Trulicity (generic name: dulaglutide) is a once-weekly injectable medication approved by the FDA for managing Type 2 diabetes mellitus. Developed by Eli Lilly, Trulicity belongs to the class of drugs known as GLP-1 receptor agonists, which mimic the action of the hormone glucagon-like peptide-1 to regulate blood sugar levels. Unlike traditional oral diabetic medications that require daily dosing and rigid meal coordination, Trulicity provides a hassle-free, once-weekly dosing schedule. This makes it an attractive option for busy individuals or those who struggle with medication adherence.
