Mechanism of Action
Angiotensin II is formed from angiotensin I in a reaction catalyzed by angiotensin-converting enzyme (ACE, kininase II). Angiotensin II is the principal pressor agent of the renin-angiotensin system, with effects that include vasoconstriction, stimulation of synthesis and release of aldosterone, cardiac stimulation, and renal reabsorption of sodium. Telmisartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT1 receptor in many tissues, such as vascular smooth muscle and the adrenal gland. Its action is therefore independent of the pathways for angiotensin II synthesis.
There is also an AT2receptor found in many tissues,but AT2isnot knownto beassociated withcardiovascular homeostasis. Telmisartan has muchgreater affinity (>3,000 fold) for the AT1 receptor than for the AT2 receptor.
Blockade of the renin-angiotensin system with ACE inhibitors, which inhibit the biosynthesis of angiotensin II from angiotensin I, is widely used in the treatment of hypertension. ACE inhibitors also inhibit the degradation of bradykinin, a reaction also catalyzed by ACE. Because telmisartan does not inhibit ACE (kininase II), it does not affect the response to bradykinin. Whether this difference has clinical relevance is not yet known. Telmisartan does not bind to or block other hormone receptors or ion channels known to be important in cardiovascular regulation.
Blockade of the angiotensin II receptor inhibits the negative regulatory feedback of angiotensin II on renin secretion, but the resulting increased plasma renin activity and angiotensin II circulating levels do not overcome the effect of telmisartan on blood pressure.
Indication
MICARDIS is an angiotensin II receptor blocker (ARB) indicated for:
- Treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions.
- Cardiovascular (CV) risk reduction in patients unable to take ACE inhibitors

EMA Nitrosamine Guidance – Deadline March 31, 2021
MAHs should ensure that they and the manufacturing authorization holder have access to all relevant information from the API manufacturers about the potential formation of nitrosamine impurities and the potential for cross-contamination.
The call for review consists of the following three steps:
- Step 1: MAHs to perform a risk evaluation to identify if APIs and/or FPs could be at risk of the presence of N-nitrosamine under the principles outlined in Q&A 7 of the Q&A for the implementation article 5(3):
- Step 2: If a risk is identified, MAHs to proceed with confirmatory testing to confirm or refute the presence of N-nitrosamines, accordance with the principles outlined in Q&As 8 and 9 of the Q&A for the implementation of Article 5(3). MAHs should report the outcomes as soon as possible.
- Step 3: If the presence of N-nitrosamine(s) is confirmed, MAHs should implement effective risk-mitigating measures through the submission of variations:
− to be undertaken before September 26, 2022, for human medicines containing chemically synthesized APIs;
− to be conducted before July 1 2023, for human medicines containing biological active substances.
MAHs are required to respond to the RAs on the outcome of step 1 and step 2 by utilizing agreed published templates provided on the EMA/ CMDh websites.
How we can help
Our regulatory and scientific experts at Dr. Reddy’s were amongst the forerunners in addressing the issue right from the beginning. We provide our customers with a full assessment for all our sartan APIs, which confirm the absence of NDMAs and analytical testing that already comply with the new acceptance limits. In addition to sartan APIs, we’ve performed a complete Step-1 nitrosamine assessment for around 270 chemically synthesized APIs.
