Background:

Metformin (MET) is a primary oral antidiabetic medication for type 2 diabetes mellitus (T2DM), especially in overweight individuals.
Its core mechanism involves inhibiting hepatic glucose production and improving insulin resistance.
Emerging research suggests MET's potential beyond diabetes, impacting aging, cancer risk, and neurodegenerative diseases.

Purpose of the Study:

To review the diverse biological effects of Metformin (MET) across various health conditions.
To re-evaluate the mechanisms of action, pharmacokinetic properties, and clinical benefits of MET.
To explore MET's role in aging, cancer, obesity, polycystic ovarian syndrome, and Alzheimer's disease.

Main Methods:

Comprehensive literature review of existing clinical and experimental studies on Metformin.
Analysis of Metformin's impact on glucose metabolism, insulin resistance, and cellular pathways.
Examination of pharmacokinetic properties, drug interactions, and genetic factors influencing MET efficacy.

Main Results:

Metformin (MET) demonstrates significant antidiabetic effects through AMPK activation.
Evidence suggests MET may reduce the risk of certain cancers and slow aging processes.
MET shows therapeutic potential in obesity, polycystic ovarian syndrome, and Alzheimer's disease.

Conclusions:

Metformin (MET) possesses a wide range of beneficial biological effects beyond its antidiabetic role.
AMPK activation is a key mechanism underlying MET's metabolic and potential anti-aging benefits.
Further research into MET's pharmacokinetics, drug interactions, and diverse clinical applications is warranted.
