Abstract
Background: Antibiotics are essential for the treatment of bacterial infections and are considered among the most commonly sold drug classes from the community pharmacy in the developing countries without a prescription in most cases. Purpose: This study aims to explore the knowledge, practices, and attitudes regarding antibiotic use. Materials and methods: This study employs a cross-sectional descriptive design that used a pre-validated survey. The participants were classified into three main mutually exclusive groups: healthcare professionals, medical students, and other adults in the community.Entities:
