Starter doses of the weight-loss drug Zepbound are now available in single-dose vials, drug manufacturer Eli Lilly announced Tuesday, a move the company says will “significantly” expand supply as it sees continued high demand.

The weight loss drug Wegovy was shown to reduce the risk of heart attack, stroke or heart disease-related death by 20% in a major clinical trial in people with cardiovascular disease, the first to show a weight loss drug alone can have such protective effects.
