Lozol®
(indapamide) 1.25 mg Tablets
Lozol® (indapamide) is an oral antihypertensive/diuretic. Its molecule contains both a polar sulfamoyl chlorobenzamide moiety and a lipid-soluble methylindoline moiety. It differs chemically from the thiazides in that it does not possess the thiazide ring system and contains only one sulfonamide group. The chemical name of Lozol is 1-(4-chloro-3sulfamoylbenzamido)-2-methylindoline, and its molecular weight is 365.84. The compound is a weak acid, pKa=8.8, and is soluble in aqueous solutions of strong bases. It is a white to yellow-white crystalline (tetragonal) powder.

Lozol is indicated for the treatment of hypertension, alone or in combination with other antihypertensive drugs.
Lozol is also indicated for the treatment of salt and fluid retention associated with congestive heart failure.
The routine use of diuretics in an otherwise healthy woman is inappropriate and exposes mother and fetus to unnecessary hazard (see PRECAUTIONS below).
Diuretics do not prevent development of toxemia of pregnancy, and there is no satisfactory evidence that they are useful in the treatment of developed toxemia.
Edema during pregnancy may arise from pathological causes or from the physiologic and mechanical consequences of pregnancy. Indapamide is indicated in pregnancy when edema is due to pathologic causes, just as it is in the absence of pregnancy (however, see PRECAUTIONS below). Dependent edema in pregnancy, resulting from restriction of venous return by the expanded uterus, is properly treated through elevation of the lower extremities and use of support hose; use of diuretics to lower intravascular volume in this case is illogical and unnecessary. There is hypervolemia during normal pregnancy which is not harmful to either the fetus or the mother (in the absence of cardiovascular disease), but which is associated with edema, including generalized edema in the majority of pregnant women. If this edema produces discomfort, increased recumbency will often provide relief. In rare instances, this edema may cause extreme discomfort which is not relieved by rest. In these cases, a short course of diuretics may provide relief and may be appropriate.
The adult starting indapamide dose for hypertension is 1.25 mg as a single daily dose taken in the morning. If the response to 1.25 mg is not satisfactory after four weeks, the daily dose may be increased to 2.5 mg taken once daily. If the response to 2.5 mg is not satisfactory after four weeks, the daily dose may be increased to 5.0 mg taken once daily, but adding another antihypertensive should be considered.
The adult starting indapamide dose for edema of congestive heart failure is 2.5 mg as a single daily dose taken in the morning. If the response to 2.5 mg is not satisfactory after one week, the daily dose may be increased to 5.0 mg taken once daily.
If the antihypertensive response to indapamide is insufficient, Lozol may be combined with other antihypertensive drugs, with careful monitoring of blood pressure. It is recommended that the usual dose of other agents be reduced by 50% during initial combination therapy. As the blood pressure response becomes evident, further dosage adjustments may be necessary.
In general, doses of 5.0 mg and larger have not appeared to provide additional effects on blood pressure or heart failure, but are associated with a greater degree of hypokalemia. There is minimal clinical trial experience in patients with doses greater than 5.0 mg once a day.

Most adverse effects have been mild and transient.
The Clinical Adverse Reactions listed in Table 1 represent data from Phase II/III placebo-controlled studies (306 patients given indapamide 1.25 mg). The Clinical Adverse Reactions listed in Table 2 represent data from Phase II placebo-controlled studies and long-term controlled clinical trials (426 patients given Lozol 2.5 mg or 5.0 mg). The reactions are arranged into two groups: 1) a cumulative incidence equal to or greater than 5%; 2) a cumulative incidence less than 5%. Reactions are counted regardless of relation to drug.

All other clinical adverse reactions occurred at an incidence of < 1%.
