What is Edarbyclor?

From the FDA label:Edarbyclor is a combination of azilsartan medoxomil (angiotensin II receptor blocker; as its potassium salt) and chlorthalidone (thiazide-like diuretic). Azilsartan medoxomil, a prodrug, is hydrolyzed to azilsartan in the gastrointestinal tract during absorption. Azilsartan is an angiotensin II receptor blocker. Chlorthalidone is a monosulfamyl thiazide-like diuretic that differs chemically from thiazide diuretics by the lack of a benzothiadiazine structure. The potassium salt of azilsartan medoxomil, azilsartan kamedoxomil, is chemically described as (5-Methyl-2-oxo-1,3-dioxol-4-yl)methyl 2-ethoxy-1-{[2'-(5-oxo-4,5-dihydro-1,2,4-oxadiazol-3-yl)biphenyl-4-yl]methyl}-1 H -benzimidazole-7-carboxylate monopotassium salt. Its empirical formula is C 30 H 23 KN 4 O 8. Chlorthalidone is chemically described as 2-chloro-5(1-hydroxy-3-oxo-1- isoindolinyl) benzenesulfonamide. Its empirical formula is C 14 H 11 ClN 2 O 4 S. The structural formula for azilsartan medoxomil is The structural formula for chlorthalidone is Azilsartan kamedoxomil is a white to nearly white powder with a molecular weight of 606.62. It is practically insoluble in water and freely soluble in methanol. Chlorthalidone is a white to yellowish white powder with a molecular weight of 338.76. Chlorthalidone is practically insoluble in water, in ether, and in chloroform; soluble in methanol; slightly soluble in ethanol.…

How to use

Starting dose is 40/12.5 mg once daily ( 2.1 ) Edarbyclor may be used to provide additional blood pressure lowering for patients not adequately controlled on azilsartan medoxomil 80 mg or chlorthalidone 25 mg ( 2.1 ) Dose may be increased to 40/25 mg after 2 to 4 weeks as needed to achieve blood pressure goals ( 2.1 ) Maximal dose is 40/25 mg ( 2.1 ) May be administered with other antihypertensive agents ( 2.1 ) Edarbyclor may be administered with or without food ( 2.1 ) Replace volume in volume-depleted patients prior to use ( 2.2 ) 2.1 Dosing Information The recommended starting dose of Edarbyclor is 40/12.5 mg taken orally once daily. Most of the antihypertensive effect is apparent within 1 to 2 weeks. The dosage may be increased to 40/25 mg after 2 to 4 weeks as needed to achieve blood pressure goals. Edarbyclor doses above 40/25 mg are probably not useful. Patients titrated to the individual components (azilsartan medoxomil and chlorthalidone) may instead receive the corresponding dose of Edarbyclor. Edarbyclor may be administered with other antihypertensive agents as needed. 2.2 Prior to Dosing Correct any volume depletion prior to administration of Edarbyclor, particularly in patients with impaired renal function or those treated with high doses of diuretics [see Warnings and Precautions (5.2) ]. Patients who experience dose-limiting adverse reactions on chlorthalidone…

Side effects

The following potential adverse reactions with Edarbyclor, azilsartan medoxomil, or chlorthalidone and similar agents are included in more detail in the Warnings and Precautions section of the label: Fetal toxicity [see Warnings and Precautions (5.1) ] Hypotension in Volume- or Salt-Depleted Patients [see Warnings and Precautions (5.2) ] Impaired Renal Function [see Warnings and Precautions (5.3) ] Hypokalemia [see Warnings and Precautions (5.4) ] Hyperuricemia [see Warnings and Precautions (5.5) ] Most common adverse reactions (incidence ≥2%) are dizziness and fatigue ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Azurity Pharmaceuticals, Inc. at 1-800-461-7449 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience 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 the clinical trials of another drug and may not reflect the rates observed in practice. Edarbyclor has been evaluated for safety in more than 3900 patients with hypertension; more than 700 patients were treated for at least 6 months and more than 280 for at least 1 year. Adverse reactions have generally been mild and transient in nature. Common adverse reactions that occurred in the 8-week factorial design trial in at least 2% of Edarbyclor-treated patients…

