Dayclazide Mp

Uses

Gliclazide is used for control of blood glucose in patients with non-insulin dependent diabetes mellitus (Type-II, maturity onset diabetes mellitus) whose hyperglycemia cannot be controlled by diet alone.

Metformin Hydrochloride, as monotherapy, is used for an adjunct to diet to lower blood glucose especially in overweight patients with non-insulin-dependent diabetes mellitus (NIDDM) or type 2 diabetes mellitus whose hyperglycemia cannot be satisfactorily managed on diet alone. Metformin Hydrochloride may be used concomitantly with a sulfonylurea when diet and metformin hydrochloride or sulfonylureas alone do not result in adequate glycemic control.

Pioglitazone is used for an adjunct to diet and exercise to improve glycaemic control in patients with type II diabetes (NIDDM). Pioglitazone is used for monotherapy and also used for use in combination with sulphonylurea, Metformin or Insulin when diet and exercise plus the single agent does not result in adequate glycaemic control.

Dayclazide Mp is also used to associated treatment for these conditions: Type 2 Diabetes MellitusPolycystic Ovaries Syndrome, Type 2 Diabetes Mellitus, Glycemic ControlDiabetes, Diabetic Neuropathies, Type 2 Diabetes Mellitus

How Dayclazide Mp works

Gliclazide binds to the β cell sulfonyl urea receptor (SUR1). This binding subsequently blocks the ATP sensitive potassium channels. The binding results in closure of the channels and leads to a resulting decrease in potassium efflux leads to depolarization of the β cells. This opens voltage-dependent calcium channels in the β cell resulting in calmodulin activation, which in turn leads to exocytosis of insulin containing secretorty granules.

Metformin's mechanisms of action are unique from other classes of oral antihyperglycemic drugs. Metformin decreases blood glucose levels by decreasing hepatic glucose production (gluconeogenesis), decreasing the intestinal absorption of glucose, and increasing insulin sensitivity by increasing peripheral glucose uptake and utilization . It is well established that metformin inhibits mitochondrial complex I activity, and it has since been generally postulated that its potent antidiabetic effects occur through this mechanism . The above processes lead to a decrease in blood glucose, managing type II diabetes and exerting positive effects on glycemic control.

After ingestion, the organic cation transporter-1 (OCT1) is responsible for the uptake of metformin into hepatocytes (liver cells). As this drug is positively charged, it accumulates in cells and in the mitochondria because of the membrane potentials across the plasma membrane as well as the mitochondrial inner membrane. Metformin inhibits mitochondrial complex I, preventing the production of mitochondrial ATP leading to increased cytoplasmic ADP:ATP and AMP:ATP ratios . These changes activate AMP-activated protein kinase (AMPK), an enzyme that plays an important role in the regulation of glucose metabolism . Aside from this mechanism, AMPK can be activated by a lysosomal mechanism involving other activators. Following this process, increases in AMP:ATP ratio also inhibit fructose-1,6-bisphosphatase enzyme, resulting in the inhibition of gluconeogenesis, while also inhibiting adenylate cyclase and decreasing the production of cyclic adenosine monophosphate (cAMP) , a derivative of ATP used for cell signaling . Activated AMPK phosphorylates two isoforms of acetyl-CoA carboxylase enzyme, thereby inhibiting fat synthesis and leading to fat oxidation, reducing hepatic lipid stores and increasing liver sensitivity to insulin .

In the intestines, metformin increases anaerobic glucose metabolism in enterocytes (intestinal cells), leading to reduced net glucose uptake and increased delivery of lactate to the liver. Recent studies have also implicated the gut as a primary site of action of metformin and suggest that the liver may not be as important for metformin action in patients with type 2 diabetes. Some of the ways metformin may play a role on the intestines is by promoting the metabolism of glucose by increasing glucagon-like peptide I (GLP-1) as well as increasing gut utilization of glucose .

In addition to the above pathway, the mechanism of action of metformin may be explained by other ways, and its exact mechanism of action has been under extensive study in recent years .

