Drug-device combinations refer to medical products that combine a drug and a device in a single unit. These products are designed to deliver a drug to the body using a specific device or delivery system. Examples of drug-device combinations include inhalers, transdermal patches, and drug-eluting stents. These products are used to treat a variety of medical conditions, including respiratory diseases, cardiovascular diseases, and chronic pain. Drug-device combinations are regulated by the FDA and must meet specific safety and efficacy standards before they can be marketed to the public.