Approximately 4% of patients given indapamide 1.25 mg compared to 5% of the patients given placebo discontinued treatment in the trials of up to eight weeks because of adverse reactions. In controlled clinical trials of six to eight weeks in duration, 20% of patients receiving indapamide 1.25 mg, 61% of patients receiving indapamide 5.0 mg, and 80% of patients receiving indapamide 10.0 mg had at least one potassium value below 3.4 mEq/L. In the indapamide 1.25 mg group, about 40% of those patients who reported hypokalemia as a laboratory adverse event returned to normal serum potassium values without intervention. Hypokalemia with concomitant clinical signs or symptoms occurred in 2% of patients receiving indapamide 1.25 mg.

Because most of these data are from long-term studies (up to 40 weeks of treatment), it is probable that many of the adverse experiences reported are due to causes other than the drug. Approximately 10% of patients given indapamide discontinued treatment in long-term trials because of reactions either related or unrelated to the drug.
Hypokalemia with concomitant clinical signs or symptoms occurred in 3% of patients receiving indapamide 2.5 mg q.d. and 7% of patients receiving indapamide 5 mg q.d. In long-term controlled clinical trials comparing the hypokalemic effects of daily doses of indapamide and hydrochlorothiazide, however, 47% of patients receiving indapamide 2.5 mg, 72% of patients receiving indapamide 5 mg, and 44% of patients receiving hydrochlorothiazide 50 mg had at least one potassium value (out of a total of 11 taken during the study) below 3.5 mEq/L. In the indapamide 2.5 mg group, over 50% of those patients returned to normal serum potassium values without intervention.
In clinical trials of six to eight weeks, the mean changes in selected values were as shown in the tables below.
| Mean Changes from Baseline after 8 Weeks of Treatment – 1.25 mg | |||||
| Serum Electrolytes (mEq/L) Potassium Sodium Chloride | Serum Uric Acid (mg/dL) | BUN (mg/dL) | |||

| (n=263-266) | 0.00 | – 0.11 | – 0.21 | 0.06 | 0.06 |
No patients receiving indapamide 1.25 mg experienced hyponatremia considered possibly clinically significant ( < 125 mEq/L). Indapamide had no adverse effects on lipids.
| Mean Changes from Baseline after 40 Weeks of Treatment – 2.5 mg and 5.0 mg | |||||

The following reactions have been reported with clinical usage of Lozol: jaundice (intrahepatic cholestatic jaundice), hepatitis, pancreatitis and abnormal liver function tests. These reactions were reversible with discontinuance of the drug.
Also reported are erythema multiforme, Stevens-Johnson Syndrome, bullous eruptions, purpura, photosensitivity, fever, pneumonitis, anaphylactic reactions, agranulocytosis, leukopenia, thrombocytopenia and aplastic anemia. Other adverse reactions reported with antihypertensive/diuretics are necrotizing angiitis, respiratory distress, sialadenitis, xanthopsia.
Lozol may add to or potentiate the action of other antihypertensive drugs. In limited controlled trials that compared the effect of indapamide combined with other antihypertensive drugs with the effect of the other drugs administered alone, there was no notable change in the nature or frequency of adverse reactions associated with the combined therapy.
See WARNINGS.
The antihypertensive effect of the drug may be enhanced in the post-sympathectomized patient.
Indapamide, like the thiazides, may decrease arterial responsiveness to norepinephrine, but this diminution is not sufficient to preclude effectiveness of the pressor agent for therapeutic use.

Severe cases of hyponatremia, accompanied by hypokalemia have been reported with recommended doses of indapamide. This occurred primarily in elderly females. (See PRECAUTIONS, Geriatric Use.) This appears to be dose related. Also, a large case-controlled pharmacoepidemiology study indicates that there is an increased risk of hyponatremia with indapamide 2.5 mg and 5 mg doses. Hyponatremia considered possibly clinically significant ( < 125 mEq/L) has not been observed in clinical trials with the 1.25 mg dosage (see PRECAUTIONS). Thus, patients should be started at the 1.25 mg dose and maintained at the lowest possible dose. (See DOSAGE AND ADMINISTRATION.)