Pioglitazone is a selective agonist at peroxisome proliferator-activated receptor-gamma (PPARγ) in target tissues for insulin action such as adipose tissue, skeletal muscle, and liver. Activation of PPARγ increases the transcription of insulin-responsive genes involved in the control of glucose and lipid production, transport, and utilization. Through this mechanism, pioglitazone both enhances tissue sensitivity to insulin and reduces the hepatic production of glucose (i.e. gluconeogenesis) - insulin resistance associated with type 2 diabetes mellitus is therefore improved without an increase in insulin secretion by pancreatic beta cells.

Dosage

Dayclazide Mp dosage

Adult: The usual initial dose of Gliclazideis 40 to 80 mg daily, gradually increased, if necessary up to 320 mg daily until adequate control is achieved. A single dose should not exceed 160 mg. When higher doses are required it should be taken twice daily, according to the main meals of the day. For extended release tablet the initial recommended dose is 30 mg daily, even in elderly patients (>65 years); the daily dose may vary from 30 to 120 mg taken orally, once daily.

Gliclazide extend release tablet should be taken with food because there is increased risk of hypoglycemia if a meal is taken late. It is recommended that the medication be taken at breakfast time. If a dose is forgotten, the dose taken on the next day should not be increased. Dose titration should be carried out in steps of 30 mg, according to the fasting blood glucose response. Each step should last for at least two weeks. Gliclazide extend release tabletshould be neither broken nor chewed. Gliclazide extend release tablet30 mg, can replace Gliclazide 80 mg tabletsfor doses of 1 to 4 tablets per day.

Elderly: Plasma clearance of Gliclazide is not altered in the elderly and steady state plasma levels are similar to those in adults under 65 years. Clinical experience in the elderly shows that it is effective and well tolerated.

Children: Gliclazide as with other sulfonylureas is not indicated for the treatment of juvenile onset diabetes mellitus.

Adult-

Metformin 500 mg tablet: Initial dosage is 500 mg tablet 2-3 times daily with or after meals, gradually increased if necessary to 2 to 3 gm daily.

Metformin 850 mg tablet: Initial dosage is 850 mg tablet once or twice daily with or after meals, gradually increased if necessary to 2 to 3 gm daily.

Metformin extended release orlong acting tablet: The usual starting dose of Metformin extended release tabletis 500 mg once daily with the evening meal. Dosage increases should be made in increments of 500 mg weekly, up to a maximum of 2000 mg once daily with the evening meal. If glycemic control is not achieved on Metformin extended release tablet 2000 mg once daily, a trial of Metformin extended release tablet 1000 mg twice daily should be considered. The maximum recommended dose of metformin is 3 gm daily.

Transfer from other antidiabetic therapy: When transferring patients from standard oral hypoglycemic agents other than Chlorpropamide to Metformin HCl, no transition period generally is necessary. When transferring patients fromChlorpropamide, care should be exercised during the first two weeks because of the prolonged retention of Chlorpropamide in the body, leading to overlapping drug effects and possible hypoglycemia.

Children and adolescents-

Monotherapy and combination with insulin

• Metformin tablets can be used in children from 10 years of age and adolescents.
• The usual starting dose is one tablet of 500 mg or 850 mg once daily, given during meals or after meals.

After 10 to 15 days the should be adjusted on the basis of blood glucose measurements. A slow increase of dose may improve gastrointestinal tolerability. The maximum recommended dose of metformin is 2 g daily, taken as 2 or 3 divided doses.

Elderly-

Due to the potential for decreased renal function in elderly subjects, the metformin dosage should be adjusted based on renal function. Regular assessment of renal function is necessary.

Pioglitazone can be taken once daily without regard to meals. The management of antidiabetic therapy should be individualized. Pioglitazone monotherapy may be initiated at 15 mg or 30 mg once daily dosages in patients not adequately controlled with diet and exercise alone. For patients who respond inadequately to the initial dose of Pioglitazone, the dose can be increased up to 45 mg once daily. For patients not responding adequately to monotherapy, combination therapy should be considered.

Maximum recommended daily dose of Pioglitazone should not exceed 45 mg since doses higher than 45 mg have not been studied in placebo controlled clinical studies. Besides, no placebo controlled clinical studies of more than 30 mg once daily have been conducted in combination therapy.

