High Blood Pressureand Losartan Potassium

Losartan can alleviate blood pressure issues by relaxing the blood vessels of the patient. It does so by blocking the effects of a certain chemical in our body, known as angiotensin II. This chemical tends to narrow and tighten blood vessels in our body at several sites including vascular smooth muscle and adrenal glands. Since Losartan widens the vessels, blood pressure gets lowered; thus, the patient gets treated.

In addition, Losartan Potassiumalso enhances patient’s urinary flow. Excretion of certain substances i.e. phosphate, calcium, magnesium etc. from the body of thepatient is improved with this drug.

A study has been conducted to examine the use of Losartan potassium to treat breast cancer tumors. Results showed that the drug is successful in blocking reverse neoplastic changes caused by angiotensin II receptor antagonist.

Atenolol is a prescription drug employed in treating high blood pressure and other coronary diseases.  Atenolol was approved by the FDA in August 1981.  Atenolol is sold under the brand name Tenormin.  It belongs to a class of medication referred to as beta blockers.  These beta blockers are drugs which help to control cardiovascular diseases by reducing the rate at which the heart works.  Hence, the workload on the heart is reduced, and thus the blood pressure is lowered. Apart from treating high blood pressure, Atenolol is also used to treat chest pain and angina.  Over time, it has been observed that Atenolol improves the survival rates after a heart attack due to its ability to reduce the severity of the heart attack.  Atenolol is present in the market today in many generic forms from different companies.  Other medical conditions Atenolol treats include rhythm disorders, alcohol withdrawal, Graves’ disease and migraines.  For Atenolol to be effective, a patient must use it regularly.  Also, Atenolol is not suitable for pregnant women; it may harm an unborn child. Its side effects are usually mild, and they include abdominal cramps, constipation, impotence, fever, depression, lightheadedness, numbness and cold extremities.  Atenolol is also capable of causing breathing difficulties in asthmatic patients or people with emphysema and chronic bronchitis.

Losartan Potassium Side Effects

Like other hypertension-treatment drugs, Losartan potassium side effects are real as well.  Some side effects of Losartan potassium may occur that usually do not need medical attention. These side effects may stop manifesting as your body adjusts to the medicine and the treatment.  However, some side effects are persistent, and the only way to be safe is by stopping the medication.  Severe side effects of Losartan potassium involves difficulty in breathing, swelling of the face, lips, tongue or throats, the breakdown of skeletal muscle tissue leading to kidney failure.  Less severe or mild side effects include a dry cough, muscle cramps, cold or flu symptoms, stomach pain, sleep problems, diarrhea, and tiredness.  Others are burning sensation during urination, pale skin, wheezing, chest pain, drowsiness, confusion, mood changes, or high potassium (slow heart rate, weak pulse, muscle weakness, tingly feeling).

Losartan Potassium 50 mg Side Effects

Cozaar 50 mg tablets or Losartan Potassium 50 mg tablets (losartan potassium) refers to a tablet containing 50 mg concentration of Losartan potassium.  Adult patients with High Blood Pressure Treatment usually starts with 50 mg Losartan potassium. Its side effects are less pronounced than more concentrated Losartan potassium tablets of 100 mg and 250 mg.  A severe side effect is a severe allergic reaction (rash, itching, swelling of the face, lips, mouth or throat that may cause difficulty in swallowing or breathing).  Common side effects are dizziness, low blood pressure, disability, fatigue, hypo and hyperkalemia, and anemia.  Uncommon side effects include a headache, sleep disorders, lethargy, severe chest pain (angina pectoris), dyspnea, and abdominal pain.  Rare side effects include hypersensitivity, fainting, depression, disturbed taste and inflammation of blood vessels.


Diovan is a trade name for Valsartan, which is a drug mainly used for the treatment of congestive heart failure, treatment of high blood pressure and to improve the chances of a heart-attack patient staying alive for long. Diovan is also used to reduce death for people with left ventricular dysfunction after surviving a heart attack. It is an angiotensin receptor blocker (ARB) that selectively blocks the type I angiotensin receptor.  Blocking the actions of angiotensin II includes constricting blood vessels and activating aldosterone, which in turn reduces blood pressure.  Diovan (Valsartan) is in FDA pregnancy category D and includes a black box warning for fetal toxicity.  Diovan’s side effects are dependent on whether it is being used for treating hypertension or heart failure.  For heart failure, common side effects include dizziness, low blood pressure, and diarrhea, while less common side effects include back and joint pains.  For the treatment of hypertension, patients may experience side effects like diarrhea, headache, cough, upper respiratory infection, dizziness, and others.

Losartan Potassium HCTZ

Losartan potassium HCTZ refers to a combination of Losartan potassium-hydrochlorothiazide.  It is sold under the trade name – Hyzaar and is available in many generic forms.  This combination is one of an angiotensin II receptor antagonist and a thiazide diuretic (water pill) and is used in treating hypertension.  Losartan potassium HCTZ is also used to lower the risk of stroke in individual patients with an existing heart condition.  Hyzaar is also used to reduce the risk of stroke in certain people with heart disease. Hyzaar is available in generic form.

Common side effects of Losartan potassium HCTZ include back pain, tired feeling, skin rash, sore throat/dry cough, stomach pain and others.  Losartan potassium may interfere with other blood pressure drugs, lithium, steroids, oral diabetes medications, other diuretics, muscle relaxers or narcotics.  In rare cases, Losartan potassium HCTZ can cause a condition that leads to the breakdown of skeletal muscle tissue, leading to kidney failure.  It is not recommended to be taken by pregnant women as it may harm the fetus.

Valsartan vs. Losartan

Both Losartan (Cozaar) and Valsartan (Diovan) are excellent medications used in protecting kidney function, as an ACE inhibitor.  However, they both have fewer side effects.  Both drugs are not safe for pregnant women.  They are both first-choice blood pressure treatments for many people, and they lower the risk of heart attack and stroke.  They are both available in the pill forms.  Though losartan and valsartan are similarly effective in reducing blood pressure in patients with mild to moderate hypertension, Losartan, not valsartan was associated with a decrease in serum uric acid levels.  Valsartan has been said to be the more effective of the two. However, doctors always prescribe Losartan first to their patients, and when it does not make any difference to the patient’s blood pressure, they prescribe Diovan next.
