Abstract

La prilocaïne basique, sous forme liquide et sous forme de cristaux en microbâtonnets, peut être solubilisée dans des agents de propulsion aux hydrofluorocarbures pour donner un liquide huileux et stable. La prilocaïne basique peut être utilisée pour solubiliser, dans des agents de propulsion de ce genre, des médicaments additionnels qui, habituellement, ne sont pas solubles. L'association de prilocaïne basique et d'un agent de propulsion à l'hydrofluorocarbure peut être utilisée comme brouillard sous forme d'aérosol, pour produire une anesthésie topique.
