What is the route of administration for the majority of the listed medications?

The majority of the medications in interventional radiology are administered via the intravenous (IV) route, particularly through an IV push. This method allows for rapid delivery of medication directly into the bloodstream, ensuring immediate therapeutic effects. Given that interventional radiology often involves procedures that require prompt action, such as pain management, sedation, or contrast administration for imaging studies, IV administration is typically preferred.

In addition, many medications used in this field have specific pharmacokinetic profiles that necessitate fast onset of action achievable through intravenous administration. These may include analgesics, sedatives, and certain contrast agents, which are crucial for the efficacy and safety of radiologic interventions.

While other routes of administration, such as oral, subcutaneous, and inhalation, may be utilized in different contexts, they are less common for the types of medications given in interventional procedures, where speed and immediate effect are pivotal. Thus, the IV push route is the most suitable answer for the majority of medications used in this practice.
