⚡ Quick Answer — What is Ziten?
Ziten είναι μια μάρκα teneligliptin (20 mg), a DPP-4 inhibitor (dipeptidyl peptidase-4 inhibitor, also called a “gliptin”) used for type 2 diabetes. It works by blocking the enzyme DPP-4, which normally breaks down incretin hormones (GLP-1 and GIP). Higher incretin levels stimulate insulin release and suppress glucagon only when blood glucose is high — so DPP-4 inhibitors produce a glucose-dependent effect and do not cause hypoglycaemia as monotherapy. HbA1c reduction: 0.6–0.8 points. Weight-neutral. Once-daily dosing (most gliptins). Low-cost gliptin widely available in India and other Asian markets; 24-hour once-daily coverage at a small dose. Limited large outcome-trial data compared with sitagliptin or linagliptin — Japanese post-marketing surveillance is reassuring. Dose: 20 mg once daily; can be doubled to 40 mg/day if glycaemic control is inadequate. Main side effects are mild — upper respiratory symptoms, headache, rare pancreatitis. Avoid in type 1 diabetes and DKA.

What Is Ziten?
Ziten is an oral antidiabetic medicine containing teneligliptin (20 mg), manufactured by Glenmark Pharmaceuticals. Available in packs of 30, 60, 90 or 180 tablets. It is prescribed for adults with type 2 diabetes, usually alongside metformin or as a second- or third-line agent.
teneligliptin belongs to the DPP-4 inhibitor (“gliptin”) class — first approved 2012 in Japan, later in India and other Asian markets (not approved in US/EU). Gliptins are widely used because they are weight-neutral, have a low hypoglycaemia risk, and can be used across the renal spectrum with appropriate dose adjustment.
How Does Ziten Work?
After meals, the gut releases two incretin hormones — GLP-1 (glucagon-like peptide-1) και GIP (glucose-dependent insulinotropic peptide). These hormones tell the pancreas to release insulin and the liver to suppress glucagon, but they are rapidly broken down by the enzyme dipeptidyl peptidase-4 (DPP-4) within minutes.
teneligliptin blocks DPP-4. This raises active GLP-1 and GIP levels, producing:
- Glucose-dependent insulin release from pancreatic beta cells — only when blood glucose is elevated
- Suppression of glucagon from alpha cells, reducing hepatic glucose output after meals
- Modest slowing of gastric emptying
Because insulin release is glucose-dependent, DPP-4 inhibitors do not cause hypoglycaemia on their own. Typical HbA1c reduction: 0.6–0.8 percentage points. Weight effect: neutral. Blood pressure and lipid effects: neutral.
Δοσολογία και Χορήγηση
Τυπική δόση: 20 mg once daily; can be doubled to 40 mg/day if glycaemic control is inadequate. Ziten can be taken with or without food.
- Once-daily dosing (twice for vildagliptin) — pick a consistent time.
- Half-life and excretion: ~24 hours; mixed hepatic/renal elimination.
- Renal dosing: No dose adjustment in mild-to-moderate renal impairment. Avoid in severe renal impairment unless monitored.
- No hepatic dose adjustment for most gliptins (vildagliptin needs baseline ALT check).
- Miss a dose — skip it; take the next at the usual time. Do not double up.
Παρενέργειες
DPP-4 inhibitors are among the best-tolerated oral antidiabetics. Most side effects are mild and similar across the class.
Συχνές:
- Upper respiratory tract infection, nasopharyngitis
- Κεφαλαλγία
- Mild GI upset — nausea, diarrhoea (less common than with metformin)
Uncommon but important:
- Acute pancreatitis — rare but documented class effect; stop immediately if severe abdominal pain develops
- Severe joint pain (arthralgia) — can occur weeks to months after starting; usually resolves on discontinuation
- Hypersensitivity / angioedema — bullous pemphigoid has been reported; stop if blistering skin lesions develop
- Saxagliptin specifically: small increase in hospitalisation for heart failure
- Vildagliptin specifically: rare hepatic enzyme elevations — monitor ALT
As monotherapy, hypoglycaemia is very rare. When combined with sulfonylureas or insulin, those agents’ doses may need reducing.
Αλληλεπιδράσεις Φαρμάκων
- Sulfonylureas, insulin, meglitinides — additive glucose-lowering. Expect to reduce these doses when adding a gliptin.
- Strong CYP3A4/5 inhibitors (ketoconazole, clarithromycin, ritonavir, atazanavir) — raise saxagliptin levels; halve the saxagliptin dose. Minimal effect on sitagliptin, linagliptin, vildagliptin.
- Rifampicin — reduces linagliptin levels modestly; effect may be clinically meaningful.
- Αναστολείς ACE — theoretical additive angioedema risk; clinical significance debated.
- Ντιγκοξίνη — small rise in peak level with sitagliptin; usually not clinically important.
Who Should Not Take Ziten?
- Type 1 diabetes mellitus
- Diabetic ketoacidosis
- Known hypersensitivity to teneligliptin or other DPP-4 inhibitors
- History of pancreatitis (relative — discuss alternatives)
- Pregnancy and breastfeeding — data limited; alternatives preferred
- Saxagliptin specifically: severe heart failure
- Vildagliptin specifically: ALT or AST > 3× upper limit of normal
Αποθήκευση
Store Ziten below 30°C in a dry place, in the original blister. Keep out of reach of children.
Συχνές Ερωτήσεις
Is Ziten the same as teneligliptin?
Yes. Ziten contains the same active ingredient as the originator brand. Bioequivalence is required by regulatory authorities, so clinical effect is the same at the same dose.
Is teneligliptin as effective as sitagliptin?
Head-to-head trials and meta-analyses suggest teneligliptin produces similar HbA1c reduction (0.6–0.9 points) to sitagliptin, with a similar safety profile. Long-term cardiovascular outcome data are more limited than for sitagliptin or linagliptin, and it is not approved in the US or EU.
Will Ziten cause low blood sugar?
On its own, no. DPP-4 inhibitors act in a glucose-dependent manner — they only augment insulin release when blood glucose is high. Hypoglycaemia only becomes a concern when Ziten is combined with a sulfonylurea, meglitinide, or insulin.
Does Ziten cause weight gain?
No — DPP-4 inhibitors are weight-neutral. This is one of the main reasons they are preferred over sulfonylureas in overweight patients.
Can Ziten cause pancreatitis?
Acute pancreatitis is a rare but documented class effect. The absolute risk is small, and large trials (TECOS, CARMELINA, SAVOR) have generally shown no statistically significant excess. Stop immediately and seek medical attention if severe abdominal pain develops — especially pain radiating to the back.
How long does Ziten take to work?
Fasting glucose starts to fall in the first week. Maximal HbA1c effect is at 12 weeks. If HbA1c has not fallen by at least 0.3–0.5% after 3 months, a different second agent (SGLT-2 inhibitor or GLP-1 agonist) should be considered.
Can I stop Ziten suddenly if I don’t feel well?
Yes — DPP-4 inhibitors can be stopped abruptly without rebound hyperglycaemia. If you develop severe abdominal pain, skin blistering, or severe joint pain, stop and contact your doctor.
Where can I buy Ziten online?
