[2025-10-02T05:26:35.129107] [PI reasoning] **Identifying FDA Approval Status**

I need to determine which of the listed options is not FDA approved. The drugs mentioned seem to focus on periodontal therapy: 

GEM 21S is FDA approved for use in bone grafts, so that's not the answer. Elyzol, being a topical metronidazole, might not be FDA approved in the U.S., as it's more common in Europe. Periochip, however, is a biodegradable chip that contains chlorhexidine and is FDA approved. So, my best guess is that Elyzol is likely the option that isn’t FDA approved.
