Abstract:
A method of orally administering a pharmaceutical composition, said method comprising orally administering to a patient in need of cyclosporin therapy a composition comprising about 5 to about 25% by weight of cyclosporin A, about 0.5 to about 90% by weight of a hydrophilic component other than the hydrophilic surfactant, about 0.5 to about 90% by weight of a lipophilic component and about 0.5 to about 90% by weight of a hydrophilic surfactant other than the hydrophilic component, all weight percents being based on the total weight of the composition, the relative proportion of said cyclosporin A, hydrophilic component, lipophilic component and hydrophilic surfactant being such that upon dilution of the composition with adequate water, an oil-in-water microemulsion having particles of less than 2,000 .ANG. is spontaneously formed.
