Summary
High-dose metformin effectively improved glycemic control in both elderly and younger patients with type 2 diabetes. This study found metformin safe for older adults, with no adverse events or hypoglycemia observed.
Area of Science:
- Endocrinology
- Geriatrics
- Pharmacology
Background:
- High-dose metformin is now available for type 2 diabetes management in Japan.
- Elderly patients with type 2 diabetes require careful consideration for medication safety and efficacy.
Purpose of the Study:
- To evaluate the efficacy and safety of high-dose metformin in elderly type 2 diabetes patients.
- To compare glycemic control and adverse events between elderly and younger metformin users.
Main Methods:
- Retrospective study of 98 type 2 diabetes patients treated with metformin.
- Patients divided into two groups: younger (<65 years) and elderly (≥65 years).
- Primary endpoint: change in glycosylated hemoglobin A1c (HbA1c) at 12 weeks; secondary endpoints: safety variables.
Main Results:
- Significant HbA1c reduction observed in both groups (Group I: -0.5%, Group II: -0.9%).
- No significant difference in HbA1c change between elderly and younger patients.
- No hypoglycemic events or adverse events reported in either group.
Conclusions:
- Metformin demonstrates comparable efficacy and safety in improving glycemic control for both elderly and younger type 2 diabetes patients.
- Further research is needed to determine optimal metformin dosage and appropriate serum creatinine (Cre) and estimated glomerular filtration rate (eGFR) levels for elderly patients.

01:26Oral Hypoglycemic Agents: Biguanides and Glitazones
Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood glucose levels...
01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...
01:24Type II Diabetes II: Pathophysiology
PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
01:36Carbohydrate Metabolism
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...

01:22Diabetes Mellitus: Type 2 and Gestational
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
01:15Drug Dosing: Geriatric Patients
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