Hypokalemia occurs commonly with diuretics (see ADVERSE REACTIONS, hypokalemia), and electrolyte monitoring is essential, particularly in patients who would be at increased risk from hypokalemia, such as those with cardiac arrhythmias or who are receiving concomitant cardiac glycosides.
In general, diuretics should not be given concomitantly with lithium because they reduce its renal clearance and add a high risk of lithium toxicity. Read prescribing information for lithium preparations before use of such concomitant therapy.
Periodic determinations of serum electrolytes should be performed at appropriate intervals. In addition, patients should be observed for clinical signs of fluid or electrolyte imbalance, such as hyponatremia, hypochloremic alkalosis, or hypokalemia. Warning signs include dry mouth, thirst, weakness, fatigue, lethargy, drowsiness, restlessness, muscle pains or cramps, hypotension, oliguria, tachycardia, and gastrointestinal disturbance. Electrolyte determinations are particularly important in patients who are vomiting excessively or receiving parenteral fluids, in patients subject to electrolyte imbalance (including those with heart failure, kidney disease, and cirrhosis), and in patients on a salt-restricted diet.
The risk of hypokalemia secondary to diuresis and natriuresis is increased when larger doses are used, when the diuresis is brisk, when severe cirrhosis is present and during concomitant use of corticosteroids or ACTH. Interference with adequate oral intake of electrolytes will also contribute to hypokalemia. Hypokalemia can sensitize or exaggerate the response of the heart to the toxic effects of digitalis, such as increased ventricular irritability.
Dilutional hyponatremia may occur in edematous patients; the appropriate treatment is restriction of water rather than administration of salt, except in rare instances when the hyponatremia is life threatening. However, in actual salt depletion, appropriate replacement is the treatment of choice. Any chloride deficit that may occur during treatment is generally mild and usually does not require specific treatment except in extraordinary circumstances as in liver or renal disease. Thiazide-like diuretics have been shown to increase the urinary excretion of magnesium; this may result in hypomagnesemia.
Serum concentrations of uric acid increased by an average of 0.69 mg/100 mL in patients treated with indapamide 1.25 mg, and by an average of 1.0 mg/100 mL in patients treated with indapamide 2.5 mg and 5.0 mg, and frank gout may be precipitated in certain patients receiving indapamide (see ADVERSE REACTIONS below). Serum concentrations of uric acid should, therefore, be monitored periodically during treatment.
Indapamide, like the thiazides, should be used with caution in patients with severe renal disease, as reduced plasma volume may exacerbate or precipitate azotemia. If progressive renal impairment is observed in a patient receiving indapamide, withholding or discontinuing diuretic therapy should be considered. Renal function tests should be performed periodically during treatment with indapamide.
Indapamide, like the thiazides, should be used with caution in patients with impaired hepatic function or progressive liver disease, since minor alterations of fluid and electrolyte balance may precipitate hepatic coma.
Latent diabetes may become manifest and insulin requirements in diabetic patients may be altered during thiazide administration. A mean increase in glucose of 6.47 mg/dL was observed in patients treated with indapamide 1.25 mg, which was not considered clinically significant in these trials. Serum concentrations of glucose should be monitored routinely during treatment with Lozol.
Calcium excretion is decreased by diuretics pharmacologically related to indapamide. After six to eight weeks of indapamide 1.25 mg treatment and in long-term studies of hypertensive patients with higher doses of indapamide, however, serum concentrations of calcium increased only slightly with indapamide. Prolonged treatment with drugs pharmacologically related to indapamide may in rare instances be associated with hypercalcemia and hypophosphatemia secondary to physiologic changes in the parathyroid gland; however, the common complications of hyperparathyroidism, such as renal lithiasis, bone resorption, and peptic ulcer, have not been seen. Treatment should be discontinued before tests for parathyroid function are performed. Like the thiazides, indapamide may decrease serum PBI levels without signs of thyroid disturbance.
Thiazides have exacerbated or activated systemic lupus erythematosus and this possibility should be considered with indapamide as well.
