California Gov. Gavin Newsom announced on Saturday that the state will cut insulin costs by 90% and that it will start manufacturing naloxone, a nasal spray used to reverse opioid overdoses.

The lower insulin cost results from a collaboration between CalRx, a California Department of Health Care Services program, and the non-profit drug manufacturer Civica Rx, according to a news release from the governor's office. A 10-milliliter vial of insulin will be available for no more than $30, pending approval by the US Food and Drug Administration, says the release.