Side Effects

Hypoglycemia may occur in concurrent conditions such as hepatic & renal diseases, alcohol intoxication and adrenal and pituitary insufficiency. Mild gastro-intestinal disturbances including nausea, dyspepsia, diarrhea, and constipation have been reported but these types of adverse reactions can be avoided if Gliclazide is taken during a meal. Allergic dermatological reactions including rash, prurits, erythema, bullous eruption have been reported during treatment with the drug but are not known to be directly attributable to it. More serious reactions like leucopenia, thrombocytopenia, agranulocytosis, pancytopenia, hemolytic anemia, cholestatic jaundice, GI hemorrhage have not been reported with Gliclazide.

Metformin may cause gastro-intestinal adverse effects like diarrhoea, anorexia, nausea & vomiting. Lactic acidosis and malabsorption of vitamin B12 may be occurred. Patients may experience a metallic taste and there may be weight loss, which in some diabetics could be an advantage.

The overall incidence and types of adverse events reported in placebo controlled clinical trials of Pioglitazone monotherapy at doses of 7.5 mg, 15 mg, 30 mg or 45 mg once daily are upper respiratory tract infection (13.2%), headache (9.1%), sinusitis (6.3%), myalgia (5.4%), tooth disorder (5.3%), and pharyngitis (5.1%).

Toxicity

LD₅₀=3000 mg/kg (orally in mice). Gliclazide and its metabolites may accumulate in those with severe hepatic and/or renal dysfunction. Symptoms of hypoglycemia include: dizziness, lack of energy, drowsiness, headache and sweating.

Metformin (hydrochloride) toxicity data:

Oral LD50 (rat): 1 g/kg; Intraperitoneal LD50 (rat): 500 mg/kg; Subcutaneous LD50 (rat): 300 mg/kg; Oral LD50 (mouse): 1450 mg/kg; Intraperitoneal LD50 (mouse): 420 mg/kg; Subcutaneous LD50 (mouse): 225 mg/kg .

A note on lactic acidosis

Metformin decreases liver uptake of lactate, thereby increasing lactate blood levels which may increase the risk of lactic acidosis . There have been reported postmarketing cases of metformin-associated lactic acidosis, including some fatal cases. Such cases had a subtle onset and were accompanied by nonspecific symptoms including malaise, myalgias, abdominal pain, respiratory distress, or increased somnolence. In certain cases, hypotension and resistant bradyarrhythmias have occurred with severe lactic acidosis . Metformin-associated lactic acidosis was characterized by elevated blood lactate concentrations (>5 mmol/L), anion gap acidosis (without evidence of ketonuria or ketonemia), as well as an increased lactate:pyruvate ratio; metformin plasma levels were generally >5 mcg/mL.

Risk factors for metformin-associated lactic acidosis include renal impairment, concomitant use of certain drugs (e.g. carbonic anhydrase inhibitors such as topiramate), age 65 years old or greater, having a radiological study with contrast, surgery and other procedures, hypoxic states (e.g., acute congestive heart failure), excessive alcohol intake, and hepatic impairment .

A note on renal function

In patients with decreased renal function, the plasma and blood half-life of metformin is prolonged and the renal clearance is decreased .

Metformin should be avoided in those with severely compromised renal function (creatinine clearance < 30 ml/min), acute/decompensated heart failure, severe liver disease and for 48 hours after the use of iodinated contrast dyes due to the risk of lactic acidosis . Lower doses should be used in the elderly and those with decreased renal function. Metformin decreases fasting plasma glucose, postprandial blood glucose and glycosolated hemoglobin (HbA1c) levels, which are reflective of the last 8-10 weeks of glucose control. Metformin may also have a positive effect on lipid levels.

A note on hypoglycemia

When used alone, metformin does not cause hypoglycemia, however, it may potentiate the hypoglycemic effects of sulfonylureas and insulin when they are used together .

Use in pregnancy

Available data from post-marketing studies have not indicated a clear association of metformin with major birth defects, miscarriage, or adverse maternal or fetal outcomes when metformin was ingested during pregnancy. Despite this, the abovementioned studies cannot definitively establish the absence of any metformin-associated risk due to methodological limitations, including small sample size and inconsistent study groups .

Use in nursing

A limited number of published studies indicate that metformin is present in human milk. There is insufficient information to confirm the effects of metformin on the nursing infant and no available data on the effects of metformin on the production of milk. The developmental and health benefits of breastfeeding should be considered as well as the mother’s clinical need for metformin and any possible adverse effects on the nursing child .

