Trader 0 4 duac?

I can’t tell what you mean by “Trader 0 4 duac.”

Duac could refer to the prescription acne medicines Duac (a fixed-dose gel containing clindamycin + benzoyl peroxide), but “Trader 0 4” doesn’t match any standard medical or regulatory term I recognize from the information provided.

If you tell me what you’re trying to find—such as:
- a drug price/trader listing,
- a patent/exclusivity question,
- a product strength (e.g., “0.1%/4%” style dosing),
- or a specific Trader/UPC/label code—

…I can give you a precise answer.
