Telmisartan and Hydrochlorothiazide Tablet, Uses, Dosage, Benefits

Dec 04, 2025

TELMISTRUM 80 H is a fixed-dose combination medicine containing Telmisartan 80 mg and Hydrochlorothiazide (HCTZ). It is widely prescribed in India for the effective management of high blood pressure (hypertension). Uncontrolled hypertension is one of the leading causes of heart attacks, stroke, kidney disease, and other cardiovascular complications. TELMISTRUM 80 H offers dual therapeutic action—Telmisartan reduces vascular resistance by blocking angiotensin II receptors, while Hydrochlorothiazide acts as a diuretic to help the body eliminate excess sodium and water. This combined effect helps achieve consistent blood pressure control in patients who do not respond well to single-drug therapy.

Telmisartan belongs to the class of Angiotensin II Receptor Blockers (ARBs), known for their strong antihypertensive effect with minimal side effects. Hydrochlorothiazide, a thiazide diuretic, enhances the impact of Telmisartan by reducing fluid overload and relaxing blood vessels. Together, they offer a more reliable and sustained blood pressure-lowering effect.

In India, combination therapies are increasingly recommended for patients whose blood pressure remains above the target range despite lifestyle modifications and monotherapy. TELMISTRUM 80 H helps meet these therapeutic goals while reducing complications associated with long-term hypertension.

This detailed article covers everything a patient or healthcare professional needs to know about TELMISTRUM 80 H—its uses, benefits, dosage guidelines, potential side effects, precautions, and a summary conclusion for improved understanding and informed medical decisions.

Telmisartan And Hydrochlorothiazide Tablet Uses

TELMISTRUM 80 H is prescribed primarily for managing moderate to severe hypertension. It serves multiple therapeutic needs, especially for patients who require stronger or combination treatment. Its uses include:

1. Treatment of Primary Hypertension

For individuals diagnosed with high blood pressure without any other secondary cause, this combination tablet helps bring down systolic and diastolic blood pressure effectively.

2. Management of Resistant Hypertension

Some patients do not respond adequately to a single antihypertensive drug. TELMISTRUM 80 H provides dual-mechanism control ideal for such cases.

3. Reduction of Cardiovascular Complications

By maintaining blood pressure within normal ranges, the medicine reduces risks of:

  • Heart attack

  • Stroke

  • Heart failure

  • Atherosclerosis

4. Management of Hypertension in Diabetic Patients

High blood pressure is especially dangerous for individuals with diabetes. Telmisartan protects kidneys while Hydrochlorothiazide supports fluid balance.

5. Mild to Moderate Edema Associated with Hypertension

The diuretic action of Hydrochlorothiazide helps reduce fluid retention in patients who also suffer from swelling.

6. Prevention of Left Ventricular Hypertrophy

Long-standing hypertension can cause the heart muscles to thicken. Keeping BP controlled reduces this risk.

7. Kidney Protection in Hypertensive Patients

Telmisartan and  supports kidney function by improving blood flow to renal tissues, reducing microalbuminuria.

8. Patients with High Cardiovascular Risk

Individuals with risk factors such as age, obesity, cholesterol, or smoking benefit from tighter blood pressure management.

9. Supportive Therapy in Metabolic Syndrome

TELMISTRUM 80 H is often part of the treatment plan in patients who suffer from metabolic syndrome components such as high BP, insulin resistance, and abdominal obesity.

Benefits of Telmisartan and Hydrochlorothiazide Tablet

This combination therapy provides comprehensive, long-term benefits for hypertensive patients. TELMISTRUM 80 H is considered more effective than either medicine alone.

1. Powerful Dual Mechanism for BP Control

Telmisartan blocks vasoconstricting effects of angiotensin II, while Hydrochlorothiazide reduces sodium retention. Together, they significantly lower BP.

2. Long-Lasting 24-Hour Effect

One daily dose offers consistent round-the-clock control, reducing fluctuations in blood pressure.

3. Reduced Risk of Stroke and Heart Disease

Maintaining stable blood pressure lowers the chances of heart attacks, arrhythmias, and strokes.

4. Kidney Protection

Telmisartan and hydrochlorothiazide  provides renal protection, especially helpful for diabetic patients or those with early kidney disease.

5. Less Swelling and Fluid Retention

Hydrochlorothiazide helps remove excess water, reducing bloating, ankle swelling, and breathlessness.

6. Improved Arterial Health

Chronic hypertension damages arteries. This medicine keeps arteries flexible and reduces stiffness.

7. Better BP Control Than Monotherapy

Patients who do not respond adequately to one antihypertensive often achieve optimal results with this combination.

8. Lower Incidence of Cough Compared to ACE Inhibitors

Unlike ACE inhibitors, ARBs like Telmisartan rarely cause persistent dry cough.

9. Helps Improve Lifestyle Quality

Patients experience better energy levels, reduced fatigue, fewer headaches, and improved cardiovascular function.

10. Weight-Neutral and Metabolically Friendly

This combination generally does not interfere with glucose metabolism, making it safe for diabetic patients.

Dosage of Telmisartan And Hydrochlorothiazide Tablet 

Dosage should be determined strictly by a healthcare professional. TELMISTRUM 80 H is usually prescribed once daily for continuous blood pressure management.

1. Standard Adult Dosage

  • One tablet daily, usually in the morning.

  • Can be taken with or without food.

  • Swallow the tablet whole with water.

2. Dose Adjustment

Doctors may adjust the dose based on:

  • Severity of hypertension

  • Coexisting conditions (diabetes, kidney issues, etc.)

  • Response to treatment

3. Consistency Is Key