Both mouse and rat lifetime carcinogenicity studies were conducted. There was no significant difference in the incidence of tumors between the indapamide-treated animals and the control groups.
Pregnancy Category B. Reproduction studies have been performed in rats, mice and rabbits at doses up to 6,250 times the therapeutic human dose and have revealed no evidence of impaired fertility or harm to the fetus due to Lozol® (indapamide). Postnatal development in rats and mice was unaffected by pretreatment of parent animals during gestation. There are, however, no adequate and well-controlled studies in pregnant women. Moreover, diuretics are known to cross the placental barrier and appear in cord blood. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. There may be hazards associated with this use such as fetal or neonatal jaundice, thrombocytopenia, and possibly other adverse reactions that have occurred in the adult.
It is not known whether this drug is excreted in human milk. Because most drugs are excreted in human milk, if use of this drug is deemed essential, the patient should stop nursing.
Safety and effectiveness of indapamide in pediatric patients have not been established.
Clinical studies of indapamide did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Severe cases of hyponatremia, accompanied by hypokalemia have been reported with recommended doses of indapamide in elderly females (see WARNINGS).

Symptoms of overdosage include nausea, vomiting, weakness, gastrointestinal disorders and disturbances of electrolyte balance. In severe instances, hypotension and depressed respiration may be observed. If this occurs, support of respiration and cardiac circulation should be instituted. There is no specific antidote. An evacuation of the stomach is recommended by emesis and gastric lavage after which the electrolyte and fluid balance should be evaluated carefully.
Anuria.
Known hypersensitivity to indapamide or to other sulfonamide-derived drugs.

Indapamide is the first of a new class of antihypertensive/diuretics, the indolines. The oral administration of 2.5 mg (two 1.25 mg tablets) of indapamide to male subjects produced peak concentrations of approximately 115 ng/mL of the drug in blood within two hours. The oral administration of 5 mg (two 2.5 mg tablets) of indapamide to healthy male subjects produced peak concentrations of approximately 260 ng/mL of the drug in the blood within two hours. A minimum of 70% of a single oral dose is eliminated by the kidneys and an additional 23% by the gastrointestinal tract, probably including the biliary route. The half-life of Lozol in whole blood is approximately 14 hours.
Lozol is preferentially and reversibly taken up by the erythrocytes in the peripheral blood. The whole blood/plasma ratio is approximately 6:1 at the time of peak concentration and decreases to 3.5:1 at eight hours. From 71 to 79% of the Lozol in plasma is reversibly bound to plasma proteins.
Lozol is an extensively metabolized drug, with only about 7% of the total dose administered, recovered in the urine as unchanged drug during the first 48 hours after administration. The urinary elimination of 14C-labeled indapamide and metabolites is biphasic with a terminal half-life of excretion of total radioactivity of 26 hours.
In a parallel design double-blind, placebo controlled trial in hypertension, daily doses of indapamide between 1.25 mg and 10.0 mg produced dose-related antihypertensive effects. Doses of 5.0 and 10.0 mg were not distinguishable from each other although each was differentiated from placebo and 1.25 mg indapamide. At daily doses of 1.25 mg, 5.0 mg and 10.0 mg, a mean decrease of serum potassium of 0.28, 0.61 and 0.76 mEq/L, respectively, was observed and uric acid increased by about 0.69 mg/100 mL.
In other parallel design, dose-ranging clinical trials in hypertension and edema, daily doses of indapamide between 0.5 and 5.0 mg produced dose-related effects. Generally, doses of 2.5 and 5.0 mg were not distinguishable from each other although each was differentiated from placebo and from 0.5 or 1.0 mg indapamide. At daily doses of 2.5 and 5.0 mg a mean decrease of serum potassium of 0.5 and 0.6 mEq/Liter, respectively, was observed and uric acid increased by about 1.0 mg/100 mL.
At these doses, the effects of indapamide on blood pressure and edema are approximately equal to those obtained with conventional doses of other antihypertensive/diuretics.
