Amiodarone Hydrochloride50mg/ml Concentrate for Solution for Injection/Infusion - Potential for crystallisation
Dear Healthcare professional,
In agreement withthe Medicines and Healthcare products Regulatory Agency (MHRA), the UK MarketingAuthorisation Holders of products containingamiodaronehydrochloride 50 mg/ml concentrate,namely hameln pharmagmbh, BowmedIbisqus Limited/Ibigen S.r.l. Aventis Pharma Limited trading as Sanofi, would like to informyou ofthe following:
Reports have been received of visible crystals of amiodarone hydrochloride within thesolution of asmall number of ampoules of marketedproduct
Healthcare professionals are advised to:
Visuallyinspect ampoules of amiodarone for clarity,particulate matter, discolouration the integrity of the container
Onlyuse thesolution if it is clear the container is undamaged intact
Backgroundinformation
Amiodaronehydrochloride is an antiarrhythmicusedfor the management of life-threatening ventricular arrhythmias(tachycardiaor fibrillation) and supraventricular arrhythmias (fibrillation or flutter) and Wolff-Parkinson-White Syndrome.
The potential for amiodarone solutionsto crystallise and the associated potential for amiodarone- inducedphlebitis are known havebeenpreviously discussed in the scientific literature [1, 2].
Amiodaronein aqueous solutionis associated with crystallisationdueto poor solubility.To overcome this, the moleculeistypically solubilised as part of amicellar systemusing an excipient, such as polysorbate 80, which acts as asurfactant.Anybreakdown ofthis micellar system canlead to crystallisation of amiodarone in solution,whichhas been observed both at high concentrations of amiodarone(e.g.in ampoules of concentrate)andatlow concentrations (e.g.ininfusionbags during administration).
Whilethe potential for amiodarone solutionsto crystallise is known, following receipt of a small number of reports of crystallisationin ampoules from separate batches of product,andthesubsequentinvestigationsundertaken, the MarketingAuthorisationHolders would liketohighlight this potential for crystallisation tohealthcare professionals.
Adverse reactions
Asnotedin the prescribing information for the products, infusion phlebitis is listed as one ofthe most common adverse drug effects reported with intravenous amiodarone hydrochloride.
There has beenno identified increasein the reporting of adverse reactionsthat would be considered related tothe crystallisation ofamiodaroneduringinfusion (e.g. phlebitis,thrombophlebitis). Whilethisdoesn’texclude the possibility of adversehealth consequences,itfurther supportsthe overallprobability thatthe occurrence of such reactions is low.
Recommendations foruse
Toinform healthcare professionals ofthepotential for crystallisation,the MarketingAuthorisation Holders,in agreement withthe MHRA,have issued this Direct HealthcareProfessional Communication to provide additional information for healthcare professionals.
Healthcare professionalsshould continue to follow the advice below:
Before use, thesterile concentrateshouldbevisuallyinspected for clarity,particulate matter, discolourationtheintegrity ofthe container. Thesolutionshould onlybe usedif itis clear the container is undamaged intact.
Althoughtheuse of in-line filters isnotconsidered to be standardpracticeinthe UK for allinfusions of medicinal products, healthcare professionals may wishto considertheuse of in-line filters forinfusions of solutions that are knownto crystallise, including solutions ofamiodarone [1,2].
