Readers ask: Why Would A Patient Need To Add Insulin To Their Regimen Along With An Oral Agent For Diabetes?

What are the advantages of adding insulin to existing therapies with oral agents?

Hypoglycaemia and weight gain are the most common and well known side effects of insulin therapy. Adding oral agents to insulin could reduce the required insulin dose and thus decrease these insulin-related side effects.

Why are both insulin and oral hypoglycemics prescribed?

The rationale for combining insulin and oral drug therapy derives from a better understanding of the pathophysiology of NIDDM and of the mechanisms of action of the oral drugs available: 1) type 2 diabetic patients are both insulin-deficient and insulin-resistant, thus requiring quite high doses of exogenous insulin; 2

What oral hypoglycemic agents can be used with insulin?

For these reasons, metformin has been the most commonly used drug in combination with insulin. There are few limitations for the use of metformin, the most common of which include intolerance to its gastrointestinal side effects and its contraindication in renal or hepatic insufficiency (Ahmed and Goldstein 2006).

Can oral antidiabetics be used with insulin?

A substantial body of evidence indicates that combination therapy with insulin and oral antidiabetic agents can safely establish excellent glycemic control in most patients, while it reduces the required dosage of insulin and, in some combinations, mitigates the weight gain associated with insulin therapy.

When should I switch from insulin to oral?

Typically, a physician and patient will consider such a change when there has been considerable improvement in a patient’s status and it appears that oral agents would be sufficient to maintain excellent glycemic control.

When are oral hypoglycemic agents used?

Oral hypoglycemic drugs are used only in the treatment of type 2 diabetes which is a disorder involving resistance to secreted insulin. Type 1 diabetes involves a lack of insulin and requires insulin for treatment.

Why do hospitals not give metformin?

Use of oral diabetes medications, particularly metformin, in hospitalized patients is controversial. Multiple guidelines recommend stopping these medications at admission because of inpatient factors that can increase the risk of renal or hepatic failure.

What are the classes of oral hypoglycemic agents?

Currently, there are five distinct classes of hypoglycemic agents available, each class displaying unique pharmacologic properties. These classes are the sulfonylureas, meglitinides, biguanides, thiazolidinediones and alpha-glucosidase inhibitors.

How do oral hypoglycemic medications work?

Sulfonylureas bind to adenosine triphosphate-sensitive potassium channels (K-ATP channels) in the beta cells of the pancreas; this leads to the inhibition of those channels and alters the resting membrane potential of the cell, causing an influx of calcium and the stimulation of insulin secretion.

Can you be on metformin and insulin?

Conclusions: Combination therapy with metformin and insulin improves glycemic control and reduces insulin requirements. with no major side effects, in patients with type 2 diabetes and may improve the risk profile in this patient population.

What is the action of oral hypoglycemic agents?

Oral antihyperglycemic agents lower glucose levels in the blood. They are commonly used in the treatment of diabetes mellitus.

Is insulin the preferred treatment for HbA1c 9 %?

The algorithms and guidelines of the American Association of Clinical Endocrinologists and the American Diabetes Association recommend that insulin administration be strongly considered for people with type 2 diabetes (T2D) with HbA1c levels exceeding 9.0% and 10%, respectively.

What does insulin do to your blood sugar?

The pancreas responds by producing insulin, which allows glucose to enter the body’s cells to provide energy. Store excess glucose for energy. After you eat — when insulin levels are high — excess glucose is stored in the liver in the form of glycogen.

Can you take sulfonylureas and insulin?

Combining insulin and sulfonylurea is usually not endorsed, as they have similar mechanisms of action (providing more insulin) and the same glucose-lowering effect can usually be achieved with a modestly higher dose of insulin alone.

Is insulin an antidiabetic drug?

Antidiabetic drugs are medicines developed to stabilise and control blood glucose levels amongst people with diabetes. Antidiabetic drugs are commonly used to manage diabetes. There are a number of different types of antidiabetic drug including: Insulin.
