What is Benicar?

From the FDA label:Olmesartan medoxomil, a prodrug, is hydrolyzed to olmesartan during absorption from the gastrointestinal tract. Olmesartan is a selective AT 1 subtype angiotensin II receptor antagonist. Olmesartan medoxomil is described chemically as 2,3-dihydroxy-2-butenyl 4-(1-hydroxy-1-methylethyl)-2-propyl-1-[ p -( o -1 H -tetrazol-5-ylphenyl)benzyl]imidazole-5-carboxylate, cyclic 2,3-carbonate. Its empirical formula is C 29 H 30 N 6 O 6 and its structural formula is: Olmesartan medoxomil is a white to light yellowish-white powder or crystalline powder with a molecular weight of 558.59. It is practically insoluble in water and sparingly soluble in methanol. Benicar is available for oral use as film-coated tablets containing 5 mg, 20 mg, or 40 mg of olmesartan medoxomil and the following inactive ingredients: hydroxypropyl cellulose, hypromellose, lactose monohydrate, low-substituted hydroxypropyl cellulose, magnesium stearate, microcrystalline cellulose, talc, titanium dioxide, and (5 mg only) yellow iron oxide.

How to use

Indication Starting Dose Dose Range Adult Hypertension ( 2.1 ) 20 mg once daily 20 - 40 mg once daily Pediatric Hypertension (6 years of age and older) ( 2.2 ) 20 to <35 kg 20 to <35 kg 10 mg once daily 10 - 20 mg once daily ≥ 35 kg ≥ 35 kg 20 mg once daily 20 - 40 mg once daily 2.1 Adult Hypertension Dosage must be individualized. The usual recommended starting dose of Benicar is 20 mg once daily when used as monotherapy in patients who are not volume-contracted. For patients requiring further reduction in blood pressure after 2 weeks of therapy, the dose of Benicar may be increased to 40 mg. Doses above 40 mg do not appear to have greater effect. Twice-daily dosing offers no advantage over the same total dose given once daily. For patients with possible depletion of intravascular volume (e.g., patients treated with diuretics, particularly those with impaired renal function), initiate Benicar under close medical supervision and give consideration to use of a lower starting dose [see Warnings and Precautions (5.3) ] . 2.2 Pediatric Hypertension (6 Years of Age and Older) Dosage must be individualized. For children who can swallow tablets, the usual recommended starting dose of Benicar is 10 mg once daily for patients who weigh 20 to <35 kg (44 to 77 lb), or 20 mg once daily for patients who weigh ≥35 kg. For patients requiring further reduction in blood pressure after 2 weeks…

Side effects

The most common adverse reaction in adults was dizziness (3%) ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact Cosette Pharmaceuticals, Inc. at 1-800-922-1038 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. Adult Hypertension Benicar has been evaluated for safety in more than 3825 patients/subjects, including more than 3275 patients treated for hypertension in controlled trials. This experience included about 900 patients treated for at least 6 months and more than 525 for at least 1 year. Events generally were mild, transient and had no relationship to the dose of Benicar. Analysis of gender, age and race groups demonstrated no differences between Benicar and placebo-treated patients. The rate of withdrawals due to adverse reactions in all trials of hypertensive patients was 2.4% (i.e., 79/3278) of patients treated with Benicar and 2.7% (i.e., 32/1179) of control patients. In placebo-controlled trials, the only adverse reaction that occurred in more than 1% of patients treated with Benicar and at a higher incidence versus placebo was dizziness (3% vs. 1%). Facial edema was…

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

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

When pregnancy is detected, discontinue Benicar 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 Benicar 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 fetal ( in utero ) exposure ( 5.1 ). Use of Benicar in children <1 year of age is not recommended ( 5.2 ). Observe for signs and symptoms of hypotension in volume- or salt-depleted patients with treatment initiation ( 5.3 ). Monitor for worsening renal function in patients with renal impairment ( 5.4 ). Sprue-like enteropathy has been reported. Consider alternative antihypertensive therapy in cases where no other etiology is found ( 5.5 ). 5.1 Fetal Toxicity Benicar can cause fetal harm when administered to a pregnant woman. Use of drugs that act on the renin-angiotensin system (RAS) 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 Benicar as soon as possible [see Use in Specific Populations (8.1) ]. 5.2 Morbidity in Infants Use of Benicar in children <1 year of age is not recommended. Drugs that act directly on the renin-angiotensin-aldosterone system (RAAS) can have effects on the development of immature kidneys [see Use in Specific Populations (8.4) ]. 5.3 Hypotension in Volume- or Salt-Depleted Patients In patients with an activated renin-angiotensin-aldosterone system, such as volume- and/or salt-depleted patients (e.g., those being treated with high doses of diuretics), symptomatic hypotension may be anticipated after initiation of treatment with Benicar. Initiate treatment under close medical supervision and consider starting at a lower dose. If hypotension does occur, place the patient in the supine position and, if necessary, give an intravenous infusion of normal saline [see Dosage and Administration (2.1) ] . A transient hypotensive response is not a contraindication to further treatment, which usually can be continued without difficulty once the blood pressure has stabilized. 5.4 Impaired Renal Function As a consequence of inhibiting the renin-angiotensin-aldosterone system, changes in renal function may be anticipated in susceptible individuals treated with Benicar. In patients whose renal function may depend upon the activity of the renin-angiotensin-aldosterone system (e.g., patients with severe congestive heart failure), treatment with angiotensin converting enzyme (ACE) inhibitors and angiotensin receptor antagonists has been associated with oliguria and/or progressive azotemia and rarely with acute renal failure and/or death. Similar results may be anticipated in patients treated with Benicar [see Dosage and Administration (2.1) , Drug Interactions (7.3) , Use in Specific Populations (8.7) 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 (BUN) have been reported. There has been no long-term use of Benicar in patients with unilateral or bilateral renal artery stenosis, but similar results may be expected. 5.5 Sprue-like Enteropathy Severe, chronic diarrhea with substantial weight loss has been reported in patients taking olmesartan months to years after drug initiation. Intestinal biopsies of patients often demonstrated villous atrophy. If a patient develops these symptoms during treatment with olmesartan, exclude other etiologies. Consider alternative antihypertensive therapy in cases where no other etiology is identified. 5.6 Hyperkalemia Serum potassium should be monitored in patients receiving Benicar. Drugs that inhibit the renin angiotensin system can cause hyperkalemia. Risk factors for the development of hyperkalemia include renal insufficiency, diabetes mellitus, and the concomitant use of potassium-sparing diuretics, potassium supplements and/or potassium-containing salt substitutes [see Drug Interactions (7.3) ] .

