Introduction
Glimepiride + Metformin is a combination of two medicines (a sulfonylurea and a biguanide) used for the treatment of type 2 diabetes mellitus (a condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood). This medicine works by lowering blood sugar levels and increasing insulin sensitivity in the body. It also helps reduce the risk of developing complications associated with diabetes.
Uses of Glimepiride + Metformin
Glimepiride + Metformin is used to treat type 2 diabetes mellitus in adults. It is a non-insulin based medication that helps lower blood sugar levels and improve insulin sensitivity. It may also be used in combination with other medicines to treat type 2 diabetes mellitus.
Mechanism of Action
Glimepiride belongs to a class of medications called sulfonylureas. It stimulates the release of insulin from the pancreas, which helps lower blood sugar levels.Metformin belongs to a class of medications called biguanides. It reduces the production of glucose in the liver and increases insulin sensitivity in the body, which helps lower blood sugar levels. When used together, Glimepiride + Metformin helps lower blood sugar levels more effectively.
How Long Does it Take to Work?
The effects of Glimepiride + Metformin can vary depending on the individual and the dosage used. Generally, Glimepiride + Metformin should take effect within 2 to 4 weeks of starting the medication. However, it may take up to 12 weeks to experience the full benefits of the medication.
Absorption
Glimepiride is rapidly absorbed from the gastrointestinal tract. Metformin is moderately absorbed from the gastrointestinal tract. Both medications are highly bioavailable, meaning that they are quickly and effectively absorbed into the bloodstream.
Route of Elimination
Glimepiride is metabolized in the liver and excreted in the urine. Metformin is excreted in the urine unchanged and also undergoes some metabolic breakdown in the liver.
Dosage
- The dosage of this tablet is governed by the desired blood glucose level. The dosage of this tablet must be the lowest which is sufficient to achieve the desired metabolic control. During treatment with this tablet glucose levels in blood and urine must be measured regularly.
- Mistakes, e.g. forgetting to take a dose, must never be corrected by subsequently taking a larger dose.
- As an improvement in control of diabetes is, in itself, associated with higher insulin sensitivity, glimepiride requirements may fall as treatment proceeds. To avoid hypoglycaemia timely dose reduction or cessation of this tablet therapy must therefore be considered.
- The highest recommended dose per day should be 8 mg of glimepiride and 2000 mg of metformin.
- In order to avoid hypoglycaemia the starting dose of this tablet should not exceed the daily doses of glimepiride or metformin already being taken.
- When switching from combination therapy of glimepiride plus metformin as separate tablets, this combination should be administered on the basis of dosage currently being taken.
The recommended starting dose is one tablet of Glimepiride + Metformin 1 mg/500 mg taken once daily with the evening meal unless otherwise directed by the physician. The dose may be increased by a maximum of two tablets per day as needed to control blood sugar levels. The maximum dosage should not exceed 8 tablets per day.
Administration
Glimepiride + Metformin should be taken once daily with the evening meal. It should be swallowed whole with water, and not crushed, split, or chewed.
