What is Tekturna?

From the FDA label:Tekturna contains aliskiren hemifumarate, adirect renin inhibitor. Aliskiren hemifumarate is chemically described as (2S,4S,5S,7S)-N-(2-carbamoyl-2-methylpropyl)-5-amino-4-hydroxy- 2,7-diisopropyl-8-[4-methoxy-3-(3-methoxypropoxy)phenyl]-octanamide hemifumarate and its structural formula is: Molecular formula: C 30 H 53 N 3 O 6 • 0.5 C 4 H 4 O 4 Aliskiren hemifumarate is a white to slightly yellowish crystalline powder with a molecular weight of 609.8 (free base- 551.8). It is soluble in phosphate buffer, n-octanol, and highly soluble in water. Tekturna is available as film-coated tablets, which contains 165.75 mg or 331.5 mg aliskiren hemifumerate (equivalent to 150 mg or 300 mg aliskiren) and the following excipients: crospovidone; magnesium stearate; microcrystalline cellulose; povidone; silica, colloidal anhydrous; hypromellose; macrogol; talc; iron oxide, black (E 172); iron oxide, red (E 172); titanium dioxide (E 171). Structural Formula

How to use

Starting dose (adults and pediatric patients): 150 mg once daily with a routine pattern with regard to meals. If blood pressure remains uncontrolled titrate up to 300 mg daily. ( 2.1 ) Majority of effect of given dose attained in 2 weeks. ( 2.1 ) 2.1 Recommended Dosage In adult patients and in pediatric patients weighing 50 kg or greater who are at least 6 years of age, the recommended starting dose of Tekturna is 150 mg once daily. In patients whose blood pressure is not adequately controlled, the daily dose may be increased to 300 mg once daily. Doses above 300 mg did not give an increased blood pressure response but resulted in an increased rate of diarrhea. The antihypertensive effect of a given dosage is substantially attained (85% to 90%) by 2 weeks. 2.2 Relationship to Meals Patients should establish a routine pattern for taking Tekturna with regard to meals. High-fat meals decrease absorption substantially [see Clinical Pharmacology ( 12.3 )].

Most common adverse reaction: diarrhea (incidence 2.3%) ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact LXO US Inc. at 1-844-800-8007 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience The following serious adverse reactions are discussed in greater detail in other sections of the label: Fetal Toxicity [see Warnings and Precautions ( 5.1 )] Anaphylactic Reactions and Head and Neck Angioedema [see Warnings and Precautions ( 5.3 )] Hypotension [see Warnings and Precautions ( 5.4 )] Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in clinical trials of another drug and may not reflect the rates observed in practice. Adult Hypertension Data described below reflect the evaluation of the safety of Tekturna in more than 6,460 patients, including over 1,740 treated for longer than 6 months, and more than 1,250 patients for longer than 1 year. In placebo-controlled clinical trials, discontinuation of therapy due to a clinical adverse event, including uncontrolled hypertension, occurred in 2.2% of patients treated with Tekturna versus 3.5%…

FDA Boxed Warning (the FDA’s most serious warning)

Boxed (black-box) warning — from the FDA label

When pregnancy is detected, discontinue Tekturna as soon as possible. ( 5.1 , 8.1 ) Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus. ( 5.1 , 8.1 ) WARNING: FETAL TOXICITY See full prescribing information for complete boxed warning. When pregnancy is detected, discontinue Tekturna as soon as possible. ( 5.1 , 8.1 ) Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus. ( 5.1 , 8.1 )

