Drug mechanisms refer to the specific ways in which medications interact with the body to produce their effects. Each drug works by targeting certain molecules, such as proteins or enzymes, to either enhance or inhibit their activity. For example, pain relievers like ibuprofen block enzymes that cause inflammation, helping to reduce pain and swelling. Understanding drug mechanisms is crucial for developing new treatments and improving existing ones. By knowing how a drug works, researchers can design better medications with fewer side effects. This knowledge also helps doctors prescribe the right drugs for specific conditions, ensuring patients receive the most effective care possible.
