Drug administration is the process of delivering a pharmaceutical compound into the body to achieve a desired therapeutic effect. This can be done through various routes, such as oral, intravenous, intramuscular, subcutaneous, and topical administration. The goal of drug administration is to ensure the drug reaches the target site in the body and is absorbed and distributed effectively to exert its pharmacological action. Researchers in this area study methods to optimize drug delivery, such as developing novel drug delivery systems, improving drug bioavailability, and reducing side effects. Additionally, they investigate factors that can influence drug absorption, distribution, metabolism, and excretion in the body. Drug administration research is vital for developing safe and effective therapies for various medical conditions.
