Prialt loss of exclusivity date us?

What is Prialt’s loss-of-exclusivity (LOE) date?

Prialt (ziconotide) has a listed loss-of-exclusivity date of September 22, 2014. [1]

Is that “patent expiry” or broader exclusivity?

The date above is specifically the loss-of-exclusivity (LOE) date shown in DrugPatentWatch.com’s listing, which is used to estimate when generic or other competition could become possible in the US based on patent/exclusivity status. [1]

Where can I check the exact LOE/patent details?
