Benicar vs. Blood Pressure Medication Comparison Tool
Select a Medication to Compare with Benicar
Comparison Results
If you’ve been prescribed Benicar (olmesartan medoxomil) and are curious how it stacks up against other drugs that lower blood pressure, you’re in the right place. This guide walks through the science, the side‑effect profiles, cost factors, and real‑world tips so you can decide whether Benicar is the best fit or if another option might serve you better.
Key Takeaways
- Benicar is an ARB that blocks the effects of angiotensinII, leading to smooth muscle relaxation and lower blood pressure.
- Compared with other ARBs (Losartan, Valsartan, Irbesartan), Benicar offers similar efficacy but may have a slightly lower incidence of cough.
- ACE inhibitors (Lisinopril, Enalapril) are equally effective but often cause a dry cough in 5‑10% of patients.
- Calcium‑channel blockers like Amlodipine work via a different pathway and are useful when patients can’t tolerate ARBs or ACE inhibitors.
- Cost varies widely; generic olmesartan is generally cheaper than the brand name, while generic Losartan is usually the most affordable ARB.
How Benicar (Olmesartan) Works
Benicar belongs to the class of drugs called angiotensin II receptor blockers (ARBs). By binding to the AT1 receptor, it prevents angiotensin II-a potent vasoconstrictor-from tightening blood vessels. The result is relaxed arterial walls, reduced peripheral resistance, and ultimately lower systolic and diastolic pressures.
Key Comparison Criteria
When you line up Benicar against its peers, the most practical dimensions are:
- Mechanism of action: how each drug lowers pressure.
- Efficacy: average reduction in mmHg in clinical trials.
- Side‑effect profile: common and serious adverse events.
- Cost: typical monthly out‑of‑pocket expense in the U.S.
- Convenience: dosing frequency and need for lab monitoring.
Benicar vs. Other ARBs
ARBs share the same pathway, so differences are subtle. Below is a quick snapshot.
| Medication | Drug Class | Typical Dose | Main Side Effects | Avg Monthly Cost (US$) | Highlights |
|---|---|---|---|---|---|
| Benicar | ARB | 20‑40mg once daily | Dizziness, hyperkalaemia, rare sprue‑like enteropathy | 30‑45 (brand) / 12‑20 (generic) | Low cough risk, once‑daily dosing |
| Losartan | ARB | 50‑100mg daily | Dizziness, upper respiratory infection | d>15‑25 (generic) | Most studied ARB, inexpensive |
| Valsartan | ARB | 80‑320mg daily | Headache, fatigue | 20‑35 (generic) | Often combined with hydrochlorothiazide |
| Irbesartan | ARB | 150‑300mg daily | Diarrhoea, back pain | 25‑40 (generic) | Favoured for diabetic nephropathy |
All four ARBs achieve similar reductions-about 10‑12mmHg systolic on average. The choice often boils down to cost, formulary coverage, or personal tolerance to side effects like cough (more common with ACE inhibitors than ARBs).
Benicar vs. ACE Inhibitors
ACE inhibitors block the conversion of angiotensin I to angiotensin II. While equally potent, they tend to cause a dry, persistent cough in 5‑10% of patients, which can be a deal‑breaker.
Lisinopril (10‑40mg daily) and Enalapril (5‑20mg daily) are the most prescribed ACE inhibitors. Both are cheap (≈$10‑15/month generic) but require monitoring of kidney function and potassium, especially when combined with a diuretic.
When a patient experiences an ACE‑inhibitor cough, switching to Benicar usually resolves the symptom within weeks because ARBs do not affect bradykinin levels.
Benicar vs. Calcium‑Channel Blockers
Calcium‑channel blockers (CCBs) lower blood pressure by relaxing vascular smooth muscle through a different mechanism-blocking calcium entry into cells.
