Metformin Hydrochloride丨CAS 1115-70-4

Metformin hydrochloride丨1115-70-4 is a widely prescribed medication used primarily for the treatment of type 2 diabetes mellitus. It belongs to the class of biguanides and works by improving insulin sensitivity, decreasing glucose production in the liver, and enhancing glucose uptake in muscles, which helps regulate blood sugar levels. It is often considered the first-line treatment for managing type 2 diabetes due to its effectiveness, relatively low cost, and favorable side effect profile.

1. Management of Type 2 Diabetes
Metformin hydrochloride丨1115-70-4 is most commonly used to manage type 2 diabetes (T2D), a condition in which the body either becomes resistant to insulin or does not produce enough insulin to maintain normal blood sugar levels.
● Insulin Sensitization: Metformin works by increasing the sensitivity of muscle cells to insulin, allowing the body to use insulin more efficiently. This reduces the need for high amounts of insulin to control blood sugar.
● Decreased Hepatic Glucose Production: One of metformin's primary actions is reducing glucose production in the liver (hepatic gluconeogenesis). In people with T2D, the liver often produces excessive glucose, contributing to high blood sugar. By inhibiting this process, metformin helps reduce blood glucose levels.
● Improved Glucose Uptake: Metformin enhances glucose uptake in peripheral tissues, such as muscles, which helps lower blood glucose levels post-meal.
● Weight Management: Unlike some other diabetes medications, metformin is generally weight-neutral or may even lead to slight weight loss. This is beneficial for many type 2 diabetes patients, as obesity is a common comorbidity of T2D.
● Reduction in HbA1c: Metformin can help lower HbA1c levels (a marker of long-term blood sugar control) by an average of 1-2%. This makes it a key drug in diabetes management protocols.
2. Polycystic Ovary Syndrome (PCOS)
Metformin hydrochloride丨1115-70-4 is sometimes prescribed to women with polycystic ovary syndrome (PCOS), a condition that is often associated with insulin resistance and irregular menstrual cycles.
● Regulating Menstrual Cycles: By improving insulin sensitivity, metformin can help regulate menstrual cycles and restore ovulation in women with PCOS, which may enhance fertility in some cases.
● Improving Metabolic Parameters: Metformin can also help reduce insulin levels and blood sugar in women with PCOS, potentially lowering the risk of developing type 2 diabetes, which is more common in individuals with PCOS.
● Weight Management: Metformin hydrochloride丨1115-70-4 may also help with weight loss in women with PCOS, especially those with insulin resistance, although the effects are generally modest.
3. Cardiovascular Benefits
In addition to its effects on glucose metabolism, metformin has been shown to have cardiovascular benefits for patients with diabetes.
● Reduction in Cardiovascular Risk: Metformin has been linked to a reduction in the risk of cardiovascular events such as heart attacks, strokes, and cardiovascular-related mortality in people with diabetes. This is significant because individuals with type 2 diabetes are at a higher risk for heart disease.
● Improved Lipid Profile: Metformin can help reduce levels of LDL cholesterol ("bad" cholesterol) and triglycerides while modestly increasing HDL cholesterol ("good" cholesterol), which may improve overall heart health.
4. Cancer Risk Reduction
Some studies suggest that metformin may have a potential role in cancer prevention or treatment, particularly for cancers related to insulin resistance, such as breast, prostate, and colorectal cancers.
● Insulin and Growth Factor Modulation: Metformin hydrochloride丨1115-70-4 may reduce insulin levels in the bloodstream, which in turn could lower the stimulation of insulin-like growth factors (IGF), a group of proteins involved in cancer cell proliferation.
● Cellular Mechanisms: Metformin has been shown to activate the AMPK pathway (AMP-activated protein kinase), which may inhibit cancer cell growth and promote autophagy (the process of removing damaged cells).
While these findings are promising, further research is needed to confirm the exact role of metformin in cancer prevention or treatment.
5. Potential Use in Aging
Metformin has garnered attention for its potential as a longevity or anti-aging drug. Some researchers believe that metformin's ability to improve insulin sensitivity and activate metabolic pathways (such as AMPK) might help extend lifespan and reduce age-related diseases.
● Age-Related Diseases: By reducing inflammation, improving metabolic function, and possibly limiting cellular damage, metformin may help mitigate some aspects of aging, such as cognitive decline, cardiovascular disease, and frailty. However, more clinical studies are needed to fully understand these effects.
6. Fatty Liver Disease (NAFLD/NASH)
Non-alcoholic fatty liver disease (NAFLD) and its more severe form, non-alcoholic steatohepatitis (NASH), are common conditions that often coexist with type 2 diabetes and obesity. Metformin has shown some promise in treating NAFLD/NASH, although it is not yet a standard therapy for these conditions.
● Liver Fat Reduction: Metformin's ability to reduce insulin resistance and hepatic glucose production can contribute to the reduction of liver fat in individuals with NAFLD.
● Inflammation Reduction: By activating AMPK, Metformin hydrochloride丨1115-70-4 may also help reduce inflammation in the liver, which is crucial in managing NASH and preventing progression to cirrhosis.
7. Mechanism of Action
Metformin hydrochloride丨1115-70-4 primarily works by:
1.Inhibiting Hepatic Gluconeogenesis: Metformin reduces the production of glucose in the liver, particularly by inhibiting the enzyme AMPK (AMP-activated protein kinase) pathway.
2.Improving Insulin Sensitivity: Metformin increases the sensitivity of muscle and fat cells to insulin, facilitating glucose uptake and utilization by these tissues.
3.Enhancing Glucose Utilization: It may also increase peripheral glucose uptake and utilization by muscle cells, further helping to lower blood glucose levels.
4.Modulation of Gut Microbiota: There is growing evidence that metformin may also affect the gut microbiome, which could influence its glucose-lowering effects. However, this is an area still under investigation.
8. Dosage and Administration
Metformin hydrochloride丨1115-70-4 is typically taken orally in the form of tablets or extended-release (ER) formulations.
● Standard Dosage: The usual starting dose is 500 mg once or twice daily, with meals to reduce gastrointestinal side effects. The dose is gradually increased over time, up to a maximum of 2,000–2,500 mg per day (divided into multiple doses).
● Extended-Release Formulation: The extended-release (ER) form allows for once-daily dosing, typically starting at 500 mg to 1,000 mg daily with the evening meal. The dose may be increased up to 2,000–2,500 mg per day, depending on individual tolerance and glycemic control.

Metformin hydrochloride丨1115-70-4 is a cornerstone of type 2 diabetes treatment, providing effective glucose control through improved insulin sensitivity and reduced hepatic glucose production. It is also used in managing conditions such as PCOS, fatty liver disease, and cardiovascular health. Metformin's benefits extend beyond just blood sugar control, with emerging research suggesting its potential in weight management, cancer prevention, and even longevity. While generally safe, metformin requires careful monitoring for side effects like gastrointestinal issues, vitamin B12 deficiency, and rare but serious lactic acidosis, particularly in those with kidney problems.
