Valsartan API
CAS Number: 137862-53-4
Valsartan API
Mechanism of Action
Valsartan blocks the actions of angiotensin II, which include constricting blood vessels and activating aldosterone, to reduce blood pressure.[7]The drug binds to angiotensin type I receptors (AT1), working as an antagonist. This mechanism of action is different than that of the ACE inhibitor drugs, which block the conversion of angiotensin I to angiotensin II. As valsartan acts at the receptor, it can provide more complete angiotensin II antagonism since angiotensin II is generated by other enzymes as well as ACE. Also, valsartan does not affect the metabolism of bradykinin like ACE inhibitors do
Indication
Diovan 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
- Treatment of heart failure (NYHA class II-IV); Diovan significantly reduced hospitalization for heart failure
- Reduction of cardiovascular mortality in clinically stable patients with left ventricular failure or left ventricular dysfunction following myocardial infarction

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.
Please contact our team of experts at api@drreddys.com for any queries. You can also find further information on our sartan API approach in the whitepaper here

Dr. Reddy’s is featured in an article of Global Pharma Insights on “Nitrosamine contamination: pharma’s re-evaluation of its supply chain”
Dr. Reddy’s was one of the very first API manufacturers to instigate a complete review to ensure that nitrosamine impurities are avoided by design and analytical methods are in place which meet the future stringent limits which have been set by regulatory agencies.
On winning the API Supplier of the Year award at the Generics Bulletin’s Annual Global Generics & Biosimilars Awards 2019, Dr. Reddy’s was also commended on the proactive and methodical approach followed to address the nitrosamine impurities situation with Sartan APIs (such as Valsartan).
