Mens de tidligere kjente prostaglandiner ved mange anvendelses-måter bare viser en kort varighet for den biologiske virkning, utmerker de i henhold til oppfinnelsen fremstillbare nye forbindelser seg ved siden av_en-spesifikk virkning ved frem-bringelse av pro.staglandin-liknende reaksjoner også ved en betraktelig lengere virkningstid. Som følge av den lengere virkningstid er det ved de nye forbindelser tilstrekkelig med færre og mindre doser for å oppnå en bestemt virkning. For--de nevnte-.formål tilføres de nye forbindelser i forskjellige, doseringsformer, for eksempel oralt i form.av While the previously known prostaglandins in many ways of application only show a short duration of the biological effect, the new compounds that can be prepared according to the invention excel in addition to a specific effect in producing prostaglandin-like reactions also in a significantly longer duration of action. As a result of the longer duration of action, with the new compounds fewer and smaller doses are sufficient to achieve a specific effect. For the aforementioned purposes, the new compounds are supplied in different dosage forms, for example orally in the form of

tabletter, kapsler eller væsker, rektalt i form av supposi- tablets, capsules or liquids, rectally in the form of suppositories

torier eller subkutan, intramuskulært eller Intravenøst.tories or subcutaneously, intramuscularly or intravenously.

Som medisin kan de nye forbindelser tilføres i egnet preparat-form med farmakologisk indifferente hjelpestoffer. 1 de etterfølgende eksempler som skal illustrere oppfinnelsen er alle temperaturangivelser i grader -celsius.
