That is not really nasal... its got its own device, not like an inhaler (bigger) and not like nasal spray. I think he was asking if there were any ones out now or in the pipeline (being developed or soon to come out) that will be nasal mist delivery. Maybe I misunderstood but that is what I thought the OP meant. Or maybe he misunderstood "inhaleable" which is different from "nasal." Unless I'm misunderstanding those words
