Misar (Telmisartan) is an angiotensin II receptor blocker (ARB). It is one of the commonly used antihypertensive medicines marketed by Highnoon Pharma.

It is a potent and sustained inhibitor of angiotensin II, an enzyme that causes blood vessels to constrict and raises blood pressure.

Misar is commonly used to treat hypertension, however, it has also been shown to be effective in reducing the risk of cardiovascular events in patients with high blood pressure.

Effectiveness of Misar (Telmisartan):

Misar has been shown to be very effective in lowering blood pressure in hypertensive patients.

In a study comparing Telmisartan 40 and 80 mg to Losartan 50 and 100 mg, it was found that Telmisartan was more effective in reducing systolic blood pressure as well as diastolic blood pressure, especially during the last six hours of a 24-hours period [Ref].

Comparison of Telmisartan Vs Losartan and Valsartan:

Losartan and valsartan are strong competitor medicines of Telmisartan. All three drugs are commonly used to treat hypertension and are very effective in lowering blood pressure.

While all three medications are effective in reducing blood pressure, Misar (Telmisartan) has some advantages over Losartan and Valsartan.

Misar has a longer half-life, which means that it stays in the body longer and can be taken once a day. It is true long-acting ARB that lowers blood pressure over 24 hours. 

Although Losartan and Valsartan can also be given once daily, their efficacy reduces at the end of the 24-hour period. It was shown in a study that Telmisartan lowered systolic blood pressure better in the last six hours of the 24-hour period.

Misar (Telmisartan) has also been shown to be effective and is considered the first-line ARB in various medical conditions. Here is the list of indications of various ARBs:

It is evident from the table above that Telmisartan is the first-line ARB in the treatment of Diabetes, Atrial fibrillation, Cardiovascular prevention, and metabolic syndrome [Ref].

Note: Candesartan should be avoided in patients with high uric acid while Olmesartan should be avoided in patients with Diabetes and Diabetic Nephropathy.

Comparison to Beta Blockers:

Beta-blockers are not the usual first-line of antihypertensive medicines. They work by blocking the effects of adrenaline, which can raise blood pressure. 

Beta-blockers can cause side effects such as fatigue, depression, and sexual dysfunction. Misar, on the other hand, has been shown to have a lower incidence of side effects compared to beta blockers, especially erection problems in men and depression.

In one study, Telmisartan was compared with Metoprolol. The study evaluated the effects of these drugs on arterial stiffness. Telmisartan was found much superior to Metoprolol in reducing arterial stiffness [Ref]

Misar Vs Amlodipine:

Amlodipine and other calcium channel blockers are commonly used to lower blood pressure in hypertensive patients. They work by relaxing the blood vessels, which can reduce blood pressure.

Calcium channel blockers can cause side effects such as constipation, headache, and dizziness. Misar, on the other hand, is better tolerated with minimal side effects compared to calcium channel blockers.

In a study that evaluated Telmisartan Vs Amlodipine, it was noted that both drugs effectively lowered blood pressure, however, the mean reduction in systolic and diastolic blood pressure over a 24-hour period was greater in the Telmisartan group compared to Amlodipine. 

A greater reduction in blood pressure was noted during the last four hours of a 24-hour period [Ref].

Misar Vs Diuretics:

Diuretics lower blood pressure by reducing the amount of fluid in the body. Diuretics are commonly used in combination with amlodipine and in patients at risk of fluid overload such as those with heart failure.

It can cause side effects such as frequent urination, low potassium levels, and erectile dysfunction. Misar, on the other hand, has been shown to have a lower incidence of side effects compared to diuretics.

Diuretics are usually given in combination with other antihypertensive medications.

In one study, the authors found that both Telmisartan and Valsartan effectively lowered blood pressure, however, when given in combination with Hydrochlorothiazide, Telmisartan was superior to Valsartan in lowering blood pressure [Ref]

Pros and Cons of Misar (Highnoon's Telmisartan):

Role of Misar in Heart Failure:

Heart failure occurs when the heart is unable to pump blood efficiently throughout the body. Misar has been shown to improve symptoms and reduce the risk of hospitalization in patients with heart failure.

In one study, Misar was compared to a placebo in patients with heart failure and preserved ejection fraction (a measure of the heart's pumping ability).

Misar was found to improve exercise capacity and reduce the risk of hospitalization compared to a placebo. Additionally, Misar has been shown to improve left ventricular function (the main pumping chamber of the heart) in patients with heart failure.

Misar reduced the risk of cardiovascular outcomes (death, stroke, myocardial infarction, and hospitalization) by a relative 8% compared to placebo [Ref]

Role of Misar in Diabetic Nephropathy:

Diabetic nephropathy is a condition in which the kidneys are damaged due to diabetes. Misar has been shown to slow the progression of diabetic kidney disease.

In one study, Misar was found to slow the decline in kidney function and reduce the risk of end-stage renal disease (ESRD) compared to a placebo in patients with type 2 diabetes and early-stage diabetic nephropathy.

In addition to reducing albuminuria, it reduced the progression to glomerulosclerosis and fibrosis [Ref]

Conclusion:

Misar is an effective medication for treating hypertension. It has been shown to be more effective than losartan in reducing systolic blood pressure and has a longer half-life than losartan and valsartan, making it a more convenient medication to take.

Additionally, Misar has a lower incidence of side effects compared to beta-blockers, calcium channel blockers, and diuretics.

Misar has been shown to improve insulin sensitivity and reduce inflammation in patients with metabolic syndrome apart from its role as a potent blood pressure-lowering drug, treatment of heart failure, and diabetic nephropathy.

Additionally, Misar slows cognitive decline and may be one of the potential drugs for preventing Alzheimer's disease.
