(WASHINGTON) -- President Donald Trump on Thursday unveiled his TrumpRx website in an event at the White House, listing 40 drugs at lower cost than previous list prices to patients paying out of pocket and calling the launch part of the "most transformative health care initiatives."

Trump made the announcement alongside Centers for Medicare and Medicaid Services Administrator Dr. Mehmet Oz and National Design Studio Director Joe Gebbia.

"Starting tonight, dozens of the most commonly used prescription drugs will be available at dramatic discounts for all consumers throughout a new website is called TrumpRx.gov," Trump said at the White House event.

Some of the reduced cash prices were announced last year by the administration and some of the new prices had already gone into effect.

The president touted the use of his Most Favored Nation (MFN) policies -- making sure the U.S. isn't paying more than other countries -- for making the lower prices possible.

"For years, politicians from both parties have promised to bring down prescription drug prices and make health care more affordable, but they all failed," Trump said.

According to the TrumpRx website, these drugs can be obtained at participating pharmacies using coupon card codes displayed on the website or directly through manufacturers' websites.

The website also notes that "TrumpRx discounted pricing is only available for cash-paying patients," in a FAQ section. The discounts are not available for patients trying to pay through insurance and do not go toward insurance deductibles.

Only a few dozen drugs are offered on the website, though the website says that "many more drugs are coming soon," in a FAQ section.

"It's nice that they are aggregating coupons in one place," Benjamin Jolley, PharmD, a senior fellow for health care at the American Economic Liberties Project told ABC News. "But it's a convenience to check the website to see the coupons all in one place for the first time.