In hypertensive patients, daily doses of 1.25, 2.5 and 5.0 mg of indapamide have no appreciable cardiac inotropic or chronotropic effect. The drug decreases peripheral resistance, with little or no effect on cardiac output, rate or rhythm. Chronic administration of indapamide to hypertensive patients has little or no effect on glomerular filtration rate or renal plasma flow.
Lozol had an antihypertensive effect in patients with varying degrees of renal impairment, although in general, diuretic effects declined as renal function decreased. In a small number of controlled studies, Indapamide taken with other antihypertensive drugs such as hydralazine, propranolol, guanethidine and methyldopa, appeared to have the additive effect typical of thiazide-type diuretics.

INDAPAMIDE - ORAL
(in-DAP-uh-mide)
COMMON BRAND NAME(S): Lozol
USES: This medication is used alone or in combination with other medications to treat high blood pressure (hypertension). Indapamide is also used to help the body get rid of extra salt and water that builds up with chronic heart failure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Decreasing salt and water helps to decrease the swelling and breathing problems from chronic heart failure and increases your ability to exercise.
Indapamide is a water pill (diuretic) that increases the amount of urine you make. Getting rid of extra water and salt probably helps to relax the blood vessels so that blood can flow more easily. These effects help to lower blood pressure and decrease the amount of work the heart must do to pump blood.
HOW TO USE: Take this medication by mouth with or without food, usually once daily in the morning or as directed by your doctor. It is best to take this medication early in the day (before 10 AM) to avoid having to get up during the night to urinate. Consult your doctor or pharmacist if you have questions about your dosing schedule.
The dosage is based on medical condition and response to therapy. If you have severe liver or kidney problems, your dosage may need to be adjusted.
Take indapamide at least 4 hours before or after certain cholesterol-lowering medications (bile acid-binding resin drugs such as colestipol/cholestyramine). These products can react with indapamide, preventing its full absorption.
Use this medication regularly in order to get the most benefit from it. To help you remember, take it at the same time each day. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. It may take up to several weeks before the full benefit of this drug takes effect.
Do not stop taking this medication without first consulting your doctor. Some conditions may become worse when the drug is abruptly stopped. Your dose may need to be gradually decreased.
Inform your doctor if your condition worsens (e.g., your routine blood pressure readings increase or you have more swelling or feel more shortness of breath).
Indapamide may cause too much body water and salts to be lost (dehydration). Tell your doctor immediately if you have any of these unlikely but serious symptoms of dehydration: very dry mouth, thirst, muscle cramps, weakness, fast heartbeat, nausea, vomiting, severe dizziness, confusion, unusual decrease in the amount of urine, fainting, seizures.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor immediately if any of these unlikely but serious side effects occur: blurred vision, diarrhea, constipation, stomach pain, loss of appetite, weight loss, dizziness when standing, flushing, irregular heartbeat.
This drug may rarely cause serious liver or pancreas problems. Tell your doctor immediately if you notice any of the following rare but very serious side effects: yellowing of the eyes/skin, dark urine, severe stomach/abdominal pain, persistent tiredness, persistent nausea/vomiting.
Tell your doctor immediately if any of these rare but very serious side effects occur: signs of infection (e.g., fever, chills, persistent sore throat), easy bruising/bleeding, new/severe tiredness, breathing problems, weakness, bluish fingernails/lips, pale skin.
A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: rash, itching, swelling of any part of the face/neck, severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
Contact your doctor for medical advice about side effects. The following numbers do not provide medical advice, but in the US you may report side effects to the Food and Drug Administration (FDA) at 1-800-FDA-1088. In Canada, you may call Health Canada at 1-866-234-2345.
PRECAUTIONS: Before taking this product, tell your doctor or pharmacist if you are allergic to indapamide; or to thiazide diuretics (e.g., polythiazide, hydrochlorothiazide); or to sulfa medications; or if you have any other allergies.
