Teneligliptin is an oral anti-diabetic medication containing Teneligliptin, a Dipeptidyl Peptidase-4 (DPP-4) inhibitor. It is used to manage Type 2 Diabetes Mellitus (T2DM) in adults by enhancing the body's natural ability to lower blood sugar. It works by increasing insulin levels after meals and reducing the amount of sugar produced by the liver, specifically acting only when blood glucose levels are high.

Teneligliptin is a modern anti-diabetic agent belonging to the class of medications known as "gliptins." It is prescribed for adults with Type 2 Diabetes when diet and exercise alone do not provide adequate glycemic control. Teneligliptin is characterised by its unique chemical structure, which allows it to bind powerfully to the DPP-4 enzyme for a prolonged period, providing effective 24-hour blood sugar management.

The medication targets the incretin system. Incretins are hormones released by the gut that signal the pancreas to produce insulin. Usually, these hormones are broken down very quickly by an enzyme called DPP-4. By inhibiting this enzyme, Teneligliptin allows incretin hormones to stay active longer. This leads to better insulin secretion and a decrease in glucagon (a hormone that raises sugar) in a glucose-dependent manner.

One significant advantage of Teneligliptin is its "dual pathway" of elimination. It is cleared from the body by both the liver and the kidneys. This balanced clearance makes it a versatile option for patients with varying degrees of organ function. It is weight-neutral and carries a very low risk of hypoglycemia when used as a single therapy, making it a reliable choice for long-term diabetes maintenance.

Teneligliptin (Teneligliptin 20mg) is indicated for:

Type 2 Diabetes Mellitus (T2DM):

To improve glycemic control in adult patients as an adjunct to diet and exercise.

Combination Therapy:

It can be used alongside Metformin, Sulfonylureas, Thiazolidinediones, or SGLT2 inhibitors when blood sugar remains uncontrolled on those medications.

Smart Sugar Control:

It only stimulates insulin when blood sugar is high, significantly reducing the risk of sudden "crashes" or hypoglycemia.

24-Hour Efficacy:

A single dose provides stable inhibition of the DPP-4 enzyme for a full day.

Weight Neutrality:

Unlike some other diabetes medications, it does not cause weight gain.

Flexible Elimination:

The dual clearance through both liver and kidneys offers a high safety profile.

Organ Protection:

Maintaining steady glucose levels helps protect against diabetic complications like nerve damage and vision loss.

Teneligliptin is generally well-tolerated. Most side effects are mild and transient.

Common Side Effects:

• Nasopharyngitis (cold-like symptoms).

• Headache

• Gastrointestinal issues like constipation or bloating

• Skin itching or rash

Serious Side Effects (Seek urgent medical attention):

• Pancreatitis: Severe, persistent abdominal pain radiating to the back.

• Intestinal Obstruction: Severe constipation with abdominal distension.

• Severe Hypersensitivity: Swelling of the face, lips, or tongue.

• Dosage: The usual starting dose is 20mg once daily. In some cases, a doctor may increase this to 40mg.
• Administration: The tablet is taken orally, usually at the same time each day.
• With or Without Food: It can be taken regardless of meal times. Whole Tablet: Swallow the tablet whole with water; do not crush or chew it.

Teneligliptin works by inhibiting the enzyme Dipeptidyl Peptidase-4. This enzyme is responsible for degrading Incretin hormones (GLP-1 and GIP).

1. Incretin Stabilisation: By blocking DPP-4, Teneligliptin increases the concentration of active GLP-1 in the blood.
2. Insulin Modulation: This high GLP-1 level tells the pancreas to release insulin only when glucose is present.
3. Glucagon Suppression: It simultaneously tells the liver to stop producing unnecessary glucose. This result is a smooth reduction in both fasting and post-meal blood sugar levels.

• Check Your Feet: Even with modern medications, daily foot inspection is vital for diabetics.

• Consistency: Take your dose at the same time every day to keep the DPP-4 enzyme suppressed consistently.

• Monitor Pancreas Health: If you experience severe, persistent stomach pain, stop the medication and call your doctor immediately.

• Stick to the Diet: Medication is most effective when paired with the diabetic diet recommended by your nutritionist.

Store in a cool, dry place at room temperature (below 30°C). Keep away from direct sunlight and moisture. Store out of reach of children.

• Sulfonylureas/Insulin: Using Teneligliptin with these medications increases the risk of hypoglycemia.

• QT-prolonging Drugs: Medications like certain antibiotics or antipsychotics may interact with Teneligliptin’s effect on heart rhythm.

• Salicylates: High doses of aspirin may enhance the blood-sugar-lowering effect.

• Heart Failure: Use with caution, as some medications in the DPP-4 class have been linked to an increased risk of heart failure hospitalisation.

• History of Pancreatitis: Should be used with caution in patients who have previously had inflammation of the pancreas.

• Arrhythmia: Caution is advised in patients with a history of QT prolongation (a heart rhythm condition).

In case of an overdose, symptomatic and supportive treatment is required. While Teneligliptin has a high safety ceiling, an overdose should be reported to emergency services or a healthcare provider immediately for monitoring.

Take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed one. Do not take a double dose to make up for a missed tablet.
