FDA-approved drugs are medications that have been evaluated and authorized by the U.S. Food and Drug Administration for safety and effectiveness. This approval process involves rigorous testing in clinical trials to ensure that the drug works as intended and does not pose significant risks to patients. Once a drug is approved, it can be prescribed by healthcare professionals and made available to the public. The FDA continues to monitor these drugs for any long-term effects or new safety concerns, ensuring that they remain safe for use after they enter the market.
