ABSTRACT
Generic medications contain the identical active ingredient in the same concentration as their branded counterparts and are administered in the same manner, aiming to deliver comparable efficacy, dosage, and clinical outcomes. Nevertheless, variations in additives and formulation processes, particularly noticeable in topical medications, can influence factors like ease of use and patient adherence. Therefore, in this study, we aimed to compare the rheological attributes of branded and generic injectable ointments, assessing disparities in formulation performance and their impact on patient care. Posterisan® Forte and Hemoporison® ointments were used as the branded and generic versions, respectively, and their viscosity, ductility, and viscoelastic properties were evaluated. Posterisan® Forte showcased enhanced spread ability, maintaining uniform flow characteristics across varying temperatures, whereas Hemoporison® displayed pronounced thixotropic properties and stiffness, suggesting potential benefits for applications necessitating reversible viscosity adjustments and heightened rigidity. Despite sharing identical additives, observable differences in physical characteristics highlight the necessity of understanding formulation traits, which could influence ointment behavior. Alterations in fluidity and viscosity may affect how patients perceive and apply the medication, potentially influencing treatment outcomes and the occurrence of adverse effects.
