The glibenclamide is an oral antidiabetic belonging to the group of the sulfonylureas, drug chemical structure that releases insulin pancreas to mobilize sugar the bloodstream to cells of the body, to achieve lower levels of the same blood.

This medicine is used to treat diabetes in cases when the disease cannot be controlled normally with diet and exercise, and also when it is not necessary to use insulin.

Glibenclamide benefits

It is a drug that is used to control blood sugar levels for the suffering of type 2 diabetes. This disease has the characteristic of not being dependent on insulin, which makes it more common among overweight adults and in currently there is a high rate of young people affected by poor diet.

It has the ability to block ATP-dependent potassium channels found in the membranes of pancreatic beta cells, this allows depolarization, adequate calcium entry, insulin release, and decreased levels of liver glycogenolysis. and gluconeogenesis.

This drug is indicated to improve this disease and give benefit to the body, in that case we mention:

  • It is prescribed to control blood sugar levels when diets are not enough to control weight.
  • It has a hypoglycemic effect by stimulating the release of insulin through the beta cells of the pancreas, according to the intake by glucose measurement.
  • It stabilizes the output of potassium to produce the depolarization of the membrane and manages to activate the calcium channels so that they increase in the intracellular levels and thus be able to stimulate the secretion of insulin.
  • It reduces the production of hepatic glucose.
  • It enhances the action of insulin levels in peripheral tissues , especially in muscle and adipose tissue.
  • Allows diuretic levels to kick in slightly to increase fluid clearance.

How does glibenclamide work in the body?

The suffering of type 2 diabetes is due to the deficiency of insulin, a hormone that is produced by the pancreas and is responsible for controlling blood sugar levels to allow the body’s cells to reduce its excess in the torrent blood.

Insulin is produced inefficiently due to rises in blood sugar levels in this type of diabetes. Likewise, the body’s cells are resistant to the action of the hormone produced by the pancreas, which leads to an excessive rise in sugar levels.

By taking this medicine, the beta cells of the pancreas, which produce insulin, are stimulated. The production of this hormone helps reduce high blood sugar levels in the case of type 2 diabetes.

It can also work as an excellent option to treat diabetes of this type, in patients who are not overweight.

How to take glibenclamide?

The consumption of this medicine must be respected, as prescribed by the treating doctor, since its ingestion in the wrong way can cause powerful risks to the body and blood sugar levels can get out of control.

Glibenclamide Tablets

  • The starting dose should be 2.5 to 5 milligrams once a day.
  • Then the doctor will determine if a dose adjustment is necessary to increase it or change it to an intake 2 times a day according to the sugar levels you have.

Glibenclamide micronized tablets

  • It should start with a dose of 1.5 to 3 milligrams 1 time per day.
  • If your doctor thinks it is necessary based on your blood sugar levels, the dose may change each week to 1.5 milligrams a day.

During the gestation or lactation period, some medications should not be used, since it is a delicate stage for both the mother and the baby. However, the doctor is the one who can determine the need to take it considering the benefits and risks that they can cause.

If you suffer from diabetes during pregnancy, you should control glucose with a balanced diet, otherwise you would have to undergo a control with insulin and a strict diet.

Oral antidiabetics pass through the placenta and can stimulate the production of insulin in the fetus, causing hypoglycemia at birth. In case of having to take it by medical prescription, it is recommended to suspend it at least one week before delivery to avoid this condition in the newborn.

By passing into breast milk there is a risk of a decrease in glucose levels in the infant’s blood, therefore, it is advisable to avoid its administration during this period.
