The book "Drug Utilization Review on Corticosteroids Use" provides a comprehensive analysis of the application of corticosteroids through the method of Drug Utilization Review (DUR). It begins with an introduction to DUR and explains the selection of corticosteroids from a variety of drug classes. The work addresses the fundamental mechanisms of corticosteroid therapy, various administration techniques, as well as the relevant guidelines. Additionally, specific applications such as intra-articular and intranasal use of corticosteroids are discussed. Another focus is on adverse drug reactions, side effects, and antagonists. The study also analyzes therapeutic appropriateness, duplication, over- and under-utilization, drug interactions, as well as clinical misuse or abuse. Drug interactions are categorized by severity to clarify the impact of the medications on therapy.
