Ameridose LLC, the sister company of the Framingham specialty pharmacy that is at the root of a national meningitis outbreak, will now be shut down until at least the end of the year, under an agreement reached Friday with state regulators.

The company is a major supplier for hospitals across the country. To aid hospitals grappling with drug shortages in Massachusetts, state regulators will propose emergency regulations next week that would allow hospital pharmacies to safely share compounded drugs with other hospitals in need.
