A pharmacist contacted perrigo on (b)(6) 2020 and reported that a consumer returned an albuterol sulfate inhaler because it would not dispense.The complaint sample was received and tested by the manufacturing site, catalent, and the weight of the canister indicated that there was no hfa (propellant) or dha (dehydrated alcohol) remaining in the canister.Perrigo was notified by catalent that this was confirmed as a malfunction on (b)(6) 2020.The catalent investigation determined that the cannister lip was deformed at some point "prior" to crimping and is believed to have created a "slow leak" that was not detected through the 100% leak detection and 100% weight check manufacturing controls.Reserve samples of the same batch were analyzed by catalent and met specification.
