It works by blocking the receptors in the body that normally bind to a substance called angiotensin II.<\/p>\n\n\n\n<p>Angiotensin II is a hormone that causes the blood vessels to narrow or constrict. When this hormone binds to its receptors, blood pressure rises, forcing the heart to work harder to pump blood throughout the body. <\/p>\n\n\n\n<p>By blocking these receptors, telmisartan prevents angiotensin II from constricting the vessels. This allows the blood vessels to relax and widen, facilitating smoother blood flow, lowering blood pressure, and making it easier for the heart to pump.<\/p>\n\n\n\n<div class=\"quick-facts-card\">\n  <table class=\"quick-facts-table\">\n    <colgroup>\n      <col\/>\n      <col\/>\n    <\/colgroup>\n\n    <thead>\n      <tr>\n        <th colspan=\"2\">Quick Facts<\/strong><\/td>\n      <\/tr>\n    <\/thead>\n\n    <tbody>\n    <tr>\n    <td><strong>Common Brands<\/strong><\/td>\n    <td>Micardis<\/td> \n  <\/tr>\n  <tr>\n    <td><strong>Drug Class<\/strong><\/td>\n    <td>Angiotensin II receptor blocker (ARB)<\/td>\n  <\/tr>\n  <tr>\n    <td><strong>Generic Status<\/strong><\/td>\n    <td>Generic version of Micardis<\/td>\n  <\/tr>\n  <tr>\n    <td><strong>Availability<\/strong><\/td>\n    <td>Prescription only<\/td>\n  <\/tr>\n    <\/tbody>\n  <\/table>\n<\/div>\n\n\n\n\n<h2 class=\"wp-block-heading\" id=\"dosing\">Dosing<\/h2>\n\n\n\n<p>Telmisartan is an oral tablet available in dosage strengths of 20 mg, 40 mg, and 80 mg.

The recommended dose depends on what you\u2019re taking telmisartan for.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>High blood pressure:<\/strong> The recommended starting dose is 40 mg once daily.
