Abstract

Farmasøytiske sammensetninger for administrering av en aktiv substans til eller gjennom en skadet eller uskadet hud eller mukosaoverflate eller til det orale hulrommet inkludert tennene til et dyr slikt som et menneske. Blandingen har fordelaktige egenskaper med hensyn på frigjøring av den aktive substansen fra blandingen og, videre, er blandingen bioadhesiv. Blandingen innbefatter den aktive substansen og en effektiv mengde av en fettsyreester som, sammen med en flytende fase, kan generere en flytende krystallinsk fase der bestanddelene av blandingen er innesluttet, der den aktive substansen har en løselighet i den flytende krystallinske fasen på det meste 20 mg/g ved 20 °C, og en løselighet i vann på det meste 10 mg/ml ved 20 °C, vannet, der det er passende, er bufret til en pH som er vesentlig lik den pH som er rådende i den flytende krystallinske fasen (pH ca. 3,6-9). Blandingen er spesielt egnet for administrering av substanser som har en veldig lav vannløselighet og som skal bli gitt i en effektiv mengde til en lokalisert region over en tidsperiode. Aktive substanser med spesiell viktighet er anti-herpesvirusagenser inkludert antivirale legemidler og prodroger derav, slik som nukleosider, nukleosid- analoger, fosforylerte nukleosider (nukleotider), nukleotidanaloger og salter, komplekser og prodroger derav; f.eks. guanosinanaloger, deoksyguanosinanaloger, guanin, guaninanaloger, tymidinanaloger, uracilanaloger og adeninanaloger. Spesielt interessante anti-herpesvirusagenser til bruk enten alene eller i kombinasjon i en blanding i henhold til den foreliggende oppfinnelsen er valgt fra acyklovir, famciklovir, deciklovir, penciklovir, zidovudin, ganciklovir, didanosin, zalcitabin, valaciklovir, sorivudin, lobukavir, brivudin, cidofovir, n-dokosanol, ISIS-2922, og prodroger og analoger derav.Pharmaceutical compositions for the administration of an active substance to or through an injured or undamaged skin or mucosa surface or to the oral cavity including the teeth of an animal such as a human. The composition has advantageous properties in releasing the active substance from the composition and, further, the composition is bioadhesive. The composition includes the active substance and an effective amount of a fatty acid ester which, together with a liquid phase, can generate a liquid crystalline phase where the constituents of the mixture are enclosed, the active substance having a solubility in the liquid crystalline phase of at most 20 mg. / g at 20 ° C, and a solubility in water at most 10 mg / ml at 20 ° C, where appropriate, the water is buffered to a pH substantially equal to the pH prevailing in the liquid crystalline phase (pH about 3.6-9). The mixture is particularly suitable for the administration of substances which have a very low water solubility and to be delivered in an effective amount to a localized region over a period of time. Active substances of particular importance are anti-herpes virus agents including antiviral drugs and prodrugs thereof, such as nucleosides, nucleoside analogs, phosphorylated nucleosides (nucleotides), nucleotide analogs and salts, complexes and prodrugs thereof; eg. guanosine analogues, deoxyguanosine analogs, guanine, guanine analogs, thymidine analogs, uracil analogs and adenine analogs. Particularly interesting anti-herpes virus agents for use either alone or in combination in a composition of the present invention are selected from acyclovir, famciclovir, deciclovir, penciclovir, zidovudine, ganciclovir, didanosine, zalcitabine, valaciclovir, sorivudine, lobucavir, brivudine n-docosanol, ISIS-2922, and prodrugs and analogs thereof.
