Abstract
The route of drug administration plays a crucial role in determining the pharmacokinetics and pharmacodynamics of a drug. The choice of administration route affects the absorption, distribution, metabolism, and excretion of drugs, influencing their onset, intensity, and duration of action. This article reviews the pharmacological implications of different drug administration routes, including oral, intravenous, intramuscular, subcutaneous, and inhalation. We discuss the factors influencing route selection, the advantages and disadvantages of each route, and the impact of these routes on drug efficacy and safety.
