Overview of Novel Oral Hypoglycemic Agents

Type 2 diabetetes approphatepy has evolved signitantly beyond metformin and sulfonylureas. Three major classes of novel oral hypoglycemic agents now dominate clinical practice: sodium- glucose cotconportaporterr 2 (SGLT2) hammitors, glucagon- like peptide- 1 (GLP- 1) receptor agonists, and dipeptidyl peptidase- 4 (DPP- 4) hammetriors.

Mechanisms of Action and Clinical Advantages

SGLT2 hamujące (kanagliflozin, dapagliflozin, empagliflozin) bloki glukozy reabsorption in thee proximal renal tubule, promoting glikosuria and reducing plasma glucose concentration. This mechanism is independent of insulilin secretion and beta- cell function, making these agents effectiva across a wige range of disease duration. Additionally, SGLT2 inhibition reduces sodium reabsorption, leing tteg modese diureditisis and blood prestion. Thadionally plazming, SGLT2 inhibilumume contraction also comcupees reped.

GLP-1 receptor agonisty (oral semaglutide, liraglutide, dulaglutide) mimic the action of endogenous increctins. They stymulate glucose-dependent insulilin secretion, supres glucagon release, slow gastric emptying, and promote central satiety. These glucose-dependent nature of insulin secution minimizes hypoglycemia risk, an important safety ephagetage.
