Resumen

Los objetivos de este estudio son: 1) valorar el patrón de distribución anatómica de un gel tópico liberado en la cavidad nasal en pacientes con y sin inflamación nasal y 2) determinar si esta distribución se ve influida por la dosis o la técnica de liberación. Se estudiaron 39, 26 sin inflamación y 13 con inflamación nasal, que se administraron un gel teñido de forma diferente en cada fosa. En una de forma adecuada y el la otra de forma inadecuada y con dosis doble. Los hallazgos mostraron que el gel administrado no sobrepasa de la porción inferior del cornete medio, ni llega a la mucosa olfatoria, independientemente del modo de administración o el estado de la mucosa

Abstract

The objectives of this study are: 1) to assess the anatomical distribution of a topical liquid nasal gel in patients with and without rhinitis using a metered dose nasal pump, and 2) to determine whether the distribution pattern is influenced by dosage and delivery technique.Thirty-nine volunteers were evaluated, 26 without nasal inflammation and 13 with rhinitis. Patients self-administered the nasal spray according to the specifications in one fossa and incorrectly in the other one (sniffing and double doses). The findings showed that the nasal gel delivered by spray did not penetrate beyond the inferior part of the middle turbinate, regardless of delivery technique (double dose with sniffing or single dose without sniffing) and the presence or absence of inflammation