The oral TDLo observed in mice is 24 mg/kg for 4 days and for rats is 3 mg/kg for 6 days.

One instance of overdose was reported during clinical trials with pioglitazone in which a patient took an oral dose of 120mg daily for four days, followed by 180mg daily for seven days - this patient did not report any adverse clinical symptoms during this time. In the event of overdosage, employ symptomatic and supportive measures according to the patient's clinical status.

Precaution

Gliclazide should be used carefully in patients with hepatic impairment. If there is definite hepatic disease then gliclazide should not be used. Consucon (Gliclazide) can be used safely in patients with renal insufficiency as it is extensively metabolized. Consucon has less sudden hypoglycaemic episode than other sulfonylurea group of drugs.

Lactic acidosis is a rare, but serious (high mortality in the absence of prompt treatment), metabolic complication that can occur due to metformin accumulation. Reported cases of lactic acidosis in patients on metformin have occurred primarily in diabetic patients with significant renal failure. The incidence of lactic acidosis can and should be reduced by assessing also other associated risk factors such as poorly controlled diabetes, ketosis, prolonged fasting, excessive alcohol intake, hepatic insufficiency and any condition associated with hypoxia. Lactic acidosis is characterized by acidotic dyspnea, abdominal pain and hypothermia followed by coma. Diagnostic laboratory findings are decreased blood pH, plasma lactate levels above 5 mmol/L, and an increased anion gap and lactate/pyruvate ratio. If metabolic acidosis is suspected, metformin should be discontinued and the patient should be hospitalized immediately.

Renal function: As metformin is excreted by the kidney, serum creatinine levels should be determined before initiating treatment and regularly thereafter: at least annually in patients with normal renal function, at least two to four times a year in patients with serum creatinine levels at the upper limit of normal and in elderly subjects. Decreased renal function in elderly subjects is frequent and asymptomatic. Special caution should be exercised in situations where renal function may become impaired, for example when initiating antihypertensive therapy or diuretic therapy and when starting therapy with an NSAID.

Administration of iodinated contrast agent: As the intravascular administration of iodinated contrast materials in radiologic studies can lead to renal failure, metformin should be discontinued prior to, or at the time of the test and not reinstituted until 48 hours afterwards, and only after renal function has been re-evaluated and found to be normal.

Surgery: Metformin hydrochloride should be discontinued 48 hours before elective surgery with general anesthesia and should not be usually resumed earlier than 48 hours afterwards.

Children and adolescents: The diagnosis of type 2 diabetes mellitus should be confirmed before treatment with metformin is initiated. No effect of metformin on growth and puberty has been detected during controlled clinical studies of one-year duration but no long-term data on these specific points are available. Therefore, a careful follow-up of the effect of metformin on these parameters in metformin-treated children, especially pre-pubescent children, is recommended.

Children aged between 10 and 12 years: Only 15 subjects aged between 10 and 12 years were included in the controlled clinical studies conducted in children and adolescents. Although metformin efficacy and safety in children below 12 did not differ from efficacy and safety in older children, particular caution is recommended when prescribing to children aged between 10 and 12 years.

Other precautions: All patients should continue their diet with a regular distribution of carbohydrate intake during the day. Overweight patients should continue their energy-restricted diet. The usual laboratory tests for diabetes monitoring should be performed regularly. Metformin alone never causes hypoglycemia, although caution is advised when it is used in combination with insulin or sulphonylureas.

Pioglitazone exerts its antihyperglycaemic effect only in the presence of Insulin. Therefore, it should not be used in Type 1 diabetes or for the treatment of diabetic ketoacidosis. Pioglitazone should be used with caution in case of combination antidiabetic therapy and hepatic insufficiency. Liver enzyme should be monitored regularly.

Interaction

The hypoglycemic effect of Gliclazide may be potentiated by NSAID (in particular aspirin), phenylbutazone, sulfonamides, coumarin derivatives, MAOIs, beta-adrenergic blockers, tetracyclines, chloramphenicol, clofibrate, cimetidine and miconazole tablets. Ingestion of alcohol may also increase the hypoglycemic effect of Gliclazide. Some drugs may on the contrary, reduce its activity e.g. barbiturates, corticosteroides, thiazide diuretics, thyroid hormones, laxatives and oral contraceptives.

