Istavel 25mg (Sitagliptin)

Overview

Istavel 25mg is a generic version of Sitagliptin, which is an agent used to maintain blood sugar levels in individuals suffering from type 2 diabetes mellitus (T2DM). Sitagliptin belongs to a category of medications known as DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors).

It’s usually used together with other medications for diabetes that include metformin, sulfonylureas as well as insulin when the other medications are not sufficient for blood sugar management. Sitagliptin is not a cause of weight increase and comes with an extremely low risk of developing low blood sugar (low glucose levels) even when taken on its own.

Composition

• Active Ingredient: Sitagliptin monohydrate phosphate equivalent to 25 mg of base Sitagliptin
• Brand Name: Istavel
• Manufacturer: Most commonly, they are produced by Sun Pharma and other pharmaceutical corporations in various nations

Mechanism of Action

Sitagliptin functions in the same way by blocking the enzyme DPP-4 that breaks down the hormone incretin (like GLP-1, and GIP) within the body. Incretins are helpful in:

• Increase insulin production through the pancreas’s reaction to food
• Suppresses the release of glucagon and lowers glucose production in the liver

In addition, by enhancing the effects of incretin, Sitagliptin can help decrease postprandial as well as fasting blood sugar levels.

Indications and Uses

Istavel 25mg is used to treat:

• Type 2 diabetes mellitus (T2DM) in adults:
  • For monotherapy for those times when exercise and diet are not sufficient for Glycemic control, metformin isn’t appropriate
  • As add-on therapy to:
    • Metformin
    • Sulfonylureas (like glimepiride)
    • Thiazolidinediones
    • Insulin (with or without metformin)

Sitagliptin is not recommended for patients with Type 1 Diabetes or diabetic ketoacidosis.

Dosage and Administration

Standard Dosage:

• The typical dosage for Sitagliptin will be 100 mg per day
• Istavel 25mg is normally prescribed for those suffering from moderate or extreme renal impairment

Renal Impairment Dosage Adjustments:

Doses are to be taken at least once a day, either with or without food.

Benefits of Sitagliptin (Istavel)

• Enhances the HbA1c (average blood sugar) by ~0.6-0.8%
• Hypoglycemia is not a risk, particularly when using insulin or Sulfonylureas
• Weight-neutral is not a cause of the growth of weight
• Simple oral dosing once a day
• It is well-tolerated by the majority of patients

Side Effects

Common Side Effects:

• Nasopharyngitis (sore throat, runny nose)
• Headache
• Upper respiratory tract infections
• Stomach discomfort or gas

Less Common but Serious Side Effects:

• Pancreatitis (uncommon, but very serious acute pancreas inflammation)
  • Symptoms: severe abdominal pain, nausea, vomiting
• Hypoglycemia (particularly when it is particularly when)
• Allergic reactions (rash, swelling, breathing difficulty)
• Joint pain (can be severe in rare cases)
• Kidney function changes (rare)

If serious adverse side effects develop, the medication must be stopped immediately, and medical attention is required.

Contraindications

Don’t take Istavel 25mg for patients who suffer from:

• Type 1 diabetes mellitus
• Diabetic ketoacidosis
• Hypersensitivity is known to Sitagliptin, or any of its components
• A history of severe allergic reaction in response to DPP-4 inhibitors

Precautions and Warnings

Use with Caution in:

• Retinal impairment – Adjust doses in accordance with the kidney’s function
• History of pancreatitis
• In the same session, insulin or monitor for the presence of hypoglycemia
• Patients with a long-term illness are monitored for the kidney’s function frequently

Monitoring:

• HbA1c every 3 to 6 months to determine the control of blood sugar
• Renal function (eGFR) in the initial phase, as well as periodically
• The signs of pancreatitis and allergic reactions, or joint discomfort

Drug Interactions

Sitagliptin generally has a very low chance of drug-drug interactions. However:

Potential Interactions:

• Digoxin – Sitagliptin can elevate blood levels. Be sure to watch for any digoxin-related toxicity
• Sulfonylureas or insulin – A higher risk of developing hypoglycemia when combined

There are no major interactions with metformin and statins, ACE inhibitors, or any of the popular medicines.

Use in Pregnancy and Lactation

• Pregnancy: Sitagliptin has been classified Pregnancy category B (animal research shows that there is no harm; however, human studies have not been conducted). Utilize only when necessary.
• Lactation: It’s unknown how Sitagliptin is absorbed into the breast milk. Use only when breastfeeding, unless a doctor has advised.

Use in Older Adults

Sitagliptin is extremely well-liked by older patients. However:

• It is important to monitor the function of your kidneys frequently, since kidney function diminishes with time.
• Dosage adjustments may be required in accordance with an eGFR.

Comparison with Other Antidiabetic Drugs

Sitagliptin is typically used when patients aren’t able to tolerate metformin or require an additional drug that has minimal adverse consequences.

Storage and Handling

• Store at room temperature (15°C to 30°C / 59°F to 86°F)
• Guard against the sun and water
• Be sure to keep it out of the Children’s reach

Summary

Istavel 25mg (Sitagliptin) is a DPP-4 inhibitor that is used for the treatment of type 2 diabetes, specifically in patients who suffer from kidney problems needing a smaller dosage. It does this by stimulating incretin hormones and the release of insulin, while cutting down on the production of liver glucose. It’s easily tolerated, it offers a lower risk of hypoglycemia as well as being weight-neutral.

Key Takeaways:

• It is used to treat the treatment of type 2 diabetes, usually in combination treatments
• Dose adjustments based on the kidney’s function
• Risk of side effects is low, but be sure to look out for pancreatitis as well as hypoglycemia when using insulin
• Taken either with or without food
• Convenient once-daily dosing
