Biodisponibilidad de corticoides fluorados en preparaciones semisólidas

Abstract

In the present work a study on the bioavailibity of three fluorate corticoids contained in various semisolid preparations have been carried out. The medicinal substance submítted to the assay, Flupamesona, Fluprednyliden y Formocortal, have been included in two usual excipients, the Hydrophilic Ointment and the Polyethyleneglycol. Furthermore, three commercial formulations in whích they are contained, were assayed. The test carried out in all of them are of two kinds: - "In vitro", following the technique of cession in isopropyl myristate. - "In vivo", foUowing the procedure of vasoconstricción and bleaching of McKENZIE and STOUGHTON. From the results obtained we verify that the Hydrophilic Ointment shows better properUes of cession, even better than the formulations which are available in the pharmaceutical market. Likewise, from the three corticoids assayed, the Fomocortal shows a greater vasoconstricting activity, being followed by the Fluprednyliden; the Flupamesona 1s found in the last position.

En el presente trabajo se ha realizado un estudio de la biodisponibillidad de tres corticoides fluorados contenidos en diversas preparaciones semisólidas. Las sustancias medicamentosas objeto de ensayo, Flupamesona, Flupredniliden y Formocortal, se han incluido en dos excipientes usuales, el Hydrophilic Ointment y el de Polyethileneglycol, ensayándose además tres formulaciones comerciales que los contienen. Las pruebas efectuadas en todas ellas son de dos tipos: - "In vitro", según la técnica de cesión en miristato de isopropilo. - "In vivo", por el procedimiento de vasocontricción o emblanquecimiento de McKENZIE y STOUGHTON. De los resultados obtenidos se comprueba que el Hydrophilic Ointment presenta mejores características de cesión, superiores incluso a las formulaciones del mercado farmacéutico. Asimismo, de los tres corticoides ensayados, el Formocortal presenta mayor actividad vaso constrictora, siguiéndole el Fluprednyliden, y encontrándose en último lugar la Flupamesona.
