USP Residual Dose Testing of Inhalers
The United States Pharmacopeia (USP) residual dose testing is a critical procedure that ensures inhaler devices deliver the prescribed dosage accurately. This service involves the rigorous measurement of the amount of medication remaining in an inhaler after actuation, which helps to verify compliance with the USP 800 and 814 monographs on hazardous drug management and safe handling.
Our laboratory adheres strictly to the guidelines set forth by the USP. This includes the use of precise instrumentation such as gravimetric balances capable of detecting minute quantities down to micrograms, and calibrated actuation devices that simulate inhaler usage conditions accurately. The process begins with thorough preparation of each sample, ensuring it is at room temperature before testing.
The testing protocol involves several steps: first, the inhaler device undergoes a baseline measurement without actuation. Then, after a standardized number of actuations (usually 10), additional measurements are taken to determine the residual dose within the delivery chamber and in any remaining medication in the canister. The results from these tests provide insights into the performance consistency across multiple units.
For our service, we also analyze the potential risks associated with residual doses, particularly for hazardous drugs. This analysis helps clients understand how to manage these risks effectively and safely handle the devices post-testing.
A key aspect of this testing is ensuring repeatability and reproducibility across tests conducted on different batches or units of inhalers. Our laboratory uses advanced statistical methods to ensure that any variation in results can be attributed to manufacturing variations rather than measurement errors.
Our team comprises experts familiar with the latest USP guidelines, ensuring accurate and reliable testing outcomes. By adhering strictly to these standards, we guarantee that our clients receive precise data regarding their inhaler devices’ compliance with regulatory requirements.
