• Recent EU Clinical Trials: Feasibility of Aggressive Albuminuria Reduction in Biopsy-Proven Diabetic Nephropathy - A Pilot Study
• Recent NIPH Clinical Trials: Effect of telmisartan on patients with renal dysfunction
• Pharmacological Profile: Telmisartan is a selective angiotensin II type 1 receptor antagonist (ARB), also known as an angiotensin receptor blocker. It has a unique pharmacologic profile with partial agonistic activity on peroxisome proliferator-activated receptor 纬 (PPAR纬).; Unlike other ARBs, telmisartan has a long half-life of about 24 hours, resulting in sustained blood pressure reduction and prolonged action. It exhibits high lipophilicity, facilitating oral absorption, tissue distribution, and cell penetration, leading to a larger volume of distribution.
• Clinical Uses: Telmisartan is used primarily for the management of hypertension, either as monotherapy or in combination with other antihypertensive agents. Considered a first-line drug for mild-to-moderate hypertension with an excellent safety profile. It is also utilized in the treatment of hypertension-related cardiovascular end-organ damage.
• Clinical Uses: Telmisartan's dual activity as an ARB and partial PPAR纬 agonist provides multiple clinical benefits, including anti-diabetic and cardiovascular effects. Animal studies suggest that telmisartan is more effective in improving metabolic syndrome compared to other ARBs, with benefits in insulin resistance, lipid profile, and blood pressure control.
• Potential Use in Covid-19: Telmisartan, along with other ARBs, has been proposed as a potential treatment for COVID-19-induced lung inflammation due to its anti-inflammatory properties.
• Pharmacokinetics and Binding Affinity: Telmisartan has a very low binding affinity for angiotensin II type 2 receptors (AT2) and minimal binding to other receptors such as catecholamine, acetylcholine, dopamine, serotonin, and histamine. It is primarily eliminated through feces, distinguishing it from other ARBs that undergo renal excretion to varying extents.