Who should not take Benicar

Do not co-administer aliskiren with Benicar in patients with diabetes [see Drug Interactions (7.3) ]. Do not co-administer aliskiren with Benicar in patients with diabetes ( 4 ).

Overdose — what happens if you take too much

Limited data are available related to overdosage in humans. The most likely manifestations of overdosage would be hypotension and tachycardia; bradycardia could be encountered if parasympathetic (vagal) stimulation occurs. If symptomatic hypotension occurs, initiate supportive treatment. The dialyzability of olmesartan is unknown.

Interactions

Agents increasing potassium levels may lead to increase in serum potassium ( 7.1 ). NSAID use may lead to increased risk of renal impairment and loss of antihypertensive effect ( 7.2 ). Dual inhibition of the renin-angiotensin system: Increased risk of renal impairment, hypotension, and hyperkalemia ( 7.3 ). Lithium: Increases in serum lithium concentrations and lithium toxicity ( 7.4 ). Colesevelam hydrochloride: Consider administering olmesartan at least 4 hours before colesevelam hydrochloride dose ( 7.5 ). 7.1 Agents Increasing Serum Potassium Concomitant use of olmesartan with other agents that block the renin-angiotensin system, potassium-sparing diuretics (e.g., spironolactone, triamterene, amiloride), potassium supplements, salt substitutes containing potassium or other drugs that may increase potassium levels (e.g., heparin) may lead to increases in serum potassium. If co-medication is considered necessary, monitoring of serum potassium is advisable. 7.2 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 with compromised renal function, co-administration of NSAIDs, including selective COX-2 inhibitors, with angiotensin II receptor antagonists, including olmesartan medoxomil, may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible. Monitor renal function periodically in patients receiving olmesartan medoxomil and NSAID therapy. The antihypertensive effect of angiotensin II receptor antagonists, including olmesartan medoxomil, may be attenuated by NSAIDs including selective COX-2 inhibitors. 7.3 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 Benicar and other agents that affect the RAS. Do not co-administer aliskiren with Benicar in patients with diabetes [see Contraindications (4) ]. Avoid use of aliskiren with Benicar in patients with renal impairment (GFR <60 ml/min). 7.4 Lithium Increases in serum lithium concentrations and lithium toxicity have been reported during concomitant administration of lithium with angiotensin II receptor antagonists, including BENICAR. Monitor serum lithium levels during concomitant use. 7.5 Colesevelam Hydrochloride Concurrent administration of bile acid sequestering agent colesevelam hydrochloride reduces the systemic exposure and peak plasma concentration of olmesartan. Administration of olmesartan at least 4 hours prior to colesevelam hydrochloride decreased the drug interaction effect. Consider administering olmesartan at least 4 hours before the colesevelam hydrochloride dose [see Clinical Pharmacology (12.3) ] .

Frequently asked questions

What does Benicar treat?
Benicar (Olmesartan Medoxomil) may be used to treat diabetic nephropathies, heart failure, hypertension, left ventricular dysfunction, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.
How does Benicar work?
Benicar is a angiotensin 2 receptor blocker. Angiotensin II receptor blockers (ARBs) block the AT1 receptor that the hormone angiotensin II uses to tighten blood vessels and make the body hold onto salt and water. With that receptor blocked, vessels relax and widen, so blood pressure falls.
How is Benicar rated?
pharmaranks gives Benicar a composite score of 3.5 out of 5, currently based on 1 weighted source (FDA regulatory recall-safety data weighted highest). See our methodology at /how-we-rate.
How much does Benicar cost?
Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $2.24 for 30, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins. Pharmacies pay less for a same-class option, Arbli — about $1.00 on the same basis.
Is there a coupon or discount for Benicar?
pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Benicar. To pay less, ask your prescriber or pharmacist whether a generic equivalent exists, check the manufacturer's copay/savings card and patient-assistance program, and compare a pharmacy discount card against your insurance copay. Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.