Warnings

Important safety information

Avoid concomitant use with ARBs or ACEIs particularly in patients with renal impairment [creatinine clearance (CrCl) <60 mL/min]. ( 5.2 , 5.4 ) Anaphylactic Reactions and Head and Neck Angioedema. ( 5.3 ) Hypotension: Correct imbalances in volume and/or salt depleted patients. ( 5.4 ) Impaired Renal Function: Monitor serum creatinine periodically. ( 5.5 ) Hyperkalemia: Monitor potassium levels periodically. ( 5.6 ) 5.1 Fetal Toxicity Use of drugs that act on the renin-angiotensin 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 Tekturna as soon as possible [see Use in Specific Populations ( 8.1 )]. 5.2 Renal Impairment/Hyperkalemia/Hypotension when Tekturna is Given in Combination with ARBs or ACEIs Tekturna is contraindicated in patients with diabetes who are receiving ARBs or ACEIs because of the increased risk of renal impairment, hyperkalemia, and hypotension. In general, avoid combined use of Tekturna with ACE inhibitors or ARBs, particularly in patients with creatinine clearance (CrCl) less than 60 mL/min [see Contraindications ( 4 ), Drug Interactions ( 7 ) and Clinical Studies ( 14.3 )] . 5.3 Anaphylactic Reactions and Head and Neck Angioedema Hypersensitivity reactions such as anaphylactic reactions and angioedema of the face, extremities, lips, tongue, glottis and/or larynx have been reported in patients treated with Tekturna and has necessitated hospitalization and intubation. This may occur at any time during treatment and has occurred in patients with and without a history of angioedema with ACEIs or angiotensin receptor antagonists. Anaphylactic reactions have been reported from postmarketing experience with unknown frequency. If angioedema involves the throat, tongue, glottis or larynx, or if the patient has a history of upper respiratory surgery, airway obstruction may occur and be fatal. Patients who experience these effects, even without respiratory distress, require prolonged observation and appropriate monitoring measures since treatment with antihistamines and corticosteroids may not be sufficient to prevent respiratory involvement. Prompt administration of subcutaneous epinephrine solution 1:1000 (0.3 mL to 0.5 mL) and measures to ensure a patent airway may be necessary. Discontinue Tekturna immediately in patients who develop anaphylactic reactions or angioedema, and do not readminister [see Dosage and Administration ( 2.1 ) and Contraindications ( 4 )]. 5.4 Hypotension Symptomatic hypotension may occur after initiation of treatment with Tekturna in patients with marked volume depletion, patients with salt depletion, or with combined use of Tekturna and other agents acting on the renin-angiotensin-aldosterone system (RAAS). The volume or salt depletion should be corrected prior to administration of Tekturna, or the treatment should start under close medical supervision. A transient hypotensive response is not a contraindication to further treatment, which usually can be continued without difficulty once the blood pressure has stabilized. 5.5 Impaired Renal Function Monitor renal function periodically in patients treated with Tekturna. Changes in renal function, including acute renal failure, can be caused by drugs that affect the RAAS. Patients whose renal function may depend in part on the activity of the RAAS (e.g., patients with renal artery stenosis, severe heart failure, post-myocardial infarction or volume depletion) or patients receiving ARB, ACEI or nonsteroidal anti-inflammatory drug (NSAID), including selective Cyclooxygenase-2 inhibitors (COX-2 inhibitors), therapy may be at particular risk for developing acute renal failure on Tekturna [see Warnings and Precautions ( 5.2 ), Drug Interactions ( 7 ), Use in Specific Populations ( 8.6 ), and Clinical Studies ( 14.3 )] . Consider withholding or discontinuing therapy in patients who develop a clinically significant decrease in renal function. 5.6 Hyperkalemia Monitor serum potassium periodically in patients receiving Tekturna. Drugs that affect the RAAS can cause hyperkalemia. Risk factors for the development of hyperkalemia include renal insufficiency, diabetes, combination use with ARBs or ACEIs [see Contraindications ( 4 ), Warnings and Precautions ( 5.2 ), and Clinical Studies ( 14.3 )] , NSAIDs, or potassium supplements or potassium sparing diuretics. 5.7 Cyclosporine or Itraconazole When Tekturna was given with cyclosporine or itraconazole, the blood concentrations of aliskiren were significantly increased. Avoid concomitant use of Tekturna with cyclosporine or itraconazole [see Drug Interactions ( 7 )] .

Who should not take Tekturna

Do not use Tekturna with ARBs or ACEIs in patients with diabetes [see Warnings and Precautions ( 5.2 ) and Clinical Studies ( 14.3 )]. Tekturna is contraindicated in patients with known hypersensitivity to any of the components [see Warnings and Precautions ( 5.3 )]. Tekturna is contraindicated in pediatric patients less than 2 years of age because of the risk of high aliskiren exposures identified in juvenile animals due to immaturity of transporters and metabolic enzymes [see Use in Specific Populations ( 8.4 )]. Do not use with angiotensin receptor blockers (ARBs) or angiotensin- converting enzyme inhibitors (ACEIs) in patients with diabetes. ( 4 ) Hypersensitivity to any of the components. ( 4 ) Tekturna is contraindicated in pediatric patients less than 2 years of age. ( 4 )

Overdose — what happens if you take too much

Limited data are available related to overdosage in humans. The most likely manifestation of overdosage would be hypotension. If symptomatic hypotension occurs, supportive treatment should be initiated. Aliskiren is poorly dialyzed. Therefore, hemodialysis is not adequate to treat aliskiren overexposure [see Clinical Pharmacology ( 12.3 )] .

Interactions

Cyclosporine: Avoid coadministration of cyclosporine with aliskiren [see Warnings and Precautions ( 5.7 ) and Clinical Pharmacology ( 12.3 )] . Itraconazole: Avoid coadministration of itraconazole with aliskiren [see Warnings and Precautions ( 5.7 ) and Clinical Pharmacology ( 12.3 )]. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) including selective Cyclooxygenase-2 inhibitors (COX-2 inhibitors): In patients who are elderly, volume-depleted (including those on diuretic therapy), or with compromised renal function, coadministration of NSAIDs, including selective COX-2 inhibitors with agents that affect the RAAS, including aliskiren, may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible. Monitor renal function periodically in patients receiving aliskiren and NSAID therapy. The antihypertensive effect of aliskiren may be attenuated by NSAIDs. Dual Blockade of the Renin-Angiotensin-Aldosterone System (RAAS): The concomitant use of aliskiren with other agents acting on the RAAS such as ACEIs or ARBs is associated with an increased risk of hypotension, hyperkalemia, and changes in renal function (including acute renal failure) compared to monotherapy. Most patients receiving the combination of two drugs that inhibit the renin-angiotensin system do not obtain any additional benefit compared to monotherapy. In general, avoid combined use of aliskiren with ACE inhibitors or ARBs, particularly in patients with CrCl less than 60 mL/min. Monitor blood pressure, renal function, and electrolytes in patients taking aliskiren and other agents that affect the RAAS [see Warnings and Precautions ( 5.4 , 5.5 , 5.6 )]. The concomitant use of aliskiren with an ARB or an ACEI in diabetic patients is contraindicated [see Contraindications ( 4 )]. Furosemide: Oral coadministration of aliskiren and furosemide reduced exposure to furosemide. Monitor diuretic effects when furosemide is coadministered with aliskiren. Cyclosporine or Itraconazole: Avoid concomitant use. ( 5.7 , 7 , 12.3 ) Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Increased risk of renal impairment and loss of antihypertensive effect. ( 7 )
