US health regulators are watching for potential drug shortages after India restricted the export of some raw pharmaceutical ingredients, a move that could disrupt the industry’s globe-spanning supply chain.
India on Tuesday said that it would limit exports of some common medicines as concerns grow over shortages of chemical ingredients.
Many manufacturers of those ingredients in China are shut or making less medicine than usual due to the COVID-19 outbreak.

The drugs include over-the-counter painkiller and fever reducer paracetamol and finished pills that include it.
Similar restrictions have been placed on the common antibiotic metronidazole, various versions of vitamin B and eight other medicinal chemicals, a notice from the Indian government said.
“India has restricted the export of 26 active pharmaceutical ingredients for export, which represents about 10 percent of their export capacity,” US Food and Drug Administration (FDA) Commissioner Stephen Hahn told the US Congress at a hearing in Washington on Tuesday.
“We’re working very closely to look at that list to determine how that will affect the medical supply chain,” Hahn said.
So far, the FDA has only identified one drug that has gone into short supply because of coronavirus-related supply chain issues, although it has contacted 180 manufacturers.
Hahn declined to identify the drug, and said that alternatives are available.
Although India is the source of about 20 percent of the world’s generic-drug supply, the country relies on China for about 66 percent of the chemical components needed to make them.
A recent analysis by the Indian government found that as many as 450 drug ingredients could be affected by China’s virus containment efforts, which include a complete lockdown of Hubei Province, a center of the country’s drug industry.
The FDA has long grappled with drug shortages as drugmakers consolidated, shifted production overseas, and curtailed sales of unprofitable medicines.
Global health experts have encouraged US drugmakers to diversify their sources of pharmaceutical materials to avoid overdependence on any given country.
However, even diversification might not be a safeguard, said Yanzhong Huang (黃嚴忠), a senior fellow for global health at the New York-based Council on Foreign Relations.
“Manufacturing pharmaceuticals nowadays is so globalized and this is a worldwide pandemic,” Huang said. “This is the first time we’re facing a convergence of factors like this.”
Republican US lawmakers on Friday criticized US President Joe Biden’s administration after sanctioned Chinese telecoms equipment giant Huawei unveiled a laptop this week powered by an Intel artificial intelligence (AI) chip. The US placed Huawei on a trade restriction list in 2019 for contravening Iran sanctions, part of a broader effort to hobble Beijing’s technological advances. Placement on the list means the company’s suppliers have to seek a special, difficult-to-obtain license before shipping to it. One such license, issued by then-US president Donald Trump’s administration, has allowed Intel to ship central processors to Huawei for use in laptops since 2020. China hardliners
A top Vietnamese property tycoon was on Thursday sentenced to death in one of the biggest corruption cases in history, with an estimated US$27 billion in damages. A panel of three hand-picked jurors and two judges rejected all defense arguments by Truong My Lan, chair of major developer Van Thinh Phat, who was found guilty of swindling cash from Saigon Commercial Bank (SCB) over a decade. “The defendant’s actions ... eroded people’s trust in the leadership of the [Communist] Party and state,” read the verdict at the trial in Ho Chi Minh City. After the five-week trial, 85 others were also sentenced on
Conjoined twins Lori and George Schappell, who pursued separate careers, interests and relationships during lives that defied medical expectations, died this month in Pennsylvania, funeral home officials said. They were 62. The twins, listed by Guinness World Records as the oldest living conjoined twins, died on April 7 at the Hospital of the University of Pennsylvania, obituaries posted by Leibensperger Funeral Homes of Hamburg said. The cause of death was not detailed. “When we were born, the doctors didn’t think we’d make 30, but we proved them wrong,” Lori said in an interview when they turned 50, the Philadelphia Inquirer reported.

RAMPAGE: A Palestinian man was left dead after dozens of Israeli settlers searching for a missing 14-year-old boy stormed a village in the Israeli-occupied West Bank US President Joe Biden on Friday said he expected Iran to attack Israel “sooner, rather than later” and warned Tehran not to proceed. Asked by reporters about his message to Iran, Biden simply said: “Don’t,” underscoring Washington’s commitment to defend Israel. “We are devoted to the defense of Israel. We will support Israel. We will help defend Israel and Iran will not succeed,” he said. Biden said he would not divulge secure information, but said his expectation was that an attack could come “sooner, rather than later.” Israel braced on Friday for an attack by Iran or its proxies as warnings grew of
