provides a parenteral dosage form consisting essentially of a solution filled in a container, the solution comprising amiodarone or its pharmaceutically acceptable salt and a sulfo-alkyl ether beta-cyclodextrin in an aqueous vehicle, wherein the solution has a pH in the range of about 2.4 to 3.9 and further wherein the dosage form is sterilized by subjecting the filled container to autoclaving.
