Drug therapy is a medical treatment that uses medications to manage or cure diseases and health conditions. It can involve various types of drugs, including antibiotics for infections, antidepressants for mental health issues, and pain relievers for discomfort. The goal is to improve a patient's quality of life by alleviating symptoms or addressing the underlying causes of their condition. Healthcare professionals, such as doctors and pharmacists, play a crucial role in prescribing and managing drug therapy. They consider factors like a patient's medical history, age, and other medications to ensure safe and effective treatment. Regular monitoring is often necessary to assess the therapy's effectiveness and make adjustments as needed.
