Therapeutic agents refer to medications or substances that are used to treat a medical condition, disease or disorder. These agents can be in various forms such as drugs, vitamins, supplements, hormones and other natural or synthetic compounds that have the ability to cure or alleviate symptoms of an illness when administered properly. They work by interacting with specific biological targets like enzymes, receptors or organs to produce a desired therapeutic effect in patients. The use of these agents is based on scientific evidence and their efficacy has been proven through clinical trials before they are approved for public consumption.
