Aerosol compositions

The use of a medium-chain fatty acid triglyceride as the dispersant in the preparation of a medicinal aerosol composition comprising tricyclic compound (I) dispersed in a liquefied hydrofluoroalkane propellant is described. When a liquefied hydrofluoroalkane is added to a kneaded premix of the tricyclic compound (I) and a medium-chain fatty acid triglyceride, the active ingredient is evenly dispersed in the liquefied hydrofluoroalkane. Therefore, by distributing a dispenser first with the kneaded premix and, then, with a liquefied hydrofluoroalkane under cooling or elevated pressure, there can be provided a medicinal aerosol composition having an improved uniformity of content of the active ingredient.

A lotion comprising a tricyclic compound, typically 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 a pharmaceutically acceptable salt thereof, a solubilizing and/or absorption-promoting agent, a liquid medium, and optionally an emulsifier and/or a viscosity increasing agent. The lotion is stable, excellent in absorption and has less irritation against the skin and sustained release. Also, the lotion is effective for the treatment and/or prophylaxis of inflammatory and hyperproliferative skin diseases and cutaneous manifestations of immunologically-mediated illnesses.

The invention relates to a delayed action preparation which comprises a core comprising a drug and a swelling agent and an outer membrane comprising a biodegradable high molecular weight substance characterized in that the swelling agent is contained in a sufficient amount to cause a explosion of the outer membrane of biodegradable high molecular weight substance at a definite time after administration. This preparation provides for free control over the timing of drug release and is suited for administration not only by the oral route but also by the intramuscular, subcutaneous and other routes.
