Description

Sita-Met XR 100/1000mg Tablet is a maximum-strength, extended-release combination medicine formulated for adults with type 2 diabetes mellitus who require the full standard adult dose of both Sitagliptin and Metformin in a single once-daily tablet. Unlike lower-strength combinations that pair a reduced 50mg Sitagliptin dose with varying Metformin amounts, this formulation delivers the complete 100mg Sitagliptin dose, which is generally reserved for patients with normal kidney function who need the strongest available incretin-based effect alongside a high, steadily released dose of Metformin. This tablet is typically prescribed for patients who have already been managed on lower combination strengths but continue to need more intensive glycemic control, or for those consolidating two previously separate higher-dose medicines into one convenient once-daily tablet. The extended-release Metformin component is designed to release gradually over several hours, helping to support consistent blood sugar control while easing the digestive impact often associated with high-dose Metformin. The pack contains 14 tablets, generally supporting a two-week course, and this medicine should only be started or adjusted under close medical supervision.

Ingredients

Each Sita-Met XR 100/1000mg Tablet contains Sitagliptin 100mg combined with Metformin Hydrochloride 1000mg in extended-release form. The full-strength Sitagliptin dose works by prolonging the activity of the body’s incretin hormones, promoting insulin release in a glucose-dependent manner and suppressing excess glucose production by the liver, while the high-dose extended-release Metformin component is contained within a controlled-release matrix, commonly built using hydroxypropyl methylcellulose, that governs the gradual dissolution and absorption of the medicine. Additional inactive ingredients typically include microcrystalline cellulose, magnesium stearate, colloidal silicon dioxide, and a film coating that supports the tablet’s structural integrity and ease of swallowing.

Dosage Form

This medicine is manufactured as a large, film-coated extended-release oral tablet, engineered with a controlled-release matrix capable of accommodating both the full Sitagliptin dose and the high Metformin content while maintaining a gradual absorption profile. The tablets are supplied in blister strips that protect them from moisture and light, helping preserve the release mechanism’s integrity until the expiry date noted on the packaging.

Uses

Sita-Met XR 100/1000mg Tablet is used for the management of type 2 diabetes mellitus in adults who require the maximum standard combination dose to achieve adequate blood sugar control. The full 100mg Sitagliptin dose provides the strongest incretin-based support available in this combination series, enhancing insulin secretion after meals and limiting unnecessary hepatic glucose release, while the high-dose extended-release Metformin component further reduces liver glucose production and improves insulin sensitivity in muscle and fat tissue over a sustained period. This tablet is often prescribed for patients who have progressed through lower combination strengths without reaching their glycemic targets, or those who need to simplify a more complex medication regimen into a single once-daily tablet. As with other therapies in this class, it is generally used alongside a structured diet, regular physical activity, and consistent monitoring to support long-term diabetes management and help reduce the risk of related complications.

How to Use

Sita-Met XR 100/1000mg Tablet should be taken exactly as directed by the prescribing doctor, typically once daily with the evening meal to support gradual and consistent absorption overnight. The tablet must always be swallowed whole with a sufficient amount of water and should never be crushed, split, or chewed, since doing so could disrupt the extended-release mechanism and cause the medicine to be released more quickly than intended, raising the risk of side effects. Because this is the maximum-strength combination in the series, doctors typically prescribe it only after confirming that the patient tolerates lower doses of both components well. Patients may occasionally notice a tablet-shaped residue in their stool, which is simply the emptied shell of the release matrix and is a normal, harmless occurrence. A missed dose should be taken as soon as it is remembered, but if the next dose is close, the missed one should be skipped rather than taking a double dose.

Side Effects

Given that this tablet contains the full strength of both active ingredients, side effects from either component may be more noticeable, particularly when treatment is first started. Gastrointestinal effects such as nausea, diarrhea, bloating, or a metallic taste are commonly associated with the Metformin component and often ease with continued use. Effects linked to the higher Sitagliptin dose may include headache, upper respiratory tract infection, or sore throat. Some patients may also experience mild joint discomfort or reduced appetite. In rare but serious cases, symptoms of lactic acidosis (such as unusual muscle pain, rapid or difficult breathing, or unexplained fatigue), pancreatitis, or allergic reactions such as rash, facial swelling, or breathing difficulty may occur and require urgent medical attention. Any severe, persistent, or unusual symptoms should be promptly discussed with a healthcare provider.

Pregnancy & Breastfeeding

Sita-Met XR 100/1000mg Tablet is generally not recommended during pregnancy unless a physician determines that the treatment benefit clearly outweighs any potential risk, as diabetes management in pregnancy is typically handled through alternative protocols better suited to that stage. Women who are pregnant, planning a pregnancy, or currently breastfeeding should inform their doctor before starting or continuing this medicine so that safer treatment options can be considered if necessary. Since both active ingredients may pass into breast milk to some extent, breastfeeding mothers should seek individualized medical advice before use.

Storage Instructions

Store Sita-Met XR 100/1000mg Tablets in a cool, dry place away from direct sunlight, excessive heat, and moisture, ideally at a temperature below 30°C. Keep the tablets in their original blister packaging until they are ready to be used, to help protect the extended-release coating, and store them securely out of the reach and sight of children and pets. Avoid storing this medicine in bathrooms or other humid areas, and never allow the tablets to freeze. Always check the expiry date before use, and dispose of any expired or unused tablets responsibly through an appropriate medicine disposal program rather than household waste or drains.

FAQS

Q1. How is this combination different from the 50/1000mg XR strength?
This tablet delivers the full 100mg Sitagliptin dose rather than 50mg, making it the maximum-strength option in the combination series for patients who need stronger incretin-based support.

Q2. Is this tablet suitable for patients with reduced kidney function?
The full 100mg Sitagliptin dose combined with high-dose Metformin generally requires normal kidney function, so a doctor will assess renal health carefully before prescribing this strength.

Q3. Can this tablet replace two separate medicines a patient is already taking?
In some cases, doctors may consolidate a patient’s existing Sitagliptin and Metformin doses into this single tablet for convenience, but only after confirming the doses match appropriately.

Q4. Does the extended-release format still apply at this higher combined strength?
Yes, the Metformin component remains in extended-release form, supporting gradual absorption and once-daily dosing even at this maximum strength.

Q5. What monitoring is typically needed while on this medicine?
Doctors generally recommend periodic kidney function tests and regular blood sugar monitoring to ensure the medicine continues to be both safe and effective.
