Telmisartan and HCTZ provide consistent blood pressure reduction throughout the day, reducing fluctuations that could increase cardiovascular risk. Telmisartan helps reduce the risk of heart attack, stroke, and other cardiovascular events by improving blood vessel health and reducing strain on the heart. Hydrochlorothiazide can cause potassium loss, but Telmisartan helps counterbalance this by promoting potassium retention, reducing the risk of hypokalemia (low potassium levels). Telmisartan has a neutral or positive effect on lipid profiles and glucose metabolism, making it suitable for patients with diabetes or metabolic syndrome. It is effective for Resistant Hypertension and Ideal for patients whose blood pressure is uncontrolled by monotherapy, as the dual action addresses multiple pathways to high blood pressure.
Telmisartan’s Unique Tissue Protective Effects have additional benefits beyond blood pressure control. It helps prevent kidney damage, especially in patients with diabetes or at risk of diabetic nephropathy. Its anti-inflammatory and Vascular Protective Effects reduce oxidative stress and improve endothelial function. Telmisartan’s extended half-life ensures sustained action, even after missing a dose. Telmisartan and Hydrochlorothiazide are well-studied, with established efficacy and safety over long-term use.
What is Telma H 40mg?
Telma H 40 mg combines two active ingredients, Telmisartan (40 mg) and Hydrochlorothiazide (12.5 mg). It effectively manages high blood pressure (hypertension). Each component works via a distinct mechanism, providing complementary benefits for blood pressure control and cardiovascular health.
Mechanism of Action
- Telmisartan (40 mg)
Type: Angiotensin II Receptor Blocker (ARB).
How It Works
Angiotensin II is a hormone that causes blood vessels to constrict, raising blood pressure. Telmisartan blocks angiotensin II from binding to its receptors in blood vessel walls. It leads to vasodilation (relaxation of blood vessels), lowering systemic vascular resistance, and reducing blood pressure. It helps kidneys excrete sodium and water, reducing fluid retention. It promotes potassium retention, countering potassium loss caused by Hydrochlorothiazide. It improves endothelial (blood vessel lining) function, reducing cardiovascular risks.
- Hydrochlorothiazide (12.5 mg)
Type: Thiazide Diuretic.
How It Works
Hydrochlorothiazide acts on the kidneys, specifically the distal convoluted tubules, to block sodium reabsorption. It increases the excretion of sodium, chloride, and water through urine. Reducing blood volume leads to a decrease in cardiac output, which lowers blood pressure. It reduces fluid retention (edema), further aiding blood pressure control. It mildly dilates blood vessels, enhancing the antihypertensive effect.
How the Combination Works Together
Dual Action for Blood Pressure Control
- Telmisartan reduces vascular resistance by relaxing blood vessels.
- Hydrochlorothiazide reduces blood volume and enhances sodium excretion.
- The combination addresses two key contributors to hypertension: increased fluid volume and vascular constriction.
Potassium-Sparing Effect of Telmisartan
Hydrochlorothiazide can cause potassium loss, which Telmisartan’s potassium-sparing properties counteract. It reduces the risk of hypokalemia (low potassium levels).
Sustained 24-Hour Control
Telmisartan’s long half-life (24+ hours) ensures steady blood pressure control throughout the day. Hydrochlorothiazide enhances the early antihypertensive effect by reducing fluid overload.
Cardiovascular Protection
Telmisartan offers additional protective effects, such as reducing oxidative stress and improving heart and kidney function. It is beneficial for patients with diabetes or kidney disease.
Overall Effects of Telma H 40 mg
Reduces Blood Pressure: By relaxing blood vessels and lowering blood volume.
Protects Organs: Reduces strain on the heart, kidneys, and blood vessels, preventing long-term damage.
