A suspendible composition comprising a tricyclic compound such as FK 506 substance which is 17-allyl-1,14-dihydroxy-12-[2-(4-hydroxy-3-methoxycyclohexyl)-1-methylviny l]-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo-[22.3. 1.0.sup.4,9 ]octacos-18-ene-2,3,10,16-tetraone, or the like, and a pharmaceutically acceptable surfactant, which can be used as an orally administrable agent or eye drops and is useful for treating various diseases.

Suspendible composition and process for preparing the same

An ointment comprising a tricyclic compound such as FK 506 substance which is 17-allyl-1,14-dihydroxy-12-[2-(4-hydroxy-3-methoxycyclohexyl)-1-methylviny l]-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo[22.3.1 .0.sup.4,9 ]octacos-18-ene-2,3,10,16-tetraone, or the like, a solubilizing and/or absorption-promoting agent and an ointment base, which is useful for treating various skin diseases.

Ointments containing FK-506 or derivatives thereof

A suspendible composition comprising a tricyclic compound such as FK 506 substance which is 17-allyl-1,14-dihydroxy-12-[2-(4-hydroxy-3-methoxycyclohexyl)-1-methylviny 1]-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo[22.3.1 .0.sup.4,9 ]octacos-18-ene-2,3,10,16-tetraone, or the like, and a pharmaceutically acceptable surfactant, which can be used as an orally administrable agent or eye drops and is useful for treating various diseases.

Sustained-release percutaneous preparations which have at least two adhesive layers and in which a drug is contained in the layer farthest from the skin and a solid powder is dispersed in an adhesive layer other than the layer farthest from the skin provide slow release of the drug. By varying the kind and concentration of the solid powder, the rate of release of the drug from the preparations can be controlled.

Sustained-release percutaneous preparations

The invention relates to a sustained-release transdermal delivery preparation which comprises a slow-release microcapsule containing 2-nitroxymethyl-6-chloropyridine or its occlusion compound with .beta.-cyclodextrin and a skin-compatible base.
