The Inhaler, Metered Dose Or Dry Powder (CDER or CBER Led) is a not-classified drug-device combination product consisting of metered dose or dry powder inhalers that deliver drug substances to the site of action through the inhalation route. It is unclassified because the primary mode of action is attributed to the drug component regulated by CDER or CBER, reviewed by the Anesthesiology panel. The product code is QKS, with no regulation number assigned. The device is not an implant and is not life-sustaining.

No 510(k) clearances found for "QKS". Try a different K-number, product code, or device name.

What is a Predicate Device?

A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.

Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.

Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
