Abstract:
As a consequence of the presence of two ester groups in its molecule the main decomposition route of pipecuronium bromide (active ingredient of Arduan injection) is hydrolysis. In addition to this, autoxidation can also take place. In order to obtain a stable dosage form liophylized ampoules containing mannitol were prepared. Mannitol is not only a filling material but its role is also to decrease the dielectric constant of the solvent water thus increasing the stability of the drug substance before and during the liophylization procedure and after the dissolution of the content of the ampoules for administration. In order to protect the drug molecule against oxidation inert gas atmosphere was used during the production of the ampoules. The preparation is compatible with basic infusion solutions.
