The process of how medicine enters and gets distributed throughout the human body is a complex and fascinating one. From the moment a medication is ingested, applied, or injected, it undergoes a series of transformations that determine how much of the medication reaches its intended target and how much gets metabolized or excreted. The route of administration, the chemical properties of the medication, and the physiology of the individual are just some of the factors that can influence how quickly and effectively a medication is absorbed into the bloodstream and transported to its site of action. Understanding the mechanisms of drug absorption is crucial for ensuring that medications are used safely and effectively.
