Warnings
5 WARNINGS AND PRECAUTIONS Hypotension: Correct volume depletion prior to initiation ( 5.2 ) Electrolyte and Glucose Imbalances: Monitor serum electrolytes and glucose ( 5.3 ) Impaired Renal Function: Monitor renal function ( 5.4 ) Acute angle closure glaucoma can develop ( 5.5 ) Hyperuricemia may occur ( 5.6 ) 5.1 Fetal Toxicity Use of drugs that act on the renin-angiotensin-aldosterone system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. Resulting oligohydramnios can be associated with fetal lung hypoplasia and skeletal deformations. Potential neonatal adverse effects include skull hypoplasia, anuria, hypotension, renal failure, and death. When pregnancy is detected, discontinue Widaplik as soon as possible [see Use in Specific Populations ( 8.1 ) ]. 5.2 Hypotension Widaplik can cause symptomatic hypotension. Patients with hypovolemia, salt depletion, or aortic stenosis are at increased risk. Monitor blood pressure and adjust dose as needed. Hypotension leading to worsening angina and acute myocardial infarction can develop after starting or increasing the dose of Widaplik because of the amlodipine component, particularly in patients with severe obstructive coronary artery disease. 5.3 Electrolyte and Glucose Imbalances Thiazide-like diuretics can cause hyponatremia, hypomagnesemia and hypokalemia and can also alter serum glucose and affect insulin requirements. Drugs that inhibit the renin angiotensin-aldosterone system can cause hyperkalemia. Patients with renal impairment or heart failure are at increased risk for hyperkalemia. Monitor serum electrolytes and glucose periodically. 5.4 Impaired Renal Function Inhibiting the renin-angiotensin-aldosterone system or diuresis can precipitate renal dysfunction, oliguria and acute renal failure. Patients with severe congestive heart failure or renal dysfunction are at increased risk [see Clinical Pharmacology ( 12.3 ) ]. Monitor renal function periodically and adjust dose as needed. 5.5 Acute Angle-Closure Glaucoma, Acute Myopia, and Choroidal Effusion Sulfonamide or sulfonamide-derivative drugs, like indapamide, can cause an idiosyncratic reaction resulting in acute angle-closure glaucoma and elevated intraocular pressure with or without a noticeable acute myopic shift and/or choroidal effusions. Symptoms may include acute onset of decreased visual acuity or ocular pain and typically occur within hours to weeks of drug initiation. Untreated, the angle-closure glaucoma may result in permanent visual field loss. The primary treatment is to discontinue Widaplik as rapidly as possible. Prompt medical or surgical treatments may need to be considered if the intraocular pressure remains uncontrolled. Risk factors for developing acute angle-closure glaucoma may include a history of sulfonamide or penicillin allergy. 5.6 Hyperuricemia Hyperuricemia may occur or frank gout may be precipitated in certain patients receiving thiazide-like diuretics.

Overdose
10 OVERDOSAGE Telmisartan Limited data are available with regard to overdosage in humans. The most likely manifestations of overdosage would be hypotension, dizziness, and tachycardia; bradycardia could occur from parasympathetic (vagal) stimulation. If symptomatic hypotension should occur, supportive treatment should be instituted. Telmisartan is not removed by hemodialysis. Amlodipine Overdosage might be expected to cause excessive peripheral vasodilation with marked hypotension and possibly a reflex tachycardia. In humans, experience with intentional overdosage of amlodipine is limited. Marked and potentially prolonged systemic hypotension up to and including shock with fatal outcome have been reported. Single oral doses of amlodipine maleate equivalent to 40 mg amlodipine/kg and 100 mg amlodipine/kg in mice and rats, respectively, caused deaths. Single oral amlodipine maleate doses equivalent to 4 or more mg amlodipine/kg or higher in dogs (11 or more times the MRHD on a mg/m 2 basis) caused a marked peripheral vasodilation and hypotension. If massive overdose should occur, initiate active cardiac and respiratory monitoring. Frequent blood pressure measurements are essential. Should hypotension occur, provide cardiovascular support including elevation of the extremities and the judicious administration of fluids. If hypotension remains unresponsive to these conservative measures, consider administration of vasopressors (such as phenylephrine) with attention to circulating volume and urine output. As amlodipine is highly protein bound, hemodialysis is not likely to be of benefit. Administration of activated charcoal to healthy volunteers immediately or up to two hours after ingestion of amlodipine has been shown to significantly decrease amlodipine absorption. Indapamide Symptoms of overdosage of indapamide 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.

Uses
1 INDICATIONS AND USAGE Widaplik (telmisartan/amlodipine/indapamide) is indicated for the treatment of hypertension in adult patients, to lower blood pressure. Widaplik may be used as initial therapy in patients likely to need multiple drugs to achieve blood pressure goals. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes including angiotensin II receptor blockers, dihydropyridine calcium channel blockers and thiazide-like diuretics. There are no controlled trials demonstrating risk reduction with Widaplik. Control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than one drug to achieve blood pressure goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program’s Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC). Numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action, have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is blood pressure reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. The largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of stroke, but reductions in myocardial infarction and cardiovascular mortality also have been seen regularly. Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmHg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension (for example, patients with diabetes or hyperlipidemia), and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal. Some antihypertensive drugs have smaller blood pressure effects (as monotherapy) in black patients, and many antihypertensive drugs have additional approved indications and effects (e.g., on angina, heart failure, or diabetic kidney disease). These considerations may guide selection of therapy. Patients with moderate or severe hypertension are at relatively high risk for cardiovascular events (such as strokes, heart attacks, and heart failure), kidney failure, and vision problems, so prompt treatment is clinically relevant. Consider the patient's baseline blood pressure, the target goal, and the incremental likelihood of achieving the goal with a triple combination product compared with mono- or dual therapy when deciding whether to use Widaplik as initial therapy. Individual blood pressure goals may vary based upon the patient’s risk. WIDAPLIK is a combination tablet of telmisartan, an angiotensin II receptor blocker, amlodipine, a dihydropyridine calcium channel blocker and indapamide, a thiazide-like diuretic. Widaplik is indicated for the treatment of hypertension, including as initial treatment, to lower blood pressure.
