US drugmaker Viatris was yesterday ordered to recall two batches of Norvasc, a high blood pressure drug, as the Food and Drug Administration (FDA) said iron wires were found in samples taken from the shipment.
The recall applies to 6 million Norvasc 5mg tablets from batches FR3135 and FT2343, the agency said, adding that it ordered the company to complete the recall by Jan. 29.
The active agent in Norvasc is amlodipine besylate, which inhibits the movement of calcium ions across cardiac muscles and the lining of blood vessels.

The recall order came after the Consumers’ Foundation last month held a news conference to detail complaints from local long-term users of Norvasc.
FDA Medicinal Products Division head Hung Kuo-teng (洪國登) cited users of the drug as telling the event that they had found wires in the tablets when breaking them in half.
The FDA has launched an investigation and asked Viatris to provide information about the drug, Hung said.
This led to the identification of the FR3135 batch, he said, adding that the FDA suspected that the other batch might also be affected and recalled it as well.
Hung said that with about 210 million tablets sold last year, Norvasc accounted for about 60 percent of its segment in the local high blood pressure drug market.
The FDA also ordered Viatris to submit a report on the incident and detail measures it would take to ensure that the issue does not occur again, Hung said.
Norvasc users who are affected by the recall and want to change to an alternative medication should consult a doctor before doing so, the FDA said.
AGING: While Japan has 22 submarines, Taiwan only operates four, two of which were commissioned by the US in 1945 and 1946, and transferred to Taiwan in 1973 Taiwan would need at least 12 submarines to reach modern fleet capabilities, CSBC Corp, Taiwan chairman Chen Cheng-hung (陳政宏) said in an interview broadcast on Friday, citing a US assessment. CSBC is testing the nation’s first indigenous defense submarine, the Hai Kun (海鯤, Narwhal), which is scheduled to be delivered to the navy next month or in July. The Hai Kun has completed torpedo-firing tests and is scheduled to undergo overnight sea trials, Chen said on an SET TV military affairs program. Taiwan would require at least 12 submarines to establish a modern submarine force after assessing the nation’s operational environment and defense
A white king snake that frightened passengers and caused a stir on a Taipei MRT train on Friday evening has been claimed by its owner, who would be fined, Taipei Rapid Transit Corp (TRTC) said yesterday. A person on Threads posted that he thought he was lucky to find an empty row of seats on Friday after boarding a train on the Bannan (Blue) Line, only to spot a white snake with black stripes after sitting down. Startled, he jumped up, he wrote, describing the encounter as “terrifying.” “Taipei’s rat control plan: Release snakes on the metro,” one person wrote in reply, referring
The coast guard today said that it had disrupted "illegal" operations by a Chinese research ship in waters close to the nation and driven it away, part of what Taipei sees a provocative pattern of China's stepped up maritime activities. The coast guard said that it on Thursday last week detected the Chinese ship Tongji (同濟號), which was commissioned only last year, 29 nautical miles (54km) southeast of the southern tip of Taiwan, although just outside restricted waters. The ship was observed lowering ropes into the water, suspected to be the deployment of scientific instruments for "illegal" survey operations, and the coast
