Introduction About ISTAVEL 50MG TABLET
What is ISTAVEL 50mg Tablet?
ISTAVEL 50mg Tablet supports the management of blood sugar levels by enhancing the body's natural insulin response after meals and reducing excess sugar production by the liver. It belongs to a class of medicines called DPP-4 inhibitors that help regulate glucose levels in adults with type 2 diabetes mellitus.
Inform your doctor about existing medical conditions before using ISTAVEL 50mg Tablet. It is not recommended for individuals under 18 years of age. Do not exceed the prescribed dose or discontinue medication without consulting your doctor. Report any unusual symptoms or side effects to your healthcare provider promptly.
It is important to limit alcohol consumption while on ISTAVEL 50mg Tablet, as it can increase the risk of low blood sugar. You may need regular tests, such as kidney function and blood glucose levels, to ensure the medication is working effectively.
Effective glycemic management with ISTAVEL 50mg Tablet works best when combined with a balanced diet, regular exercise, and regular medical check-ups. This approach helps maintain overall metabolic health and supports a better quality of life.
The possible side effects are headache, nausea, or muscle discomfort. Serious side effects are rare but should be reported to a healthcare professional immediately.

How ISTAVEL 50mg Tablet Supports Blood Sugar Control
- ISTAVEL 50mg Tablet supports blood sugar control primarily through the active ingredient Sitagliptin, which belongs to a class of drugs called dipeptidyl peptidase-4 (DPP-4) inhibitors
- By preserving the action of incretin hormones, ISTAVEL enhances insulin release when blood sugar levels are elevated and manages unnecessary insulin secretion when blood sugar is normal or low, thereby minimizing the risk of hypoglycemia
How ISTAVEL 50MG TABLET Works
- ISTAVEL 50mg Tablet works in the body primarily by inhibiting the enzyme dipeptidyl peptidase-4 (DPP-4), which is responsible for breaking down incretin hormones such as GLP-1 (glucagon-like peptide-1) and GIP (gastric inhibitory peptide)
- By blocking DPP-4, ISTAVEL helps increase and prolong the action of incretins, resulting in higher insulin levels when blood sugar is elevated after meals, and reducing glucagon secretion to limit unnecessary glucose release from the liver. This glucose-dependent mechanism ensures that insulin is released primarily when needed, minimizing the risk of hypoglycemia
- ISTAVEL supports better insulin sensitivity in muscle and fat cells, improving glucose uptake and utilization by the body. Through these combined effects enhanced insulin secretion, decreased glucagon production, and improved peripheral glucose use
- ISTAVEL 50mg helps maintain more stable blood sugar levels throughout the day in people with type 2 diabetes
- Overall, ISTAVEL’s mechanism facilitates natural hormonal regulation of glucose metabolism, complementing lifestyle measures to support effective blood sugar control
Mechanism of ISTAVEL: Fasting vs. Postprandial Effects
- ISTAVEL 50mg Tablet (Sitagliptin) exhibits a dual mechanism of action that helps regulate blood sugar levels during both fasting and postprandial (after meal) states. During fasting periods, such as overnight or between meals, ISTAVEL reduces excessive glucose production by the liver by inhibiting the release of glucagon, a hormone that raises blood sugar. This action helps manage elevated blood glucose levels when the body is at rest
- Postprandially, after eating, ISTAVEL works by enhancing the levels of incretin hormones like GLP-1 (glucagon-like peptide-1) and GIP (gastric inhibitory peptide) which are naturally released in response to food intake. These hormones stimulate the pancreas to secrete insulin in a glucose-dependent manner. At the same time, ISTAVEL suppresses glucagon secretion, reducing unnecessary glucose release from the liver during this period
- By preserving incretin hormone activity through the inhibition of the DPP-4 enzyme, ISTAVEL supports a balanced insulin and glucagon response tailored to blood glucose levels throughout the day. This mechanism acts to lower both fasting and post-meal blood sugar without causing excessive insulin secretion or hypoglycemia. The combined fasting and postprandial effects support stable glycemic control, crucial for managing type 2 diabetes effectively
- Overall, ISTAVEL’s mode of action enhances the body’s natural glucose regulatory processes, maintains blood sugar within a healthier range, and complements lifestyle measures like diet and exercise to promote metabolic balance
