MHRA Authorises Once-Weekly Insulin for Type 2 Diabetes
The UK's MHRA approved Eli Lilly's once-weekly insulin efsitora alfa (Onswik) for type 2 diabetes, reducing injections from 365 to 52 yearly. NICE recommends it for NHS use, citing comparable glucose control to daily insulins and potential cost savings. It may benefit hundreds of thousands of patients, especially those needing assistance with daily injections.
