Olmesartan medoxomil is an angiotensin II receptor antagonist which has been used for the treatment
of high blood pressure.
It was developed by Sankyo in 1995, and is sold under the trade name Benicar and Olmecip (Cipla).
An ester prodrug, it is completely and rapidly hydrolyzed to the active acid form, olmesartan (RNH-6270)
The U.S. Food and Drug Administration (FDA) has determined that the benefits of Benicar continue to
outweigh its potential risks when used for the treatment of patients with high blood pressure according
to the drug label.

Bioavailability 26%
Metabolism Hepatic (cannot be removed by hemodialysis)
Half-life 13 hours
Excretion Renal 40%, biliary 60%

5. 5
Clinical uses
Used to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes,
heart attacks, and kidney problems.
Olmesartan belongs to a class of drugs called angiotensin receptor blockers (ARBs). It works by relaxing
blood vessels so that blood can flow more easily.
This medication is also used to treat heart failure.
Unlike many angiotensin II receptor blockers, olmesartan is not recommended as a treatment to delay
or prevent microalbuminuria in diabetic patients.
Side effect
Dizziness or lightheadedness may occur as your body adjusts to the medication.
To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying
position.
It should be remembered that the doctor has prescribed this medication because he or she has judged
that the benefit is greater than the risk of side effects. Many people using this medication do not have
serious side effects.
Advised to tell the doctor right away if one has any serious side effects, including: fainting, symptoms of
a high potassium blood level (such as muscle weakness, slow/irregular heartbeat), unusual decrease in
the amount of urine, severe/persistent diarrhea...
Precautions
Before taking olmesartan, it is advised to tell the doctor or pharmacist if he is allergic to it; or if he has
any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or
other problems.
Before using this medication, advised to tell the doctor or pharmacist his medical history, especially of:
kidney disease, liver disease, severe loss of body water and minerals (dehydration).
This drug may make him dizzy. Not advised to drive, use machinery, or do any activity that requires
alertness until he/ she is sure he/ she can perform such activities safely. Limit alcoholic beverages.
This medication may increase the potassium levels. Before using potassium supplements or salt
substitutes that contain potassium, advised to consult the doctor.
This medication is not recommended for use during pregnancy due to the risk for harm to an unborn
baby.

6. Interactions
Drug interactions may change how one’s medications work or increase your risk for serious side effects.
Some products that may interact with this drug include: aliskiren, lithium, drugs that may increase the
level of potassium in the blood (such as ACE inhibitors including benazepril/lisinopril, birth control pills
containing drospirenone).

Other antihypertensives
Alpha-Blockers (Antihypertensive)
Alpha blockers, also called alpha-adrenergic antagonists, dilate blood vessels by blocking postsynaptic
alpha1-adrenergic receptors. Alpha blockers are generally not recommended as initial therapy.
Generic Brand Name
Doxazosin Cardura, Carduran
Prazosin Minipress, Minipress XL
Terazosin Hytrin
Alpha-2 Agonists, Central-Acting
Alpha-2 agonists work by stimulating alpha-2 receptors and decreasing sympathetic activity, which leads
to decreased blood pressure and heart rate.

Comparative pharmacokinetics of ARBs
Characteristics and labeled indications ARBs
There are currently seven ARBs in the market

16. 16

17. 17
Mechanisms of antagonism
The mechanisms of antagonism also vary between the ARBs: some show insurmountable antagonism
(e.g. candesartan) and others show surmountable antagonism (e.g. losartan). Insurmountable
antagonism is characterised by long-lasting inhibition, slow dissociation, irreversible binding,
conformational changes and potentially internalisation, whereas surmountable antagonism is
characterised by short-lasting inhibition and fast, reversible binding.
Losartan only binds at two angiotensin II type 1 receptor (AT1) sites, compared to candesartan which
shows high binding affinity at four sites.2 It is suggested that the tight binding and slow dissociation of
candesartan from the AT1 receptor may account for the magnitude of the antihypertensive efficacy of
candesartan and for its long duration of action, inducing long-lasting suppression of the RAAS.
Key properties of ARB’s
Losartan: The only medicine in its class proven to lower the chance of stroke.
Only ARB that has been shown to reduce serum uric acid levels.
Only ARB approved by the FDA for treating nephropathy in patients withT2DM
Valsartan First ARB to receive approval in Heart Failure
Reverses ventricular remodeling and Improves survival outcome in HF
Telmisartan Highly selective inhibition of the angiotensin II receptor 1 (AT1)
Has the longest plasma half-life and largest volume of distribution of any ARB
Powerful 24-hour action, curbing the morning surge in blood pressure
compared to other leading ARB’s Has PPAR-gamma activity and hence improves Insulin
sensitivity
Olmesartan Significant mean double-digit blood pressure (BP) reductions vs baseline at
the starting dose

PATENT SCENARIO
Patent expiry on ‘Benicar’ –(Daiichi Sankyo) October 2016
Mylan Pharmaceuticals ($MYL) has won the right to sell the drug exclusively for the first 180 days after
the patent expires on the blockbuster.
Still, both companies may face competition sooner than they thought. In November 2012, Apotex
petitioned a U.S. court to rule that its Benicar generic wouldn't infringe patent rights. A finding of
noninfringement, Apotex said, would let it compete with Mylan sooner. But Apotex has yet to get its
own drug approved by the FDA.
Benicar's patent doesn't expire till 2016, but it's already feeling the pressure from generic drug makers
that think they can push their copies to market sooner.
