Management of Acute Upper Respiratory Tract Infection: Role of Early Intervention
Main Article Content
Abstract
Acute upper respiratory tract infections (URTIs) are caused by viral or bacterial infections of the nose, sinuses, pharynx, and larynx. The majority of acute URTIs are usually short-term and self-limiting with mild symptoms. However, in some cases, it can lead to serious complications and socioeconomic problems for both individuals and society. Treatments for acute URTIs are mainly symptom-based for example decongestant drugs and nasal congestion relief, antihistamine or antiallergy, antipyretic such as paracetamol, oral nonsteroidal anti-inflammatory drugs, expectorant, antitussive, etc. The technologies for early intervention to prevent worsening symptoms are limited. Currently, innovative polymer nasal sprays are in clinical studies to show their efficacy when used for early intervention of acute upper respiratory tract infections. These sprays trap various virus particles to protect viral penetration in tissues to reduce severity and infection. Hence, an innovative polymer nasal spray to reduce the severity and duration of URTIs can add benefit to current treatments.