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

When pregnancy is detected, discontinue Edarbyclor as soon as possible [see Warnings and Precautions (5.1) and Use in Specific Populations (8.1) ]. Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus [see Warnings and Precautions (5.1) and Use in Specific Populations (8.1) ]. WARNING: FETAL TOXICITY See full prescribing information for complete boxed warning. When pregnancy is detected, discontinue EDARBYCLOR 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

In patients with an activated renin-angiotensin-aldosterone system (RAAS), such as volume- and/or salt-depleted patients, Edarbyclor can cause excessive hypotension. Correct volume or salt depletion prior to administration of Edarbyclor ( 5.2 ) In patients with renal artery stenosis, Edarbyclor may cause renal failure ( 5.3 ) Monitor renal function in patients with renal impairment. Consider discontinuing Edarbyclor with progressive renal impairment ( 5.3 ) Monitor serum electrolytes periodically ( 5.4 ) 5.1 Fetal Toxicity Azilsartan medoxomil Edarbyclor can cause fetal harm when administered to a pregnant woman. 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 Edarbyclor as soon as possible [see Use in Specific Populations (8.1) ]. Chlorthalidone Thiazides cross the placental barrier and appear in cord blood. Adverse reactions include fetal or neonatal jaundice and thrombocytopenia. 5.2 Hypotension in Volume- or Salt-Depleted Patients In patients with an activated renin-angiotensin system, such as volume- or salt-depleted patients (e.g., those being treated with high doses of diuretics), symptomatic hypotension may occur after initiation of treatment with Edarbyclor. Such patients are probably not good candidates to start therapy with more than one drug; therefore, correct volume prior to administration of Edarbyclor. If hypotension does occur, the patient should be placed in the supine position and, if necessary, given an intravenous infusion of normal saline . A transient hypotensive response is not a contraindication to further treatment, which usually can be continued without difficulty once the blood pressure has stabilized. 5.3 Impaired Renal Function Edarbyclor Monitor for worsening renal function in patients with renal impairment. Consider withholding or discontinuing Edarbyclor if progressive renal impairment becomes evident . Azilsartan medoxomil As a consequence of inhibiting the renin-angiotensin system, changes in renal function may be anticipated in susceptible individuals treated with Edarbyclor. In patients whose renal function may depend on the activity of the renin-angiotensin system (e.g., patients with severe congestive heart failure, renal artery stenosis, or volume depletion), treatment with angiotensin-converting enzyme inhibitors and angiotensin receptor blockers has been associated with oliguria or progressive azotemia and rarely with acute renal failure and death. Similar results may be anticipated in patients treated with Edarbyclor [see Drug Interactions (7) , Use in Specific Populations (8.6) and Clinical Pharmacology (12.3) ]. In studies of ACE inhibitors in patients with unilateral or bilateral renal artery stenosis, increases in serum creatinine or blood urea nitrogen have been reported. There has been no long-term use of azilsartan medoxomil in patients with unilateral or bilateral renal artery stenosis, but similar results are expected. Chlorthalidone In patients with renal disease, chlorthalidone may precipitate azotemia. If progressive renal impairment becomes evident, as indicated by increased blood urea nitrogen, consider withholding or discontinuing diuretic therapy. 5.4 Serum Electrolyte Imbalances Thiazide diuretics can cause hyponatremia and hypokalemia. Drugs that inhibit the renin angiotensin system can cause hyperkalemia. Hypokalemia is a dose-dependent adverse reaction that may develop with chlorthalidone. Co-administration of digitalis may exacerbate the adverse effects of hypokalemia. Monitor serum electrolytes periodically. Edarbyclor attenuates chlorthalidone-associated hypokalemia. In patients with normal potassium levels at baseline, 1.7% of Edarbyclor-treated patients, 0.9% of azilsartan medoxomil-treated patients, and 13.4% of chlorthalidone-treated patients shifted to low potassium values (less than 3.4 mmol/L). 5.5 Hyperuricemia Chlorthalidone Hyperuricemia may occur or frank gout may be precipitated in certain patients receiving chlorthalidone or other thiazide diuretics.

