Actoplus Met is a prescription medication combining two distinct oral antidiabetic agents, pioglitazone and metformin hydrochloride, designed to improve glycemic control in adults with type 2 diabetes mellitus. This fixed-dose combination therapy is indicated when treatment with both pioglitazone and metformin is appropriate. It functions by targeting two primary pathophysiological defects of type 2 diabetes: insulin resistance and hepatic glucose overproduction. By addressing these mechanisms synergistically, Actoplus Met provides a comprehensive approach to managing blood glucose levels, often reducing the need for multiple separate tablets and simplifying treatment regimens for appropriate patients.

Features

• Contains two active ingredients: pioglitazone (a thiazolidinedione) and metformin hydrochloride (a biguanide)
• Available in fixed-dose combination tablets (e.g., pioglitazone/metformin HCl 15 mg/500 mg, 15 mg/850 mg)
• Oral administration, typically twice daily with meals
• Works through complementary mechanisms to reduce insulin resistance and decrease hepatic glucose production
• Not indicated for use in type 1 diabetes or diabetic ketoacidosis

Benefits

• Provides dual-mechanism action targeting both peripheral insulin resistance and excessive hepatic glucose production
• May help achieve lower HbA1c levels compared to monotherapy with either component alone
• Can reduce the number of daily pills for patients requiring both medications
• May improve lipid profiles in some patients
• Offers convenient dosing for appropriate patients already stabilized on both components
• Provides a comprehensive approach to glycemic control through complementary mechanisms

Common use

Actoplus Met is commonly prescribed for the management of type 2 diabetes mellitus in adults when treatment with both pioglitazone and metformin is appropriate. It is typically used when monotherapy with metformin, pioglitazone, or other antidiabetic agents has provided inadequate glycemic control. The medication may be used as initial combination therapy in patients with significantly elevated HbA1c levels at diagnosis or added to existing treatment regimens when additional glycemic control is needed. Healthcare providers may prescribe Actoplus Met for patients who would benefit from the complementary mechanisms of action addressing both insulin resistance and reduced insulin secretion.

Dosage and direction

The dosage of Actoplus Met should be individualized based on the patient’s current regimen, effectiveness, and tolerability. The usual starting dose is based on the patient’s current doses of pioglitazone and metformin. Typically administered twice daily with meals to reduce gastrointestinal side effects associated with metformin. Dose titration should be gradual, with increments made no more frequently than every 1-2 weeks based on fasting plasma glucose and HbA1c levels. Maximum recommended daily dose is pioglitazone 45 mg/metformin 2550 mg. Renal function should be assessed before initiation and regularly during treatment. Not recommended for patients with estimated glomerular filtration rate (eGFR) below 30 mL/min/1.73 m².

Precautions

Regular monitoring of renal function is essential before and during treatment. Assess hepatic function before initiation and periodically thereafter. Monitor for signs and symptoms of heart failure, as thiazolidinediones can cause fluid retention that may lead to or exacerbate heart failure. Regular ophthalmologic examinations are recommended due to risk of diabetic macular edema. Monitor for vitamin B12 deficiency with prolonged metformin use. Temporary discontinuation may be necessary for procedures using intravascular iodinated contrast materials. Use caution in elderly patients, those with adrenal or pituitary insufficiency, and patients consuming alcohol. Monitor for signs of hypoglycemia when used with other antidiabetic agents.

Contraindications

Actoplus Met is contraindicated in patients with severe renal impairment (eGFR below 30 mL/min/1.73 m²) or renal disease. Contraindicated in patients with metabolic acidosis, including diabetic ketoacidosis. Should not be used in patients with acute or chronic metabolic acidosis. Contraindicated in patients with history of hypersensitivity to pioglitazone, metformin, or any component of the formulation. Not recommended for patients with clinical evidence of active liver disease or elevated liver enzymes. Contraindicated in patients with severe heart failure (NYHA Class III or IV). Should not be used during radiographic studies involving intravascular iodinated contrast materials.

Possible side effects

Common side effects include gastrointestinal symptoms such as diarrhea, nausea, vomiting, abdominal discomfort, and flatulence. Hypoglycemia may occur, particularly when used with other antidiabetic agents. Weight gain and edema have been reported with thiazolidinedione components. Other potential side effects include headache, upper respiratory infection, sinusitis, myalgia, tooth disorder, and increased sweating. Rare but serious side effects include lactic acidosis (with metformin component), congestive heart failure, hepatic effects, bone fractures (particularly in female patients), bladder cancer (with prolonged pioglitazone use), and vitamin B12 deficiency with metformin component.

Drug interaction

Actoplus Met may interact with drugs that affect renal function or compete for renal tubular transport systems. Cationic drugs (amiloride, digoxin, morphine, procainamide, quinidine, quinine, ranitidine, triamterene, trimethoprim, or vancomycin) may increase metformin levels. Drugs that affect glycemic control (corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blockers, and isoniazid) may require dosage adjustment. CYP2C8 inhibitors (gemfibrozil) may increase pioglitazone concentrations. Alcohol consumption may increase risk of lactic acidosis. Certain contrast media may affect renal function and increase metformin accumulation.

Missed dose

If a dose of Actoplus Met is missed, patients should take it as soon as they remember, unless it is almost time for the next scheduled dose. In that case, the missed dose should be skipped and the regular dosing schedule resumed. Patients should not take a double dose to make up for a missed dose. Consistent timing of administration helps maintain stable blood levels of the medication. Healthcare providers should educate patients on the importance of regular dosing and what to do if doses are missed. If multiple doses are missed, patients should contact their healthcare provider for guidance on resuming therapy.

Overdose

Overdose of Actoplus Met may lead to hypoglycemia, lactic acidosis, and other metformin-associated adverse effects. Symptoms of hypoglycemia include hunger, sweating, tremor, rapid heartbeat, confusion, and in severe cases, loss of consciousness. Lactic acidosis presents with non-specific symptoms including malaise, myalgia, respiratory distress, abdominal pain, hypothermia, and bradycardia. Management of overdose should include supportive measures based on the patient’s clinical status. Hypoglycemia should be treated with oral glucose or intravenous dextrose. Hemodialysis may be effective in removing metformin and correcting acidosis. There is no specific antidote for pioglitazone overdose.

Storage

Store Actoplus Met tablets at controlled room temperature, 20°C to 25°C (68°F to 77°F), with excursions permitted between 15°C and 30°C (59°F and 86°F). Keep in the original container with the lid tightly closed to protect from moisture. Keep out of reach of children and pets. Do not use medication that has expired or shows signs of deterioration. Protect from light and excessive moisture. Do not store in bathroom cabinets where humidity levels may fluctuate. Proper storage helps maintain medication stability and effectiveness throughout the shelf life.

Reviews

Clinical studies have demonstrated that Actoplus Met provides significant improvements in glycemic control compared to monotherapy with either component. In randomized controlled trials, the combination therapy showed greater reductions in HbA1c and fasting plasma glucose than either pioglitazone or metformin alone. Many patients and healthcare providers report satisfactory glycemic control with the convenience of a combination tablet. Some patients note gastrointestinal side effects initially, which often diminish with continued use. Healthcare providers appreciate the dual-mechanism approach for addressing multiple pathophysiological aspects of type 2 diabetes. Long-term users often report stable glycemic control with appropriate monitoring and dose adjustments.
