GLP-1 medications work through several complementary mechanisms: Enhancing insulin secretion from pancreatic beta cells in a glucose-dependent manner, which helps lower blood sugar levels Suppressing glucagon release , thereby reducing hepatic glucose production Slowing gastric emptying , which prolongs satiety and reduces appetite Acting on appetite centres in the brain , leading to reduced caloric intake and weight loss Commonly prescribed GLP-1 receptor agonists available in the UK include semaglutide (Ozempic, Wegovy, Rybelsus [oral form]), dulaglutide (Trulicity), liraglutide (Victoza, Saxenda), and exenatide (Byetta, Bydureon)
Cytochrome P450 2C9 (Cyp2C9) Substrates Theoretically, gymnema might increase or decrease levels of drugs metabolized by CYP2C9
These symptoms are typically dose-dependent and tend to diminish over time as patients develop tolerance to the medication
Results and discussion Systemic GLP-1RA treatment reverses aging-associated transcriptomic changes in diverse mouse brain cell types We hypothesized that GLP-1RAs may be potent anti-aging therapeutics that impact diverse brain cell types
