Olmesartan

Name: Olmesartan

Olmesartan and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Olmesartan falls into category D. There is evidence of risk to the unborn baby based on studies in humans or adverse reaction data. This medication may be given to a pregnant woman if her healthcare provider believes that the benefits to the pregnant woman outweigh any possible risks to her unborn baby.

Olmesartan and Lactation

Tell your doctor if you are breastfeeding or plan to breastfeed.

It is not known if olmesartan is excreted in human breast milk or if it will harm your nursing baby.

If you take too much this medication, call your healthcare provider or local Poison Control Center, or seek emergency medical attention right away.

If this medication is administered by a healthcare provider in a medical setting, it is unlikely that an overdose will occur. However, if overdose is suspected, seek emergency medical attention.

Warnings/Precautions

Concerns related to adverse effects:

• Angioedema: Angioedema has been reported rarely with some angiotensin II receptor antagonists (ARBs) and may occur at any time during treatment (especially following first dose). It may involve the head and neck (potentially compromising airway) or the intestine (presenting with abdominal pain). Patients with idiopathic or hereditary angioedema or previous angioedema associated with ACE-inhibitor therapy may be at an increased risk. Prolonged frequent monitoring may be required, especially if tongue, glottis, or larynx are involved, as they are associated with airway obstruction. Patients with a history of airway surgery may have a higher risk of airway obstruction. Discontinue therapy immediately if angioedema occurs. Aggressive early management is critical. Intramuscular (IM) administration of epinephrine may be necessary. Do not readminister to patients who have had angioedema with ARBs.

• Gastrointestinal effects: Symptoms of sprue-like enteropathy (ie, severe, chronic diarrhea with significant weight loss) has been reported; may develop months to years after treatment initiation with villous atrophy commonly found on intestinal biopsy. Once other etiologies have been excluded, discontinue treatment and consider other antihypertensive treatment. Clinical and histologic improvement was noted after treatment was discontinued in a case series of 22 patients (Ianiro, 2014; Rubio-Tapia, 2012).

• Hyperkalemia: May occur; risk factors include renal dysfunction, diabetes mellitus, concomitant use of potassium-sparing diuretics, potassium supplements and/or potassium containing salts. Use cautiously, if at all, with these agents and monitor potassium closely.

• Hypotension: Symptomatic hypotension may occur upon initiation in patients who are salt- or volume-depleted (eg, those treated with high-dose diuretics); correct volume depletion prior to administration. This transient hypotensive response is not a contraindication to further treatment with olmesartan.

• Renal function deterioration: May be associated with deterioration of renal function and/or increases in serum creatinine, particularly in patients with low renal blood flow (eg, renal artery stenosis, heart failure) whose glomerular filtration rate (GFR) is dependent on efferent arteriolar vasoconstriction by angiotensin II; deterioration may result in oliguria, acute renal failure, and progressive azotemia. Small increases in serum creatinine may occur following initiation; consider discontinuation only in patients with progressive and/or significant deterioration in renal function.

Disease-related concerns:

• Aortic/mitral stenosis: Use caution in patients with significant aortic/mitral stenosis.

• Renal artery stenosis: Use olmesartan with caution in patients with unstented unilateral/bilateral renal artery stenosis. When unstented bilateral renal artery stenosis is present, use is generally avoided due to the elevated risk of deterioration in renal function unless possible benefits outweigh risks.

• Renal impairment: Use with caution with pre-existing renal insufficiency.

Concurrent drug therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Special populations:

• Pediatric: Olmesartan has not been shown to be effective for hypertension in children younger than 6 years. Children younger than 1 year must not receive olmesartan for hypertension. The renin-angiotensin-aldosterone system plays a critical role in kidney development. Administering drugs that act directly on the renin-angiotensin-aldosterone system can have effects on the development of immature kidneys and alter normal renal development.

• Pregnancy: [US Boxed Warning]: Drugs that act on the renin-angiotensin system can cause injury and death to the developing fetus. Discontinue as soon as possible once pregnancy is detected.

• Surgical patients: In patients on chronic ARB therapy, intraoperative hypotension may occur with induction and maintenance of general anesthesia; however, discontinuation of therapy prior to surgery is controversial. If continued preoperatively, avoidance of hypotensive agents during surgery is prudent (Hillis, 2011).
