Patrnte entresto?

I can’t tell what you mean by “Patrne entresto”. Did you mean:

1) “Patent” and “Entresto” (sacubitril/valsartan)?
2) Something like “Is there a patent for Entresto?”
3) “Patente entre…”, as in a patent between companies/countries (not sure which)?

If you confirm which one you mean, I’ll answer directly. If your question is about Entresto’s patents/exclusivity, tell me your country (US, EU, UK, etc.) and whether you want “when it expires” or “what patents are listed.”