Who should not take Edarbyclor

Edarbyclor is contraindicated in patients with anuria [see Warnings and Precautions (5.3) ]. Do not coadminister aliskiren-containing products with Edarbyclor in patients with diabetes [see Drug Interactions (7) ] . Anuria ( 4 ) Do not coadminister aliskiren-containing products with Edarbyclor in patients with diabetes ( 4 )

Overdose — what happens if you take too much

Limited data are available related to overdosage in humans. Azilsartan medoxomil Limited data are available related to overdosage in humans. During controlled clinical trials in healthy subjects, once daily doses up to 320 mg of azilsartan medoxomil were administered for 7 days and were well tolerated. In the event of an overdose, supportive therapy should be instituted as dictated by the patient's clinical status. Azilsartan is not dialyzable. Chlorthalidone Symptoms of acute overdosage include nausea, weakness, dizziness, and disturbances of electrolyte balance. The oral LD50 of the drug in the mouse and the rat is more than 25,000 mg/kg body weight. The minimum lethal dose (MLD) in humans has not been established. There is no specific antidote, but gastric lavage is recommended, followed by supportive treatment. Where necessary, this may include intravenous dextrose-saline with potassium, administered with caution.

Interactions

Renal clearance of lithium is reduced by diuretics, such as chlorthalidone increasing the risk of lithium toxicity ( 7 ) NSAIDS increase risk of renal dysfunction and interfere with antihypertensive effect ( 7 ) Dual inhibition of the renin-angiotensin system: Increased risk of renal impairment, hypotension, and hyperkalemia ( 7 ) Lithium: Increases in serum lithium concentrations and lithium toxicity ( 7 ) 7.1 Non-Steroidal Anti-Inflammatory Agents including Selective Cyclooxygenase-2 Inhibitors (COX-2 Inhibitors) In patients who are elderly, volume-depleted (including those on diuretic therapy), or who have compromised renal function, co-administration of NSAIDs, including selective COX-2 inhibitors, with angiotensin II receptor antagonists, including azilsartan, may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible. Monitor renal function periodically in patients receiving Edarbyclor and NSAID therapy. The antihypertensive effect of Edarbyclor may be attenuated by NSAIDs, including selective COX-2 inhibitors. 7.2 Dual Blockade of the Renin-Angiotensin System (RAS) Dual blockade of the RAS with angiotensin receptor blockers, ACE inhibitors, or aliskiren is associated with increased risks of hypotension, hyperkalemia, and changes in renal function (including acute renal failure) compared to monotherapy. Most patients receiving the combination of two RAS inhibitors do not obtain any additional benefit compared to monotherapy. In general, avoid combined use of RAS inhibitors. Closely monitor blood pressure, renal function and electrolytes in patients on Edarbyclor and other agents that affect the RAS. Do not coadminister aliskiren with Edarbyclor in patients with diabetes. Avoid use of aliskiren with Edarbyclor in patients with renal impairment (GFR <60 mL/min). 7.3 Lithium Increases in serum lithium concentrations and lithium toxicity have been reported during concomitant administration of lithium with angiotensin II receptor agonists. Lithium renal clearance is reduced by diuretics, such as chlorthalidone. Monitor serum lithium levels during concomitant use.

How long does Azilsartan Kamedoxomil and Chlorthalidone stay in your body?

The elimination half-life of azilsartan kamedoxomil and chlorthalidone is about 40 hours on average (the label reports a mean half-life of 40 hours after a 50–200 mg dose, and an elimination half-life of 53 hours after 50 mg and 60 hours after 100 mg) — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. This is an older-format label (CLINICAL PHARMACOLOGY, not a PLR §12.3), and it gives its numbers in two ways: a mean half-life of 40 hours across the 50–200 mg dose range, and dose-specific elimination half-lives of 53 hours (50 mg) and 60 hours (100 mg). Only one phase is described, so the figures above are the elimination values the label states — it does not report a separate distribution phase. No active metabolite is described: the label says chlorthalidone is largely excreted unchanged by the kidneys and that data on metabolites and non-renal elimination routes "have yet to be clarified." It is not a prodrug. Do not confuse the half-life with the duration of diuretic effect — the label describes diuresis beginning in about 2.6 hours and continuing up to 72 hours, which is a different measure. The label does NOT quantify how the half-life changes with age, kidney impairment, or liver impairment; it gives no geriatric or renal/hepatic pharmacokinetic numbers. It does warn that cumulative effects of the drug may develop in patients with impaired renal function, and to use caution in severe renal disease and in impaired hepatic function — but it does not state a half-life for those groups, so no number should be inferred for them.
