New Delhi: The U.S. Food and Drug Administration said on Tuesday certain samples of sitagliptin, a compound in Merck's diabetes drugs Januvia and Janumet, were contaminated with a possible carcinogen.
The agency said it would temporarily allow Merck to distribute drugs with sitagliptin containing a higher than normally acceptable amount of the impurity Nitroso-STG-19, also known as NTTP, in order to avoid a shortage.
Merck said it notified authorities it had detected that some batches of the drugs contained the impurities and implemented additional quality controls to make sure its drugs will meet the interim acceptable limits.
"We remain confident in the safety, efficacy and quality of our sitagliptin-containing medicines," Merck said, noting that no significant impact on supply is expected.
Shares of Merck, which was not immediately available for comment, fell sharply before recovering to close up over 1% at $89.53.
