Chronic mirabegron treatment improves insulin sensitivity, glucose effectiveness, and pancreatic beta-cell function in healthy women.

Mirabegron, taken at 100mg daily for 4 weeks, significantly improved insulin sensitivity and glucose handling in healthy women. This suggests beta-3 stimulation is a potent lever for metabolic health, though the high dose used here caused mild cardiovascular side effects, suggesting future drugs need better selectivity.
