Keymet

Active Ingredient:: Metformin Hydrochloride
Origin:: EU

Keymet (Metformin Hydrochloride)

Q: What is Keymet used for?

Keymet contains Metformin Hydrochloride, an oral antidiabetic medication indicated for the management of type 2 diabetes mellitus. It helps lower elevated blood glucose by decreasing hepatic glucose production and improving insulin sensitivity in peripheral tissues.

Q: How does Metformin Hydrochloride work?

Metformin Hydrochloride inhibits mitochondrial complex I, reducing hepatic gluconeogenesis, and activates AMP‑activated protein kinase (AMPK). This dual action decreases glucose output from the liver and enhances glucose uptake by muscle, resulting in lower blood glucose levels.

Q: What is the usual dose of Keymet?

The dosage of Keymet is individualized by the prescribing healthcare professional based on the patient’s clinical condition, renal function, and response to therapy. The prescriber determines the appropriate strength, frequency, and titration schedule.

Q: Is Keymet safe during pregnancy or breastfeeding?

Safety of Metformin Hydrochloride in pregnancy or while breastfeeding has not been fully established. Healthcare providers should weigh potential benefits against risks and consider alternative therapies when appropriate.

Q: How do I order Keymet from GNH India?

To order Keymet, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Q: How does Keymet compare with other antidiabetic drugs?

Keymet (Metformin) belongs to the biguanide class and is often first‑line therapy for type 2 diabetes because of its efficacy, low risk of hypoglycaemia and favourable impact on weight. Compared with sulfonylureas or insulin, metformin does not stimulate insulin release and therefore carries a lower hypoglycaemia risk.

Q: What are the storage requirements for Keymet?

Keymet should be stored at room temperature, below 25 °C, in its original packaging. Protect the tablets from moisture, direct sunlight and excessive heat to maintain product stability.

Q: How is Keymet administered?

Keymet is taken orally, usually with meals to reduce gastrointestinal discomfort. The tablets are swallowed whole with a glass of water; they should not be crushed, chewed, or dissolved unless specifically instructed by a healthcare professional.

Q: What are the most serious risks associated with Keymet?

The most serious adverse reaction is lactic acidosis, a rare but potentially fatal condition that can occur in patients with significant renal or hepatic impairment, severe infection, or excessive alcohol intake. Prompt medical attention is required if symptoms such as unexplained fatigue, rapid breathing, or abdominal pain develop.

Q: Who should not use Keymet?

Keymet is contraindicated in patients with severe renal impairment (eGFR <30 mL/min/1.73 m²), acute or chronic liver disease, known hypersensitivity to metformin, or those who have experienced lactic acidosis while on metformin therapy.

Metformin Hydrochloride, the active ingredient in Keymet, is a Biguanide presented as an oral tablet for oral use. It is used to lower elevated blood glucose levels in adults with type 2 diabetes mellitus.

Indications & Clinical Uses

Keymet (Metformin Hydrochloride) belongs to the biguanide class and is employed in disorders of glucose metabolism.

Type 2 diabetes mellitus: improves glycaemic control by reducing hepatic glucose output and enhancing peripheral insulin sensitivity.
Prediabetes: helps delay progression to diabetes by lowering fasting plasma glucose.
Polycystic ovary syndrome: reduces insulin resistance, which can improve ovulatory function and hormonal balance.

How It Works

Metformin Hydrochloride acts primarily by inhibiting mitochondrial respiratory‑chain complex I, which decreases hepatic gluconeogenesis. It also increases peripheral glucose uptake and utilization by activating AMP‑activated protein kinase (AMPK), thereby improving insulin sensitivity and lowering circulating blood glucose concentrations.

Side Effects

Metformin Hydrochloride may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

Gastrointestinal upset: nausea, abdominal discomfort, or loss of appetite.
Diarrhea: loose stools occurring especially after treatment initiation.
Metallic taste: transient alteration in taste perception.

Serious or Rare Side Effects

Lactic acidosis: a rare but life‑threatening accumulation of lactate, particularly in patients with renal impairment.
Severe skin reactions: such as Stevens‑Johnson syndrome or toxic epidermal necrolysis.
Vitamin B12 deficiency: may develop with long‑term therapy, leading to neuropathy or anemia.

Precautions & Warnings

Metformin Hydrochloride requires careful monitoring and patient education to minimise risks.

Renal function assessment: avoid use in patients with severe renal impairment (eGFR <30 mL/min/1.73 m²).
Hepatic function evaluation: contraindicated in acute or chronic liver disease due to lactic acidosis risk.
Lactic acidosis risk: discontinue before any radiographic contrast studies that may affect kidney function.
Elderly dosing: consider lower starting dose and titrate slowly.
Drug‑induced vitamin B12 deficiency: monitor levels during prolonged therapy.
Store at room temperature: keep in the original container, protect from moisture and heat.

Avoid Interactions

Metformin Hydrochloride can interact with several medicines, altering its efficacy or safety profile.

Major Interactions (Avoid)

Iodinated contrast agents: may precipitate acute renal failure and increase lactic acidosis risk.
Cimetidine: can raise metformin plasma concentrations, enhancing toxicity.
Alcohol excess: potentiates lactic acidosis, especially in patients with hepatic disease.

Moderate Interactions (Monitor Closely)

Diuretics: may affect renal clearance, requiring dose adjustment.
Beta‑blockers: can mask hypoglycaemic symptoms, though metformin rarely causes hypoglycaemia.
ACE inhibitors or ARBs: combined use may impact renal function, necessitating monitoring.
NSAIDs: may reduce renal perfusion, increasing metformin accumulation.
