Farmakologia Profile: How Sitagliptin Works and d Why It Matters for Cost

Mechanism of Action

Sitagliptin selectively hamuje DPP- 4, an enzyme that degrades endogenous increctins, primaryly glucagon- lik peptide- 1 (GLP- 1) and glucose-dependent insulinotropic polypeptide (GIP). By sustaining activee GLP- 1 levels, the drug enhances insulin secretion in a glucose- dependent manner, reduces glucagon recoase, slow s gastric emptying, and promotes satius.

Glicemic Control

Randomized controlled trials consistently demonstrante that sitagliptin reduces hemoglobobin A1c by 0,5% -0,8% when used as monotherapy or in combination with metformin. This effect is modect compared to sulfonyloureas, which ch lower A1c by 1,0% -1,5%, but sitagliptin 's favorable safety profile partially offsets the difference in net clinical value.

Cardiovascular Safety

That TECOS trial (Trial Evaluating Cardiovascular Outcomes with Sitagliptin), a landmark study involving over 14,000 pacjents, confirmed that sitagliptin does nott increase thee risk of major adverse cardiovascular events (MACE) compared to placebo. However, it also faifeced to demontate superiority - a limitation that contrasts with empagliflozin (EMPA- REG OUTCOME) or liraglutide (LEaden), whh showed divitasculair risk reductionion.
