The Senate just confirmed Dr. Scott Gottlieb as the commissioner of the Food and Drug Administration.

Gottlieb is a healthcare investor, a physician, and well known in the drug industry. He previously served as former deputy commissioner of the FDA during George W. Bush's presidency.

Trump has said that he wants to deregulate the drug industry, which the FDA regulates, and has called the drug-approval process "slow and burdensome."

"We're going to be cutting regulations at a level that nobody's ever seen before," Trump said in a meeting with drug company executives on January 31. He estimated up to 80% of regulations would be slashed.

Over the years and at his Senate hearing, Gottlieb has been vocal about his thoughts on the FDA. Here's what his nomination could mean for the future of the agency.

He says he wants to change up the approval process for "complex generics," devices like the EpiPen or inhalers that competitors have a hard time getting approved. "When it comes to evaluating copies of these complex drugs, the fact is FDA doesn't have very good tools and policies," Gottlieb wrote in a 2014 opinion piece.

Gottlieb told Stat News that two of his highest priorities would be to ensure the safety of blood supplies and come down on unsafe foods.

He's also been critical of the pace at which the FDA approves drugs, compared to other countries. In a 2010 opinion piece in The Wall Street Journal, Gottlieb accused the FDA of evading the law.

What the FDA does

The FDA is responsible for regulating food and drugs. It's also responsible for regulating medical devices, blood donations, veterinary products, cosmetics, and tobacco. Trump's comments have left the drug industry concerned about what deregulation could mean for the drug-approval process.

It was officially founded in 1906, when the Food and Drugs Act was signed into law, prohibiting misbranded food, drinks, and drugs from interstate commerce. This cracked down on misleading claims that treatments could "cure" patients.
