Question 1

What is Sitagliptin?

Accepted Answer

Sitagliptin is a medication that belongs to a class of drugs known as dipeptidyl peptidase-4 (DPP-4) inhibitors. It works by increasing the levels of natural substances called incretins, which help the body maintain a stable balance of sugar in the blood.

These substances signal the pancreas to release insulin and prompt the liver to reduce the amount of sugar it produces. This mechanism helps the body manage glucose levels more effectively.

Question 2

What is Sitagliptin used for?

Accepted Answer

Sitagliptin is used to treat type 2 diabetes mellitus .

Question 3

How does Sitagliptin work?

Accepted Answer

How Sitagliptin Works

Sitagliptin belongs to a class of drugs known as dipeptidyl peptidase-4 (DPP-4) inhibitors. It works by increasing the levels of natural substances called incretin hormones in the body.

The Role of Incretin Hormones

Incretin hormones are part of a system that helps the body manage blood sugar, especially after eating. Sitagliptin prevents an enzyme called DPP-4 from breaking down these hormones, allowing them to remain active in the bloodstream for a longer period. This results in two main actions:

Insulin Release: The hormones signal the pancreas to release more insulin when blood sugar levels are high. Insulin helps move sugar from the blood into the body's cells to be used for energy.

Sugar Production: The hormones signal the liver to decrease the amount of sugar it produces and releases into the blood.

Because sitagliptin works primarily when blood sugar levels are high, it helps lower blood glucose without typically causing blood sugar to drop too low when used alone. It is used to manage type 2 diabetes and is not effective for treating type 1 diabetes.

Accepted Answer

Question 8

What is the dosage of Sitagliptin and how do I take it?

Accepted Answer

How to Take Sitagliptin

Sitagliptin is available as a tablet to be taken by mouth. It is generally taken once per day and can be taken with or without food. To maintain consistent levels of the medication in your body, it is best to take it at the same time every day.

Follow the directions on your prescription label carefully and ask your healthcare provider to explain any part you do not understand. Do not take more or less of the medication than prescribed, and do not take it more frequently than directed by your doctor.

Missed Dose

If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and resume your regular dosing schedule. Do not take a double dose to make up for a missed one.

General Administration Guidelines

Swallow the tablets whole. Do not crush, chew, or break the tablets unless instructed to do so by a healthcare professional.

Continue to follow the diet and exercise plan recommended by your doctor, as sitagliptin works best when combined with these lifestyle changes.

Do not stop taking this medication without consulting your doctor, even if your blood sugar levels improve or you feel well.

Regularly monitor your blood sugar as directed by your healthcare provider to ensure the medication is working effectively.

Question 9

Is Sitagliptin safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

There is limited information regarding the safety of sitagliptin during pregnancy. While animal studies have not demonstrated a risk of birth defects or other harm to the fetus, there are no adequate and well-controlled studies in humans to confirm its safety. Maintaining stable blood sugar control is critical during pregnancy to reduce the risk of complications for both the parent and the baby.

If you are pregnant or planning to become pregnant, talk to your healthcare provider. They will evaluate whether the benefits of using sitagliptin outweigh the potential risks or if another treatment, such as insulin, is more suitable for managing blood glucose levels during this time.

Breastfeeding

It is currently unknown if sitagliptin passes into human breast milk. Research in animals has shown that the drug can be present in milk, but these findings do not always predict what happens in humans. Because many drugs are excreted in human milk, caution is advised.

Consult with a healthcare professional to weigh the benefits of breastfeeding against the potential risks to the infant while taking this medication. They can help determine the best course of action for your specific situation.

Question 10

What forms and strengths does Sitagliptin come in?

Accepted Answer

Available Forms

Combination Products

This medication is also available in combination with other active ingredients, such as metformin. These combination products are provided in the following forms:

Oral tablets

Extended-release oral tablets

Question 11

What is the FDA approval status of Sitagliptin?

Accepted Answer

FDA Approval and Indications

Sitagliptin was approved by the U.S. Food and Drug Administration (FDA) in 2006. It is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. It is not approved for use in patients with type 1 diabetes or for the treatment of diabetic ketoacidosis.

Safety Communications

The FDA has monitored and issued communications regarding several safety concerns for sitagliptin:

Pancreatitis: Postmarketing reports have identified cases of acute pancreatitis, including serious hemorrhagic or necrotizing forms. The FDA advises healthcare providers to monitor patients for persistent severe abdominal pain and to discontinue the drug if pancreatitis is suspected.

Nitrosamine Impurities: In 2022, the FDA alerted the public to the presence of a nitrosamine impurity, Nitroso-STG-19 (NTTP), in certain batches of sitagliptin. To prevent a medication shortage, the FDA permitted the temporary distribution of sitagliptin with NTTP levels above the standard intake limit while manufacturers worked to improve quality control.

Severe Joint Pain: The FDA has warned that the class of drugs known as DPP-4 inhibitors, which includes sitagliptin, may cause severe and disabling joint pain.

Heart Failure: Class-wide reviews of DPP-4 inhibitors have suggested a potential increased risk of heart failure, particularly in patients who already have heart or kidney disease.

Regulatory Status

Sitagliptin is available only by prescription. It does not currently require a Risk Evaluation and Mitigation Strategy (REMS). While sitagliptin as a single-ingredient product does not carry a boxed warning, combination products that include sitagliptin and metformin do contain a boxed warning regarding the risk of lactic acidosis.

Question 12

What should I know about Sitagliptin and weight loss?

Accepted Answer

Weight Neutrality

Sitagliptin is classified as a weight-neutral medication. Unlike some other treatments for type 2 diabetes, such as insulin or sulfonylureas, sitagliptin is not associated with weight gain in most clinical studies. It is also not considered a weight-loss drug, as it does not typically cause significant weight reduction on its own.

Factors Influencing Weight

While sitagliptin itself does not usually change a person's weight, weight changes may occur due to other factors while taking the medication:

Combination Therapy: Sitagliptin is often prescribed alongside other medications like metformin. Metformin is sometimes associated with modest weight loss, which may be observed when the two drugs are used together.

Lifestyle Changes: Patients are typically advised to follow a specific diet and exercise plan while taking sitagliptin. Any weight loss achieved is often the result of these lifestyle modifications rather than the drug itself.

Comparison to Other Drugs: Sitagliptin does not affect appetite or digestion in the same way as GLP-1 receptor agonists, which are a different class of diabetes medications known to promote weight loss.
