Samples received: none.Analysis and results: there is a previous complaint of this batch, closed as justified after the analysis.(b)(4) units of this batch were manufactured and distributed in the market.There are no units in stock.The ampoule received in the previous complaint received had the tip broken.There were polymerization nuclei along the cannula that caused the obstruction of the cannula.Further evaluation was not possible as the ampoule had the tip already broken.Ageing studies were performed with the purpose of provoking the complained defect and study the influence of environmental conditions in its apparition.-ampoules were stressed for 9 days at 40ºc and 30 % rh.After 4 days of exposure, the stress conditions caused the apparition of some polymerization nuclei along the cannula in the ampoules.However, the liquid glue could still pass through the cannula, that was not obstructed.After 9 days of exposure, the polymerization nuclei observed caused the obstruction of the cannula.In conclusion, the environmental conditions influence the apparition of the polymerization nuclei along the cannula.A temperature of 40ºc caused the formation of polymerization nuclei along the cannula and the obstruction of the cannula after 9 days of exposure.Therefore, and according the instructions for use, histoacryl should be stored at ambient temperature below 22ºc.The ampoule containing the adhesive should only be removed from the aluminium pouch immediately prior to application.Actions on distributed product of this reference/batch: based on the conclusion derived from investigation, it is not required to make actions in distributed product.Corrective/preventive actions: according to our internal procedures, there is no need to establish corrective or preventive actions.Nevertheless, this complaint is recorded for trending analysis to assess if actions are needed in the future.