Concomitant use not recommended-

Alcohol: Increased risk of lactic acidosis in acute alcohol intoxication, particularly in case of: fasting or malnutrition, hepatic insufficiency. Avoid consumption of alcohol and alcohol-containing medications.

Iodinated contrast agents: Intravascular administration of iodinated contrast agents may lead to renal failure, resulting in metformin accumulation and a risk of lactic acidosis. Metformin should be discontinued prior to, or at the time of the test and not reinstituted until 48 hours afterwards, and only after renal function has been re-evaluated and found to be normal.

Combinations requiring precautions for use-

Certain drugs tend to produce hyperglycemia and may lead to loss of glycemic control. These drugs include thiazide and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blocking drugs, and isoniazid. When such drugs are administered to a patient receiving Metformin HCl, the patient should be closely observed to maintain adequate glycemic control. Inform the patient and perform more frequent blood glucose monitoring, especially at the beginning of treatment. If necessary, adjust the dosage of the antidiabetic drug during therapy with the other drug and upon its discontinuation.

Nifedipine appears to enhance the absorption of Metformin. Metformin has minimal effects on nifedipine. ACE-inhibitors may decrease the blood glucose levels. If necessary, adjust the dosage of the antidiabetic drug during therapy with the other drug and upon its discontinuation.

Administration of thiazolidinediones with an oral contraceptive containing ethinyl oestradiol and norethindrone reduces the plasma concentration of both hormones by approximately 30% which could result in loss of contraception.

Volume of Distribution

The apparent volume of distribution (V/F) of metformin after one oral dose of metformin 850 mg averaged at 654 ± 358 L .

The average apparent volume of distribution of pioglitazone is 0.63 ± 0.41 L/kg.

Elimination Route

Rapidly and well absorbed but may have wide inter- and intra-individual variability. Peak plasma concentrations occur within 4-6 hours of oral administration.

Regular tablet absorption

The absolute bioavailability of a metformin 500 mg tablet administered in the fasting state is about 50%-60%. Single-dose clinical studies using oral doses of metformin 500 to 1500 mg and 850 to 2550 mg show that there is a lack of dose proportionality with an increase in metformin dose, attributed to decreased absorption rather than changes in elimination .

At usual clinical doses and dosing schedules of metformin, steady-state plasma concentrations of metformin are achieved within 24-48 hours and are normally measured at Label.

Extended-release tablet absorption

After a single oral dose of metformin extended-release, Cmax is reached with a median value of 7 hours and a range of between 4 and 8 hours. Peak plasma levels are measured to be about 20% lower compared to the same dose of regular metformin, however, the extent of absorption of both forms (as measured by area under the curve - AUC), are similar .

Effect of food

Food reduces the absorption of metformin, as demonstrated by about a 40% lower mean peak plasma concentration (Cmax), a 25% lower area under the plasma concentration versus time curve (AUC), and a 35-minute increase in time to peak plasma concentration (Tmax) after ingestion of an 850 mg tablet of metformin taken with food, compared to the same dose administered during fasting .

Though the extent of metformin absorption (measured by the area under the curve - AUC) from the metformin extended-release tablet is increased by about 50% when given with food, no effect of food on Cmax and Tmax of metformin is observed. High and low-fat meals exert similar effects on the pharmacokinetics of extended-release metformin .

Following oral administration of pioglitazone, peak serum concentrations are observed within 2 hours (T_max) - food slightly delays the time to peak serum concentration, increasing T_max to approximately 3-4 hours, but does not alter the extent of absorption. Steady-state concentrations of both parent drug and its primary active metabolites are achieved after 7 days of once-daily administration of pioglitazone. C_max and AUC increase proportionately to administered doses.

Half Life

10.4 hours. Duration of action is 10-24 hours.

Approximately 6.2 hours in the plasma and in the blood, the elimination half-life is approximately 17.6 hours, suggesting that the erythrocyte mass may be a compartment of distribution .

The mean serum half-life of pioglitazone and its metabolites (M-III and M-IV) range from 3-7 hours and 16-24 hours, respectively.

