A fluid carrier comprises first and second substantially immiscible liquids. The first liquid is an open chain silicone oil of the formula [(CH)Si O] [(CH)Si O] [Si(CH)]. The second liquid is a polar lipid material. The first and second liquids are capable of forming an unstable dispersion. The unstable dispersion can be stabilized by adding a powderous solid insoluble in the liquids. The powderous solid is selected from pharmacologically active agent pharmaceutical excipient and their mixtures. The stabilized dispersion is of a creamy or ointment like or mouldable form and can be filled into capsules or moulded into tablets so as to be fit for peroral administration.
