Olmesartan

Olmesartan

Olmesartan belongs to a family of drugs called angiotensin II receptor blockers (ARBs). This medicine helps relax blood vessels by blocking angiotensin II, a natural substance that tightens blood vessels.

Untreated high blood pressure can seriously damage your brain, heart, blood vessels and kidneys. Olmesartan helps by blocking substances that constrict blood vessels, which allows them to relax and reduces pressure. Research shows this medication does more than control hypertension - it can lower the risk of cardiovascular events and death rates in patients with ischemic heart disease. This article explains what olmesartan is, its mechanisms, dosing and safety measures.

What is Olmesartan?

This effective medicine comes from a family of drugs called angiotensin II receptor blockers (ARBs). It blocks angiotensin II from binding to its receptors, which are mostly found in blood vessels. This action reduces vasoconstriction, lowers aldosterone levels, and helps your body remove more sodium—all these effects help lower blood pressure.

Olmesartan Tablet Uses

Doctors prescribe olmesartan to treat high blood pressure in adults and children who are at least 6 years old. You might take it alone or with other blood pressure medications to get better results. It helps manage Type 2 diabetes-associated nephropathy, heart failure and post-myocardial infarction, especially if you can't tolerate ACE inhibitors.

How and When to Use Olmesartan Tablet

You should take olmesartan at the same time each day, with or without food. Taking it with food might help if you experience stomach upset. Pharmacists can prepare a liquid form for children who have trouble swallowing tablets.

Side Effects of Olmesartan Tablet

Common side effects include:

• Dizziness 
• Headaches 
• Upper respiratory infections 
• Back pain

Serious side effects include: 

• Face or throat swelling
• Severe diarrhoea with weight loss
• Reduced urination
• High potassium levels that can cause nausea, weakness, chest pain, or irregular heartbeats.

Precautions

• Never use olmesartan during pregnancy, as it can harm unborn babies, especially during the second and third trimesters. 
• Diabetic patients should not mix olmesartan with medicines containing aliskiren. 
• People with kidney disease need regular monitoring since the medicine can affect kidney function.
• Your blood pressure might drop too low if you get dehydrated from illness, sweating, or not drinking enough fluids while taking olmesartan. 

How Olmesartan Tablet Works

Your body's angiotensin II receptors face selective blocking from Olmesartan. Blood vessels normally tighten when angiotensin II attaches to these receptors. Olmesartan relaxes and widens blood vessels by stopping this attachment.

The medicine's binding strength to angiotensin type I receptors is significant as it is 12,000 times stronger than to type II receptors. This targeted blocking reduces aldosterone release from your adrenal gland, which decreases sodium reabsorption in your kidneys. Your body then eliminates extra sodium and water, which helps lower blood pressure through multiple pathways.

A single daily tablet of olmesartan keeps your blood pressure in check all day, unlike other medicines that need frequent doses.

Can I Take Olmesartan with Other Medicines?

You need to consider before combining these medicines with olmesartan:

• ACE Inhibitors
• Aliskiren 
• Colesevelam
• Diuretics
• Lithium 
• Over-the-counter NSAIDs (ibuprofen, naproxen)
• Potassium supplements
• Trimethoprim

Dosage Information

Adults typically start with 20 mg once daily. Your doctor might increase the dose to Olmesartan 40 mg daily after two weeks if needed. 

A child's dosage depends on weight:

• Ages 6-16 weighing 35kg or more: Olmesartan 20 mg once daily, with possible increase to 40 mg
• Ages 6-16 weighing 20-35kg: 10 mg once daily, with possible increase to 20 mg

Patients with creatinine clearance below 20 mL/min should not take more than 20 mg daily. Careful monitoring is essential for patients with heart failure, hypotension or liver disease.

Olmesartan remains a simple once-daily medication that effectively controls blood pressure, despite these possible adjustments.

Conclusion

Olmesartan helps people who struggle with high blood pressure. The medicine blocks harmful substances that constrict blood vessels, and this allows them to relax and widen. Doctors prescribe it mainly for hypertension, but it also reduces cardiovascular events and helps diabetes patients with kidney issues. Most patients find the once-daily dosing convenient. Olmesartan is a vital tool that maintains long-term health when used properly under medical supervision. Talk to your doctor before making changes to your treatment plan.
