DUSA by Proveris®: USP <601> A. Apparatus A - Compliant, Consistent, and Crack Resistant
Delivered Dose Uniformity is a critical quality attribute for assessing the safety, effectiveness, and quality of inhaled and nasal drugs. The Dosage Unit Sampling Apparatus (DUSA) serves as a tool for analyzing the dosage delivered and the overall amount of drug released from inhalers, such as pressurized metered dose inhalers (pMDIs) and nasal spray products, ensuring that a consistent amount is delivered to the patient. The Proveris DUSA (Apparatus A) has optimized several areas of the standard DUSA tube design:
- Lightweight yet durable composition
- Leak-free sealing without gaskets
- Easy-to-handle caps
- Simple gasket free cap design enables effective cleaning
