Drugs are substances that can alter physiological processes in the body. They can be used therapeutically to treat diseases, relieve symptoms, or prevent health issues. Drugs interact with the body's systems by binding to specific receptors or enzymes, influencing the function of cells and tissues. While beneficial in many cases, drugs can also have side effects and lead to dependency or tolerance if misused. The study of how drugs work, known as pharmacology, is essential for developing new medications and understanding their impact on biological systems .
