Metronidazole, and other medications in bulk, redistribution

An update on fish medication "Flagyl" aka "Fish-Zole" aka Metronidazole being available - two companies who used to ship this as either "Hex-a-mit" or "Fish-Zole" seem to have either gone out of business or stopped shipping it. The aquarium supply that I finally found it at explained that she immediately knew which medication I was looking for because aquarium enthusiasts are annoyed by how hard it is to find... and now it's only available in 20-GRAM containers!



So now I have plenty of Metronidazole for my Nocarrier rescue, and a 19.5 gram container of 100% pure Metronidazole left over! I know there must be a way to get this in the hands of people who could use it - either first time rescuers, or other PT members?

I doubt a large rescue organization would take it, since it's been opened. Even though it didn't have a seal, if I were them, I'd be very reluctant to accept unverifiable medications even in donation.

I am very open to requests for small amounts, or good ideas on where this can do some good. Has there been any discussion of a donation-sourced meds armory amongst this group, where needed meds can be mailed quickly? it's very easy to build a tiny little database or even a spreadsheet of medications available and contact information. I'd be happy to contribute effort (I'm in SF, and a computer professional by trade.)

Or is the risk of emailing this stuff across state lines just too worrisome?

Hoping this turns into a productive thread.
