Meglitinides or glinides are a class of drugs used to treat type 2 diabetes. [1]

Contents

Drugs

Repaglinide (trade name Prandin) [2] gained US Food and Drug Administration approval in 1997.

Other drugs in this class include nateglinide (Starlix) [3] and mitiglinide (Glufast).

Side effects

Side effects include weight gain and hypoglycemia. While the potential for hypoglycemia is less than for those on sulfonylureas,[ citation needed ] it is still a serious potential side effect that can be life-threatening. Patients on this medication should know the signs and symptoms of hypoglycemia and appropriate management.

Repaglinide caused an increased incidence in male rats of benign adenomas (tumors) of the thyroid and liver. [2] No such effect was seen with another drug of this class, nateglinide. [3]

A 2020 Cochrane systematic review did not find enough evidence of reduction of all-cause mortality, serious adverse events, cardiovascular mortality, non-fatal myocardial infarction, non-fatal stroke or end-stage renal disease when comparing metformin monotherapy to meglitinide for the treatment of type 2 diabetes. [4]

Mechanism of action

They bind to an ATP-dependent K + (KATP) channel on the cell membrane of pancreatic beta cells in a similar manner to sulfonylureas but have a weaker binding affinity and faster dissociation from the SUR1 binding site. This increases the concentration of intracellular potassium, which causes the electric potential toward the intracellular side of the membrane to become more positive. This depolarization opens voltage-gated Ca 2+ channels. The rise in intracellular calcium leads to increased fusion of insulin granula in the cell membrane, and therefore increased secretion of (pro) insulin.

<span class="mw-page-title-main">Hypoglycemia</span> Decrease in blood sugar

Hypoglycemia, also spelled hypoglycaemia or hypoglycæmia, sometimes called low blood sugar, is a fall in blood sugar to levels below normal, typically below 70 mg/dL (3.9 mmol/L). Whipple's triad is used to properly identify hypoglycemic episodes. It is defined as blood glucose below 70 mg/dL (3.9 mmol/L), symptoms associated with hypoglycemia, and resolution of symptoms when blood sugar returns to normal. Hypoglycemia may result in headache, tiredness, clumsiness, trouble talking, confusion, fast heart rate, sweating, shakiness, nervousness, hunger, loss of consciousness, seizures, or death. Symptoms typically come on quickly.

<span class="mw-page-title-main">Glimepiride</span> Medication

Glimepiride is an antidiabetic medication within the sulfonylurea class, primarily prescribed for the management of type 2 diabetes. It is regarded as a second-line option compared to metformin, due to metformin's well-established safety and efficacy. Use of glimepiride is recommended in conjunction with lifestyle modifications such as diet and exercise. It is taken by mouth, reaching a peak effect within three hours and lasting for about a day.

<span class="mw-page-title-main">Metformin</span> Medication used to treat diabetes

Metformin, sold under the brand name Glucophage, among others, is the main first-line medication for the treatment of Type 2 diabetes, particularly in people who are overweight. It is also used in the treatment of polycystic ovary syndrome, and is sometimes used as an off-label adjunct to lessen the risk of metabolic syndrome in people who take antipsychotic medication. It has been shown to inhibit inflammation, and is not associated with weight gain. Metformin is taken by mouth.

Drugs used in diabetes treat diabetes mellitus by decreasing glucose levels in the blood. With the exception of insulin, most GLP-1 receptor agonists, and pramlintide, all diabetes medications are administered orally and are thus called oral hypoglycemic agents or oral antihyperglycemic agents. There are different classes of hypoglycemic drugs, and selection of the appropriate agent depends on the nature of diabetes, age, and situation of the person, as well as other patient factors.

<span class="mw-page-title-main">Thiazolidinedione</span> Class of chemical compounds

The thiazolidinediones, abbreviated as TZD, also known as glitazones after the prototypical drug ciglitazone, are a class of heterocyclic compounds consisting of a five-membered C3NS ring. The term usually refers to a family of drugs used in the treatment of diabetes mellitus type 2 that were introduced in the late 1990s. As of 2024, there are two FDA-approved drugs in this class, pioglitazone and rosiglitazone.

<span class="mw-page-title-main">Rosiglitazone</span> Chemical compound

Rosiglitazone is an antidiabetic drug in the thiazolidinedione class. It works as an insulin sensitizer, by binding to the PPAR in fat cells and making the cells more responsive to insulin. It is marketed by the pharmaceutical company GlaxoSmithKline (GSK) as a stand-alone drug or for use in combination with metformin or with glimepiride. First released in 1999, annual sales peaked at approximately $2.5-billion in 2006; however, following a meta-analysis in 2007 that linked the drug's use to an increased risk of heart attack, sales plummeted to just $9.5-million in 2012. The drug's patent expired in 2012.

<span class="mw-page-title-main">Pioglitazone</span> Chemical compound

Pioglitazone, sold under the brand name Actos among others, is an anti-diabetic medication used to treat type 2 diabetes. It may be used with metformin, a sulfonylurea, or insulin. Use is recommended together with exercise and diet. It is not recommended in type 1 diabetes. It is taken by mouth.

<span class="mw-page-title-main">Sulfonylurea</span> Class of organic compounds used in medicine and agriculture

Sulfonylureas or sulphonylureas are a class of organic compounds used in medicine and agriculture. The functional group consists of a sulfonyl group (-S(=O)2) with its sulphur atom bonded to a nitrogen atom of a ureylene group (N,N-dehydrourea, a dehydrogenated derivative of urea). The side chains R1 and R2 distinguish various sulfonylureas. Sulfonylureas are the most widely used herbicide.