Clearance

Renal clearance is about 3.5 times greater than creatinine clearance, which indicates that tubular secretion is the major route of metformin elimination. Following oral administration, approximately 90% of the absorbed drug is eliminated via the renal route within the first 24 hours .

The apparent clearance of orally administered pioglitazone is 5-7 L/h.

Elimination Route

Metabolites and conjugates are eliminated primarily by the kidneys (60-70%) and also in the feces (10-20%).

This drug is substantially excreted by the kidney .

Renal clearance of metformin is about 3.5 times higher than creatinine clearance, which shows that renal tubular secretion is the major route of metformin elimination. After oral administration, about 90% of absorbed metformin is eliminated by the kidneys within the first 24 hours post-ingestion .

Approximately 15-30% of orally administered pioglitazone is recovered in the urine. The bulk of its elimination, then, is presumed to be through the excretion of unchanged drug in the bile or as metabolites in the feces.

Pregnancy & Breastfeeding use

Pregnant Women: Gliclazide should not be used in pregnant women although animal studies of Gliclazide have not shown any teratogenic effect.

Nursing Mothers: This drug is contraindicated when breast feeding.

Pregnancy Category B. Animal studies do not indicate harmful effects with respect to pregnancy, embryonic or fetal development, parturition or postnatal development. There are no adequate and well-controlled studies in pregnant women. Can be used in pregnancy for both preexisting and gestational diabetes. Women with gestational diabetes should discontinue treatment after giving birth.

Lactation: Metformin is excreted into milk in lactating rats. Similar data is not available in humans and a decision should be made whether to discontinue nursing or to discontinue metformin, taking into account the importance of the drug to the mother. May be used during breast-feeding in women with pre existing diabetes.

Pregnancy: There are no adequate and well controlled studies in pregnant women. Pioglitazone should be used during pregnancy only if the potential benefit justifies the potential risk to the foetus.

Lactation: It is not known whether Pioglitazone is secreted in human milk. As many drugs are excreted in human milk, it should not be administered to a lactating women.

Contraindication

Hypersensitivity to sulfonylurea, diabetes complicated by ketoacidosis with coma, as a sole therapy of insulin-dependent (Type-1) diabetes mellitus, diabetes when complicated by pregnancy & breast-feeding.

• Hypersensitivity to metformin hydrochloride or to any of the excipients of the medication.
• Diabetic ketoacidosis, diabetic pre-coma
• Renal failure or renal dysfunction (creatinine clearance < 60 mL/min)
• Acute conditions with the potential to alter renal function such as: dehydration, severe infection, shock, intravascular
• administration of iodinated contrast agents.
• Acute or chronic disease which may cause tissue hypoxia such as: cardiac or respiratory failure, recent myocardial
• infarction, shock
• Hepatic insufficiency, acute alcohol intoxication, alcoholism
• Lactation

Pioglitazone is contraindicated in patients with known hypersensitivity to any of its components.

Special Warning

Elderly: Plasma clearance of Gliclazide is not altered in the elderly and steady state plasma levels are similar to those in adults under 65 years. Clinical experience in the elderly shows that it is effective and well tolerated.

Children: Gliclazide as with other sulfonylureas is not indicated for the treatment of juvenile onset diabetes mellitus.

Renal Impairment: Metformin is contraindicated in patients with an eGFR < 30 mL/minute/1.73 m2 . Starting metformin in patients with an eGFR between 30-45 mL/minute/1.73 m2 is not recommended. In patients taking metformin whose eGFR later falls below 45 mL/minute/1.73 m2 , assess the benefits and risks of continuing treatment. Discontinue metformin if the patient’s eGFR later falls below 30 mL/minute/1.73 m2 .

Acute Overdose

Symptoms: Hypoglycaemia with or without coma, convulsions or other neurological disorders.

Management: Carbohydrate intake, dosage adjustment and/or change of diet may be helpful. Admin rapid IV inj of concentrated glucose soln for hypoglycaemic coma.

Hypoglycemia has not been seen with metformin doses up to 85g, although lactic acidosis has occurred in such circumstances. High overdose or concomitant risks of metformin may lead to lactic acidosis. Lactic acidosis is a medical emergency and must be treated in hospital. The most effective method to remove lactate and metformin is hemodialysis.