This medication should not be used if you have certain medical conditions. Before using this medicine, consult your doctor or pharmacist if you have: an inability to make urine.
Before using this medication, tell your doctor or pharmacist your medical history, especially of: heart problems (e.g., congestive heart failure, QT prolongation in the EKG), kidney problems (e.g., kidney dialysis), liver disease, gout, diabetes, untreated mineral imbalance (e.g., high calcium, low potassium, low magnesium), loss of too much body water (dehydration), collagen vascular disease (e.g., lupus, scleroderma), recent nerve surgery (e.g., sympathectomy).
This drug may make you dizzy; use caution engaging in activities requiring alertness such as driving or using machinery. Limit alcoholic beverages.
To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
Drink plenty of fluids while taking this medication to help prevent dizziness. Too much sweating, diarrhea or vomiting may cause you to feel lightheaded. Avoid heavy exercise. Report prolonged diarrhea or vomiting to your doctor.
Before having surgery, tell your doctor or dentist that you are taking this medication.
This medication may make you more sensitive to the sun. Avoid prolonged sun exposure, tanning booths, and sunlamps. Use a sunscreen and wear protective clothing when outdoors.
This product may decrease your potassium levels. Before using potassium supplements or salt substitutes containing potassium, consult your doctor or pharmacist. If you have diabetes, this product may increase your blood sugar levels. Check your blood sugar levels regularly as directed by your doctor. Tell your doctor immediately if you have symptoms of high blood sugar, such as increased thirst and urination. Your anti-diabetic medication or diet may need to be adjusted.
Caution is advised when using this drug in the elderly because they may be more sensitive to its effects, especially dizziness.
This medication should be used only when clearly needed during pregnancy. Discuss the risks and benefits with your doctor.
It is not known if indapamide passes into breast milk. Since this drug could have undesirable effects on a nursing infant, breast-feeding while using this medication is not recommended. Consult your doctor before breast-feeding.
Your healthcare professionals (e.g., doctor or pharmacist) may already be aware of any possible drug interactions and may be monitoring you for it. Do not start, stop or change the dosage of any medicine before checking with them first.
This drug should not be used with the following medications because very serious interactions may occur: disopyramide, cisapride, bepridil.
Other drugs besides those listed above which may affect the heart rhythm (QTc prolongation in the EKG) include amiodarone, dofetilide, pimozide, guanidine, sotalol, procainamide, and erythromycin, among others. QTc prolongation can infrequently result in serious (rarely fatal) irregular heartbeats. Consult your doctor or pharmacist for more details, and for instructions on how you may minimize the risk of this effect.
Before using this medication, tell all your doctors or pharmacists of all prescription and nonprescription/herbal products you may use, especially of: drugs for diabetes (e.g., glyburide, insulin), aspirin, certain nonsteroidal anti-inflammatory drugs-NSAIDs (e.g., celecoxib, ibuprofen, indomethacin), diazoxide, digoxin, lithium, probenecid, drugs that may decrease your potassium level (e.g., amphotericin B, corticotropin, corticosteroids including prednisone), drugs whose removal from the body is affected by the acid level of urine (e.g., amphetamine, methenamine, quinidine).
Check the labels on all your medicines (e.g., cough-and-cold products, diet aids, nonsteroidal anti-inflammatory drugs-NSAIDs for pain/fever reduction) because they may contain ingredients that could increase your blood pressure or cause a fast heartbeat (e.g., pseudoephedrine, phenylephrine, chlorpheniramine, diphenhydramine, clemastine, ibuprofen, naproxen). Ask your pharmacist about the safe use of those products.
This product can affect the results of certain lab tests (e.g., parathyroid, certain tests that measure digoxin drug levels). Make sure laboratory personnel and all your doctors know you use this drug.
This document does not contain all possible interactions. Therefore, before using this product, tell your doctor or pharmacist of all the products you use. Keep a list of all your medications with you, and share the list with your doctor and pharmacist.
