Abstract

Si tratta di aggregati stabili, caratterizzati dal fatto di consistere in almeno un derivato di purina, ad esempio 9-(2-idrossietossimetil)-guanina, contenuto tra le lamelle e/o all'interno del doppio strato fosfolipidico di globuli liposomiali, essendo le concentrazioni in percentuale in peso del derivato purinico e dei liposomi rispettivamente comprese negli intervalli 1-35% e 65-99%. Sono oggetto dell'invenzione anche le composizioni farmaceutiche caratterizzate dal fatto di contenere come principio attivo almeno un derivato di purina in forma di detto aggregato.
