Abstract:
Introduction: Psychomotor agitation represents a complex medical emergency, particularly challenging in prehospital settings. Since March 2020, the incidence of psychomotor agitation has significantly increased. Rationale: Emergency Medical Services (EMS) frequently serve as the first point of contact, bearing the critical responsibility of effectively managing these situations. Objective: This was to assess the feasibility and suitability of the intranasal route for administering pharmacological therapy in the prehospital management of patients experiencing psychomotor agitation. Materials and Methods: An integrative review of the literature was conducted to evaluate the use of the intranasal route for drug administration in patients with psychomotor agitation in prehospital settings. The review was carried out between September 2022 and July 2024. A total of 454 articles were identified, 15 of which met the inclusion criteria. These were supplemented by an additional 10 records, resulting in the analysis of 25 studies. Results: Seventeen studies outlined protocols for managing agitated patients, five described the correct technique for intranasal drug administration, and eleven identified drugs suitable for this route. Conclusions: The intranasal route is a safe, rapid, and accessible method for the pharmacological containment of agitated patients in prehospital settings, particularly for individuals who are uncooperative.

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

Additional Routes of Drug Administration
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...
Drug Delivery: Miscellaneous Routes
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

Drug Delivery: Parenteral Route
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