Amlodipine (5‑10mg daily) is the most common CCB. It’s well‑tolerated, but can cause peripheral edema in up to 15% of users. CCBs are especially helpful for isolated systolic hypertension in older adults.
If you can’t tolerate any ARB (e.g., due to the rare sprue‑like enteropathy linked to olmesartan), a CCB like amlodipine offers comparable BP control without affecting the renin‑angiotensin system.
Benicar vs. Thiazide Diuretics
Thiazide diuretics work by increasing sodium and water excretion, reducing plasma volume.
Hydrochlorothiazide (12.5‑25mg daily) is cheap (≈$5‑10/month) and often paired with an ARB or ACE inhibitor for additive effect. Main side effects include low potassium and elevated uric acid, which can trigger gout.
For patients with chronic kidney disease, combining Benicar with a low‑dose thiazide can improve control while limiting the high potassium risk seen with higher‑dose ARBs alone.
Choosing the Right Option for You
Here’s a quick decision flow you can discuss with your doctor:
- Do you have a history of cough or angio‑edema with ACE inhibitors? Yes → stick with an ARB like Benicar or one of its peers.
- Are you experiencing gastrointestinal symptoms (diarrhoea, weight loss) after starting olmesartan? Yes → consider switching to losartan or a CCB.
- Is cost the primary barrier? Yes → generic Losartan or generic Olmesartan (if covered) are the most affordable ARBs.
- Do you have chronic kidney disease or diabetes with proteinuria? Yes → olmesartan or irbesartan may offer kidney‑protective benefits.
- Are you over 65 with isolated systolic hypertension? Yes → a low‑dose CCB like amlodipine could be optimal.
Always pair medication decisions with lifestyle changes-low‑salt diet, regular exercise, weight management-and regular blood‑pressure monitoring.
Frequently Asked Questions
Can I take Benicar with a thiazide diuretic?
Yes. Combining an ARB like Benicar with a low‑dose thiazide (e.g., hydrochlorothiazide) is a common strategy to achieve better BP control while minimizing side‑effects. Your doctor will check potassium levels regularly.
Why does olmesartan sometimes cause a severe intestinal problem?
A rare condition called sprue‑like enteropathy has been linked to olmesartan. It presents as chronic diarrhoea, weight loss, and villous atrophy. The mechanism isn’t fully understood, but stopping the drug usually resolves symptoms.
Is Benicar safe during pregnancy?
No. ARBs, including olmesartan, are classified as pregnancy category D. They can harm the fetal cardiovascular system. Pregnant patients should switch to a medication deemed safe, such as methyldopa.
How quickly does Benicar lower my blood pressure?
Blood‑pressure reduction begins within 2‑4hours of the first dose, with the full effect reaching a plateau after about 2weeks of consistent daily use.
Can I switch from Benicar to another ARB without a wash‑out period?
Yes. ARBs have similar half‑lives and mechanisms, so a direct switch is usually safe. Your physician may adjust the dose to match the new drug’s potency.

After a thorough review of the pharmacological profile of olmesartan, it becomes evident that its binding affinity for the AT1 receptor is remarkably high; consequently, vasodilation ensues with a predictable reduction in systolic pressure. Moreover, the drug’s pharmacokinetics, characterized by a half‑life of approximately 13 hours, permit convenient once‑daily dosing, a feature often prized by clinicians. In addition, the absence of routine laboratory monitoring distinguishes it from many ACE inhibitors, thereby simplifying outpatient management. Nonetheless, one must remain vigilant for the rare but serious sprue‑like enteropathy, which, albeit infrequent, necessitates prompt discontinuation. Finally, the cost spectrum-from generic formulations near $12 per month to brand‑name versions approaching $45-warrants consideration within the broader context of patient affordability.
Anthony Cannon
The comparative efficacy of ARBs, including olmesartan, typically falls within a 10‑12 mmHg systolic reduction; this aligns with the data presented for losartan and valsartan. Cost‑effectiveness, however, often favors generic losartan.
