Amlodipine and Olmesartan (Oral)

Proven to lower high blood pressure (hypertension), Amlodipine and Olmesartan are a blend of medicines that when combined, work together to effectively lower your risk of heart attacks and strokes. Prescribed to patients who experience high blood pressure, Amlodipine and Olmesartan is a calcium blocker that will widen and relax blood vessels. In turn, this helps to reduce the workload for your heart and arteries, consequently improving their health.


Otherwise known by its brand name Azor, Amlodipine and Olmesartan is an oral medication taken in the form of a tablet. Used to treat hypertension, it can be either taken alone or alongside other medications, as recommended by your doctor. It is only available with your doctor's prescription.

An effective calcium channel blocker (CCB), Amlodipine will affect the travel of calcium into your heart and blood vessel cells. Due to this, amlodipine reduces your heart's workload by relaxing the blood vessels and increasing its supply of blood and oxygen.

Olmesartan is known as an angiotensin II receptor blocker (ARB). ARBs work by stopping the effects of a hormone called ­angiotensin II in your body which can cause blood vessels to tighten, in turn restricting movement of blood and oxygen to the heart. As a result of this, Olmesartan works to relax blood vessels which lowers blood pressure and expands the supply of blood and oxygen to the heart.

Long-term high blood pressure is damaging to the body, in time causing the heart and arteries to not function correctly. This is harmful to the blood vessels of the heart, kidneys and brain and can cause strokes, heart failure and kidney failure. For those with high blood pressure, it is important to lower this hypertension and reduce its life-threatening risks. According to recent studies by Azor, high blood pressure affects a large number of the population, affecting one out of every three adults over the age of 20.

Once you have been prescribed Amlodipine and Olmesartan, it is vital that you take this medication exactly as prescribed by your doctor. It is important to not alter your amounts or take the medication for any duration longer or shorter than advised. For the best results, it is essential that you inform your doctor of any changes in your circumstances or whether you encounter any other illnesses as this may impact your treatment.

The most common adverse reaction alerted to healthcare professionals is edema, which is the buildup of fluid in some tissues within the body.

It can be reduced by lessening your salt intake or by taking medication to alleviate excess bodily fluid. However, if you notice any chest pain, difficulty in breathing or a shortness of breath, make sure to alert your doctor immediately, as these can be signs of a pulmonary edema, which is very serious.

Other common and easily managed side effects include bloating of the face, arms, hands, lower legs or feet and weight gain. You may also notice a feeling of warmth, redness of the face, neck or arms and sometimes the upper chest.

Less common side effects have been found to include unusual tiredness or weakness, dizziness, hair loss and a mild skin rash or itchiness. These side effects are less serious but can be unpleasant. If you experience any of these side effects, discuss how they can be managed and maintained by your doctor.

Amlodipine and Olmesartan poses a serious threat to pregnancies, having been proven to cause fetal toxicity and injury to developing fetuses. It acts directly on the renin-angiotensin system (RAS), a hormone system that controls blood pressure and fluid balance and is known to cause injury and death to a developing fetus.
